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.

FDA greenlights intracranial hemorrhage AI

RapidAI has been cleared for U.S. marketing of updated AI-outfitted software that quickly detects or rules out acute brain hemorrhage on unenhanced CT.

James Udelson, MD, from Tufts and an investiogator in the PRECISE trial, explains how FFR-CT combined with coronary CT outperformed the standard of care in patients with stable chest pain, or low-risk patients with suspected coronary involvement.

Neuroimaging recedes behind other cost compilers in stroke care

Contrary to older research that showed neuroimaging emerging as the single most dominating cost contributor in ischemic stroke care for older Americans, a new study shows treatment and other line items account for bigger slices of the bill.

The fall and rise of trauma CT on the front and back of COVID-19

When COVID-19 social-distancing orders eased across a densely populated county in the southwest, trauma visits spiked 35% over the pre-pandemic normal. This was accompanied by a 17% increase in average daily trauma CT exams.

A GE Revolution CT system on display at the 2022 Society of cardiovascular Computed Tomography (SCCT) meeting is an example of the types of the systems being sought in the U.S. and Western Europe replacement CT market. It features AI enhanced features to automate protocol and help reduce dose, 160 mm of anatomical coverage per rotation and offers spectral imaging using fast kV switching between different energies during one scan.

14 House members—7 Democrat, 7 Republican—press CMS to step up its game on CCTA

A bipartisan group in the U.S. House is asking CMS to acknowledge the cost-effectiveness of coronary CT angiography by comprehensively covering the exam for patients who present with acute but stable chest pain or other early signs of arterial plaque buildup.

Ricardo Cury, MD, MBA, MSCCT, chairman of radiology, direct of cardiac imaging, Baptist Health South Florida and Miami Cardiac and Vascular Institute, discusses the new CAD-RADS 2.0 cardiac imaging reporting criteria at the 2022 SCCT meeting. Interview with Radiology Business Editor Dave Fornell.

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.

The all-in-one Omni Legend PET/CT scanner is now being manufactured in a new production facility in Waukesha, Wisconsin.
