Answer

MR angiography (MRA) or transcranial Doppler ultrasonography confirm thrombotic lesions of extracranial or intracranial vessels.

Cerebral angiogram is more sensitive than CT angiogram of the brain in detecting changes of vasculitis. However, even this study often misses the predominantly small-vessel involvement of lupus vasculopathy.
