[Computed tomography in the diagnosis of pathological states of the lumbar diaphragm. 2: diseases of the diaphragm].

CT potentialities in the diagnosis of diaphragmatic diseases were considered. CT provides valuable information in relaxations of the diaphragm and diaphragmitides, permitting the detection of infiltration of the diaphragm by a tumor, retroperitoneal fibrosis, diaphragmatic cysts, Bochdalek's hernia, and hernias of the esophageal opening. An algorithm for investigation of patients with suspected diaphragmatic pathological conditions was proposed.

[Computed tomography in the diagnosis of pathological states of the lumbar diaphragm. 1: general data. Developmental defects and traumatic disorders].

CT was employed for investigation of 94 patients with pathological changes of the diaphragm. Congenital defects and unilateral aplasia of the diaphragm were observed in 5 of them. A new symptom of a pathological line of the diaphragm was recognized, characteristic for this type of patients.

[X-ray computed tomographic anatomy of the diaphragm].

The paper is concerned with retrospective analysis of CT scans of 507 patients without signs of diaphragmatic pathology to investigate normal roentgeno-anatomy of the diaphragm in CT imaging. The four main variants (types) in the structure of the lumbar diaphragm were singled out. CT was shown effective in the determination of pathological changes of the lumbar diaphragm and adjacent zones.
