摘要
目的:探讨多层螺旋CT扫描在泌尿系统三维成像中的应用价值。方法:拟对在本院诊治的106例泌尿系统病变患者进行MSCTU平扫、增强、延迟扫描的病例进行回顾性整理,采用曲面重组法(CPR)、最大密度投影法(MIP)、多平面重组法(MPR)及容积成像法(VR)等三维重建技术对原始数据进行重建和分析。结果:MSCTU尿路成像能够清晰显示泌尿系统全貌,同时显示泌尿系统与附近结构和器官的相互关系。106例患者中,共检出泌尿系统结石71例,其中肾结石35例,输尿管结石20例,肾脏及输尿管多发结石16例;先天性发育畸形7例,包括3例双肾盂双输尿管畸形,2例巨输尿管,l例输尿管囊肿和1例马蹄形肾;肾囊肿4例,包括2例单侧囊肿,2例双侧囊肿;肾脏、输尿管、膀胱肿瘤14例,包括4例肾癌、5例输尿管癌和5例膀胱癌;肾脏创伤、肾内血肿3例;输尿管狭窄7例。结论:MSCTU扫描时间短,图像质量好,可获得不同层面、不同角度的三维图像,能良好地显示泌尿系统病变的位置、形态、解剖关系、毗邻关系、血供情况及性质。
Objective:To explore the application value of multi-slice spiral CT in urinary system of three-dimensional imaging.Method:The quasi on plain MSCTU scan, enhancement, delayed scanning in 106 cases of urinary system disease patients in our hospital were retrospectively sorting,the original data were analyzed using surface recombination method (CPR), maximum intensity projection (MIP), multi planar reconstruction (MPR) and volume rendering (VR) and other 3D reconstruction methods.Result:MSCTU urinary tract imaging can clearly display the urinary system, also showed a correlation between urinary system and nearby structures and organs.In 106 cases, 71 cases of urinary calculi were detected, including 35 cases of renal calculi, 20 cases of ureteral calculi, 16 cases of renal and ureteral multiple stones; and congenital malformation in 7 cases, including 3 cases of double renal pelvis and double ureter, 2 cases of megaureter, ureter cyst cases L and 1 cases of horse hoof shaped kidney; renal cysts in 4 cases, including 2 cases of unilateral cyst, 2 cases of bilateral cyst; kidney, ureter, bladder tumor in 14 cases, including 4 cases of renal cell carcinoma, 5 cases of ureteral carcinoma and 5 cases of bladder cancer; 3 cases of kidney trauma, renal hematoma; ureteral stenosis in 7 cases.Conclusion:MSCTU scan time is short, the image quality is good, the three-dimensional image can be obtained at different levels, from different angles, can be a good show urinary system disease location, morphology, anatomy, adjacent relations, the blood supply and properties for diagnosis and clinical treatment of diseases of the urinary system has the unique value in clinical application.
