Differential diagnosis of acute and chronic pulmonary thromboembolism according to MSCT data

Introduction . One of the important problems medical imaging is differential diagnosis patients with acute and chronic pulmonary embolism. The widely used minimally invasive technique multispiral computed tomography intravenous bolus contrast enhancement can serve to solve this problem, in particular, assess state parenchyma vascular structures lungs. purpose To bronchial arteries parenchymal changes lungs thromboembolism based on results their role more precise disease. Materials methods An analysis CT-angiopulmonography 600 suspected PE was performed. 87 confirmed were selected divided into groups according final diagnosis: group 1 — embolism, 2 CT data analyzed for presence pathologically changed arteries, as well lung's (including mosaic perfusion, fibrotic changes, dilatation or without wall thickening). Results Bronchial assessed embolism diagnostic value detected determined. Acute does not lead such In diagnostically unclear cases, secondary signs visible (mosaic perfusion dilated bronchi thickening) be useful Conclusions Most demonstrated Lung's (a pattern dilation common These CT-signs help differentiate from clinical situations.
