Lower extremity scintigraphy: the foot and ankle.

Disorders of the ankle and foot are common and may pose a significant clinical problem. Acute injuries of the ankle and foot are routinely evaluated by radiographs and, if inconclusive, by magnetic resonance imaging (MRI) or computed tomagraphy (CT). In subacute or chronic injuries, where prolonged pain is unexplained, bone scintigraphy may play a significant role.

Quantitative SPECT of technetium-99m-DMSA uptake in the kidneys of normal children and in kidneys with vesicoureteral reflux: detection of unilateral kidney disease.

Unlabelled: Quantitative SPECT was used to evaluate renal functional volume (cc), percent of injected dose/cc (%ID/cc) and renal uptake (%) in 11 children with unilateral vesicoureteral reflux grade 3 or greater, and in 19 normal control children without reflux.

Methods: Studies were performed 4-6 hr after intravenous injection of 0.750-2 mCi of 99mTc-DMSA.
