DOI:
Objective: Octreotide was labeled with 99mTc, to analyse radiochemical characters of 99mTc-Octreotide and investigate the clinical receptor imaging in patient with Graves’ ophthalmopathy(GO). Methods: Labeling was accomplished by reduction of the cysteine bridge, which provided sulfhydryl groups for chelation with 99mTc. The labeling rate was determined with Xinhua I chromatography. The radiochemical property of　99mTc-OCT were evaluated by Sep pak Cl8 chromatography, the cysteine challenge experiment, the serum incubation test and the stability experiment in vitro and the clinical procedures of receptor fusion imaging were carried out in patient with GO. Results: The labeling rate of 99mTc-OCT was (95.8±0.55)％, the 99mTc-OCT compound has excellent radiochemical characters. SRS showed markedly increased orbital uptake of 99mTc-OCT in patient with active GO. Conclusion: 99mTc-OCT can be readily prepared, the labeling yields are quite high(>95％), and stability in vivo(vitro); 99mTc-OCT is a promising radiopharmaceutical for somatostatin receptor scintigraphic imaging.

MA Guo-jun;YU Shu-jing;LI Zhong-xin
DOI:
Objective: To assess the value of 64 multislice spiral CT for evaluation of the origin of coronary artery anomalies and prognosis. Methods: 1211 patients undergone coronary artery CT angiography(CTA) were reviewed for this study. Results: In consecutive 1211 patients, 64 MSCT identified 18 cases(2.17%) with an anomalous origin of the coronary artery, including anomalous origin of the right coronary artery from left coronary sinus(n=5), anomalous high origin of the right coronary artery(n=1), separate origin of CB from right sinus(n=4), anomalous origin of the left coronary artery from right coronary sinus(n=3), left circumflex coronary artery from right sinus(n=1), separate origin of left circumflex coronary artery and left anterior descending arteries from left coronary sinus(n=5). Three coronary arteries in 8 patients with anomalous origin showed mild stenosis. Conclusion: Noninvasive 64 MSCT can detect the anomalous origin of the coronary artery with high resolusion, and can evaluate the prognosis of the anomalous origin coronary artery.

SHI Yu;GUO Qi-yong;WANG Xiao-ming
DOI:
Objective: To assess whether hepatic diffusion measurements are influenced by hepatic perfusion changes due to different b values in both posterior and anterior segments of right lobe. Materials and Methods: DWI was performed on a 1.5T MRI unit among 26 healthy volunteers after an 8h fast and 1h after a standard meal(which is regarded as an effective method to increase hepatic perfusion including portal venous flow and hepatic sinusoidal perfusion), we used a breath-hold technique for 20.5s at b-values of 750, 500 and 250 and 0s/mm2. The hepatic apparent diffusion coefficient(ADC) values were measured and compared due to different prandial states in both posterior and anterior segments of right lobe. Results: Compared the two sets of ADCs before and after meal, the ADC measurements using b=750s/mm2 in both posterior and anterior right lobe were unaffected by the perfusion changes(t=1.419, P=0.178; t=1.943, P=0.072) whereas the ADC values from b=250s/mm2 increased significantly after meal in both posterior and anterior segments of right lobe(t=3.839, P=0.002; t=5.178, P<0.001). As for b=500s/mm2, only the ADCs in the posterior right lobe was unchanged significantly after meal(t=1.519, P=0.151)　when compared to the significantly changed ADCs in the anterior right lobe(t=2.449, P=0.028). Conclusion: With regard to the measurements of ADC, the effect of perfusion can be minimized at the higher b values(b≥500s/mm2) and in the posterior right lobe at the fasted state, which may offer the most consistent ADC values and optimized measuring conditions for further studies of hepatic DWI.

