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.

AI model nearly halves false positive rates for lung cancer CT screenings
Reducing false positives could decrease the frequency of unnecessary procedures, lower the associated costs and also ease patient anxiety concerning CT results.
ED pivots to virtual radiology service, slashing CT turnaround times and lengths of stay
Syracuse, New York-based Upstate Medical University had previously relied on rad residents to handle initial reads, with attendings finalizing interpretation in the a.m.
Medicare proposal eliminates plan to make CT radiation-related quality measure mandatory in 2027
The measure evaluates the proportion of scans that exceed certain thresholds for image noise or radiation dose across 18 categories.
Emphysema on baseline lung cancer CT a sign of future mortality risk
“Lung cancer screening shouldn’t just be looking for nodules. That’s a small part of what we see on the CT scan.”
FDA clears GE Revolution Vibe CT scanner aimed at rapidly growing CCTA market
“FDA clearance comes at the perfect time, with guidelines being adopted clinically for cardiac CT and with positive reimbursement driving procedure growth," says Jean-Luc Procaccini, CEO, molecular imaging and CT.

New type of PET/CT scan could change how hypertension is diagnosed and treated

The 10-minute scan can “light up” aldosterone-producing nodules in the adrenal glands following an injection of metomidate—a radioactive dye that binds specifically to aldosterone-producing nodules.

New research discourages use of advanced vascular imaging in trauma patients

Experts argue that the overall incidence of blunt cerebrovascular injury is very low and that symptomatic vascular injuries in these cases are even lower.

AI tool predicts lung cancer without radiologists or clinical histories

The deep learning model was trained to predict risk of lung cancer in the one to six years following completion of an LDCT scan, and it does not require clinical information relative to risk factors to do so.

Number of kids needing sedation prior to imaging drastically drops following intervention

At one institution, the intervention resulted in an average cost savings of $139,367.80 per year.

Paleo-radiologist: ‘I saw the king’s face for the first time’

Thanks to a radiologist equipped with CT and 3D image reconstruction, Pharaoh Amenhotep I is finally getting a proper clinical workup.

Radiology trainees win over trauma surgeons with immediate reads

When trained with high-fidelity simulation, junior radiology residents can master the discipline of reading whole-body CTs right at the trauma scanner—and doing so with high diagnostic accuracy, work speed and interpretive confidence.

Subtraction boosts CCTA accuracy, even in the presence of extensive calcium

Researchers recently found results yielded via subtraction CCTA to be similar to those produced by ICA in assessing stenosis grading.
