Kidney CT for blood in urine is a diagnostic test to rule out kidney cancer and urinary bladder cancer. Blood in urine without pain is called painless hematuria. How ultrasound, CT, and MRI are used to diagnose kidney disease? When CT or MRI should be used? Even if ultrasound of kidneys is normal. Leading CT and MRI radiologist answers questions on use of kidney CT in patients with blood in urine, without pain (painless hematuria).
Kidney CT for blood in urine (painless hematuria). How is kidney cancer diagnosed? Dr. Anton Titov, MD. Video interview with leading expert in radiology, CT and MRI specialist. Dr. Kent Yucel, MD. CT and MRI of the kidney is used for Kidney cancer diagnosis. Abdominal MRI scan can find masses in kidneys and adrenal glands and urinary bladder. Dr. Kent Yucel, MD. CT and MRI are also used in chronic kidney disease but biopsy is the test of choice in medical kidney disease. Renal cell carcinoma is diagnosed by finding blood in urine (painless hematuria) and CT urography and flexible cystoscopy. Flexible endoscopic cystoscopy is also used in diagnosis of urinary bladder cancer. Medical Second Opinion confirms that CT findings and MRI findings of kidneys to detect renal carcinoma are accurate. Medical Second Opinion also helps to choose the best treatment strategy for renal cancer and urinary bladder cancer. Seek medical Second Opinion on kidney cancer and be confident that your treatment is the best. Magnetic resonance imaging of the renal arteries is also possible but is still in testing phase. Dr. Kent Yucel, MD. CT urography is a frequent diagnostic test in the hematuria clinic. Asymptomatic microhematuria requires CT urography and MRI of kidneys. Advanced imaging is also used for water distention of kidney diagnosis, hydronephrosis. MRI of kidneys to diagnose cancer / renal cell carcinoma. Dr. Anton Titov, MD. To stay in the abdominal area, let's touch upon MRI and CT studies of the kidneys and adrenal glands. When kidney MRI or kidney CT is indicated? Dr. Anton Titov, MD. When it can benefit someone with a known or suspected kidney disease? Dr. Anton Titov, MD. Dr. Kent Yucel, MD. Kidney disease falls into three categories. There is disease of the kidney itself. It causes the kidneys to fail. That is usually evaluated by kidney biopsy and there is very little role for imaging in kidney diseases of that kind. Dr. Kent Yucel, MD. We call that diffuse or medical kidney disease. Then there is kidney tumors. Renal tumors generally present with blood in the urine blood that you can't see. Maybe blood that is only detectable by looking at the urine under the microscope. Dr. Anton Titov, MD. Painless hematuria. Dr. Kent Yucel, MD. Painless hematuria we call that. Those tumors can be diagnosed by imaging. Ultrasound is usually the first choice. But ultrasound also can miss small tumors. So many older patients have blood in their urine, they may have renal CT or MRI scan even if ultrasound of kidneys is normal. And the third area of kidney disease is blockage of the urine coming out the kidneys going into the bladder. That tube that leads from the kidneys into the bladder is called a ureter. So something is blocking of a ureter. The name for it is hydronephrosis, or water distention of the kidney. And that is evaluated by ultrasound primarily. And similar to the bile duct situation, the ultrasound is very good at showing blockage. But ultrasound is not so good at showing the cause of blockage. Sometimes there is no blockage then patients are generally done with that imaging of kidney. But if ultrasound shows blockages then they will generally go on to the next diagnostic step. This is the CT or MRI of the kidneys. It can show what is causing the blockage. Kidney CT for blood in urine (painless hematuria) Video interview with leading expert in radiology. Dr. Kent Yucel, MD.
