Radiological Evaluation of Acute Ischemic Stroke
Early Diagnosis of Acute Ischemic Stroke is Critical
Goals of Imaging in Acute Stroke
Initial Stroke Imaging Should be Non-Contrast CT
Patient L’s Noncontrast CT Results
MRI vs CT for Detecting Ischemic Stroke
T1W MRI Not Useful for Imaging Acute Ichemia
Patient L’s T2 FLAIR MRI Results
T2 FLAIR MRI Superior to T1 For Imaging Ischemia
T2 FLAIR Poor at Differentiating Old vs New Ischemic Event
DWI Demonstrates New Ischemia But Not Old Infarct
DDX of Patient L’s MRI Results
Diagnosis: Acute Ischemic Stroke
MRA of Circle of Willis was Performed
Neuroanatomy Review: The Circle of Willis
