摘　　要：目的:探讨深度学习(DL)算法在改善前列腺快速自旋回波(TSE)T_(2)WI序列图像质量和加快扫描速度中的应用价值。方法:前瞻性收集54例前列腺疾病患者,均行前列腺常规T_(2)WI序列和联合DL的T_(2)WI(T_(2)WI_(DL))序列扫描。对2组图像质量进行定性、定量评估,定性评估包括:伪影、前列腺包膜清晰度、病灶的细节清晰度和整体图像质量;定量评估包括:以前列腺病灶和髂腰肌为ROI,测量并比较2组图像病灶SNR,以及病灶与髂腰肌的CNR。结果:T_(2)WI_(DL)序列在伪影、前列腺包膜清晰度、病灶的细节清晰度和整体图像质量的评分均优于常规T_(2)WI序列(均P<0.001)。T_(2)WI_(DL)序列图像的SNR_(病灶)和CNR_(病灶/肌肉)均优于常规T_(2)WI序列(均P<0.05)。结论:与常规T2WI序列相比,T_(2)WI_(DL)序列可提高图像质量,且扫描时间减少了96 s(约47%),在前列腺疾病的临床应用中有较大潜力。Objective:To explore the application value of deep learning(DL)algorithm in improving the image quality of the prostate TSE-T_(2)WI sequence and reducing scanning time.Methods:54 patients with prostate lesions were prospectively collected for prostate conventional T_(2)WI and DL-assisted T_(2)WI(T_(2)WI_(DL))scans.The image quality of two groups was evaluated qualitatively and quantitatively.The artifact,the clarity of the prostate envelope,detail clarity of the lesion and overall image quality were qualitatively assessed.The prostate lesions and iliopsoas were chosen as ROIs,the lesion SNR and CNR between lesions and iliopsoas of the 2 groups were measured and compared.Results:T_(2)WI_(DL)was superior to conventional T_(2)WI in the scores of artifact,clarity of the prostate envelope,detail clarity of the lesion and overall image quality(all P<0.001).All the lesion SNR and CNR of T_(2)WI_(DL)sequence were better than those of conventional T_(2)WI sequence(both P<0.05).Conclusions:Compared with conventional T_(2)WI sequence,T_(2)WI_(DL)sequence can improve image quality and reduce scanning time by 96 s,which has great potential for clinical application in prostate diseases.