CHU Hong-gang;SU Li-hua;GUO Rui-qiang;SUN Bin;JIANG Xia;SUN You-gang
DOI:
Objective: To determine whether there is an association between the presence of aortic valve calcification(AVC) and carotid artery atherosclerotic disease. Methods: 214 patients with AVC diagnosed by transthoracic echocardiography underwent carotid artery ultrasound at the same time. They were compared with 182 age- and sex-matched persons without AVC who underwent carotid artery ultrasound during the same period. Results: ①Compared with the control group, the AVC group showed a significantly higher prevalence of systolic blood pressure(SBP) and diastolic blood pressure(DBP)[(162±18)mmHg versus (120±14)mmHg, P<0.01; (101±16)mmHg versus (78±12)mmHg, P<0.01). ②IMTs of CCA and ICA in the AVC group were significantly thicker than that in the control group[(1.17±0.18)mm versus (0.90±0.10)mm, P=0.000; (1.06±0.18)mm versus (0.81±0.12)mm, P=0.000, respectively].③Compared with the control group, the AVC group showed a significantly higher prevalence of carotid atherosclerotic plaque(44.39% versus 18.13%, P=0.000). ④The AVC group showed a significantly higher prevalence of carotid stenosis ≥20%(78.50% versus 57.14%, P=0.000), ≥40%(36.45% versus 22.53%, P=0.003), ≥60%(15.42% versus 8.24%, P=0.029), and ≥20%(38.32% versus 22.53%, P=0.001), ≥40%(19.63% versus 9.89%, P=0.007), ≥60%(7.01% versus 1.10%, P=0.004) of bilateral carotid artery. ⑤Vm of CCA and ICA in the AVC group were decreased significantly than that in the control group[(30.26±7.83)cm/s versus (41.25±8.32)cm/s, P=0.000; (35.46±6.85)cm/s versus (47.36±11.35)cm/s, P=0.000]. But PI(1.64±0.48 versus 1.35±0.32, P=0.010; 0.96±0.28 versus 0.85±0.16, P=0.039) and RI(0.78±0.07 versus 0.65±0.06, P=0.000; 0.81±0.11 versus 0.60±0.05, P=0.000) of CCA and ICA in the AVC group were increased significantly than that in the control group. ⑥On multivariate analysis, AVC was the only independent predictor of carotid atherosclerotic disease(stenosis of ≥40%, P=0.004). Conclusions: There is a significant association between the presence of AVC and carotid artery atherosclerotic disease. AVC may be an important marker for atherosclerotic disease of the carotid arteries. Carotid artery high frequency ultrasound should be underwent to the patients with AVC diagnosed by transthoracic echocardiography as a common.

550 Quantitative evaluation of left ventricular myocardial systolic dyssynchrony in patients with heart failure by TVI, SI, SRI and RT-3DE
LI Yu-feng;REN Wei-dong;JI Ri;ZHOU Jie-ying;YAN Hua;CHEN Xin;CHENG Yan-bin
DOI:
Objective: To evaluate left ventricular myocardial systolic dyssynchrony in patients with heart failure(HF) by tissue velocity imaging(TVI), strain rate imaging(SRI), strain imaging(SI) and real-time three-dimensional echocardiography(RT-3DE). Methods: Fifty-seven subjects were divided into two groups. Group A consisted of 27 normal subjects, and group B included 30 patients with HF. Patients in group B were divided into three subgroups according to LVEF and two subgroups on the basis of QRS width. The former consisted of mild(6), moderate(18) and severe(6) HF patients, and the latter included narrow QRS subgroup(22) and wide one(8). Tissue Doppler imaging(TDI) and full volume were performed with Philips IE33. The times to the point of peak velocity(Tv), strain rate(Tsr), strain(Ts) during systolic phase, to the point of minimal volume(Tmv) and cardiac cycle were obtained by the on-line Qlab software. The LVEF was derived from RT-3DE. Results: LV systolic dyssynchrony in patients with HF was evaluated by TVI, SRI, SI and RT-3DE. There was significant difference in normal subjects, mild, moderate and severe HF patients(P<0.05). Curves in group A arranged orderly by TVI, SRI, SI, and RT-3DE, while that in group B ranked disorderly. There was no significant difference of SDI between wide QRS subgroup and narrow one. Significant negative correlation existed between LVEF and SDI, where RT-3DE and TVI appeared better than SRI and SI. Conclusion: All the TVI, SRI, SI and RT-3DE can evaluate LV systolic dyssynchrony noninvasively and quantitatively, but RT-3DE can provide a novel, quick and convenient technique.

LU Na;GUO Qi-yong;REN Ying;BI Chun-long;CHEN Li-ying
DOI:
Objective: To assess the feasibility of 64-CT perfusion of normal pancreas and compare the perfusion parameters between normal pancreas and pancreatic cancer. Methods: Twenty-four healthy subjects and 35 patients with pancreatic cancer underwent CT perfusion on a 64-slice CT of Siemens. The raw data was calculated with Siemens software and the perfusion characteristic parameters(including BF, BV, PE, TTP, P) were compared. Results: Pancreatic cancer showed higher P and lower BF, BV and PE compared with those of normal pancreas. Cancer tissue showed lower BF, BV and PE, but higher TTP and P compared with normal tissue in the same patient(P<0.05). Pancreatic cancer type 2, 3, 4 showed higher P compared with type 1(P<0.05). Conclusion: CT perfusion is a feasible technique to assess pancreatic blood perfusion. Comparation of perfusion parameters of normal tissue and pancreatic cancer tissue of the same patient can be a good option in the diagnosis of pancreatic cancer. Permeability can assess the degree of blood vessels destruction.

