DOI:
Objectives: To evaluate the diagnostic value of diffusion tensor imaging(DTI) in brain tumors with necrosis and abscesses. Materials and Methods?押 Nine brain abscesses, 12 glioblastomas, 10 metastases confirmed clinically or pathologically underwent conventional MRI and DTI. Average diffusion coefficient(ADC) value, fractional anisotropy(FA) value and map was calculated in the central portion. Results: On DTI, The abscesses displayed as hyperintense signal; but glioblastoma and metastasis all showed hypointense signal. On ADC map, the abscesses showed hypointense signal, the mean ADC value was (0.66±0.07)×10-3mm2/s, The difference between abscess and necrotic tumors was statistically significant(P=0.000<0.05); glioblastoma and metastasis all demonstrated as hyperintense signal. Abscess, glioblastoma, metastases and peri-edema all were depicted as hypointense signal on FA map. Conclusion: Abscesses show special hyperintense signal on DTI and have low ADC value. DTI is helpful in differentiating abscess from glioblastoma and metastasis.

SUN Xun;AN Rui;LI Shuo;HE Yong;WU Jun;ZHANG Jun
DOI:
Objective: To study and to compare the biological characteristic of 99mTc labeled somatostatin analogue 99mTc-HYNIC-TOCA with 99mTc-P829 in tumor model, and to discuss the possibility of diagnosing tumors with 99mTc-HYNIC-TOCA. Methods: TOCA was labeled with 99mTc using HYNIC as bifunctional chelator, EDDA and tricine as coligand. The nude mice bearing human small cell lung cancer underwent static whole body planar imaging after the injection of 99mTc-HYNIC-TOCA or 99mTc-P829. ROIs were drawn and the radioactivity ratios of target to non-target(T/NT) were calculated in every planar imaging. The dynamic biodistribution study was operated in Kunming mice and the percent uptake ratios(%ID/g) of two imaging agents in different tissue at different time were measured. Results: The radiochemical purity of 99mTc-HYNIC-TOCA could reach 94.2% and keep to 93.5% after 6h at room temperature. In the images of tumor bearing mice, two imaging agent were both mainly concentrated in kidney and tumor. In early images, the ratios of tumor to contralateral limbs(T/C) in 99mTc-HYNIC-TOCA group were higher than which in 99mTc-P829 group. The greatest ratios of T/C in two groups(7.45±0.40 and 5.71±0.69) were gained until 4h post-injection. In Kunming mice, the %ID/g of kidney in both groups were the highest and the half-clearance time in blood were less than 60min. The uptake ratio of 99mTc-P829 in liver was significantly greater than the ratio of 99mTc-HYNIC-TOCA(t=2.17, P<0.05). Conculusion: 99mTc-HYNIC-TOCA and 99mTc-P829 could be highly uptaken in tumor and quickly cleared from blood. Both of these two imaging agents have good prospect in diagnosing tumors with SSTR expression.

DOI:
Objective: To evaluate indications, technical procedure and clinical efficacy of interventional treatment of secundum ASD complicated with other malformations under echocardiographic guidance. Methods: From October 1998 to October 2004, 428 patients with secundum ASD, 150 males, 278 females, at a mean age of (26.6±16.6)years(ranged from 2 to 30 years old) with a mean weight of (51.1±18.2)kg(ranged from 11 to 110kg) were studied. All ASD were central, including single-fenestrated ASD(n=416) and multi-fenestrated ASD(n=12). In addition to ASD, 70 patients accompanied with other malformations. These abnormities included pulmonary stenosis(n=14), pulmonary hypertension(n=11), mitral valve stenosis(n=3), supraventricular tachycardia(n=3), atrial fibrilation(n=14). Detecting frequencies of ultrasound instruments(CDFI) Toshiba 6000, Japan, and HP 1500, America) were 2.5MHz and 5.0MHz respectively. Diagnosis was determined with transthoracic echocardiography before the interventional procedure, which was performed under the support of transesophageal echocardiography in adult and transthoracic echocardiography in children less than 10 years old. Results: The maximum diameter of ASD was measured by the expanding balloon diameter under echocardiographic guidance, position and number was decided by transesophageal echocardiography or transthoracic echocardiography. Devices were successfully implanted into 425(99.3%) of the 428 patients. In addition to ASD occluder implantation, some patients underwent interventions of complicated malformations during the same catheterization. ASD closure procedure started under echocardiographic guidance till complicated malformations were cured. One or several devices were selected for closure of multi-fenestrated ASD based on defect diameter and distance measured by transesophageal echocardiography. In this group, all the malformations were successfully cured. Conclusion: Interventional treatment of ASD complicated with other abnormities under echocardiographic guidance is safe and effective.

