The Value of High Resolution Vessel Wall Magnetic Resonance Imaging in the Etiological Diagnosis of Ischemic Stroke

Objective To evaluate the value of high resolution vessel wall MRI in the etiological diagnosis of
ischemic stroke.
Methods The clinical and imaging data of patients with acute ischemic stroke who were admitted
to our hospital within 2 weeks of onset from May 2014 to May 2019 and had completed HRMRI
scan of culprit vessel or the parent artery of culprit vessel during hospitalization were
retrospectively analyzed. The etiological diagnosis was made before and after HR-MRI scan in all
the patients, according to the CISS criteria. The value of HR-MRI in the etiological diagnosis of
ischemic stroke was analyzed.
Results A total of 139 patients were included. The etiological diagnosis profile before HR-MRI scan:
89 cases with large artery atherosclerosis (LAA) subtype, 45 cases with penetrating artery disease
(PAD) subtype, 3 cases with other etiology (OE) subtype and 2 cases with undetermined etiology (UE)
subtype. The etiological diagnosis profile after HR-MRI scan: 108 cases with LAA subtype, 27 cases
with PAD subtype, and 4 cases with OE subtype. Though HR-MRI scan, 18 cases with the initial
diagnosis of PAD subtype and 1 case with the initial diagnosis of OE subtype were finally diagnosed
with LAA subtype, and 2 cases with the initial diagnosis of UE subtype were finally diagnosed with
OE subtype, so the final diagnosis of 21 cases (15.11%) was modified through HR-MRI.
Conclusions HR-MRI can clearly show the structure of intracranial vessel wall, which is helpful
for clinicians to make accurate diagnosis and treatment for stroke patients.
