摘　　要：目的探讨高清弥散多次激发弥散加权成像(Resolve)序列对头颅磁共振检查(MRI)图像质量的影响。方法以本院收治行头颅检查患者80例为研究对象作回顾性研究,均接受头颅MRI及弥散加权成像(DWI)检查,DWI扫描采用单次激发平面回波(SSEPI)及Resolve序列,比较SS-EPI、Resolve序列的图像质量。结果相比于SS-EPI-DWI序列,Resolve序列所获图像质量主观指标中伪影、图像变形程度、病灶清晰度、病灶周围结构清晰及总体得分均更高(P<0.05);与SS-EPI-DWI序列相比,除ADC外,Resolve序列所获图像质量客观指标中SNR、RR及CR均更高(P<0.05)。结论在头颅磁共振检查中,应用高清弥散Resolve序列进行DWI检查所获图像质量较好,具有较佳临床应用价值。Objective To investigate the effect of high-resolution diffusion multiple excitation diffusion weighted imaging(Resolve)sequence on the image quality of skull magnetic resonance imaging(MRI).Methods A retrospective study was conducted on 80 patients who underwent head examination in our hospital.All of them were examined by head MRI and diffuse-weighted imaging(DWI).The DWI scans were performed using single excitation plane echo(SS-EPI)and Resolve sequence,and the image quality of SS-EPI and Resolve sequences was compared.Results Compared with SS-EPI-DWI sequence,artifacts,degree of deformation,focus clarity,clarity of surrounding structures and overall scores of Resolve sequence were higher(P<0.05).Compared with SS-EPI-DWI sequence,SNR,RR and CR of Resolve sequence were higher than those of ADC(P<0.05).Conclusion The quality of the image obtained by DWI with high-resolution Resolve sequence is good and has good clinical application value.
