Bone SPECT/CT in Advanced Diffuse Tenosynovial Giant Cell Tumor of the Wrist.

Tenosynovial giant cell tumor, previously known as pigmented villonodular synovitis, is a benign low-grade fibrohistiocytic proliferation with hemosiderin deposits in synovial joints. Mostly affecting the knee, it can also manifest in other synovial joints, infrequently also in the wrist. Tenosynovial giant cell tumor typically causes intense radionuclide uptake in all phases in planar bone scintigraphy, making a differentiation from other bone tumors or osteomyelitis difficult, especially in cases associated with extensive bone destruction.

Yttrium-90 radioembolization of unresectable hepatocellular carcinoma - a single center experience.

Purpose: To determine the value of radioembolization (RE) for treatment of unresectable hepatocellular carcinoma (HCC).

Patients And Methods: Records of patients undergoing RE for unresectable HCC were retrospectively reviewed. Biochemical and clinical toxicities, imaging response (according to modified Response Evaluation Criteria In Solid Tumors), time-to-progression (TTP) and overall survival (OS) were analyzed.
