A reduced physiological F-fluorodeoxyglucose uptake in the brain and liver caused by malignant lymphoma being deprived of the tracer.

Purpose : To investigate whether or not the physiological brain and liver FDG uptake are decreased in patients with highly accelerated glycolysis lesions. Methods : We retrospectively analyzed 51 patients with malignant lymphoma. We compared the FDG uptake in the brain and liver of the patients with that in a control group.

Ultraselective transcatheter arterial embolization with small-sized microcoils for acute lower gastrointestinal bleeding.

Purpose: To evaluate the clinical outcome of ultraselective transcatheter arterial embolization (TAE) with small-sized microcoils for acute lower gastrointestinal bleeding (LGIB).

Materials And Methods: The subjects were 17 consecutive patients (mean age, 69 years) with LGIB who were treated with ultraselective TAE using small-sized microcoils between December 2013 and December 2019. Ultraselective TAE was defined as embolization of one or both of the long or short branches of the vasa recta.
