Had routine ct's with contrast and without, for kidney stones. Now they want to send me for a CT urogram. What is the difference?

Had routine ct's with contrast and without, for kidney stones. Now they want to send me for a CT urogram. What is the difference?

Contrast: A plain ct looks for stones. A ct urogram uses IV contrast (dye) to better evaluate the renal pelvis and ureter (the "tube" connecting your kidneys to your bladder). These structures are not well seen without contrast. A greater amount of contrast is used in a urogram than normal contrast ct to better fill these structures. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! the image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

Why doesnt a MRI show deflux material from a prior VUR and a CT Urogram does? I thought MRI's are more in depth?

Different tests: An MRI uses an atom's response to a strong magnetic field. A CT uses X-rays. The X-rays won't pass through the contrary, so it creates a shadow. No such effect occurs because of the magnetic field. ...Read more

I had a cystoscopy, the doctor said everything is normal but we will have CT urogram, if everything is normal why the CT urogram should be done?

Evaluate other areas: Cystoscopy and cystoureteroscopy are very good at looking at the inside of the bladder, ureters and renal collecting systems. Ct urogram looks there as well, but also evaluates the "outsides" (the parts that cannot be seen with a scope) of these structure and the other structures in the abdomen and pelvis. ...Read more

Will a CT Urogram show recent kidney infections or stones that passed?

Will a CT Urogram show recent kidney infections or stones that passed?

No: No, stones that passed out of the body are gone. It will show any remaining stones. There may temporarily be some residual signs of the obstruction caused by the stone, however. Also, if an infection has resolved, the CT might temporarily show some residual signs of the infection, but will otherwise be normal unless the infection resulted in scarring of the kidney. ...Read more

Would Deflux material which is injected under the L ureter where it enters the bladder show up on a CT urogram as a possible ureteral malignancy?

Would Deflux material which is injected under the L ureter where it enters the bladder show up on a CT urogram as a possible ureteral malignancy?

Can create confusion: On CT, Deflux is fluid density & occasionally can calcify creating confusion with ureterocele or distal ureteral stone at the bladder base ureterovesicular junction. If the ct urogram (workup for hematuria) interpreting radiologist is not aware of this pertinent history of prior injection, it may create some confusion in interpretatation. Make sure to Inform the radiologist about this history! ...Read more

How often does a "retroperitoneal attenuation" (found on CT urogram) turn out to be lymphoma? My dad is being tested for this. PET scan next. Worried.

How often does a "retroperitoneal attenuation" (found on CT urogram) turn out to be lymphoma? My dad is being tested for this. PET scan next. Worried.

Not often: Retro peritoneal attenuation is and unusual term on ct. CT is usually very good at detecting enlarged lymph nodes of lymphoma . And understand that not all lymphomas will be best seen with PET. Also not every positive PET CT is cancer. There are other disease entities that are positve on PET. Talk honestly with the doctor to wxplain the results ...Read more

Had report of adrenal hyperplasia on CT urogram. All labs BP, normal. No symptoms. Is this a normal variant? Male age 62 ideal body weight.

Had report of adrenal hyperplasia on CT urogram.  All labs BP, normal.  No symptoms.  Is this a normal variant?  Male age 62 ideal body weight.

Here are some...: Most likely, the reported finding on CT Urogram is merely incidental and carries no clinical importance. As a F/U for a peace of mind, repeating a CT in a year is reasonable. Of course, the most logical timing of F/U should be deduced with working closely with your treating doc since she/he surely knows more pertinent information about you. ...Read more
