Abstract:
Objective To evaluate the clinical value of electron beam computed tomography (EBCT)in the diagnosis of atherosclerotic aortic ulcer.Methods Sixty-eight consecutive patients(55 men and 13 women,aged 40—85 years,mean 65.12?9.55 years)with atherosclerotic aortic ulcer,who underwent EBCT scans from December 2001 to December 2004,were studied retrospectively.Contrast- enhanced continuous volume scanning(CVS)was performed by Imatron C-150XP EBCT scanner with 6 mm or 3 mm slice thickness and 100 milliseconds acquisition time.The scan was started 18—30 s after the injection of 80—100 ml contrast medium at the rate of 3.5—4.5 ml/s.Results In sixty-eight patients with atherosclerotie aortic ulcer,50 patients had acute aortic syndromes,36 had intramural hematomas,15 had atherosclerotic aortic aneurysms,3 had aortic dissections.46 patients with progresive ulcer usually had acute aortic syndrome while 22 patients with stable ulcer didn't(P
