作者对34例局部晚期膀胱癌在放化疗前用膀胱镜、双手扪诊、TUR及CT评价局部肿瘤情况,治疗后除CT扫描外,还作了TUR(17)、钳取活检(10)、部分膀胱切除(1)或膀胱切除(6)来评价疗效。用第三代Somatom,SF 扫描仪,膀胱充填造影剂,密度为120HU,以高剂量技术(520投影/8Sec),层面8mm 厚。CT 规定肿瘤全效是有正常的膀胱壁或疤痕形成;肿瘤残存是见瘤块,膀胱壁轮廓不规则、膀胱周围组织边缘不清或膀胱壁不规则增厚;CT 提示疤痕为膀胱短小,
The authors evaluated 34 cases of locally advanced bladder cancer with cystoscopy, palpation with both hands, TUR and CT before radiotherapy and chemotherapy. TUR (17) and forceps biopsy (10) were performed after CT scan. Partial cystectomy (1) or cystectomy (6) to evaluate the efficacy. With a third-generation Somatom, SF scanner, the bladder was filled with contrast media at a density of 120HU with a high dose of technology (520 Projection / 8Sec) and 8mm thick. CT provides the full effect of the tumor is a normal bladder wall or scar formation; residual tumor is seen tumor mass, irregular bladder wall contour, unclear margins around the bladder or bladder wall irregular thickening; CT tips for the short bladder,
