【摘要】：目的通過檢測(cè)宮頸癌介入栓塞治療前后磁共振彌散加權(quán)成像（DWI）表觀擴(kuò)散系數(shù)（ADC）值的變化情況，分析腫瘤范圍內(nèi)病灶突出部位的ADC值及其變化率與術(shù)后腫瘤大小的關(guān)系，從而探討磁共振DWI在宮頸癌介入栓塞術(shù)后早期療效評(píng)價(jià)中的應(yīng)用，尋求預(yù)測(cè)及監(jiān)測(cè)腫瘤療效的最佳時(shí)間點(diǎn)。 方法篩選44例采用介入栓塞治療的宮頸癌確診病例，于術(shù)前及術(shù)后第2天、5天、10天及15天行常規(guī)T2加權(quán)成像（T2WI）及彌散加權(quán)成像（DWI）檢查，b值選700和1500s/mm2，每次檢查均測(cè)量腫瘤大小、腫瘤及正常臀大肌ADC值。觀察每個(gè)監(jiān)測(cè)時(shí)間點(diǎn)腫瘤大小與不同b值的ADC值和ADC值變化率之間的關(guān)系。 結(jié)果b=700s/mm2時(shí)介入栓塞術(shù)前及術(shù)后第2天、5天、10天及15天腫瘤ADC值依次為0.97±0.11、1.07±0.18、1.24±0.13、1.35±0.12、1.41±1.17×10-3mm2/s，其中術(shù)后第15天測(cè)得病灶A(yù)DC值與第10天相比差異無統(tǒng)計(jì)學(xué)意義（p=0.122），其余各相鄰時(shí)間點(diǎn)間差異均有統(tǒng)計(jì)學(xué)意義（P0.05）；b=1500s/mm2時(shí)ADC值依次為0.79±0.09、0.84±0.15、0.95±0.13、1.04±0.16、1.14±0.17×10-3mm2/s，，各相鄰時(shí)間點(diǎn)間差異均有統(tǒng)計(jì)學(xué)意義（P0.05）。臀大肌不同b值下ADC值不同時(shí)間點(diǎn)間差異均無統(tǒng)計(jì)學(xué)意義（P0.05）。術(shù)前及術(shù)后各時(shí)間點(diǎn)腫瘤長(zhǎng)徑大小依次為3.86±1.15、3.36±1.12、2.94±1.12、2.45±1.08、2.25±1.00cm，術(shù)后不同時(shí)間點(diǎn)與術(shù)前腫瘤長(zhǎng)徑大小相比變化率為12.95%、24.54%、37.32%、43.27%。其中術(shù)后第10天及第15天腫瘤長(zhǎng)徑大小和其變化率之間無統(tǒng)計(jì)學(xué)差異，其余各相鄰時(shí)間點(diǎn)間差異均有統(tǒng)計(jì)學(xué)意義（P0.05）。當(dāng)b=1500時(shí)術(shù)后第10天腫瘤ADC值及其變化率與術(shù)后第5天、10天及15天的腫瘤長(zhǎng)徑大小均存在線性相關(guān)（P0.05），其中第10天腫瘤ADC值變化率與第15天腫瘤長(zhǎng)徑間關(guān)系程度最強(qiáng)（p=0.001，r=-0.726）。 結(jié)論介入栓塞治療對(duì)宮頸癌患者具有明顯療效，DWI具有評(píng)價(jià)宮頸癌介入栓塞術(shù)后療效觀察與判定的潛在價(jià)值，通過對(duì)ADC值的觀察初步發(fā)現(xiàn)術(shù)后第10天復(fù)查磁共振臨床價(jià)值最大，可以做為評(píng)價(jià)早期療效的最佳監(jiān)測(cè)點(diǎn)。
[Abstract]:Objective to investigate the changes of apparent diffusion coefficient (ADC) of diffusion weighted Mr imaging (DWI) before and after interventional embolization of cervical cancer, and to analyze the relationship between the ADC value and the postoperative tumor size.The purpose of this study was to explore the application of magnetic resonance (DWI) in the evaluation of early curative effect after interventional embolization of cervical cancer, and to find the best time point to predict and monitor the curative effect of cervical cancer.Methods 44 cases of cervical cancer diagnosed by interventional embolization were selected. T2WI and DWI were performed before and after operation. The tumor size was measured by T2-weighted T2WI and DWI. The tumor size was measured at each time.ADC of tumor and normal gluteus maximus muscle.The relationship between tumor size and ADC value and ADC value of different b value at each monitoring time point was observed.Results the ADC values were 0.97 鹵0.111.07 鹵0.181.24 鹵0.131.35 鹵0.121.41 鹵1.17 脳 10 ~ (-3) mm ~ (-2) / s before and on the second day after b=700s/mm2, respectively. There was no significant difference in ADC between the 15th day and the 10th day after b=700s/mm2, and there was no significant difference between the other adjacent time points.The ADC values were 0.79 鹵0.09 鹵0.84 鹵0.15 ~ 0.95 鹵0.13 鹵1.04 鹵0.16 鹵1.14 鹵0.17 脳 10 ~ (-3) mm ~ 2 路s ~ (-2 / s) respectively. There were significant differences among the adjacent time points (P < 0.05).There was no significant difference in ADC value between different time points under different b value of gluteus maximus muscle (P 0.05).The size of tumor long diameter was 3.86 鹵1.15t 3.36 鹵1.12C 2.94 鹵1.12C 2.45 鹵1.08U 2.25 鹵1.00 cm before and after operation, and the change rate was 12.95 ~ 24.54 ~ 37.32 ~ 37.32 鹵43.27 cm at different time points after operation.There was no statistical difference between the tumor length and the rate of change on the 10th and 15th day after operation, but there was significant difference between the other adjacent time points (P 0.05).There was a linear correlation between the tumor ADC value and the tumor length on the 5th and 15th day after operation, and the relationship between the ADC value on the 10th day and the tumor length diameter on the 15th day was the strongest.Conclusion the interventional embolization therapy has obvious curative effect on cervical cancer patients. DWI has potential value in evaluating the curative effect of cervical cancer after interventional embolization. The clinical value of magnetic resonance imaging is the most significant on the 10th day after operation through the observation of ADC value.It can be used as the best monitoring point to evaluate the early curative effect.
