Objectives Assessment of the diagnostic usefulness of MRA in evaluation of patients with
acute intra cranial steno-occlusive arterial disease. Patients and methods 84 patients with
acute intracranial steno-occlusive arterial disease were subjected to the following brain MRI
protocol: Axials DWI, T1WI, T2WI, FLAIR, T2∗ Gradient Echo Imaging and 3D TOF MRA.
Results Eighty four patients (M/F= 49/35) aged between 28 and 86 years. MRA findings of
arterial segments correlated with location of the ischemic lesions described by different MRI
sequences including the DWI in all cases (100%). MRA of the intracranial vessels revealed
60 arterial segments with occlusions/absent flow. Occlusions were most common in MCAs
(n= 45) followed by PCAs (n= 9). 31 arterial segments with stenosis were seen, and they
were mainly affecting arterial territories of PCAs (n= 16). Atheromatous plaques were …
