摘　　要：目的比较自适应图像接收(AIR)线圈与腹部相控阵(AA)线圈在中分化直肠腺癌快速自旋回波(FSE)T2WI序列成像中的应用效果,为临床提供更有效的检查方法。方法回顾性分析术前行MRI检查且病理确诊为直肠中分化腺癌的90例患者,随机分成A、B两组,每组45例,分别应用AIR及AA线圈进行检查,比较两组快速自旋回波(FSE)T2WI序列的直肠癌病变及坐骨直肠窝处脂肪的客观图像质量与主观图像质量,客观图像质量通过观测图像的信噪比(SNR)评估,主观图像质量通过图像质量评分进行评估。结果A组直肠癌及坐骨直肠窝处脂肪图像的SNR及主观图像质量评分较B组均更高(P<0.05)。结论AIR线圈具有更高的信噪比和图像质量,病变的显示能力更强,能为直肠病变MRI检查提供更有利的支持。Objective To compare the application effects of adaptive image receiving(AIR)coil and anterior array(AA)coil in fast spin echo(FSE)T2-weighted imaging of medium differentiated rectal adenocarcinoma,and providing a more effective method for clinical examination.Methods A retrospective analysis was performed on 90 patients who were examined by MRI and were pathologically diagnosed as medium differentiated rectal adenocarcinoma before operation,and they were randomly divided into group A and group B,45 cases in each group.The two groups were examined with adaptive image receiving(AIR)and anterior array(AA)coils respectively,objective and subjective image quality of rectal cancer lesions and fat of ischiorectal fossa were compared between the two groups on fast spin echo(FSE)T2WI sequences,the objective image quality was evaluated by observing signal-to-noise ratio(SNR)of rectal cancer and the subjective image quality was evaluated by image quality score.Results The SNR and subjective image quality scores which are measured in the rectal cancer and fat of ischiorectal fossa images in group A were higher than those in group B(P<0.05).Conclusion AIR coil has higher SNR and image quality,and better lesion display ability,and can provide more favorable support for MRI examination of rectal lesions.
