[Abstract] Objective To explore the application value of multiple parametric (MTP) synthetic sequence in acute ischemic stroke.Materials and Methods A prospective study was conducted on 51 patients with acute ischemic stroke. Conventional sequence and MTP synthetic sequence were scanned respectively. The differences in overall image quality, image signal-to-noise ratio (SNR) and lesion detection efficiency were compared.Results In terms of subjective score of overall image quality, compared with conventional sequence, MTP synthetic sequence has no statistical significance in T1WI and susceptibility weighted imaging (SWI) sequence (Z=-1.89, -0.45; P=0.06, 0.66), and has statistical significance in T2WI and T2WI-fluid attenuated inversion recovery (T2WI-FLAIR) sequence (Z=-3.64, -4.16; P<0.001). The image quality of conventional sequence is better than MTP synthetic sequence. In terms of image brain tissue SNR, MTP synthetic sequence was superior to conventional sequence in brain tissue SNR of T1WI, proton density weighted image (PDWI), T2WI-FLAIR and SWI (Z=-4.78; P<0.001). There was no statistical significance between MTP synthetic sequence and conventional sequence in the display efficiency of cerebral infarction lesions and the detection rate of microbleeding lesions (χ2=0.54, 0.16; P=0.77, 0.92).Conclusions The application of MTP synthetic sequence can shorten the examination time of patients and obtain routine and quantitative MRI images. It has good clinical application value for the imaging diagnosis of acute ischemic stroke.
