【摘要】 目的 探讨3.0T MR足踝线圈在跟腱检查中的应用及对图像质量的影响。方法 因跟腱症状行MR检查的患者26例,志愿者5例。扫描序列包括T₁WI、PDWI、T₂WI脂肪抑制及STIR,对照分析患者的影像诊断和临床资料,对患者的图像质量进行主观评分,评价志愿者跟腱检查的舒适度。结果 跟腱损伤10例,跟腱炎6例,跟腱部分断裂3例,腱黄瘤1例,跟腱信号及形态正常6例。图像评分显示T₁WI、PDWI及T₂WI脂肪抑制图像评分较高,对跟腱的解剖结构及病变显示清晰,STIR序列图像的评分较低。足跟处图像变形,组织层次消失,局部信号增高。志愿者对线圈入口处及足跟支撑点感觉稍有不适。结论 3.0T MR使用足踝线圈进行跟腱检查图像质量较好,线圈的整体舒适度较高。更多还原

【Abstract】 Objective To explore the image quality of 3.0 T Magnetic Resonance foot and ankle array coil on Achilles tendon abnormalities for the clinical application.Methods 26 patients（with Achilles tendon symptoms）and 5 volunteers underwent MR examination.The scanning sequences were used:T₁WI、PDWI、T₂WI-FS and STIR.Image diagnoses and clinical data of all patients were obtained and analyzed.Subjective scores on image quality were used.Degrees of comfort in coil were evaluated.Results 10 patients had A chilles tendon injury,6 patients with Achilles tendonitis,3 patients with part Achilles tendon rupture,1 patient with tendon xanthoma,and 6 patients were normal.Image scores in patients with T₁ WI、PDWI and T₂WI-FS sequences were higher,the anatomic structures,lesions of whole Achilles tendon were clear.On the contrary,the lower scores were in STIR sequences.In the heel,images were distorted,the level of organization was disappeared and signal intnsity was increased.The volunteers felt a slight discomfort at the coil entrance and support point of the heel.Conclusion Patients using 3.0T foot and ankle array coil for the Achilles tendon scanning could get high image quality and degrees of comfort.更多还原
