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.

Syringeless contrast media injectors like the GE Ulrich CT Motion gained a lot of interest in 2022 because of the iodinated contrast shortage. These systems use rollers to squeeze precise amounts of contrast from a large bolus container for multiple patients, helping conserve a significant amount of contrast.

Multi-use syringeless injectors could completely eliminate contrast waste

Such products could increase departmental efficiency and advance environmental initiatives in radiology, experts claimed in Academic Radiology.
