F-FDG PET/CT for predicting inferior vena cava wall invasion in patients of renal cell carcinoma with the presence of inferior vena cava tumor thrombus.

Introduction: Preoperative evaluation of inferior vena cava (IVC) wall invasion is very important to improve outcomes of patients with renal cell carcinoma (RCC), and may allow surgical urologists to treat the IVC more effectively. The objective of this study was to evaluate preoperative F-FDG PET/CT in patients with RCC and IVC tumor thrombus (IVCTT) for the diagnosis of IVC wall invasion.

Methods: This retrospective case-control study evaluated 68 patients with RCC with level I-IV tumor thrombus.

Solitary Periaortic Tuberculous Granuloma Mimicking Neoplastic Disease on 18 F-FDG PET/CT.

Solitary tuberculoma of periaortic space is extremely rare. We report a case of periaortic tuberculous granuloma revealed by 18 F-FDG PET/CT in a 51-year-old woman without pulmonary or any other organ involvement. Awareness of this rare but possible atypical presentation of tuberculosis is helpful for the differential diagnosis of periaortic mass.

Diagnostic value of F-FDG PET/CT versus contrast-enhanced MRI for venous tumour thrombus and venous bland thrombus in renal cell carcinoma.

The purpose of this study was to compare the ability of F-FDG PET/CT and contrast-enhanced MRI (CEMRI) to detect and grade venous tumour thrombus (VTT) and venous bland thrombus (VBT) in RCC and assess invasion of the venous wall by VTT. The PET/CT and CEMRI data of 41 patients with RCC were retrieved. The difference in maximum standardized uptake value (SUVmax) between VTT and VBT was analysed.

Correlation of abdominal fat distribution with different types of diabetes in a Chinese population.

To investigate abdominal fat distribution in Chinese subjects with diabetes and its correlation with different types of diabetes. A total of 176 diabetic subjects were enrolled, 92 with type 1 and 84 with type 2, with a mean age of 27.41 and 49.
