title: CT measurements of the anterior portions of the diaphragm with illustrative abnormal cases.
abstract: One hundred and two adult patients without evidence of diaphragmatic disease were examined by computed tomography. Patients were excluded who had evidence of neoplasma frequently associated with peritoneal implants, liver metastases, ascites, or pleural effusions. The anterior portion of the right diaphragm leaflet could be evaluated in thirteen patients and the left in 82. The normal range of diaphragm thickness was 1.2-28.6 mm on the left and 2.6-26 mm on the right. Causes for apparent increased thickness of the diaphragm leaflets are discussed and several abnormal cases illustrated.
