【摘要】：目的探討乳腺彈性成像中對(duì)照組織的大小對(duì)彈性應(yīng)變率比值及診斷準(zhǔn)確性的影響。方法選擇病灶組織位置、大小不變的情況下,按對(duì)照組織大小分為4組,對(duì)照組織≥病灶組織(A組);病灶組織對(duì)照組織≥1/2病灶組織(B組);1/2病灶組織對(duì)照組織≥1/4病灶組織(C組);對(duì)照組織1/4病灶組織(D組)。對(duì)114例患者共139個(gè)乳腺病灶進(jìn)行4組彈性應(yīng)變率比值的測(cè)定,以病理診斷為基礎(chǔ),觀察4組對(duì)照組織的大小對(duì)彈性應(yīng)變率比值及良惡性病灶鑒別診斷的效能。結(jié)果 4組對(duì)照組織的大小對(duì)彈性應(yīng)變率比值差異無統(tǒng)計(jì)學(xué)意義(P0.05)。4組診斷乳腺惡性病變的敏感性、特異性、準(zhǔn)確性均較為接近,A、B、C、D組ROC曲線下面積分別為0.935、0.932、0.923、0.905,4組ROC曲線的兩兩比較,差異無統(tǒng)計(jì)學(xué)意義(P0.05)。以3.08為界點(diǎn),A組漏診3例,誤診5例;B組漏診4例,誤診5例;C組漏診5例,誤診6例;D組漏診5例,誤診9例。結(jié)論以病理診斷為金標(biāo)準(zhǔn),對(duì)照組織的大小對(duì)彈性應(yīng)變率比值及診斷結(jié)果無明顯影響。
