【摘要】：目的研究后顱凹實(shí)質(zhì)型血管母細(xì)胞瘤的MRI特征,提高其影像學(xué)診斷水平。方法觀察經(jīng)病理證實(shí)的60例后顱凹實(shí)質(zhì)型富血供腫瘤(實(shí)質(zhì)型血管母細(xì)胞瘤20例,非血管母細(xì)胞瘤40例)的血管流空影、DWI信號(hào)特點(diǎn),測(cè)量ADC值并進(jìn)行統(tǒng)計(jì)學(xué)比較。結(jié)果 20例實(shí)質(zhì)型血管母細(xì)胞瘤均有血管流空影,DWI像呈等或稍低信號(hào)18例,高信號(hào)2例,平均ADC值(1.95±0.17)×10~(-3)mm~2/s;40例非血管母細(xì)胞瘤有血管流空影6例,無血管流空影34例,DWI像呈等或稍低信號(hào)5例,高信號(hào)35例,平均ADC值為(0.93±0.13)×10~(-3)mm~2/s。經(jīng)統(tǒng)計(jì)學(xué)比較,兩者在是否有血管流空影、DWI信號(hào)的χ~2值分別為39.231、33.878,P值均0.05,ADC值間比較t=25.788,P0.05,差異均有統(tǒng)計(jì)學(xué)意義。結(jié)論存在血管流空影,DWI呈等或稍低信號(hào)及對(duì)應(yīng)的較高的ADC值對(duì)提示后顱凹實(shí)質(zhì)型血管母細(xì)胞瘤有價(jià)值。
[Abstract]:Objective to study the MRI features of posterior fossa parenchymal hemangioblastoma and to improve its imaging diagnosis. Methods 60 cases of parenchymal hemangioblastoma of posterior cranial fossa (20 cases of parenchymal hemangioblastoma) proved by pathology were observed. ADC values were measured and compared statistically. Results all 20 cases of parenchymal hemangioblastoma showed iso-or slightly low signal intensity, and 2 cases had high signal intensity. The mean ADC value was 1.95 鹵0.17 脳 10 ~ (-3) ~ (-2) / s ~ (-1) / s in 40 cases of non-hemangioblastoma, in which 6 cases had vascular flow void imaging, 34 cases had iso-or slightly low signal intensity, 35 cases had high signal intensity, and the average ADC value was 0.93 鹵0.13 脳 10 ~ (-3) mm ~ (-2 / s). Compared with the statistical analysis, the mean value of ADC was 0.93 鹵0.13 脳 10 ~ (-3) mm ~ (-2 / s), and the mean ADC value was 0.93 鹵0.13) 脳 10 ~ (-3) mm / s. The 蠂 ~ 2 value of DWI signal was 39.231 ~ 33.878g ~ (-1) (P = 0.05), respectively. The difference was statistically significant. Conclusion there is an equal or slightly low signal on DWI and a higher ADC value in the posterior cranium. Concave parenchymal hemangioblastoma is valuable.
