Computed Tomography

Computed tomography (CT) is a fast and accurate imaging modality often used in emergency settings and trauma imaging. CT scans, with or without (or both) iodinated contrast are frequently used to image the brain, chest, abdomen and pelvis, but also have post-imaging reconstructive capabilities for detailed orthopedic imaging. It is now a standard imaging modality in emergency rooms to quickly assess patients. CT uses a series of X-ray images shot as the gantry rotates around the patient. Computer technology assembles these into into a dataset volume than can be slices on any access, or advanced visualization software can extract specific parts of the anatomy for study.

Providers blunt skyrocketing use of CT for pulmonary embolism, but numbers still climbing

CTPA delivery leapt 450% between 2004 and 2016, but efforts from Choosing Wisely and others may have made a dent, experts detailed in JAMA Network Open. 

Fasting before contrast-enhanced CT exams is unnecessary, experts say

In some instances, not eating solid foods can actually make patients feel sick, leading to nausea and dehydration, researchers explained recently.
