Stroke in Pregnancy and Review of Current Literature: Arterial Spin-Labeling MRI Can Identify the Presence and Intensity of Collateral Circle.

Diagnosis and treatment of acute ischemic stroke is challenging during pregnancy. We present a diagnostic strategy in a pregnant woman with suspect of acute stroke. We perform magnetic resonance with arterial spin labeling sequence, an X-ray and contrast medium safe perfusion technique. Arterial spin labeling can detects collateral vessels in patient with acute ischemic stroke. Demonstrating collateral vessels is relevant for better understanding prognosis and for improving the diagnostic assessment in pregnancy.
