Ultrasound versus excretory urography in evaluating acute flank pain.

abstract：:Three cases of talocalcaneal coalition were evaluated with routine radiography, conventional tomography, 99mTc-MDP bone scintigraphy, and computed tomography (CT). Routine radiography was normal in 1 case and demonstrated secondary findings suggesting coalition in 2. Conventional tomography confirmed the coalition in ...
