【摘要】：目的探討超聲、CT和磁共振成像(MRI)對(duì)于血管平滑肌脂肪瘤(AML)病理特征與影像學(xué)表現(xiàn)的相關(guān)性。方法收集18例無脂肪AML患者臨床檢查資料,平均(54.2±12.0)歲,其中女13例,男5例。無脂肪AML患者行CT、MRI及超聲檢查,與臨床組織學(xué)檢查結(jié)果進(jìn)行統(tǒng)計(jì)學(xué)分析。結(jié)果患者腎臟皮髓交界相(CM)和骨盆延遲實(shí)質(zhì)相(NG)的AML平均增強(qiáng)值均小于相鄰?fù)瑐?cè)正常腎皮質(zhì)組織(CP)(P0.000 1);所有患者AML部位的T2W信號(hào)強(qiáng)度較CP低,T2WSIR平均值為(0.61±0.1);動(dòng)態(tài)增強(qiáng)掃描衰減差異為負(fù)值的輸出或E值的輸出分型與病理診斷血管數(shù)間無顯著相關(guān)性(P=0.68),AML回聲反射與組織學(xué)診斷特征間無顯著相關(guān)性(P0.05);AML患者CT等衰減和高倍視野脂肪細(xì)胞比例25%存在顯著相關(guān)性(P=0.01);高倍視野脂肪細(xì)胞比25%的患者在MRI檢查中也存在可見的脂肪組織(P=0.04)。結(jié)論多數(shù)無脂肪AML成像特征主要包括非對(duì)比增強(qiáng)CT(NECT)的高衰減,較低的T2W MRI信號(hào)強(qiáng)度,CT等衰減和高倍視野脂肪細(xì)胞比例25%之間存在顯著相關(guān)性為臨床診斷無脂肪AML提供一定的借鑒意義。
[Abstract]:Objective to investigate the correlation between pathological features and imaging features of angiomyolipoma (AMLL) by ultrasound CT and magnetic resonance imaging (MRI). Methods the clinical data of 18 patients with AML without fat were collected. The average age was 54.2 鹵12.0 years old, including 13 females and 5 males. CTU MRI and ultrasonography were performed in non-fat AML patients, and the results were statistically analyzed with clinical histology. Results the average enhancement value of AML in the renal dermatomedullary junction phase (CMM) and pelvic delayed parenchymal phase (AML) was lower than that in the adjacent ipsilateral normal renal cortical tissue (P 0.000 1), and the T2W signal intensity of all patients with AML was lower than that of CP and the mean value of T2WSIR in all patients was 0.61 鹵0.1g, and dynamic enhancement was also observed in all patients. There is no significant correlation between the output of negative value or E value and the number of vessels diagnosed by pathology. There is no significant correlation between echo reflex of P0. 68 / AML and histologic diagnosis. There is no significant correlation between CT iso-attenuation and high power field adipose fine in patients with P0. 05 or AML. There was a significant correlation between 25% and 25% of the patients with high power field adipocyte ratio, and there was also a presence of adipose tissue in the MRI examination in 25% of the patients with high power field of vision. Conclusion the main features of fat free AML imaging include the high attenuation of non-contrast enhanced AML. There is a significant correlation between the low T2W MRI signal intensity and the ratio of adipocytes in high power field and the ratio of adipocytes in high power field. It is useful for clinical diagnosis of adipose AML.
