Key result
A rapid 3 Tesla MRI protocol including a novel chest MRA sequence successfully detected acute type A aortic dissection in two patients presenting with acute ischemic stroke symptoms.
Why the study?
Preoperative screening for acute ischemic stroke must be rapid before thrombectomy, yet differentiating aortic dissection causing neurological symptoms is critical for safe treatment.
Case Report (n=2)
No
A short 3T MRI protocol including chest MRA can rapidly and safely detect painless acute type A aortic dissection in patients presenting with acute ischemic stroke symptoms, preventing catastrophic outcomes from inappropriate thrombolysis.
May support avoiding thrombolysis in select stroke patients; hypothesis-generating case report requiring prospective validation.

Oura et al. (2019) conducted a case report in Suspected acute ischemic stroke / Acute type A aortic dissection (n=2). 3 Tesla MRI protocol with chest screening MRA (simple T1-TFE) was evaluated on Detection of acute type A aortic dissection. A rapid 3 Tesla MRI protocol including a novel chest MRA sequence successfully detected acute type A aortic dissection in two patients presenting with acute ischemic stroke symptoms.
