Comparison of MR angiography with X-ray angiography in patients with ischemic cerebrovascular diseases.

MRI angiography and x-ray conventional angiography was performed in 10 patients with ischemic cerebral diseases. In 3 patients, MRI angiography showed narrowing or occlusion of main intracranial arterial trunks, but x-ray angiography confirmed these findings only in one patient. In two other patients, narrowing or occlusion was not observed. Also, no narrowing or occlusion was observed on x-ray angiography, when MRI angiography showed normal findings. It was concluded that MRI angiography was sensitive investigation, when intracerebral occlusive disease was suspected.
