Accelerated MR image acquisition is key for emergency medicine situations, such as acute stroke, but yields degraded image quality. Therefore, our aim in this study was to calibrate a relationship between IQMs and radiologists' confidence in answering pointed clinical questions relevant to triaging of stroke patients so as to develop a protocol at low-field that is “as fast as clinically useful”. We observed that upon increasing R and decreasing NEX, radiologists’ confidence scores in their ability to identify diagnostically relevant features of both acute and chronic stroke decreased; however, radiologists’ confidence remained high despite retrospective acceleration of up to R=6.
