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.

Many CT techs unprepared to manage adverse contrast reactions
Though rare, some reactions can be life-threatening, making the understanding of how to appropriately manage them a critical aspect of a technologist's responsibilities.
Percutaneous transthoracic core needle biopsy: 3 factors that influence procedural success
A new analysis in Clinical Radiology is intended to help guide interventional radiologists in their decision-making processes regarding PCNB to reduce the likelihood of diagnostic failure.
New scanners and strategies for the ‘golden age of CCTA’
As coronary CT angiography (CCTA) continues its rapid expansion, scanner vendors are now offering more economical solutions to ensure access to imaging technology beyond premium systems most often only found at flagship hospitals and academic centers. To conquer CCTA’s technical challenges, new technologies and AI are being incorporated into a new scanner to simplify acquisition and consistently improve image quality.
Ultralow-dose CT aids in diagnosing pneumonia among immunocompromised patients
In a prospective study involving 54 adults, ultralow-dose CT, denoised with deep learning, “substantially” cut radiation exposure while accurately detecting pneumonia.

Researchers 'concerned' CT angiography topped MRA in follow-ups for pulmonary embolism

A recent study found whether a patient received MR angiography (MRA) instead of CT angiography (CTA) for a pulmonary embolism (PE) had little effect on the rate of follow-up chest CT or MRI one year later.

Non-hospital-based facilities offering cardiac imaging services a rarity in Massachusetts

In 2017, Anthem implemented a new policy that requires outpatient MR and CT scans not considered medically necessary to be completed at a freestanding imaging facility to receive coverage. This went into effect in several states, sparking its fair share of controversy along the way, and a team of Boston-based researchers wanted to know how such a policy could impact patient care in Massachusetts.

Emergency CT for head trauma may be overused

New research suggests emergency patients are often given unwarranted CT scans to check for skull fractures and brain hemorrhage, resulting in wasted healthcare dollars and increasing exposure to radiation, according to an American Roentgen Ray Society (ARRS) press release.

Treatment costs of CT-related cancers could reach $2.6 billion over 10 years

Despite the many benefits of CT imaging—early diagnosis, enhanced diagnostic accuracy, improved outcomes, etc.—a small number of cancers resulting from patient exposure to radiation from CT scans can have a big financial impact on treatment costs, according to results of a study recently presented at the annual meeting of the American Roentgen Ray Society.
