摘要:
目的:探討MRI對(duì)髕骨軟化癥診斷的可靠性。方法:共納入患有膝前疼痛經(jīng)臨床初步診斷為髕骨軟化癥的中青年病人112例,先行膝關(guān)節(jié)MRI檢查,再行膝關(guān)節(jié)鏡檢查驗(yàn)證,并將MRI所示髕骨損傷情況與關(guān)節(jié)鏡所見比較。結(jié)果:關(guān)節(jié)鏡檢查證實(shí)有膝前疼痛表現(xiàn)的112例患者中,存在髕骨軟化者50例(45%),滑膜肥厚50例,半月板撕裂8例,股脛關(guān)節(jié)軟骨損傷8例和未見形態(tài)異常者12例。1.5T MRI檢出髕骨軟化癥的陽性率為75%(95%可信區(qū)間,53%~89%),陰性率為72%(95%可信區(qū)間,56%~84%),其敏感性為60%(95%可信區(qū)間,41%~77%),特異性為84%(95%可信區(qū)間,2%~49%),診斷準(zhǔn)確率為73%(95%可信區(qū)間,60%~83%)。Ⅰ度損傷的敏感度為13%(95%可信區(qū)間,2%~49%),Ⅱ、Ⅲ或Ⅳ度損傷的敏感度為83%(95%可信區(qū)間,59%~94%)。結(jié)論:根據(jù)臨床癥狀和目前物理檢查方法不能診斷髕骨軟化癥。1.5T的MRI診斷Ⅰ度軟骨損傷的敏感度較低,而對(duì)Ⅱ、Ⅲ或Ⅳ度損傷的敏感度很高。MRI檢查可以作為較重髕骨軟化癥的一種診斷方法。
