CT-FFR shows how smoking affects heart volume-to-myocardial mass ratio
Both current and former smokers show lower coronary volume-to-myocardial mass ratio (V/M) on CT fractional flow reserve (CT-FFR), researchers have found.
In a study published March 14 in Radiology: Cardiothoracic Imaging, a team led by Kenneth Holmes, MD, of St Paul's Hospital and University of British Columbia in Vancouver, Canada, reported that smoking was associated with lower coronary volume-to-myocardial mass ratio in individuals with coronary artery disease (CAD) -- results that further cement the link between smoking and heart disease.
"[We found that] current and former smoking were independently associated with ...

Coronary angiography matches IVUS in guiding PCI stent implantation
Intravascular ultrasound (IVUS) is on par with quantitative coronary angiography when it comes to guiding stent implantation, a study published March 13 in JAMA Cardiology found.
Researchers led by Cheol Whan Lee, MD, from the University of Ulsan in Seoul, South Korea, found that both methods during percutaneous coronary intervention (PCI) showed similar rates of target lesion failure at 12 months.
“Findings of this study suggest that a standardized quantitative coronary angiography-based PCI algorithm may be an acceptable alternative to IVUS-guided PCI, and warrants further research,” Lee and co-authors wrote.

CAC score may predict heart attack, stroke risk
Coronary artery calcium (CAC) scoring with CT could determine whether patients with heart disease symptoms are at low risk of heart attacks or strokes, according to a study published March 5 in Radiology.
The study results could help patients with stable chest pain avoid invasive coronary angiography (ICA), said senior author Marc Dewey, MD, of Charité - Universitätsmedizin Berlin in Germany in a statement released by the RSNA.
"[Our] findings suggest that patients with stable chest pain and a coronary artery calcium score of zero may not require invasive coronary angiography using cardiac catheterization because the r...

ECR: 3 tips for developing a successful cardiac imaging practice
VIENNA -- It's definitely possible to develop a successful cardiac imaging practice, according to a professional development presentation delivered February 28 at the ECR in Vienna.
It all comes down to a willingness to learn and to collaborate with colleagues across specialties, session chair and first presenter Dr. Matthias Gutberlet, PhD, of the University of Leipzig in Germany, told session attendees.
"Teamwork is the key to success," he said.
Gutberlet described how he came to cardiac imaging early in his medical career. At the time, there was little training for, say, cardiac MRI. But he persevered.
"Imaging was ...

CT may be preferred over ICA for younger cardiac patients
CT could be the preferred method for younger patients in cardiac outcomes related to major procedure-related complications, according to research published February 28 in JAMA Cardiology.
A team led by the DISCHARGE Trial Group found that while age does change the effect of CT and invasive coronary angiography (ICA) on the outcome of major adverse cardiovascular events (MACE), it does modify the effect of these techniques on major procedure-related complications. The team reported that CT is tied to a lower risk of major procedure-related complications in younger patients.
“The findings emphasize the importance of furt...

PCCT improves assessment of coronary artery disease
Ultrahigh-spatial-resolution photon-counting detector CT (PCCT) improves the evaluation of coronary artery disease (CAD) -- enabling the reclassification of disease to a lower category in 54% of patients, researchers have found.
The technology could improve patient management and reduce unnecessary interventions, according to a team that included corresponding author Tilman Emrich, MD, of the Medical University of South Carolina in Charleston. The findings were published February 20 in Radiology.

Coding changes that will impact radiology practices in 2024
Erin Stephens.The annual update to the Current Procedural Terminology1 (CPT) for 2024 has 230 new codes, 70 revised codes, and 49 deleted codes. In addition, there are 395 new diagnosis codes contained in the ICD-10-CM2 update, about one-third of them describing new ways to capture accidents and injuries. Although relatively few of these changes will impact radiology practices, it’s essential to know what they are and adjust your practice systems accordingly.

Music calms patients undergoing imaging procedures
Music can be calming for patients undergoing medical imaging, an article published February 7 in Radiography suggests.
A team led by Lina Viera, PhD, from the Lisbon Polytechnic Institute in Portugal found that musical interventions, whether they be classical songs or sounds of nature, can reduce anxiety and heart rate outcomes in patients. This includes imaging procedures such as MRI, mammography, and PET among others.
“Musical intervention arises as a painless, reliable, low-cost, and side-effect-free strategy, presenting imaging departments with a practical means to enhance patient comfort and mitigate anxiety and s...

AI boosts CTPA's ability to predict lung disease survival
The percentage of lung fibrosis quantified on CT pulmonary angiograms (CTPA) by an AI model is associated with increased risk of mortality -- and boosts clinicians' ability to predict the survival of lung disease patients, researchers have found.
The information is especially useful when used in combination with radiologic severity scoring -- compared with radiologic scoring alone -- and the study findings could help clinicians better care for their patients, wrote a team led by Krit Dwivedi, PhD, of the University of Sheffield in England. The results were published February 6 in Radiology.

EVT improves outcomes in stroke patients
Endovascular thrombectomy (EVT) may improve outcomes in stroke patients compared to medical management – importantly, even when imaging suggests varying ranges of brain injury, according to a study published February 7 in JAMA.
In a clinical trial, EVT improved clinical outcomes after 90 days in patients with a wide spectrum of infarct volumes (stroke sizes) assessed either by CT or MRI imaging at baseline, noted a group led by Amrou Sarraj, MD, of Case Western Reserve University in Cleveland, OH.
“EVT treatment effects and outcomes may differ by imaging selection modalities and are not well characterized in patients...

Use CT first to triage chest pain patients for revascularization
A "CT first" strategy is an effective way to determine if patients with stable chest pain need revascularization with invasive coronary angiography (ICA), researchers have found.
