The purpose of study was to evaluate the diagnostic value of the ZTE sequence of shoulder MRI in patients with calcific tendinitis by comparing conventional sequences. Seventy-nine patients (43 patients with calcific tendinitis and 36 control group) who underwent both radiography and MRI including ZTE sequence were enrolled in our study. Two radiologists assessed the SNR, image quality, presence, size, multiplicity, shape, margin, signal intensity, composition, and location of calcific deposits on ZTE image, FSPDWI, and T2WI. The diagnostic performance was calculated with radiography as the standard of reference. The inter-reader agreement and differentiation of the resorptive phase and formative phase on ZTE were compared to that on FSPDWI and T2WI. A total 59 calcific deposits in 43 patients were found on radiography and classified into type 1 resorptive phases (n = 20) and type 2 formative phases (n = 39). ZTE image quality was for diagnostic use with substantial inter-reader agreement. Sensitivity and detection rate of ZTE image was better than those of FSPDWI and T2WI. The inter-reader agreement of ZTE image was equal to FSPDWI and better than T2WI. The features of calcific deposits on ZTE images were significantly different between two phases. In the resorptive phase, a greater percentage of calcific deposits showed irregular shapes, ill-defined margin, heterogeneous compositions on ZTE images. In conclusion, ZTE sequence may provide useful information for the diagnosis of calcific tendinitis of the shoulder.
本研究的目的是通过比较传统序列，评估肩部MRI的ZTE序列对钙化性肌腱炎患者的诊断价值。纳入了79例接受了包括ZTE序列在内的X线摄影和MRI检查的患者（43例钙化性肌腱炎患者和36例对照组）。两名放射科医生评估了ZTE图像、FSPDWI和T2WI上钙化沉积物的信噪比、图像质量、存在情况、大小、数量、形状、边缘、信号强度、成分和位置。以X线摄影作为参考标准计算诊断性能。比较了ZTE序列与FSPDWI和T2WI序列在读者间一致性以及吸收期和形成期的鉴别能力。在X线摄影中发现43例患者共有59处钙化沉积物，并分为1型吸收期（n = 20）和2型形成期（n = 39）。ZTE图像质量可用于诊断，读者间一致性良好。ZTE图像的敏感性和检出率优于FSPDWI和T2WI。ZTE图像的读者间一致性与FSPDWI相当且优于T2WI。两个阶段ZTE图像上钙化沉积物的特征有显著差异。在吸收期，ZTE图像上更大比例的钙化沉积物表现为形状不规则、边缘不清、成分不均一。总之，ZTE序列可为肩部钙化性肌腱炎的诊断提供有用信息。