DOI:
Objective: To have a acoustic densitometry(AD) analysis about the relationship between trigger intervals and effects in experimenting normal liver with high mechanical index(HMI) contrast imaging. Methods?押 Ten cases of normal liver were examined with HMI contrast imaging and the contrast agents were administrated through forearm veins at 0.3ml, trigger intervals being set at 1.0s, 2.0s, 3.0s, 4.0s respectively. The grey scale changes of imaging enhanced by contrast agents were analyzed with time-intensity cure method. The values of peak intensity(PI), area under curve(AUC), half time of descending(HT), mean transit time(MTT) were measured. Results: The time-intensity curves were almost similar at every trigger intervals, with a single-peak-shaped, looking like “a triangle”, which could be divided ascending, peak and descendent periods. but its amplitudes were different. The values of PI, AUC, HT, MTT and the effects of enhancement were gradually increased following trigger intervals increase from 1.0s to 3.0s. The values of PI, AUC, HT, MTT and the effects of enhancement were not increased any more at intervals of 4.0s and the values of PI, AUC, HT, MTT were almost similar with that measured at an interval of 3.0s, with no significant difference. Conclusion: The effects of enhancement in HMI contrast imaging can be directly influenced by trigger intervals. Following the trigger intervals increase, the effects can become stronger. But if the trigger intervals were too long, the effects increased no more.

GU Jie-hong;MO Lei;WANG Hai-lin
DOI:
Objective: To evaluate multiple spiral CT(MSCT) in the diagnosis of early renal cell carcinoma(RCC). Methods: 20 cases of early RCC in proved by pathology phases were analyzed retrospectively. Results:①In 10 patients the lesion were seen as low density, in 5 patients medium density were seen, and in 2 patients, it appeared minimal high density. Most lesions except one showed marked enhancement in cortical phase. The tumor density drops promptly in parenchymal phase, and drops further in delayed phase. ②The detection and characterization as well as accuracy of staging in 20 early RCC on MSCT were 100%, 95%, and 95%, respectively. Conclusions: ①In most patients, tumor enhancement showed characteristically the phenomenon of “quick staining and quick fainting”, which is significant in diagnosis of early RCC. ②Two-phase enhanced MSCT scan was a reliable technique in the detection, characterization and staging of early RCC. ③Multi-phase MSCT scan may increase the sensitivity, specificity and accuracy in the diagnosis of early RCC.

DOI:
Objective: To assess the clinical value of 18F-FDG PET imaging in diagnosing fever of unknown origin(FUO). Methods: Twenty-four in-patients diagnosed as FUO were enrolled in this study. They met the diagnostic criteria of FUO as fever higher than 38.3°C documented on several occasions and persisting without diagnosis for at least 3 weeks in spite of investigation for at least 1 week. Whole body 18F-FDG PET was performed in these patients. Final diagnosis was made when patients were discharged. Results: Twenty-four patients were divided into three groups according to the results of their 18F-FDG PET imaging and the final diagnosis.①18F-FDG PET imaging from 10 cases can’t provide useful information to clinical diagnosis. These included 8 cases of negative 18F-FDG PET imaging. Among them, 1 case was diagnosed as collagen disease, 1 was vascular disease, 2 cases were disease of connective tissue and another 4 cases had no final diagnosis. 2 cases had positive imaging results but without clinical specificity, including 1 case with high metabolism in bilateral hilar regions and another one with uniform hyperplasia in bone marrow. Neither of them had final diagnosis; ②four cases got useful clinical information from 18F-FDG PET imaging. These included hyper-metabolism lesions in bone marrow, detection of lymph nodes in neck and local hyper-metabolic lesions in liver. Final diagnosis were hepatic hemangioma with infection, myelodysplastic syndrome, myeloid leukemia, respectively; ③ten cases were strongly suspected as malignant diseases, including 1 case of colon leiomyosarcoma, 1 case of colon cancer and 1 case of nasopharyngeal cancer. 2 cases with multiple bone metastatic lesions with unknown origin. Five cases had remarkable F-FDG uptake in abdomen, among them, 3 cases were diagnosed as lymphoma and confirmed by pathology, 1 case was lymphadenitis and another case had inflammation of gallbladder fossa. Conclusion: 18F-FDG PET imaging can make contribution to clinical diagnosis of FUO. The sensitivity was 58.3%(14/24). Among them, malignant disease was as high as 71.4%(10/14) due to the case number of hematological malignant disease in the studied cohort.
