摘　　要：目的探讨智能快速磁共振技术(intelligent quick magnetic resonance,IQMR)在冈上肌肌腱损伤中的应用价值。材料与方法对40例冈上肌肌腱损伤患者行肩关节冠状位快速T2WI脂肪抑制(T2WI fat saturation,T2WI-FS)和常规T2WI-FS序列扫描,将快速T2WI-FS序列的图像传入IQMR后处理系统,自动生成T2WI-FS_(IQMR)图像。由两位放射科医师各自独立对T2WI-FS_(快速)、T2WI-FS_(常规)和T2WI-FS_(IQMR)序列的三组图像的病灶细节清晰度、解剖结构清晰度、整体图像伪影和整体图像质量进行定性评分;根据Zlatkin分型对三组图像的冈上肌肌腱损伤程度进行分级评估,并测量比较三组图像的冈上肌、肱骨头和三角肌的信噪比(signal to noise ratio,SNR)、冈上肌与肱骨头的对比噪声比(contrast to noise ratio,CNR1)和三角肌与肱骨头的对比噪声比(CNR2)。结果T2WI-FS_(IQMR)序列较T2WI-FS_(常规)序列的扫描时间缩短了41%。定性分析:T2WI-FS_(IQMR)图像在病灶细节清晰度、解剖结构清晰度、整体图像伪影和整体图像质量方面的评分均优于T2WI-FS_(快速)和T2WI-FS_(常规)序列图像(P<0.001);三组图像在诊断冈上肌肌腱损伤程度分级上差异无统计学意义(P>0.05)。定量分析:T2WI-FS_(IQMR)组图像的冈上肌、肱骨头和三角肌的SNR、冈上肌与肱骨头的CNR1和三角肌与肱骨头的CNR2均大于T2WI-FS_(快速)组和T2WI-FS_(常规)组(P<0.001)。结论在冈上肌肌腱损伤MRI扫描中,IQMR技术可以明显缩短扫描时间,提高图像质量,值得临床推广应用。Objective:To explore the application value of Intelligent Quick Magnetic Resonance(IQMR)in the supraspinatus tendon injury.Materials and Methods:40 patients with supraspinatus tendon injuries underwent coronal fast T2WI fat saturation(T2WI-FS)and conventional T2WI-FS sequences scanning of the shoulder,the images of fast T2WI-FS sequence were transferred to IQMR post-processing system to generate T2WI-FS_(IQMR)images automatically.Three groups of MRI images were independently scored by two radiologists for the clarity of lesion detail,the clarity of anatomical structure,overall image artifacts and overall image quality.The degree of supraspinatus tendon injury of three groups of MRI images were independently graded by two radiologists according to Zlatkin classification.The signal-to-noise ratio(SNR)of the supraspinatus,humeral head,and deltoid muscles,contrast noise ratio(CNR1)of the supraspinatus muscle to the humeral head,and contrast noise ratio(CNR2)of deltoid muscle to the humeral head were measured and compared among the three groups of MRI images.Results:The scanning time of T2WI-FS_(IQMR)sequence was 41%shorter than that of conventional T2WI-FS sequence.Qualitative analysis:The image quality scores of T2WI-FS_(IQMR)were higher than those of fast T2WI-FS and conventional T2WI-FS in terms of the clarity of lesion detail,the clarity of anatomical structure,overall image artifacts and overall image quality(P<0.001).There was no significant difference among the three groups in the diagnosis of supraspinatus tendon injury(P>0.05).Quantitative analysis:SNR of the supraspinatus,humeral head and deltoid,CNR1 and CNR2 of T2WI-FS_(IQMR)were higher than those of fast T2WI-FS and conventional T2WI-FS(P<0.001).Conclusions:In the supraspinatus tendon injury MRI scanning,IQMR technology can significantly reduce the scanning time and improve image quality,which is worthy of clinical application.
