DOI:
Objective: To study the relationship between the corticospinal tract(CST) injury and limb motor function by diffusion tensor imaging(DTI) in patients with cerebral infarction before and after the rehabilitation treatment, and to evaluate the application value of DTI in the assessment of clinical prognosis in patients with cerebral infarction. Methods: Twenty-three cases of chronic cerebral infarction for 23~90 days had DTI inspections respectively before and after rehabilitation. For imaging processing, fractional anisotropy(FA) encoded color maps and 3D tractography of bilateral CST of all patients were performed. The patients were divided into two group(A, B) according to the relationship between the lesions and CST, then measured FA values of the infarctions, ipsilateral cerebral peduncle and corresponding contralateral regions. The Fugl-Meyer motor scale(FM) and the Barthel index(BI) were used to evaluate the neurological function prior to each MRI. Then, the correlation between clinical markers and the changes of FA value were analyzed. Results: Before rehabilitation, FA value of the lesions in 23 cases was 0.221±0.085, and in corresponding contralateral area, the FA value was 0.514±0.071, in ipsilateral cerebral peduncle the FA value was 0.550±0.081, contralateral the FA value was 0.682±0.051. By paired t test, the FA values between bilateral brain tissues were statistically significant(P<0.001). The ratio between the FA value of ipsilateral cerebral peduncle and corresponding contralateral area of the two groups was statistically significant(t=4.066, P<0.01). Before and after rehabilitation, the reduction percent of FA value of CST in the cerebral peduncle of the two groups correlated negatively with the increase percent of FM(r=-0.624, P<0.01), but not with the percent change of BI. Conclusion: The measurement of FA values in distal infarction of CST can estimate the degree of degeneration and evaluate the recovery of motor function. The more obvious reduced of FA value, the more serious the nerve degeneration, and the worse recovery of the motor function.

DOI:
Objective: To evaluate the value of 11C-MET PET/CT and MRI for the diagnosis of gliomas before operation. Methods: We examined 11 patients prospectively with newly diagnosed gliomas based on brain MRI before operations. 11C-MET PET/CT was performed on these patients and then compared with their histological analysis. Results: Of all the eleven patients, ten were confirmed to be gliomas, except one glial cell hyperplasia. The sensitivity, specificity and accuracy of 11C-MET PET/CT and MRI for diagnosis of gliomas before operation were 100%, 100%, 100% and 100%, 0, 91%, respectively. Conclusion: 11C-MET PET/CT is more helpful than MRI for diagnosis of gliomas before operation.

WU Shan;WU Zhi-feng;E Lin-ning;JIANG Xiao-peng
DOI:
Objective: To investigate the diagnostic value of the second-generation Siemens dual-source CT(Somatom Definition Flash) dual-energy imaging of pulmonary embolism. Methods: Dual-energy pulmonary angiography(CTPA) data of 42 patients with clinically suspected pulmonary embolism were retrospectively studied by dual-energy software on the workstation. Lung PBV(lung perfusion), Lung Vessels(pulmonary vasculature) and color-coded imaging were analyzed. Two chest-imaging physicians combined information provided by both the DE-CTPA and software to make a diagnosis. Results: According to clinical and CT findings, 32 cases(76.2%, 32/42) had pulmonary embolism, with pulmonary filling defects on CTPA in 28 cases, normal CTPA but perfusion defects in sub-segments or below on DE-CTPA in four cases. Lung PBV measured 32 cases with 48 embolism pulmonary, with a CT enhancement value of (35.6±12.1) HU, lower than the non-embolism region with a CT enhancement value of (44.5±10.6) HU(t=-2.336, P=0.027). Conclusion: Dual-energy lung perfusion(Lung PBV) and pulmonary vascular(Lung Vessels) software can display perfusion defects in pulmonary embolism. Combined with CTPA, it can improve the detection rate of pulmonary embolism, especially peripheral pulmonary embolism.

XIN Jun;ZHAO Zhou-she;WU Xian-heng;QI Ru-hai;WU Wen-kai;GUO Qi-yong
DOI:
Objective: To evaluate the clinical value of dual phase 18F-FDG imaging in the diagnosis of indeterminate pulmonary nodules. Standard uptake value(SUV), rate of change of lesion volume and lesion glycolysis(LG) were analyzed and evaluated. Materials and Methods: Thirty-one cases were included in this study, all had dual phase 18F-FDG PET/CT. Scanning began after 60 min injection of 18F-FDG, was the conventional imaging, and 120 min after injection was the delayed scanning. In the patients, 25 were male and 6 were female, the average age was 57.09±13.38 years old. Twelve cases had benign pulmonary lesions(4 were granulomatous inflammatory lesion, 8 were tuberculosis), adenocarcinoma and squamous cell carcinoma in 15 cases, metastatic tumors in 4 cases. The data of SharpIR+VUE HD+TOF in all patients were selected to reconstruct PET images. GE PET VCAR tool was used to obtain maximaum SUV(SUVmax), average SUV(SUVav), volume of lesion, LG value and rate of change. Results: On dual phase 18F-FDG PET delayed imaging, the SUVmax and SUVav of granulomatous inflammatory lesion, tuberculosis, inflammation+tuberculous lesion, primary pulmonary carcinoma and metastatic tumor all had various degrees of increase. The degree of increase in SUVmax was more marked than SUVav. In inflammatory lesion the increase of SUVmax and SUVav was most obvious, that was 17.97%, and the increase in primary carcinoma was the least being 2.6%. There was either increase or decrease in volume of lesion and LG value. In tuberculosis the decrease in lesion volume was most marked that was -35.4%. The decrease of LG value in primary lung cancer was most marked, being -19.00%. Conclusion: The changes of SUVmax and SUVav in dual phase 18F-FDG PET/CT is not useful in differentiating benign and malignant pulmonary nodules. Lesion volume and LG change rate has potential capability in increasing the accurate diagnosis of indeterminate pulmonary nodules, and can be useful in the early diagnosis of primary pulmonary carcinoma.

DOI:
Objective: To study the value of using oral contrast ultrasonography(OCU), multislice computed tomography(MSCT), and the combination of the two methods in diagnosing gastric cancer. Methods: Sixty cases of gastric cancer confirmed by endoscopic biopsies and surgeries were examined by OCU and MSCT before surgery. Imaging TNM staging and postoperative pathology were compared. Results: For the total accuracy of T staging, OCU was 80.00%(48/60), MSCT was 71.67%(43/60), and their combination was 88.33%(53/60). The difference of these three methods for T staging was not statistically significant(P>0.05). However, for T1 and T2 staging, OCU(62.50%, 77.78%) was more accurate than MSCT(37.50%, 55.56%). For the total accuracy of N staging, OCU was 61.67%(37/60), MSCT was 73.33%(44/60), and their combination was 85.00%(51/60). The difference of these three methods for N staging was statistically significant(P<0.05). For the accuracy of N3 staging, OCU was 35.00%(7/20), MSCT was 75.00%(15/20), and their difference was statistically significant(P<0.05). There was no significant difference among OCU, MSCT and their combination for M staging. Conclusions: The combination of OCU and MSCT can improve the accuracy of TNM staging for gastric cancer, and have important reference value for designing surgery or treatment programs.
