PET/CT exams indicate that a coronary artery calcium (CAC) score of 0 is an accurate indicator of low coronary heart event risk -- even as a person ages, investigators have reported. A CAC score of 0 has long been accepted as a marker of very low risk of a cardiac event within the next five years, according to the group.
PET imaging with nitrogen-13 (N-13) ammonia radiotracer can help predict major adverse cardiac events in patients with ischemic heart disease (IHD), according to a study published May 30 in Radiology: Cardiothoracic Imaging. Patients underwent the scans between January 2017 and January 2021.
To make the situation more complicated, not all possible adverse events from GBCAs are noted in drug packaging, wrote a team led by Lu Wang , PhD, of Yantai Yuhuangding Hospital in Yantai, China. Adverse events occurred more frequently among women across all four drugs. Extra studies are needed to enhance the safety of GBCAs."
In an analysis of imaging among 354 patients, incidental coronary calcification on PET/CT was associated with an increased risk of major adverse cardiovascular events (MACE), according to lead author Preet Shaikh, MD, of Washington University School of Medicine in St. Among the patients, there were 98 MACE events in 74 patients (21%).

Monitor patients who have an implanted BioZorb Marker for signs of any adverse events, the FDA advised, in a December 18 notification. In addition, facilities should quarantine all products and share the notification with all surgeons who have used or plan to use the BioZorb marker, the FDA said.
The team hopes to develop a model that will not only estimate patients risk of major cardiovascular events but will inform providers on when these events may likely occur as well.
AI developer Lunit will participate in the "Saudi Vision 2030" Healthcare Sandbox, an event intended to facilitate innovation in Saudi Arabia's healthcare industry.
CT imaging shows that severe acute respiratory disease events can be caused by quantitative interstitial abnormalities (QIA) -- that is, small irregularities that don't necessarily meet diagnostic criteria for advanced pulmonary diseases but show up on CT exams over time, a study published April 30 in Radiology has reported.
This week at the International Society for Magnetic Resonance in Medicine’s annual meeting, a team of experts presented new data on the technologist’s role in MRI safety events.
Philips is recalling Tack Endovascular Systems "due to challenges experienced by customers during use, including events where additional interventions were required to retrieve or remove the Tack implant," the FDA said. The recall involves removing Tack Endovascular System from where it is used or sold and covers three versions (4F, 1.5
The Class I recall, which is the most serious recall the FDA issues, comes after numerous adverse events and complications linked to the radiographic markers were reported.

A new risk score based on SPECT imaging and other variables can accurately predict risks for women of major adverse cardiovascular events, according to a December 5 study published in Radiology: Cardiothoracic Imaging.
In a video interview at RSNA 2023, Tobias Gilk of Gilk Radiology Consultants discusses recent MRI safety incidents and shares how a new adverse event reporting system could facilitate better safety practices.
Estimating the prevalence and severity of coronary artery calcium (CAC) using data gleaned from nongated chest CT imaging improves risk assessment of postsurgical major clinical events before a patient undergoes noncardiac surgery, according to research published in the October 10 issue of Circulation. compared with 2.9%. 1 to 2 3.7%
Scottsdale, AZ-based outpatient medical imaging provider SimonMed Imaginghas confirmed that it experienced a data breach in January and will issue notices about the event to affected individuals. The company was alerted by one of its vendors of a "security incident" on January 27.
The American Investment Council hosted an event Wednesday in Charlotte, N.C., featuring a fireside chat with AIC CEO Drew Maloney and Robert L. Mittl Jr.,
The importance of quantifying coronary plaque burden has been emphasized previously because plaque burden, not stenosis, is the major predictor of risk of cardiovascular events and death," the group noted. The results were published March 4 in Radiology.
Preliminary studies have shown that permanent microspheres result in a higher rate of minor adverse events, including nerve damage, compared with temporary embolization agents, yet the studies have been limited by small numbers of patients and their safety has not been established, the researchers noted.
Although serious adverse events related to COVID-19 vaccines are rare, some are life-threatening. It is important that radiologists are aware of how these complications present.
The system combines findings from SPECT myocardial perfusion imaging with lifestyle and clinical factors to predict risk of major cardiovascular events.
"[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 risk of cardiovascular events is so low," Dewey said. years for any major adverse cardiovascular events. in the CAC score 0 group to 76.1%
Since 2020, WIRED has hosted student-led events focusing on education, skills, and community. It has also worked to coordinate themed events, journal clubs, and outreach events with medical students in Arizona, New York, Ohio, Illinois, Hawaii, Texas, Ecuador, Algeria, and India.
The reversal by the CMS to provide coverage for screening CTC beginning in January 2025 "heralds a landmark event," the authors wrote. "In But last year, the CMS backed reimbursement for screening CTC as part of the Medicare Physician Fee Schedule; the recommendation was included in the rule and went into effect in January.
"Emissions are likely to continue to increase given sustained increases in overall imaging volumes over the past decade, and the potential for further increases related to climate-change-related exposures and events," she noted.
The event will be held on Saturday, April 20 from 11 a.m. RadNet plans to host a ribbon-cutting ceremony for its MammogramNow initiative in Milford, DE, which opened in December 2023. to 3 p.m., at the Walmart Supercenter in Milford.
The event aims to build " greater awareness of the value that radiology contributes to safe patient care, and improving understanding of the vital role radiologists and radiological technologists play in the healthcare continuum," the IDoR committee said.
The society said that both winning hospitals demonstrated support for medical imaging and radiation therapy professionals by offering a team approach to patient-centered care; opportunities to earn credentials, continuing education, and advanced degrees; and the ability to be active in professional associations and local community outreach events.
They also urged radiological societies to work with disaster-response agencies to identify healthcare vulnerabilities that could result in the disruption of operations due to these kinds of events. Collaborate with industry. Work with patients.
Importantly, there were no reports of serious adverse events or notable changes in vital signs in patients one week after imaging, the group noted. Despite the limited patient data, the preliminary findings suggest that Ga-68 FZ-NR-1 is an effective tracer for identifying patients with positive nectin-4 expression, the researchers wrote.
