MR 1.0 T in diagnostic of cerebrovascular disease (Correlation of Colour Doppler, CT AND MR findings)

The aim was to compare US, CT and MR findings of cerebtovascular disease, particularly of its entities. The data on 20 patients (MIF 13/7) with the clinical history of transitory ischaemic attacks (TIA) or stroke were evaluated. Ten patients had TIA and ten CV stroke. The personal history was taken, clinical examinations and laboratory tests done, and followed by carotid and vertebral Colour Doppler Brain CT was done 24 to 48 hours afler the clinical manifestation of TIA or stroke. MR (1.0 T) was done 3 to 9 days afier the beginning of the disease. Colour Doppler showed subtotal intemal carotid artery stenosis in 14 patients, and vertebral artery occlusion in 6 patients. CT findings did not show isehaemic infarction lesions in 9 patients. Six patients had ischaemic infarction lesions and 5 patients had multiple white matter isehaemic lesions. MR showed ischaemic lesions in all patients: ishemic infarct lesions in l2 patients, white matter changes in 5, and lacune in 5 patients. Two patients had both ischaemic lesions and lacune. In several cases MR-angiography was done. CONCLUSION: Advantages of MRI over CT in t.he diagnosing cerebrovascular disease are in the fact that edematous changes in the region of the recent infarction can be detected much earlier on MR images. MR provides a better insight into the zones of petechial bleeding of infarction region in a subacute stage.
