Radiological diagnosis of diseases of the large intestine

This study was undertaken to establish the most effective routine method for X-ray examination of the colon, as well as to analyze the important aspects of a detailed X-ray examination of the colon. The diagnostic values of magnification radiography and arteriography were evaluated and the possiblity of the evaluation of hemodynamics by RI angiography was discussed. The following conclusions were made: Considering the radiation dosage to the patient, routine X-ray examination of the colon should be automated, and this is possible. In a detailed X-ray examination, the delineation and evaluation of small areas bounded by innominate grooves is most important. The advantage of magnification radiography is the delineation of minute details of the mucosa and the vessels. Arteriography of the colon should be performed with a well-defined purpose and indication. (author)
