ABSTRACT

The results of computed tomography (CT) was compared with ultrasonographic and angiographic findings in 168 patients. All data of radiation diagnosis of abdominal aortic aneurysms (AAA) were compared with those of operations and morphological studies of the resected fragments of the aortic parts changed due to aneurysms. These comparisons provided a detailed characterization of the potentialities of CT performed on a third-generation unit in the presurgical diagnosis of this abnormality. At the same time, detailed XCT findings (semeiotics of AAA and their complications, such infiltration, dissection, and rupture) are given. The study shows benefits of the refined AAA by applying routine CT. The paper gives a diagnostic algorithm of using radiation studies (ultrasonography, CT, angiography) in the diagnosis of AAA. Third-generation CT units widely used in clinical practice are shown to provide necessary and complete information on the magnitude of AAA. This makes it possible to extend the capacities of timely detection of this abnormality and to make a successful surgical intervention.
