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.
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.
Non-contrast-enhanced CT scans are the gold standard for diagnosing kidney stone disease. ... number and type of scan protocol, ... abdomen and pelvis CT 9.9 [185] 12 ...
A CT pulmonary angiogram, in this case showing pulmonary embolism of saddle-type, which becomes more radiolucent than the radiocontrast filled blood surrounding it (but it may be indistinguishable without radiocontrast). Contrast CT, or contrast-enhanced computed tomography (CECT), is X-ray computed tomography (CT) using radiocontrast.
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 ...
CT cystography is performed by filling up the urinary bladder using diluted iodinated contrast to visualise any bladder injury if the subject has haematuria (blood in urine) post trauma. Since CT cystography can be done together with CT abdomen and pelvis, it has supplanted conventional cystography in such cases. [2]
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 ]
Yet, CT scan is the best alternative for diagnosing intra-abdominal injury. [1] Computed tomography provides an overall better surgical strategy planning, and possibly fewer unnecessary laparotomies. Abdominal x-ray is therefore not recommended for adults with acute abdominal pain presenting in the emergency department. [2]
