Factors affecting the hepatobiliary excretion of 99mTc-MAG3: its clinical significance in routine renography.

Objective: Since the approval of mercaptoacetyltriglycine (MAG3) for routine clinical use, reports have appeared about hepatobiliary excretion deleteriously affecting available diagnostic and quantitative information. The purpose of this study was to evaluate gallbladder (GB) uptake of MAG3 in the clinical setting and its effect on the evaluation of relative renal function and imaging.

Methods: Sixty patients with varying degrees of renal impairment were studied.

Prospective evaluation of pain relief in 100 patients undergoing percutaneous vertebroplasty: results and follow-up.

Purpose: To determine the efficacy and durability of percutaneous vertebroplasty for the treatment of back pain associated with vertebral body compression fractures.

Materials And Methods: One hundred patients (79 women, 21 men; mean age, 73.7 y) underwent 156 percutaneous injections of polymethylmethacrylate (PMMA) into a vertebra (68 thoracic and 88 lumbar) under fluoroscopic guidance over a 35-month period.
