Objective: The aim of this study was to evaluate the value of interictal 18F-FDG and 13N-NH3·H2O PET imaging in localizing the epileptic foci in patients with mesial temporal lobe epilepsy(MTLE). Methods: Preoperative MRI, 18F-FDG and 13N-NH3·H2O PET data in 17 MTLE patients confirmed by electrocorticogram(ECoG) and depth electroencephalogram(DEEG) were retrospectively analysed. The PET images were visually assessed with ROI-based analysis. The 18F-FDG and 13N-NH3·H2O PET images were compared. Results: According to the ROI-based analysis, the FDG uptake and the CBF(cerebral blood flow) correctly determined the side of the epileptic temporal lobe in twelve cases(70.6%) and nine cases(52.9%) respectively, correctly determined the side of the epileptic focus on the mesial temporal structure in five cases(29.4%) and four cases(23.5%), respectively. The diagnostic performance of the two agents were in moderate concordance by Kappa test(Kappa=0.638, P=0.005). And there was no statistically significant difference in the localization accuracy between the two agents. FDG uptake combined CBF correctly determined the side of the epileptic focus on the mesial temporal structure in eight cases(47.1％). Conclusion: Positron emission tomography measurement of FDG uptake was most sensitive in detecting the side of the epileptic temporal lobe, CBF PET also can lateralize the epileptic temporal lobe effectively. When combine FDG uptake with CBF imaging, the specificity may be improved.

DOI:
Objective: To analyze the radiological features of esophageal inlet lesions by CT and barium study in order to improve the diagnostic accuracy. Methods: The clinical and radiological data of 34 cases with esophageal inlet lesions were retrospectively analyzed. All cases were pathologically confirmed by surgery or biopsy. Twenty-seven patients underwent CT scan with contrast and 7 patients underwent plain CT scan. Twenty-eight patients underwent barium study. Results: Surgery or biopsy revealed 14 cases with primary esophageal tumor(12 cases of squamous carcinoma and 2 cases of undifferentiated cancer), 3 cases were hypertrophy of sphincter, 5 cases were diverticulum, 12 cases were due to trauma. All patients presented with dysphagia. In cases with late stage esophageal cancer, barium study showed mucosa destruction. CT scan may have negative findings in patients with early stage cancer while irregular thickening of esophagus or intra-luminal mass can be found in patients of late stage. In cases of hypertrophy of esophageal sphincter, CT scan showed localized wall thickening of esophagus with smooth mucosa. In cases of esophageal diverticulum, CT scan revealed unenhanced mass of esophageal inlet. Barium study showed niche filling with contrast. In patients with esophageal perforation, barium study showed contrast dissemination into cervical soft tissue. In 2 cases of esophageal perforation with superior mediastinal abscess, CT scan showed low density lesion with typical ring-like enhancement. Conclusion: Concerning low-cost, convenience and easy-to-perform, barium study remains irreplaceable in diagnosis of esophageal inlet lesions. CT is significant in staging of esophageal tumor and evaluation of esophageal trauma and its complications. Combining both methods can improve the diagnostic accuracy of esophageal inlet lesions.

DOI:
Objective: The pathohistology of retroperitoneal neurogenic tumor is multiplex, by the analysis of the tumor’s ultrasonography, we try to discriminate the benign tumor from the malignant tumor and evaluate the ultrasonographic imaging features of retroperitoneal neurogenic tumor. Methods: The ultrasonographic imaging features of 25 cases were analyzed and compared with the results of pathology. Results: The common sites of retroperitoneal neurogenic tumor included spinal roots and the area surrounding kidney and adrenal; The tumors were large, mainly hypoechoic. Thirteen cases were cystic, 13 cases had calcification; No difference between the benign and malignant tumors on the shape and boundary(P>0.05); No difference between the benign and malignant tumors on the color Doppler flow imaging(CDFI)(P>0.05); The diameter of the malignant tumor was much larger than that of the benign tumor(P<0.025, a=0.05). Close and tiny calcification was the characteristic of the neuroblastoma, the CDFI of pheochromocytoma was plentiful, associated with dispersed small cysts and there were its characteristics. Conclusions: The ultrasonograhic features of retroperitoneal neurogenic tumor is not characteristic and ultrasonograhic accuracy was not high; It is not reliable to distinguish the benign and malignant tumors by the shape, boundary or CDFI only.
