高频超声在冈上肌钙化性肌腱炎中的诊断效果研究

Diagnostic value of high-frequency color Doppler for calcific tendinitis of supraspinatus muscle

目的:探讨高频彩色超声在冈上肌钙化性肌腱炎中的诊断价值,为临床早期诊断冈上肌钙化性肌腱炎提供依据。方法:采用高频彩色超声和磁共振成像(magnetic resonance imaging,MRI)对55例冈上肌钙化性肌腱炎患者的患侧和健侧进行检查,比较2组检查方法的图像效果、灵敏度、特异度及准确度等。结果:超声图像显示,单发型钙化有15例(31.3%),多发型钙化33例(68.8%)。超声检查钙化性肌腱炎的灵敏度、特异度、准确度分别为91.7%、81.3%、86.5%,与MRI检查的灵敏度(94.0%)、特异度(86.0%)、准确度(90.0%)比较无统计学差异(P>0.05)。结论:高频彩色超声检查冈上肌钙化性肌腱炎具有较高的灵敏度、特异度和准确度,诊断效果与MRI相近,但价格便宜,可作为冈上肌钙化性肌腱炎检查的首选影像学方法。

Objective To explore the diagnostic value of high-frequency color Doppler for calcific tendinitis of supraspinatus muscle to facilitate its early diagnosis. Methods High-frequency color Doppler and MRI were used to examine the affected and unaffected sides of 55 patients with calcific tendinitis of supraspinatus muscle, and then the imaging effects, sensibilities, specificities and accuracies were compared for the examination methods. Results Color Doppler showed that there were 15 patients with solitary calcification（31.3%） and 33 ones with multiple calcification（68.8%）. The sensibility, specificity and accuracy of color Doppler were 91.7%, 81.3% and 86.5% respectively, while the ones of MRI were 94.0%, 86.0% and 90.0% respectively. There were no significant differences between the sensibilities, specificities and accuracies of the two methods, with P〉0.05. Conclusion High-frequency color Doppler gains higher sensitivity,specificity and accuracy while lower cost when compared with MRI, and thus can be used as the preferred choice for the diagnosis of calcific tendinitis of supraspinatus muscle.
