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.

Software glitch triggers FDA recall of nearly 2,000 GE SPECT and CT systems
According to the notification, the issue can cause the scanners to inadvertently move during imaging.
Shared decision-making visits significantly boost CT lung cancer screening adherence
SDM "is more than just a billing requirement—it’s a valuable opportunity to engage patients," says radiologist Farouk Dako, MD, MPH.
AI enables tracking of coronary artery calcium growth on routine lung cancer CT scans
New data suggest increases in CAC scores between lung cancer screenings strongly correlates with the risk of adverse cardiovascular events.
New AI tool outperforms humans at lung tumor segmentation
The iSeg platform has the potential to significantly improve tumor segmentation processes prior to radiation therapy treatment.
FDA issues recall on Philips spectral CT systems
A software issue could lead to the affected devices inadvertently moving, potentially making unintentional contact with patients or other equipment, according to the FDA.

Bolus tracking with individualized delays for abdominal multiphase CT beats fixed delay protocols

Current bolus tracking technology remains limited by the fixed delay before the start of a scan, experts explained in the European Journal of Radiology.

For first time, large population-based study proves CT screening reduces lung cancer deaths

The findings are based on an analysis of more than 300,000 patients diagnosed with non-small lung cancer between 2006-2016.

First clinical photon-counting CT tops past 50 years of technology, with ‘striking’ improvements

The FDA-cleared machine reduced noise by up to 47% and offers new information that can change patient management, Mayo Clinic experts said.

‘One-stop shop’ CT protocol boosts definitive diagnostic rates in patients with acute chest pain

The comprehensive approach yields crucial information usually obtained via CT and MRI, which can cut time to diagnosis, experts explained.

COVID-19 disruptions lead to ‘substantial’ reductions in new cancer diagnosed via CT, other methods

Health systems must identify areas where patients are not following up on routine screening and find ways to reassure and reengage them, experts charged.

Body CT scans detect infection areas among ICU patients with sepsis

While guidelines stress the importance of quickly eradicating the underlying source of infection, data on the best imaging strategy remains lacking, researchers reported.

RSNA21: Deep learning automatically labels coronary arteries to produce structured CCTA reports

The algorithm yielded a 94.4% accuracy for labeling arteries in accordance with the Society of Cardiovascular Computed Tomography guidelines.

AI performs well when detecting intracranial hemorrhage on brain CT, but further research is ‘critical’

Experts cited positive findings but stopped short of recommending convolutional neural networks as the go-to standard of care for detecting ICH.