DOI:
Objective: To evaluate the value of MRI and CR in the diagnosis of healing process of vertebral fracture. Methods: Twenty-one healthy adult female rabbits of the same age and weight were selected, firstly, animal models of vertebral fracture were made by operation, then they were examined with CR and MRI at 24 hours, 72 hours, 1 week, 2 weeks, 4 weeks, 6 weeks, 8 weeks respectively. MRI/CR manifestations and pathological appearances were analyzed. Results: With the repairing of the fractured vertebra, on CR, the low density band was substituted by high density band, the density of the fractured vertebra increased, and in the end, resumed equal to the adjacent vertebra. On MRI, the low signal intensity on T1WI and high signal intensity on T2WI resumed isointense on T1WI and T2WI. Conclusion: CR has some value to the diagnosis of vertebral fracture and the healing process of the rabbit by analyzing density of the callus. The signal intensity of MRI could reflect the pathology of vertebral fracture of rabbit to some extent.

563 Evaluation of multislice CT virtual endoscopy in the diagnosis of nasopharyngeal carcinoma
ZHAO De-li;ZHANG Zai-ren;LIU Bai-lu;ZHANG Jin-ling
DOI:
Objective: In the present study, multi-slice computed tomography virtual endoscopy(MSCTVE) was evaluated in the diagnosis of nasopharyngeal carcinoma. Methods: Twenty-four patients with nasopharyngeal carcinoma and normal nasophrynx confirmed by pathology underwent multi-slice CT scanning performed with GE Prospeed16 and flexible endoscopy(FE). Two radiologists using Fly Through software generated both antegrade and retrograde endoluminal virtual endoscopy navigation of the nasopharynx. The results of the radiological study were compared with flexible endoscopic findings using six-point and four-point rating scale. Results: MSCTVE appeared to be more accurate in visualization and evaluation of nasopharyngeal anatomy and abnormalities caused by nasopharyngeal carcinoma(P<0.01), however depictions of mucosal surface were difficult or inaccurate(P>0.05). There was good overall correlation between virtual images and flexible endoscopic findings. Conclusion: MSCTVE is a new radiographic technique that can depict clearly the anatomy and morphological changes in nasopharyngeal carcinoma. This technique is undergoing rapid growing, however there are some limitations such as characterization of lesion and inability to obtain biopsy. We are of the opinion that MSCTVE is a non-invasive and useful technique for nasopharyngeal carcinoma in diagnoses and clinical practice.

575 Experimental research for the evaluation of radiotherapeutic response with 99Tcm-HL91 hypoxia imaging
DU Xue-mei;ZHANG Yan-jun;TAO Li;JU Zai-shuang;ZHANG Xin;DENG Xiao-qin
DOI:
Objective: The aim of this study was to evaluate the radiotherapeutic response with 99Tcm-HL91 hypoxia imaging in mice bearing Hca-F25 tumor cells. Methods: All the mice bearing Hca-F25 tumor cells were divided into the irradiation group and the control group. The irradiation group were irradiated at a dose rate of 300MU/min with 6MeV linear accelerator; each irradiation dose was 15Gy. The control group weren’t irradiated. All the mice were injected intravenously with 0.1ml(37MBq) of 99Tcm-HL91 before radiotherapy, 3d and 5d after radiotherapy. Imaging was carried out 4 hours later and the tumor-to-normal ratio(T/NT) was calculated. Tumor length(A) and maximum vertical diameter(B) were measured before each imaging and caculated tumor volumes(mm3). At the end of the study, the weight and radioactivity of the tumors were measured. Percent of necrotic area(PNA) was calculated through hematoxylin-eosin(HE) staining of the tumor sections. Results: Tumors had good images. T/NT, Rv3, Rv5, tumor volumes and weights in the irradiation group were all obviously lower after irradiation than that in the control group(P<0.05), but PNA was on the opposition(P<0.05). T/NT before treatment was not correlated with Rv5 and PNA(P>0.05). Increased T/NT 3d after irradiation had positive correlation with Rv5, and negative correlation with PNA(P<0.05). Irradiation 3d later, the average Rv5 of uptake in the increased subgroup was more than that of uptake in the decreased subgroup, but the PNA was quite the reverse, there were significant differences(P<0.05). Conclusions: 99Tcm-HL91 image after irradiation was able to evaluate the radiotherapeutic response.

