European Radiology:舟骨韧带撕裂患者的影像学评估:定量评估的选哪个?

2022-04-14 shaosai MedSci原创

舟骨背侧移位(SDD)目前是舟骨不稳定患者的负面预后因素,常提示需进一步的手术治疗。

舟骨不稳定(SLI)的诊断在临床上具有挑战性,舟骨骨间韧带(SLIL)的损伤是产生舟骨不稳定的主要因素之一。舟骨背侧移位(SDD)是一个重要的诊断因素,但其评估的标准至今没有明确的指南。同时,SDD目前是舟骨不稳定患者的负面预后因素,常提示需进一步的手术治疗。此外,以往的研究表明,SDD 的程度与舟骨不稳定的严重程度和骨关节炎的存在相关。因此,建立一个可靠的评估SDD定量成像方法十分重要

Chan等学者使用标准X线20名患者进行研究结果证实使用背侧切线(DTL)方法最实用,且可靠性较高。然而,X线片很容易受到病人定位问题的影响,对识别早期腕关节不稳定的敏感性较低。因此,Teixeira等学者提出在CT图像上测量桡骨后角(PRSA)进行评估,定义为舟骨窝表面平面与舟骨最后点之间的角度。Meister等学者指出,定义为矢状面MR图像上SDD相对于桡骨关节面的比率放射状舟骨同位率(RSCR)与SLIL撕裂呈正相关。

近日,发表在European Radiology杂志的一项研究比较四种不同的SDD定量评估方法(传统X线片上的DTL,CT和MR上的PRSA,以及MR上的RSCR)每种方法得到的数值都与SLIL撕裂和腕关节软骨病(舟骨高级塌陷(SLAC))进行相关性分析为进一步优化和规范背侧舟骨脱位的成像评估提供了数据支持

项研究前瞻性地纳入160名连续接受CT关节造影检查以评估疑似舟骨韧带撕裂的患者。其中65名患者的MR图像可用。两位读者使用背切线(DTL)方法独立评估了常规X线片上的舟骨位移,CT和MR上的桡骨后角(PRSA)以及MR上的桡骨同位比。这些测量结果在有和没有舟骨韧带撕裂的患者组中进行了比较。 

CT上的DTL和PRSA的测量结果优秀(ICC=0.93和0.88),MR上的PRSA良好(ICC=0.65),而RSCR中等(ICC=0.49)。在正常和破裂的SLIL患者之间,CT上的DTL和PRSA值有明显增加(P < 0.0001)。基于MR的方法也有同样的趋势,但这些差异只在一个读者有意义。唯一能区分正常和部分破裂的SLIL患者的方法是CT上的PRSA。CT上的PRSA对SLIL破裂的诊断效果最好(敏感性和特异性为70-82%和70-72%)。 


图 a, b 轴位和冠位CT关节造影图像,显示了舟骨背侧部分的撕裂(脂肪箭头)。 c, d 两位读者认为背侧切线(c)是正常的(-0.5和-1.1毫米),而CT上两位读者认为桡骨头后角(d)是异常的(105°和112°)

本研究表明,对于SDD的定量评估,标准X线片上的DTL和CT上的PRSA是最一致的成像指标,具有很好的观察者间可重复性,异常值与CT关节造影上的SLIL撕裂和软骨病变密切相关。CT上的PRSA是唯一可以区分CT关节造影上正常和部分撕裂的SLIL患者的方法。两种被评估的基于MR的方法的观察者之间的可重复性都很好,与CT关节造影结果的相关性较差。
