Role of Contrast Agent in the Diagnosis of Renal Diseases in Computed Tomography

Abstract

Renal diseases often result from combination of factors, mass of renal system are more common in people whose have a symptoms of renal diseases diet is very high in animal protein or who do not drink enough water main causes of renal diseases. The purpose of this research was to identify the role of contrast media (CM) in the diagnosis of renal diseases in CT. Fifty consecutive patients with flank pain were examined by CT with CM over a period of 2 months, all patients were prospectively defined as either positive or negative renal diseases 16 patients out of 50 with kidney mass, 12 patients out of 50 with stone and 8 patients with renal cyst and 14 patient out of 50 with other renal diseases. The result of this study revealed that CT is the modality of choice for detecting renal diseases; CT with CM is reserved when CT without CM is not clear. Contrast enhanced CT was able to identify the Inflammatory diseases, renal masses and Metastases. Non-enhanced lesions were simple cyst, abscess and renal ischemia.
