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.
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.
OPS-301 code. 3-706. Radioisotope renography is a form of medical imaging of the kidneys that uses radiolabelling. A renogram, which may also be known as a MAG3 scan, allows a nuclear medicine physician or a radiologist to visualize the kidneys and learn more about how they are functioning. [1]
Therefore, they are often now replaced by ultrasonography and magnetic resonance imaging (MRI). Also, the iodinated contrast medium used in contrast CT and contrast radiography can cause allergic reactions, including severe ones. [5] The contrast dye may also be toxic to the kidneys. [7]
Magnetic resonance imaging ( MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. MRI does not involve X-rays or the use of ionizing ...
Retrograde urethrogram. 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]
In order to assess these structures radiographically, a technique called an intravenous pyelogram was historically utilized, and today at many institutions CT urography is the technique of choice.
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.
Types of presentations of CT scans: - Average intensity projection. - Maximum intensity projection. - Thin slice ( median plane) - Volume rendering by high and low threshold for radiodensity. In scientific visualization, a maximum intensity projection ( MIP) is a method for 3D data that projects in the visualization plane the voxels with ...
Ultrasound Scans can show signs of obstruction such as hydronephrosis, while a CT scans can show the same and can locate the stricture or narrowing especially if used with contrast (CT Urogram), it can delineate other pathologies that might contribute to stricture such as Tumours or impacted stones.
