Numerous pathologic conditions may affect the diaphragm. Precise localization and characterization of these lesions may at times be difficult due to the shape and complex anatomic relationships of the diaphragm. Chest radiography is a useful screening tool for diaphragmatic abnormalities. Cross-sectional imaging including ultrasound, spiral CT with multiplaner reformation images, magnetic resonance imaging (MRI) can depict intrinsic pathology of the diaphragm and can assist in the evaluation of peridiaphragmatic masses by depicting the underlying complex anatomic relationship. Fluoroscopy is a useful additional study to evaluate the diaphragmatic motion, although ultrasound and MRI also are capable of this function. Knowledge of normal anatomy and various pathologic condition of the diaphragm and selection of the most appropriate imaging technique can greatly facilitate the diagnosis of diaphragmatic abnormalities.
