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.

Neuroimaging not necessary for all patients who present to ED with vertigo
The decision to utilize such scans is challenging for emergency providers, with the condition most often of benign origin, according to new research published in the journal of Emergency Radiology.
AI reduces readers' kidney lesion interpretation times by over 30%
The tool also can be used on contrasted abdominal scans completed for other clinical indications, addressing suspicious lesions before they worsen.
Majority of residents' after-hours CT report discrepancies not clinically significant
A new analysis published in Emergency Radiology examines how likely it is for these discrepancies to lead to changes in diagnosis and patient care.
Dual-energy CT systems allow for significant reduction in contrast dose
DECT systems allow for a contrast dose reduction of up to 25% during computed tomography pulmonary angiography exams.
AI-powered FFR-CT software linked to considerable cost savings, accurate predictions
According to Heartflow, its AI offering saves health systems nearly $1,400 per patient thanks to reductions in unnecessary cardiovascular testing.

Reimbursement expected to drive implementation of CCTA, coronary plaque analysis

For years, imaging experts have predicted that CCTA may become the primary imaging modality for coronary artery disease and eliminate the need for invasive diagnostic catheterizations. That prediction is now coming true.
