Abdominal imaging is associated with many potential uses for the different phases of contrast CT.The majority of abdominal and pelvic CT's can be performed using a single-phase, but the evaluation of some tumor types (hepatic/pancreatic/renal), the urinary collecting system, and trauma patients among others, may be best performed with multiple phases.
CT angiography is a contrast CT taken at the location and corresponding phase of the blood vessels of interest, in order to detect vascular diseases. For example, an abdominal aortic angiography is taken in the arterial phase in the abdominal level, and is useful to detect for example aortic dissection. [10]
Contrast CT is generally the initial study of choice for neck masses in adults. [39] ... Chest, abdomen and pelvis CT 9.9 [185] 12 [185] Cardiac CT angiogram 9–12 [167]
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. [1]In a CT urogram, the contrast agent is through a cannula into a vein, allowed to be cleared by the kidneys and excreted through the urinary tract as part of the urine.
Computed tomography enterography (CT enterography, CTE) is a medical imaging technique which uses computed tomography scanner and contrast media to examine the small bowel. [1] It was first introduced by Raptopoulos et al. in 1997. [ 2 ]
Diatrizoate, also known as amidotrizoate, Gastrografin, is a contrast agent used during X-ray imaging. [1] This includes visualizing veins, the urinary system, spleen, and joints, as well as computer tomography (CT scan). [1] It is given by mouth, injection into a vein, injection into the bladder, through a nasogastric tube, or rectally. [2] [3]
As with any test that screens for disease, the risks of full-body CT scans need to be weighed against the benefit of identifying a treatable disease at an early stage. [6] An alternative to a full-body CT scan may be Magnetic resonance imaging (MRI) scans. MRI scans are generally more expensive than CT but do not expose the patient to ionizing ...
Volume rendered CT scan of abdominal and pelvic blood vessels. CT angiography is a contrast CT where images are taken with a certain delay after injection of radiocontrast material. The contrast material is radiodense causing it to light up brightly within the blood vessels of interest. In order for the CT scanner to be able to scan the correct ...