LIU Jing-hong;GAO Si-jia;SHI Qiang;FU Qiang
DOI:
Objective: To explore the effect of perfusion parameters of input different artery in the reconstruction of CT perfusion imaging. Materials and Methods: Thirty-five patients including 8 normals, 27 unilateral middle cerebral artery(MCA) stenosis patients were collected perform normal brain CT scan and CT perfusion imaging. They all had brain CT perfusion imaging after normal brain CT scan. In the reconstruction of cerebral CT perfusion, every data was reconstructed 3 times and the anterior cerebral artery(ACA) were chosen, uninjured side(stroke patients) or left(normal) MCA and injured side(stroke patients) or right(normal) MCA to be input artery respectively, and choosed superior sagittal sinus to be output vein. Drawed region of interest（ROI） in the cortical area of each side and recorded cerebral blood flow(CBF), cerebral blood volume(CBV), and mean transit time(MTT) of ROI. Three data was analysed with one-factor analysis of variance. Results: There is no statistic difference among all parameters in the normals. Otherwise there is statistic difference among all CBF and MTT in unilateral stroke in MCA patients, and there is no statistic difference among CBV. Conclusion: In the reconstruction of cerebral CT perfusion, any large artery can be chosen as input artery in normals, otherwise in the unilateral MCA stenosis patients, the normal ACA should be chosen as input artery.

WEN Xiao-rong;KUANG An-ren;LUO Yan;PENG Yu-lan
DOI:
Objective: This study was undertaken to explore different patient positions(supine position and standing position) by color Doppler flow image(CDFI) measuring chronic venous incompetence(CVI) quantitatively. Methods: Thirty-nine impaired lower limbs in 25 patients and 12 healthy limbs in 10 patients were tested in supine position and standing position. Great saphenous vein(GSV), common femoral vein(CFV) and superficial femoral vein(SFV) were evoked reflux by Valsalva method, and popliteal vein(POPV) by compression maneuver. Reflux time(RT, s) and peak reflux velocity(PRV, cm/s) were measured. The total RT, total PRV and the number of reflux segments were calculated. Results: All of the segments’ RT are less than 0.5s despite supine position and standing position in healthy group. No meaningful difference about the number of reflux segments is found between supine and upright. The overall RT of supine position is significantly longer than that of standing position. The overall PRV has no significant difference between supine and standing position. The diameters of GSV, CFV, SFV and POPV of the patients and healthy group in standing position are significantly wider than that in supine position. Conclusion: We can evaluate CVI by CDFI with patients in supine position or upright, but it is more convenient that the patients are in supine position. Supine position might be the first choice for detecting CVI for the old, incapable and the person who can not stand for long time.

DOI:
Objective: To describe the normal appearance of the sternal area on bone scintigraphy. Methods: 120 patients, who did not have symptoms of the sternum or a history of malignancy, underwent whole-body bone scan and were evaluated for characters of sternal uptake. Results: ①In pediatric patients, their character was similar, and sternal uptake was homogeneous. In other patients, the sternum showed markedly different, and seven different patterns of sternal uptake were noted. ②The most common hot spot was at the angle of Louis, and there was focal spot of decreased tracer uptake in the lower sternum. Conclusion: This study showed age-related normal variants of sternal uptake. Understanding these variants may be helpful in differentiating normal and abnormal patterns of uptake in the sternum on radionuclide bone imaging.

CHEN Kun-tao;HE Jian-yuan;GUO Rui-zhen
DOI:
Objective:　To investigate the correlation between CT perfusion features and tumoral angiogenesis of rabbit bearing VX2 tumor before and after chemoembolization. Materials and Methods: Sixty New Zealand white rabbits, the rabbits were injected with VX2 tumor piece into the left lobe of the liver. Fourteen days after implantation the 60 rabbits were divided into contrast group(n=30) and chemoembolization group(n=30) randomly. CT perfusion was performed in the two groups. MVD and expressions of VEGF were examined by immunohistochemical techniques. Statistic analysis was made. Results: There were positive correlation between CT perfusion parameters with MVD and expressions of VEGF. CT perfusion parameters, MVD and expressions of VEGF of the chemoembolization group was lower than those of the contrast group. Conclusions: CT perfusion features can reflect tumoral angiogenesis indirectly, and can estimate the effect of chemoembolization.

Objective: To discuss the method of scanning and image reconstruction with MSCT in lumbar spondyloschisis. Methods: Twenty-six patients were scanned with CT for the intervertebral disc. The scan range were enlarged for L4~5, L5~S1 interverteral disc and including vertebral arch. Spiral scan were performed in 10 cases. The images were reconstructed with multiplanar reformation(MPR) and maximum intensity projection(MIP) along the direction of vertebral arch. Results: Axial scanning including vertebral arch can show spondyloschisis and other signs. These contained widened or stenosis of the spinal canal, stenosis of the lateral recess, the double margin sign, deformity of the intervertebral disc, denegeration of the joint facet and thickening of the ligamentum flavum. Scotty dog sign were showed in images reconstructed along the direction of vertebral arch. Spondylolysis were showed in sagittal images. Conclusion: The scan range were increased for the fourth lumbar to first sacroiliac interverteral disc and contained vertebral arch for conventional intervertebral disc. The spiral scanning were performed for lumbar spondyloschisis and with MPR along the direction of vertebral arch. The method is simple and useful for the patients suffered low-back pain.
