241 Studying on ocular hemodynamics in myopia with color Doppler flow imaging
GOU Shan;GONG Wei-bing
DOI:
Objective: To study the hemodynamic changes of ophthalmic artery(OA), short posterior ciliary artery(SPCA), and central retinal artery(CRA) in patients with myopia. Methods: Fifty-two eyes in 26 patients with medium myopia, 44 eyes of 23 patients with severe myopia, and 50 eyes of 25 normal subjects were studied. Peak systolic velocity(PSV), end diastolic velocity(EDV) and resistance index(Rl) of OA, SPCA and CRA were measured in the 3 groups and comparison was carried out. Results: Compared to normal subjects, the patients with medium myopia and severe myopia showed a significant decrease(P<0.05) in the mean PSV and EDV of the CRA and SPCA, and a significant increase(P<0.05) in the mean RI of the CRA and the PCA, but there was no significant difference(P>0.05) in the OA for the 3 groups. Compared to the patients with medium myopia, the patients with severe myopia showed a significant decrease(P<0.05) in the mean PSV and EDV of the CRA and SPCA, and a significant increase(P<0.05) in the mean RI of the CRA. Compare to normal subjects, eye axes and eye pressure in myopia patients also showed a significant difference(P<0.05). Conclusion: In patients with myopia, there appears to be an association between decreased mean flow velocity and an increased mean resistive index in the ocular vasculature. Factors relating to both vasculature and eye pressure have an important role in the pathogenesis of myopia.

GU Jie-hong;WANG Hai-lin;CHEN Sheng-li;MO Lei
DOI:
Objective: To analyse and evaluate local invasion of gastric carcinoma by 16-slices spiral-CT. Methods: Twenty-seven patients with gastric carcinoma were scanned by 16-slices spiral-CT including plain scans and dual phase enhanced scans. Local invasion was assessed by using the transaxial scans and combining with the post-processing scans, then SCT findings were correlated with surgrical-pathologic staging. Results: Two patients with early stage of gastric carcinoma were missed on transaxial scans. The accuracy rate of judging local invasion was 63%. Combining the post-processing scans, there was no misdiagnosing case. The accuracy rate was 85.3%. Conclusion: The enhancing scan of 16-slices spiral-CT combining with reconstruction technique can improve the detection rate of small lesions, and it is reliable for judgement of invasion in stomach wall and peripheral infiltration, so that 16-slices spiral-CT can judge the local invasion of gastric carcinoma fairly well.

DOI:
Objective: To explore the clinical application of quantitative index-MFD(mean flow density) before and after contrast-enhanced ultrasound(CEUS) in evaluating the blood supply of hepatic tumor. Methods: Thirty-five hepatic solid lesions, 11 cases of hepatocellular carcinomas(HCC), 9 cases of metastatic liver tumors(MLT), 15 cases of hepatic hemangiomas(HCH), were examined with color power angiography(CPA) before enhanced ultrasonography, then they were examined with pulse-inversion harmonic(PIH) ultrasonographic imaging after an intravenous administration of SonoVue. MFD were calculated and analysed before and after enhanced ultrasonography respectively. Results: There were significant difference of MFD before and after enhanced ultrasonography in each group(P<0.05). The MFD of HCC(0.303±0.179) were obviously higher than HCH(0.093±0.064) in enhanced ultrasonography(P<0.05). There was no obvious difference between MLT and the other two groups separately. Conclusion: can provide an important information for differential diagnosis between HCC and HCH after CEUS.

ZHANG Hong;JIANG Ning-yi;CHEN Shao-xiong;LU Xian-ping;LIU Sheng;LIANG Jiu-gen
DOI:
Objective: Preoperative lymphoscintigraphy(LS) is important in localization of the sentinel lymph node(SLN). The present study evaluated the benefit of SPECT/CT in LS for the preoperative localization of the SLN. Methods: Twenty-one clinically negative patients with T1 or T2 oral squamous cell carcinoma were enrolled. LS underwent by SPECT/CT. Planar and fusion images were interpreted separately. Results: In all patients, SPECT/CT fusion images confirmed the localization obtained by planar images and skin marking. Moreover, in 9 of 21 patients, the fusion images improved or corrected the preoperative localization of the SLN on planar images: 7 nodes that had been identified only on fused images were located in basins other than or in addition to the basins identified on planar images, 1 node that was located closed to the injection site was hidden by its scattered radiation on planar imaging, and 1 node erroneously diagnosed that was also affected by injection radiation scatter. In addition, fusion images identified bilateral draining basins in 6 of the 21 patients, however planar images only in 1 of 21. The SLN were successfully revealed in planar and fused images, with a detection rate of 95.2% and 100% respectively. Histologic examination confirmed the metastatic involvement of the SLN in 4 of 21 patients, the SLN positive rate was 13.8%, and there were no false negatives. Conclusion: Our results showed the additional value of SPECT/CT fusion imaging to planar imaging and sharpen the localization of the SLN that are of clinically relevance to SLNB in patients with oral squamous cell carcinoma. And fusion images provide the topographic landmarks that may further facilitate surgical exploration.

CHEN Xiang-hua;FENG Xiang-fei;TANG Zheng-de;SHENG Jing;CHEN Chao-ting
DOI:
Objective: To investigate the roles of fluid shear rate(SRs) on atherosclerotic plaques in model rabbits through Doppler ultrasound imaging technique. Methods: The atherosclerotic plaques were made in 29 rabbits by undergoing balloon-induced abdominal aorta wall injury and then fed on a diet of high cholesterol. The parameters such as: intima-medial thickness(IMT), average image intensity correction(AIIc%), systolic velocity(Vs), systolic diameter of lumen(Ds) and so on were measured with ultrasound imaging before a diet of high cholesterol and half month, one month, two months, three months and four months after abdominal aorta wall injured. Then SRs was calculated as well. Results: IMT became thicker and thicker. After abdominal aorta wall injured, the SRs first became low and then high, finally became low. The values of SRs after abdominal aorta wall injured were different with that before a diet of high cholesterol(P<0.05). Conclusions: IMT, AIIc% were significantly related to the thickness of atherosclerotic plaques. Lower SRs was one of the factors important in the shaping of atheros-clerotic plaques, but higher SRs may make atherosclerotic plaques unstable.

