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.

HeartFlow's RoadMap technology where AI reads the image in a first pass to highlight areas of interest with for the radiologist or cardiologist on coronary CT scan. The technology was shown to reduce reading time by 25%.

Three studies show value of AI to speed cardiac CT reads and soft plaque evaluation 

AI to help interpret cardiac CT was shown to reduce exam read times to improve workflow efficiency, and improve patient diagnostics with additional information on soft plaques. Data was presented in three HeartFlow AI technology studies at SCCT 2023.

The good and the bad of synoptic radiology reports

Synoptic radiology reports with detailed information on disease sites in ovarian cancer could help to guide surgical decisions, but they can come at a cost.

SPECT/CT helps personalize treatment options for prostate cancer patients

Using SPECT/CT imaging, providers can stratify patients based on their treatment responses and make personalized adjustments accordingly.

Syringeless contrast media injectors like the GE Ulrich CT Motion have gained a lot of interest in 2022 because of the iodine contrast shortage. These systems use rollers to squeeze precise amounts of contrast from a large bolus container for multiple patients, helping conserve a significant amount of contrast.

Multi-use syringeless injectors could completely eliminate contrast waste

Such products could increase departmental efficiency and advance environmental initiatives in radiology, experts claimed in Academic Radiology.

MRA for pulmonary embolus

MR angiography a suitable alternative to CT when ruling out pulmonary embolus

The modality switch became especially important during the iodinated contrast shortage of 2022 when clinics were forced to deploy mitigation tactics as a means of preserving their contrast supply.

Photon-counting technology offers new opportunities in imaging high-risk CAD patients

Coronary CT angiography is commonly used to assess patients at low or intermediate risk of CAD but is less effective in high-risk patients with an increased presence of coronary calcifications and stents due to the “blooming” effect they have on imaging.

COVID causes increase risk of clotting. Example of a pulmonary embolism. CT pulmonary angiograms in a 77-year-old man with COVID-19 and a saddle embolus to pulmonary arteries (black arrow in A) extending into right and left pulmonary arteries (white arrows) in (A, B) axial and (C) coronal planes. Arrowheads show pulmonary changes associated with COVID-19 and possible lung infarction (black arrow in C). (D) Axial image at the level of the ventricles shows right-sided heart strain. RSNA.

'Concerning' CT findings may lead to unnecessary hospitalization in PE patients

CT findings that have historically been deemed as concerning relative to PE might not hold as much weight when it comes to associated risks as previously thought, new analysis suggests.

AI primed for pulmonary nodule detection in adults, falls short in pediatric population

Artificial intelligence tools have proven to be beneficial in detecting pulmonary nodules on chest CTs of adults, but less is known about their utility in pediatric populations.

Positron, a New York-based nuclear imaging company, will now provide Upbeat Cardiology Solutions with advanced PET/CT systems and services. 

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.
