What Are The Differences Between A Ct And A Ct Urogram
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
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
Everyone has: lymph nodes in that region, so yes, it is common. The question is whether they look abnormal/enlarged or not. Did the report provide any more details on the lymph nodes? ...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
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 moreSee 1 more doctor answer
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 moreSee 1 more doctor answer
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.
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
Am i at a higher risk i had an episide of gross hematuria saw 2 different uros all testing cam eback neg two cyystoscopies cytologues renal us CT urogram CT scan nothing was found to explain this. My question is am i now at a highher risk for possible bl
No: You have had all the necessary tests by 2 urologists and nothing was found. Most likely the hematuria was from your prostate.If there was bladder tumor or kidney tumor or renal pelvic tumor the studies you had would have been diagnostic.If hematuria recurs, go back to your urologist.It sounds like you are OK. ...Read moreSee 1 more doctor answer
On a recent urogram, it came back as 11mmx8 mm a ureteral malignancy can not be excluded. Could a prior uterine reflux procedure be the cause of this?
Unlikely: The ureter runs from the kidney to the urinary bladder. It is not connected to the uterus. "Cannot exclude a malignancy" only means that there is an "indeterminate" abnormality, the radiologist is not sure what it is. Your doctor will probably want to look further into this, but it is not likely to be related to the reflux procedure. ...Read moreSee 1 more doctor answer
I was recently diagnosed with mild hydronephrosis by an ultra sound. Scheduled to have avCT Urogram. How accurate was the ultra sound? I tested posit
Mild hydronephrosis: Usually requires no further investigation that follow-up US in 3 - 6 months, unless you have symptoms such as pain or suspected mass. Mild hydronephrosis, if found incidentally, has likely been there all your life & requires no treatment. CT urogram is very expensive & likely unnecessary unless a reputable specialist explains why it is. Many PCPs do not understand grades of hydronephrosis! ...Read moreSee 1 more doctor answer
Different technology: Ct uses ionizing radiation, like xray, to produce images of the inside of your body. Mri uses a very powerful magnet to produce similar images. Each technology has it's strengths. For example, MRI is better at detecting stroke, while ct is better at detecting appendicitis. ...Read moreSee 1 more doctor answer
Difficult to get: into the physics of it here, but a "traditional" or single slice scanner requires a separate scan for each slice. A spiral ct or multislice scanner employs a single scan with multiple detectors to acquire the entire volume of of data in the region being scanned. The patient moves through the scanner as the tube scans/rotates around the patient hence the descriptor "spiral". ...Read more
CT colonoscopy: is a CT scan with specific technical parameters. There is a bowel prep to clear out the colon, and a tube is placed into the rectum to fill the colon with air. A barium enema uses x-ray/fluoroscopy instead of CT. With a rectal tube, the colon is filled with barium and air, and the patient placed in different positions for viewing. Barium enema has been largely replaced by colonoscopy. ...Read more
