Comparing ovarian radiation doses in flat-panel and conventional angiography during uterine artery embolization: a randomized clinical trial.

Background: Uterine artery embolization (UAE) is a minimally invasive procedure performed under fluoroscopy for the treatment of uterine fibroids and accompanied by radiation exposure.

Objectives: To compare ovarian radiation doses during uterine artery embolization (UAE) in patients using conventional digital subtraction angiography (DSA) with those using digital flat-panel technology.

Patients And Methods: Thirty women who were candidates for UAE were randomly enrolled for one of the two angiographic systems.

Improvement of MR cholangiopancreatography (MRCP) images after black tea consumption.

Objective: Evaluation of the efficacy of black tea as the negative oral contrast agent in MRCP.

Materials And Methods: MRCP was performed before and 5 and 15 min after tea consumption for 35 patients. Depiction of the gall bladder (GB), cystic duct (CD), proximal and distal parts of the common bile duct (CBD), intrahepatic ducts (IHD), ampulla of vater (AV), main pancreatic duct (MPD) and signal loss of stomach and three different segments of the duodenum were investigated according to VAS and Likert scores.
