【摘要】 目的：研究经颅多普勒（ＴＣＤ）评估蛛网膜下腔出血患者脑血流量（ＣＢＦ）的价值。方法：３１例蛛网膜下腔出血患者同时做了ＴＣＤ及１３３Ｘｅ吸入法测定ＣＢＦ。结果：蛛网膜下腔出血患者平均血流速度（Ｖｍ）升高者，则相应区域ＣＢＦ降低，呈负相关（ｐ＜０．０１）；而Ｖｍ降低者则相应区域ＣＢＦ亦降低，呈正相关ｐ＜０．０１。病情越严重则ＴＣＤ－Ｖｍ升高或降低越明显，ＣＢＦ亦明显下降。结论：ＴＣＤ可以有效判断蛛网膜下腔出血患者的脑血流量。更多还原

【Abstract】 Objective:To study the ultrasound feature in correlation with pathological structure of adrenal cortex carcinoma.Methods:Retrospective study was done in 14 patients with adrenal cortex carcinoma diagnosed by two dimensional and color Doppler sonography and by pathology.Results:Ultrasound and pathology correlated study indicated that a group of isoechogencity was accounted for 43%(6/14),a group of high echo was 29% (4/14),a group of low echo was 14% (2/14) and a group of mixed echo was 14%(2/14).The rate of coincidence of qualification was 57%(8/14),the rate of coincidence of locality was 93%(13/14).The features of ultrasound image of adrenal cortex carcinoma were 1)The tumor was big,mainly isoechogenic,more than 8 2cm in diameter;2)The tumor shape was varied,irreqular or multilobar;3)Color Doppler showed plenty blood supply of the tumor and its surroundings and 4)Tumor necrosis frequently seen.Conclusion:Different tumor echos were correlated the tumor size,the tumor cell arrangement,the vascularity,the fibril tissue and necrosis.更多还原
