【摘要】：目的:探討低劑量多層螺旋CT(MSCT)掃描后處理技術(shù)對(duì)腸梗阻診斷的增益價(jià)值。方法:回顧性分析83例臨床疑診腸梗阻患者的影像學(xué)資料,分別以常規(guī)橫斷位圖像、常規(guī)橫斷位聯(lián)合后處理技術(shù)重組圖像為2種評(píng)估依據(jù),診斷結(jié)果與臨床確診結(jié)果相比較,并進(jìn)行統(tǒng)計(jì)學(xué)檢驗(yàn)。后處理技術(shù)包括多平面重建(MPR)、最大密度投影(MIP)、容積再現(xiàn)(VR)。結(jié)果:常規(guī)橫斷位圖像診斷的敏感性為78.3%(47/60)、漏診率為21.7%(13/60);特異性為91.3%(21/23)、誤診率為8.7%(2/23);準(zhǔn)確性為81.9%(68/83)。常規(guī)橫斷位聯(lián)合后處理技術(shù)重組圖像的敏感性為95.0%(57/60)、漏診率為5.0%(3/60);特異性為95.7%(22/23)、誤診率為4.3%(1/23);準(zhǔn)確性為95.2%(79/83)。2種評(píng)估方法的敏感性、準(zhǔn)確性差異有統(tǒng)計(jì)學(xué)意義(P0.01)。結(jié)論 :低劑量MSCT掃描后處理技術(shù)在常規(guī)橫斷位圖像診斷的基礎(chǔ)上,可提高對(duì)腸梗阻的檢出率和準(zhǔn)確性,具有很好的臨床增益價(jià)值。
[Abstract]:Objective: to evaluate the gain value of low dose multislice spiral CT MSCT in the diagnosis of intestinal obstruction. Methods: the imaging data of 83 patients with clinically suspected intestinal obstruction were analyzed retrospectively. The conventional transection combined with post-processing technique is the basis of two kinds of evaluation, and the diagnostic results are compared with the results of clinical diagnosis. The post-processing techniques include multiplanar reconstruction MPRP, maximum density projection (MIP), volumetric reconstruction (VRV). Results: the diagnostic sensitivity of conventional transection images was 78.3% / 60%, the missed diagnosis rate was 21.713 / 60%, the specificity was 91.3% 21 / 23%, the misdiagnosis rate was 8.7% 23 / 23; The sensitivity of the reconstruction image was 95.00.57 / 60, the missed diagnosis rate was 5.0 / 60; the specificity was 95.772 / 23, the misdiagnosis rate was 4.33 / 23; the accuracy was 95.279,833.The sensitivity of the methods was 95.279,830.The. Conclusion: Low-dose MSCT post-processing technique can improve the detection rate and accuracy of intestinal obstruction on the basis of conventional transverse image diagnosis and has good clinical gain value.
