Diagnostic Performances of PETRA-MRA, TOF-MRA, and CTA in Assessing Intracranial Arterial Stenosis with DSA as a Reference Standard
View through CrossRef
This study compared the performance of three noninvasive techniques, namely, 3D pointwise encoding time reduction magnetic resonance angiography (PETRA-MRA), 3D time-of-flight (TOF) MRA and computed tomography angiography (CTA) in accurately measuring the degree of stenosis and lesion length in patients with intracranial arterial stenosis using DSA as the reference standard. This study demonstrated that the estimation of intracranial stenosis and lesion length by PETRA-MRA was more accurate and comparable with DSA than TOF-MRA and CTA. Therefore, PETRA-MRA is a promising noninvasive tool for the accurate assessment of ICAS.