JIA Fei-ge;ZHANG Li-na;WANG Shao-wu
DOI:
Objective: To evaluate the diagnostic value of diffusion-weighted imaging(DWI) apparent diffusion coefficient(ADC) and exponential diffusion coefficient(EDC) in differentiation of benign from malignant soft tissue tumors. Methods: Twenty-three patients with soft tissue tumors were studied by DWI. All DWI were performed with SE-EPI technique, which “b” was 0 and 300s/mm2. DWI was analyzed to obtain ADC and EDC of tumor parenchyma. Results: The average value of ADC was(1.86±0.19)×10-3mm2/s for malignant group and (1.64±0.15)×10-3mm2/s for benign group when “b” was 300s/mm2. The mean ADC in benign and malignant tumors had significant difference. The average value of EDC was (160.02±83.23)×10-3 for malignant group and (136.89±44.60)×10-3 for benign group when “b” was 300s/mm2. The mean EDC in benign and malignant tumors has no significant difference. Conclusion: ①ADC is helpful to distinguish malignant tumors from benign tumors when “b” is 300s/mm2. ②EDC has limited value in distinguishing malignant tumors from benign tumors.

GONG Yong-jin;ZHOU Jian-jun;ZHOU Kang-rong
DOI:
Objective: Exploring the imaging features of lymphoma of bone and evaluating their clinical value. Materials and Methods: Thirteen patients of lymphoma confirmed by surgery and pathology underwent conventional radiography, in whom 10 underwent CT scan, and 9 underwent MR imaging. The acquired images were reviewed and analysed retrospectively and correlated with surgical and pathological results. Results: Nine non-Hodgkin’s and 4 Hodgkin’s lymphoma affected spine(46%), acetabulum(15%) and long bones(39%) respectively. Common locations were the vertebral body of spine and diaphysis of a major long bone. Common appearances were a lytic(69%) and mixed-density(31%) lesion with most cases showing an infiltrative or moth-eaten pattern. Cortical destruction was seen in 11 parients(85%) but usually without extensive cortical destruction. Periosteal reaction was seen in 3 patients(23%). Soft-tissue masses were present in 7 patients(54%). Lymphomas are hypo-dense or isodense to muscle on CT with circumscribed or distinct margins. Lymphomas appear low in signal intensity on T1-weighted images and low to high in signal intensity on T2-weighted images. Soft-tissue masses appear low in signal intensity on T1-weighted images and slightly high in signal intensity on T2-weighted images without much variable and with usually mild, enhancement following Gadolinium-DTPA(Gd-DTPA) contrast material injection. Conclusion: Lymphoma of bone has an infiltrative or moth-eaten pattern lytic bone destruction associated with soft-tissue mass. Radiography, CT and MR imaging can suggest the diagnosis, particularly when slightly high in signal intensity on T2-weighted images of a soft-tissue mass without extensive cortical destruction.

TAO Xing-jun;LI Sen-hua
DOI:
Objective: To study the MR imaging features of intraspinal enterogenous cysts. Materials and Methods: Six cases of surgically-proven enterogenous cysts were reviewed and their MR imaging features were analyzed(four were male and two were female, age ranged from twelve to twenty-six, with a mean of seventeen years). All cases evaluated by MR with axial section on T1WI and sagittal section on T1WI and T2WI. Results: Four cysts were in the junction of thoraco-cervical spine, one cyst was in the cervical spine, one cyst was in the thoracic spine, all cysts were located in the midline. Six cysts were either isointense(4/6) or slightly hyperintense(2/6) compared to CSF on T1WI. All were isointense to CSF on T2WI. Conclusion: Enterogenous cysts are best delineated by MR imaging. On the base of MR signal features and its location, the lesion is suggestive of the diagnosis.

DOI:
Objective: To evaluate the clinical value of three dimensional contrast enhanced MRA(3D-CE-MRA) in the imaging of the diseased arteries in lower extremities. Methods: Sixty-eight cases of arterial diseases or trauma of lower extremities received 3D-CE-MRA with a bolus injection of 30ml Gd-DTPA via antecubital vein before operation. Different surgeries were performed on the lower extremities based on the imagings which were harvested by MIP reconstruction workstation. The diagnosis of 3D-CE-MRA before operation were compared with the results of vascular reconstruction surgeries of lower extremities. Results: Satisfactory images of the main arteries of the lower extremities were achieved by 3D-CE-MRA, with the demonstrating rate of 100%. The location, extension and degree of the arterial lesions could be clearly revealed on the 3D-CE-MRA images, and the diagnosis of 3D-CE-MRA were 95%(65/68) in accord with the surgical outcomes. Combining with Doppler ultrasonic examination of vascular diseases, the correct rate of clinical diagnosis of 3D-CE-MRA reached 99%(67/68). Meanwhile, the second branches of anterior tibial arteries and/or posterior tibial arteries were not well demonstrated on 3D-CE-MRA images, however, this had no influence on surgical options and its outcomes. Conclusions: 3D-CE-MRA could play an important role in the diagnosis and follow-up of the arterial diseases of lower extremities with such advantages as accuracy, non-invasion, safety, rapidness and reproducibility. It is especially valuable in arterial surgerical planning and has big clinical significance.
