摘要
目的探讨多层螺旋CT（MSCT）三维重建技术在泌尿系统损伤中的应用价值。方法对43例泌尿系统损伤的患儿行MSCT后，应用三维重建技术对横断面图像进行容积重建（VR）、最大密度投影（MIP）及多平面重组（MPR），获得完整的尿路影像。由两名副主任医师负责图像分析及诊断。结果43例患儿中，单纯肾挫伤5例、肾挫裂伤伴包膜下血肿5例、肾挫裂伤伴肾周血肿4例、。肾挫裂伤伴肾上腺血肿2例、肾撕裂伴尿外渗13例、肾撕裂伴肾蒂损伤3例、肾撕裂伴输尿管损伤6例、骨盆骨折伴后尿道断裂2例、膀胱壁损伤伴膀胱内血凝块3例。结论MSCT具有扫描速度快、覆盖范围广、图像质量高及薄层扫描的特点，对儿童泌尿系统损伤的诊断具有优势。
Objective To investigate the application value of three-dimensional reconstruction tech- nique of mutislice spiral CT（MSCT）in children urinary tract injuries. Methods Forty-three patients with uri- nary tract injury performed MSCT scan, and three-dimensional reconstruction technique was used for volume rendering, maximum intensity projection and multi-planar reformation, urinary tract imaging was acquired completely. The images were reviewed by two experienced radiologists. Results Of the 43 cases, there were 5 simple contusion of kidney, 5 contusion and laceration of kidney accompanied with subcapsular haematoma, 4 contusion and laceration of kidney accompanied with perinephric haematoma, 2 contusion and laceration of kidney accompanied with adrenal haematoma, 13 shattered kidney accompanied with extravasation of urine, 3 shattered kidney accompanied with renal pedicle injury, 6 shattered kidney accompanied with ureter injury, 2 pelvic fracture accompanied with posterior urethra split, 3 contusion of urinary bladder wall accom- panied with blood clot in the urinary bladder. Conelusion MSCT has the characteristic of high scanning speed, wide overlay scope, high image quality and thin slice scan. It is an effective modality in the evaluation of children urinary tract injuries.
