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 opportunistic screening may have tremendous potential to help patients, ACR CEO says

American College of Radiology leader Dana Smetherman, MD, MBA, discusses the new technology trend and why radiologists should be paying attention. 

Using high concentration contrast media reduces patients' pain and discomfort during injections

While most safety considerations associated with contrast injections, like hypersensitivity reactions and extravasation, rarely become reality, pain at the injection site is much more common.

Radiology experts recommend routine chest CT as ‘cost free’ method to assess other concerns in certain patients

Lung transplant recipients are at an increased risk of osteoporosis following surgery and already must undergo multiple such scans following the procedure. 

Test bolus of diluted contrast optimizes scan timing during CTA

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

AI tool detects PE missed by rads

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.
