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.

CCTA will play an essential role in the cath labs of the future
Noninvasive coronary CT angiography is growing more and more important as time goes on, helping cardiologists make critical treatment decisions. Carlos Collet, MD, PhD, discussed the technique's potential to be a real game-changer for patient care in a new interview.
Significant variability found in pediatric CT imaging interpretations
Such discordance between pediatric and general radiologists could result in care delays and treatment changes.
AI bests radiologists at predicting lung cancer treatment responses
More accurate response assessments could give providers an opportunity to proactively manage treatment decisions in the future.
FDA clears AI solution for identifying large vessel occlusions on CTA
If left untreated, LVOs can cause ischemic strokes. The algorithm has the potential to significantly reduce time to treatment in these emergency scenarios.
Beyond just nodules—model uses all low-dose CT data to make long-term lung cancer risk predictions
New findings published in RSNA's Radiology highlight the shortcomings of using nodule characteristics and patient history alone to predict an individual’s true cancer risk.

Fat attenuation index (FAI) CT imaging of coronary artery fat can show inflammation and can help pin-point vulnerable plaques, or show the reversal of inflammation due to drug therapies. The technology is being developed by the vendor Caristo, which has European CE mark and the company is seeking FDA clearance. #SCCT #SCCT2022

Ron Blankstein, MD, Brigham and Women's Hospital, explains recent advances in coronary computed tomography angiography (CCTA) technology.

radiology reporting EHR health record CDS AUC

EHR-based solutions to the iodinated contrast shortage reduce usage by 12%

This week in AJR, experts from a large, multisite health system detailed their efforts to preserve contrast supplies by implementing electronic health record (EHR) order entry-based interventions.

Cardiac CT now in the spotlight thanks to chest pain guidelines

With the elevation of cardiac CT to a 1A indication in the 2021 Chest Pain Guidelines, there has been a large amount of interest in starting coronary artery CT angiography (CCTA) programs.

VIDEO: 3 challenges for Society of Cardiovascular Computed Tomography members in 2023

Society of Cardiovascular Computed Tomography (SCCT) President Brian Ghoshhajra, MD, detailed three challenges he is making to SCCT members in the coming year.

For prostate cancer diagnostics, 7T MRI has next to nothing on ultrasound tomography

In an initial comparison study involving 10 patients with high-risk prostate cancer, ultrasound tomography (UT) soundly beat 7-Tesla multiparametric MRI on detection sensitivity, 85.7% to 65.3%.

$30K up for grabs in new AI challenge from RSNA

Americans suffer more than 1 million fractured vertebrae every year. RSNA’s latest AI competition may help advance precision detection and classification of this unfortunately common source of pain and potential debilitation.

Noteworthy FDA approvals of the week: Ceiling-mounted CT angiography, AI for brain-adjacent bleeds

Two companies serving medical imagers just had products cleared for marketing in the U.S.

Ron Blankstein, MD, MSCCT, associate director, cardiovascular imaging program, director, cardiac computed tomography, Brigham and Women's Hospital, and professor of medicine, Harvard Medical School, was a co-author on the ACC 2021 Chest Pain Guidelines,[1] which now lists coronary computed tomography angiography (CCTA or CTA) as a 1A level recommendation for front line imaging. He gave an overview of the guidelines during the 2022 Society of Cardiovascular CT (SCCT) meeting in July. #SCCT2022
