MRI of the kidneys

MRI can identify the location, size, shape, and extent of the tumor. The mass can be identified as cystic, substantial, and fatty. It is more sensitive and accurate than CT. Basic Information Specialist classification: Urological examination classification: Nuclear magnetic resonance Applicable gender: whether men and women apply fasting: not fasting Tips: Serious damage to kidney function and pregnant women should be used with caution. Normal value The coronal planes of T1WI (A) and T2WI (B) showed normal morphology of the kidneys, no abnormalities in the renal parenchyma, and no dilatation of the double ureters. Clinical significance 1. MRI can clearly show the kidney, can distinguish the renal cortex and renal medulla without contrast agent. 2. MRI can identify the location, size, shape and extent of the mass; the mass can be identified as cystic, substantial, fatty, more sensitive than CT, qualitative and accurate. 3. Intravenous urography, MR examination can determine the location, nature or congenital dysplasia of the lesion. 4. The diagnosis of renal tuberculosis is better than CT. 5. Can better identify perirenal abscess, urinary cyst, lymphatic cyst and so on. 6. Can determine the location, extent of renal injury, perirenal hematoma or extravasation of urine and postoperative complications. 7. Non-invasive observation of the presence or absence of rejection after renal transplantation. 8. Whether MRI diagnosis of renal tumors must be superior to other imaging examinations such as CT, there is no conclusion yet. High results may be diseases: pararenal cysts, pediatric acquired immunodeficiency syndrome nephropathy, renal cancer, pediatric renal tuberculosis, pediatric allergic purpura nephritis, renal artery embolism, renal and ureteral duplication, renal cortical abscess, perirenal abscess matter Serious damage to kidney function and pregnant women should be used with caution. Inspection process MRI examination. Not suitable for the crowd Serious damage to kidney function and pregnant women should be used with caution.
