OBJECTIVE: Metastatic lymph node ratio (MLNR) is a known significant predictor of disease-free survival in differentiated thyroid cancer. The authors investigated the ability of preoperative fluorine-18 fluorodeoxyglucose (F-FDG) PET/CT to predict recurrence after surgery with radioactive iodine therapy considering MLNR. PATIENTS AND METHODS: A total of 274 patients who underwent preoperative PET/CT and surgery with radioactive iodine therapy were enrolled. The tumor-to-liver uptake ratio on PET/CT was calculated by dividing the maximum standardized uptake value of a primary lesion by the mean standardized uptake value of the normal liver...

Diabetic neuropathies (DNs) are nerve-damaging disorders associated with diabetes. They are commonly attributed to peripheral nerves and primarily affect the limbs of the patient. They cause altered sensitivity to external stimuli along with loss in balance and reflexes of the affected patient. DNs are associated with a variety of clinical manifestations including autonomic failure and are caused by poor management of blood sugar levels. Imaging modalities provide vital information about early physiological changes in DNs...

PURPOSE: Primary bone lymphoma (PBL) is one of the rarest primary bone malignancies. Very limited data are available on the role of fluorine-18-fluorodeoxyglucose (F-FDG) PET/CT in PBL. PATIENTS AND METHODS: Overall, 16 relevant patients had F-FDG PET/CT for staging or staging/restaging PBL. The cases with extraskeletal lesions such as lymphadenopathy or with osseous involvements in disseminated lymphoma were excluded on the basis of the definition of PBL. F-FDG PET/CT findings were correlated to pathologic and/or anatomic image information...

The administration of radionuclide therapies presents significant radiation protection challenges. The aim of this work was to develop a delivery system for intravenous radioisotope therapies to substantially moderate radiation exposures to staff and operators. A novel device (InfuShield) was designed and tested before being used clinically. The device consists of a shielded enclosure which contains the therapeutic activity and, through the hydraulic action of back-to-back syringes, allows the activity to be administered using a syringe pump external to the enclosure...
