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.

Beyond just nodules—model uses all low-dose CT data to make long-term lung cancer risk predictions

New findings published in RSNA's Radiology highlight the shortcomings of using nodule characteristics and patient history alone to predict an individual’s true cancer risk.

‘Direct-to-patient’ digital prompt boosts CT lung cancer screening uptake

Researchers with two academic health systems recently tried a new approach to increase LDCT uptake, reaching patients electronically outside of a regular appointment and asking them to request a screening.

Over half of emergency CT requests are considered 'inadequate'

Up to 72% of CT requisitions from ED providers could be considered inadequate according to RI-RADS, which was developed to evaluate the clinical reasoning quality of imaging orders.

Research highlights rampant 'over-scanning' during pediatric CT exams

Experts involved in the study caution that this increases children’s risk of developing radiation-induced malignancies down the road.

How one hospital more than doubled its lung cancer screening rate

It is estimated that less than 20% of eligible patients in the U.S. adhere to LCS recommendations, despite numerous studies highlighting the exam’s effectiveness.
