Alendronate-induced esophagitis: case report of a recently recognized form of severe esophagitis with esophageal stricture--radiographic features.

abstract：:Detection of pulmonary nodules using spin-echo magnetic resonance (MR) imaging was compared with detection using computed tomography (CT). Of the 25 patients studied independently by two radiologists, no lung nodules were detected in 11 (CT or MR), ten had a single nodule, and four had multiple nodules. The lesions no...
