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.

New data highlight how Heartflow's AI software drives major shifts in heart care
One of the study's most significant findings was that patients managed using the advanced AI software saw LDL cholesterol drops of 18.7 mg/dL, with a 15% reduction in their risk of a cardiac event. Even patients with no calcified plaque saw significant changes in care management.
Bipartisan lawmakers seek to increase funding for mobile CT lung cancer screening
The Mobile Cancer Screening Act would offer grants to help imaging providers purchase mobile CT screening units through the federal government.
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.

Test bolus of diluted contrast optimizes scan timing during CTA

It also reduces iodine uptake and radiation dose in patients, without sacrificing image quality.

Commercially available AI tool detects 76% of PE that rads initially missed on CT

Improving the detection of pulmonary embolism has been a popular target among multiple AI vendors.

COVID-19 survivors with diabetes may require long-term lung monitoring

Three years after recovery, individuals with diabetes had higher incidence of respiratory symptoms, lung abnormalities on CT scans, and problems moving oxygen into the blood.

CT colonography utilization has doubled over the last decade

That number is expected to grow even more in the coming years, as the exam serves as a noninvasive alternative to colonoscopy, while also providing more accurate results than stool tests.

The imaging iodine contrast shortage is delaying procedures and causing rationing at hospitals. impact is it having on hospitals and the tough decisions that are being made to triage patients to determine if they will get a contrast CT scan or an interventional or surgical procedure requiring contrast.

Higher radiation doses don't always improve CT image quality

Dose reduction protocols vary across scanners and organizations. This can create inconsistencies in both image quality and measuring patients’ total radiation exposure.

CT guided bone marrow biopsies cost 13 times more than non-image guided procedures, without improving specimen quality

A new analysis offers a thorough overview of the factors that influence providers’ decision to utilize image guidance and how they affect expenditures.

CT scan of a Coca-Cola bottle rectal foreign body. There are a sizable number of emergency room cases each year for items people insert into their rectums that become lodged or lost inside the colon. This includes many types of household items beyond vibrators and commercially made butt plugs. Ghonaim E, Rectal foreign body. Case study, Radiopaedia.org.

PHOTO GALLERY: Abdominal, pelvic and rectal foreign bodies

This is a clinical photo gallery showcasing the uncommon findings of foreign bodies in pelvic and abdominal CT and X-ray, often from emergency room visits.

HeartFlow introduced its next generation artificial intelligence (AI) Plaque Analysis with an interactive experience at SCCT 2024. It shows a 3D plaque model and analysis by territory across calcified, non-calcified and low-attenuation plaques. This includes viewing cross-sectional, color-coded images of each plaque type where it was quantified along the vessel. #SCCT #SCCT24 #SCCT2024

Updated HeartFlow technology offers interactive features, full integration with FFR-CT

HeartFlow is using SCCT 2024 to introduce the world to its updated Plaque Analysis platform. “Accurately diagnosing a patient’s risk for coronary artery disease is critical for determining the best treatment," Chief Medical Officer Campbell Rogers, MD, explained.
