Název v původním jazyce

Ultrahigh-field MPRAGE Magnetic Resonance Angiography at 7.0 T in patients with cerebrovascular disease

Popis výsledku v původním jazyce

Objectives Time-of-flight (TOF) magnetic-resonance-angiography (MRA) identifies vessel pathology in cerebrovascular disease. At 7.0 T, the clinical performance of TOF-MRA is constrained owing to radio frequency power deposition. We studied the diagnosticvalue of whole-brain MPRAGE-based MRA as an alternative imaging technique in comparison to the clinical standard 3.0 T TOF-MRA. Methods Patients with stroke and/or moya-moya disease were included. TOF-MRA was performed at 3.0 T and MPRAGE-MRA at 7.0 T.Two radiologists rated the MRAs independently for overall quality and local arterial segment visualization. The identification of steno-occlusive pathology was reported for each protocol. Results In 18 patients (9 females; 6 patients with moya-moya) 7.0T MPRAGE-MRA provided better overall image quality and better distinction of small structures compared to 3.0 T TOF-MRA. These findings were pronounced in the proximal segments of the anterior cerebral artery (A1), middle cerebral artery
