A computed tomography urography ( CT urography or CT urogram) is a computed tomography scan that examines the urinary tract after contrast dye is injected into a vein.
Three-dimensional reconstructed CT scan image of a ureteral stent in the left kidney (indicated by yellow arrow). There is a kidney stone in the pyelum of the lower pole of the kidney (higher red arrow) and one in the ureter beside the stent (lower red arrow).
A computed tomography scan ( CT scan; formerly called computed axial tomography scan or CAT scan) is a medical imaging technique used to obtain detailed internal images of the body. [2] The personnel that perform CT scans are called radiographers or radiology technologists.
Urethrogram showing an urethra stricture in a man. A retrograde urethrography [1] is a routine radiologic procedure (most typically in males) used to image the integrity of the urethra . Hence a retrograde urethrogram is essential for diagnosis of urethral injury, or urethral stricture. [2] [3]
The choice of imaging depends on the clinical presentation (history, symptoms and examination findings). In the case of renal colic (one sided loin pain usually accompanied by a trace of blood in the urine) the initial investigation is usually a spiral or helical CT scan.
It can also be used ureteroscopy, or to delineate renal anatomy in preparation for surgery. Retrograde pyelography is generally done when an intravenous excretory study ( intravenous pyelogram or contrast CT scan) cannot be done because of renal disease or allergy to intravenous contrast.
A CT scan or MRI of the pelvis or abdominal region can show signs of kidney or bladder cancer, for instance.
A full-body scan is a scan of the patient's entire body as part of the diagnosis or treatment of illnesses. If computed tomography ( CAT) scan technology is used, it is known as a full-body CT scan, though many medical imaging technologies can perform full-body scans.
A CT scan or MRI of the pelvis or abdominal region can show signs of kidney or bladder cancer, for instance.
Renal stones, appendicitis, pancreatitis, diverticulitis, abdominal aortic aneurysm, and bowel obstruction are conditions that are readily diagnosed and assessed with CT. CT is also the first line for detecting solid organ injury after trauma.
