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.

Alcohol use doubles risk of intracranial hemorrhage after falls in older adults, CT data show

And the more often those among this group drink, the greater their odds are of sustaining a brain bleed, new research suggests.

'One-stop-shop' CT stroke protocol reduces scan time, contrast dose and radiation exposure

The protocol integrates CT angiography of the head and neck with the tomography perfusion acquisition, eliminating the need for two separate scans.

American College of Radiology (ACR) CEO Dana H. Smetherman, MD, MPH, MBA, FACR, explains why opportunistic screening is an important AI imaging technology trend radiology practices should be paying attention.

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.

Automated CT-derived markers identify those at higher risk of developing diabetes and other conditions

These measures could be utilized as an opportunistic screening tool in individuals who undergo routine health screenings.

Test bolus of diluted contrast optimizes scan timing during CTA

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

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 newly cleared offering, AutoChamber, was designed with opportunistic screening in mind. It can evaluate many different kinds of CT images, including those originally gathered to screen patients for lung cancer.
