Abstract

The article describes patterns of paramagnetic contrast enhanced MR tomographic imaging of atherosclerotic lesions of aorta in patients with extensive atherosclerosis and previous acute myocardial infarction.

The purpose. We have analyzed MR tomographic imaging features of atherosclerotic lesions of the aorta, with a paramagnetic contrast enhancement, in patients with extensive atherosclerosis and old acute myocardial infarction (AMI).

Materials and methods. The patients population comprised 24 patients with multiple atherosclerosis and old transmural AMI of the left ventricle. As control group eight patients with tumor pathology of the thorax were employed, without evidence of clinically significant atherosclerosis, of the same age range. All patients underwent contrast-enhanced study (paramagnetic in standard dose of 0,1 mmol / kg BW) and index of enhancement (IE) of T1-weighted images was calculated as the ratio of intensities over the aortic wall on contrast and initial MRI studies.

Results and discussion. In patients with extensive atherosclerosis and old AMI IE of the atherosclerotic lesions in the aortic wall in all cases was over 1,14 (mean 1,19±0,06), far more than increasing of intensity in the control group. Types of accumulation of contrast paramagnetic was assigned as a local or diffuse accumulation syndrome, depending on the length and circularity of the lesions. In the control group no significant accumulation of contrast paramagnetic material in the aortic wall was observed, IE did not exceed 1.04 (mean 1,01±0,02).

Conclusion. Contrast-enhanced MRI allows to visually and quantitatively assess pathology of aortic wall in atherosclerosis.
