Evaluation of the blood supply and efficacy of transcatheter arterial chemoembolization for patients with liver metastasis using F-fluorodeoxyglucose positron emission tomography/computed tomography.

Our study aims to evaluate the efficacy of transcatheter arterial chemoembolization in the treatment of patients with liver metastasis using integrated F-fluorodeoxyglucose positron emission tomography/computed tomography. A total of 97 liver metastasis patients treated by transcatheter arterial chemoembolization were enrolled in this study. The F-fluorodeoxyglucose positron emission tomography/computed tomography images of liver metastasis patients were collected before and after transcatheter arterial chemoembolization treatment.

[Spiral computed tomography images of extraluminal type gastric stromal tumors].

Objective: To evaluate the diagnostic value of spiral CT and its reconstruction techniques in the diagnosis of extraluminal type gastric stromal tumors.

Methods: The data of spiral CT performed 1 week before operation of 17 extraluminal type cases, 11 males and 6 females, aged 35.5 (13-67), from 33 patients of gastric stromal tumors proved by pathology and immunohistochemistry, were analyzed retrospectively.
