【摘要】：目的探討能譜CT物質(zhì)定量分析與肝癌TACE術(shù)后碘油沉積情況的相關(guān)性及其臨床價(jià)值。方法對(duì)28例原發(fā)性肝癌患者TACE術(shù)前進(jìn)行能譜CT掃描,術(shù)后1個(gè)月CT復(fù)查。利用能譜分析軟件(GSI)對(duì)術(shù)前能譜圖像進(jìn)行后處理,用混合能量和單能量圖像對(duì)病灶進(jìn)行觀察,分別記錄動(dòng)脈期、靜脈期腫瘤病灶碘基值及對(duì)比術(shù)后復(fù)查圖像病灶碘油沉積區(qū)域和無(wú)碘油沉積區(qū)域術(shù)前碘基值、腹主動(dòng)脈和門靜脈碘基值。結(jié)果術(shù)后僅1例病灶碘油完全沉積。術(shù)后碘油沉積面積50%病灶的術(shù)前動(dòng)脈期標(biāo)準(zhǔn)化碘濃度(ANIC)較術(shù)后碘油沉積面積50%的病灶高,分別為0.25±0.04、0.18±0.06(P0.01),標(biāo)準(zhǔn)化碘濃度比率(ICratio)及靜脈期標(biāo)準(zhǔn)化碘濃度(VNIC)差異無(wú)統(tǒng)計(jì)學(xué)意義。同一病灶碘油沉積區(qū)域動(dòng)脈期標(biāo)準(zhǔn)化碘濃度(ANIC)較無(wú)碘油沉積區(qū)域高,分別為0.21±0.05、0.16±0.06(P0.01)。結(jié)論利用能譜CT測(cè)得的動(dòng)脈期標(biāo)準(zhǔn)化碘基值可以較好的預(yù)測(cè)TACE術(shù)后肝癌病灶碘油沉積情況,從而對(duì)評(píng)價(jià)肝癌預(yù)后及為TACE術(shù)篩選合適病例提供一定參考。
[Abstract]:Objective to investigate the correlation between quantitative analysis of energy dispersive CT materials and lipiodol deposition after TACE and its clinical value. Methods 28 patients with primary liver cancer were examined by energy dispersive CT before TACE and 1 month after operation. Energy spectrum analysis software (GSI) was used to post-process the preoperative energy spectrum images. The lesions were observed with mixed energy and single energy images. The arterial phase was recorded respectively. The iodine base value of the tumor focus in venous phase and the iodine base value before operation and abdominal aorta and portal vein iodine base value in the focus of lipiodol deposition and no lipiodol deposition were compared. Results only 1 case had complete deposition of lipiodol. The preoperative arterial standardized iodine concentration (ANICI) of 50% lipiodol depositional area was higher than that of 50% of postoperative lipiodol deposition area (0.25 鹵0.04 鹵0.18 鹵0.06 P0.01C). There was no significant difference in the standardized iodine concentration ratio (ICratioI) and the venous phase standardized iodine concentration (VNICs). The standardized iodine concentration (ANIC) in the arterial phase of lipiodol deposition area in the same lesion was higher than that in the non-lipiodol depositional area, which was 0.21 鹵0.05 鹵0.16 鹵0.06 (P 0.01), respectively. Conclusion the standardized iodine base value of arterial phase measured by EDS can be used to predict the lipiodol deposition of hepatocellular carcinoma after TACE, which provides a reference for evaluating the prognosis of HCC and screening suitable cases for TACE.
