CT在肾脏疾病诊断中的应用价值

The Application Value of CT in the Diagnosis of Renal Disorders

本文分析了腹部平片,静脉肾盂造影,B 超及CT 对肾脏疾病的诊断价值。CT 的组织分辨力为普通X 线的十倍,并能提供二维图象,对肾囊肿,结石等疾病可作出定性及定量诊断。静脉肾盂造影有禁忌症限制。B 超受到肠道积气及脂肪影响。4cm 以上肿块行B 超导引穿刺,而深部小于4cm 病灶应行CT 导引下穿刺。

The diagnostic assessmerct of the renal disorders is analyzed by the compar-isons between Kidney-Ureter-Bladder(KVB),Intravenous Pyelography(IVP),B-Ultra-Sound(B-US),and Computed Tomography(CT)in this article,Computed Tomography(CT)can provide two-dimensional images.the density resolution of CT is ten times thatof common x-ray.The correct diagnosis can be made on the renal cyst and renal Calculus.IVP is Confined by some Controindictions while B-mode Vltrasound is remarkly interferedby colon gas and fats,Masses above 4 centimeters in diameter can be guided and biopsiedby B-Ultrasound,lesions less than 4cm in diameter Should be biopsied under the guidanceof CT.
