Application of MAGnetic resonance imaging compilation in acute ischemic stroke

Figure 1 A 61-year-old man with transient ischemic attack. Automatic image reconstruction from MAGnetic resonance imaging compilation (MAGiC) raw data. A: MAGiC T2-fluid-attenuated inversion recovery (left); B: MAGiC T2 mapping (middle); C: MAGiC phase sensitive inversion recovery Vessel (right).

Figure 2 A 49-year-old man with bilateral lacunar cerebral infarction. A: Three-dimensional time-of-flight magnetic resonance angiography (left); B: MAGnetic resonance imaging compilation phase sensitive inversion recovery Vessel (middle); C: Computed tomography angiography (right). All three examination methods showed severe local stenosis of the left middle cerebral artery (arrows).

Figure 3 A 53-year-old man with right cerebral infarction. A: The right middle cerebral artery was not shown in three-dimensional time-of-flight magnetic resonance angiography (left); B: MAGnetic resonance imaging compilation phase sensitive inversion recovery Vessel (middle); and C: Computed tomography angiography (right). Both the latter two showed mild and moderate stenosis of the local lumen of the right middle cerebral artery (arrows).

Figure 4 Bland-Altman and receiver operating characteristic curve evaluation of vascular stenosis degrees obtained by MAGnetic resonance imaging compilation phase-sensitive inversion recovery Vessel and time-of-flight magnetic resonance angiography. A: MAGnetic resonance imaging compilation-computed tomography angiography; B: Time-of-flight magnetic resonance angiography; C: Receiver operating characteristic curves. TOF: Time-of-flight; CTA: Computed tomography angiography; ROC: Receiver operating characteristic.
