Increased skeletal:renal uptake ratio: etiology and characteristics
Abstract:
Twenty-four patients with increased skeletal:renal uptake ratios of 99mTc-methylene diphosphonate were studied. Increased uptake was central in metastatic prostate carcinoma, peripheral in hematologic disorders, and heterogeneous in Paget disease and fibrous dysplasia. There was no discernible redistribution of skeletal uptake in patients with renal failure. Absence of both renal and bladder activity was not observed in patients with normal renal function. An increased ratio was always abnormal and frequently indicated diffuse bone disease.

Renal Drug Excretion: Overview
A nephron consists of two primary structures: the renal corpuscle and the renal tubule. The renal corpuscle contains the glomerulus, a network of capillaries where the first step of renal excretion, glomerular filtration, occurs. Blood pressure forces water, ions, and small molecules out...
