为比较非增强螺旋CT和排泄性尿路造影对肾绞痛的诊断价值,作者对53例病人进行了研究。男32例,女21例,年龄18～72岁。CT层厚5mm,从胸_(12)椎体至耻骨连续扫描,一次或两次屏气,总扫描时间为40～50s。然后以3mm间隔重建,产生103个重建像,输入到工作站。先在横断面上解释螺旋CT平扫所见。输尿管腔内存在着高密度结构为结石。在某个平面以上单侧输尿管扩张,该平面以下管腔正常则为梗阻。继发征象包括:输尿管周围和肾周围脂
To compare the diagnostic value of non-enhanced helical CT and excretion urography on renal colic, we conducted a study of 53 patients. 32 males and 21 females, aged 18 to 72 years. CT layer thickness 5mm, from the chest _ (12) vertebral body to the pubic continuous scan, hold breath once or twice, the total scan time is 40 ~ 50s. Then reconstructed at 3mm intervals, resulting in 103 reconstructed images that were input to the workstation. Explain in a cross-sectional view spiral CT scan first. Ureteral lumen exists in the high-density structure of stones. Unilateral ureteral dilatation above a certain plane, the lumen below the plane is normal obstruction. Secondary signs include: around the ureter and perirephric fat
