Experts: Consider BMI when imaging patients with chest pain
A patient’s body mass index (BMI) has a significant effect on how much radiation exposure they receive from chest imaging in cases of suspected cardiac ischemia, according to a study published April 9 in the Journal of the American Heart Association.
Cardiologists at Saint Luke's Mid America Heart Institute in Kansas City, MO, found that as BMI increases, so too does radiation exposure, although PET offers the least variability, followed by SPECT, and then coronary CT angiography (CCTA). The finding is key to providing “patient-centered” care, the group wrote.
“These data may be helpful to generate more accurate ...

SPECT/CT algorithm predicts heart failure hospitalizations
This study represents the first evidence, to our knowledge, demonstrating that integrating SPECT MPI into an AI-based risk assessment algorithm significantly improves the prediction of hospitalizations due to [heart failure],” the group wrote. The research was published March 28 in the Journal of Nuclear Medicine.Heart failure is a major cause of morbidity and mortality in the United States and worldwide, with prevalence projected to increase by almost 50% from 2012 to 2030, the authors wrote. They noted that identifying patients who are at risk for heart failure exacerbation can open opportunities for prevention strateg...

Can cardiac PET/CT ‘revolutionize’ heart care?
PET/CT is poised to become a key tool for imaging the coronary arteries – a clinical imaging exam that can reveal early warning signs of fatal conditions when patients present with symptoms of chest pain, experts say.
The “hybrid” scan – which combines molecular PET and anatomical CT images – may have its highest potential in visualizing early signs of so-called “perfusion deficits” (regions of obstructed blood flow), said Marcelo Di Carli, MD, a professor of radiology and medicine at Harvard Medical School, in a recent interview with AuntMinnie.com.
“[PET/CT] helps us differentiate a patient who has ches...

RSNA calls out toxicity concerns with theranostics
While recent evidence suggests that theranostic agents may be more effective when used earlier for prostate cancer patients, experts recommend proceeding conservatively with theranostic treatments until more is known about dose limits, according to an article published March 21 by the RSNA.
Data from theranostics is starting to focus on radiation dosimetry and dose limits in relation to kidney and other organ damage, said Nadine Mallak, MD, associate professor of body imaging and nuclear medicine at Oregon Health and Science University in Portland.
The article points out that compared with external beam radiation therapy...

Groups aim to standardize nuclear medicine imaging of CV infections
Eleven medical associations have released guidance on the use of PET/CT and SPECT/CT for patients with cardiovascular (CV) infections.
The recommendations could improve patient care, as current clinical tools are often insufficient in complicated cases, noted lead author of the guidance Jamieson Bourque, MD, of the University of Virginia Health System in Charlottesville. The document was published jointly March 11 in the Journal of Nuclear Cardiology, Clinical Infectious Diseases, the Heart Rhythm Journal, and JACC: Cardiovascular Imaging.
“The stakes are high with cardiovascular infection because the incidence is incr...

Is ‘theragnomics’ the future in molecular imaging?
Combining theranostics and radiomics – a new concept termed “theragnomics” – could be the key to realizing the full potential of molecular imaging of cancer patients, according to a presentation delivered February 28 at ECR 2024.
Desiree Deandreis, MD, of Gustave Roussy Cancer Treatment Center in Villejuif, France, described the concept and noted that its goal is to harness imaging power to improve patient selection for treatment, identify how patients respond to therapy, integrate new prognostic biomarkers, and ultimately improve the efficacy of new treatments.
“My question is all the ways we can shift from a ...

FDA issues recall for Philips SPECT scanner
The U.S. Food and Drug Administration (FDA) has issued a Class I recall for Philips' BrightView SPECT scanners due to a potential component failure that could result in injury to patients.
“If the detector is positioned below center of gantry, there is a potential for abrasion, contusion, laceration, and/or fracture to the patient's lower limbs, as well as an interruption to normal system operation. If detector is positioned above center of gantry, there may be an interruption to normal system operation,” the FDA said, in its recall notice.
Philips notified customers of the potential problem on December 15, 2023, wit...

Nonhospital sites see increased competition for oncology-related imaging
Davin Korstjens.In 2023, nonhospital sites faced more competition compared with hospital-based facilities for oncology-related diagnostic imaging scans, according to IMV’s recently published 2023 Oncology in Diagnostic Imaging Market Outlook Report.
For the future outlook factor “Competition with other imaging providers in our area is reducing the number of oncology-related patients scanned at our facility," nonhospital sites gave a 3.2 out of 5 rating (with 5 indicating very high importance) compared with a 2.7 out of 5 rating for hospital sites – results that indicate nonhospital sites face more competition for on...
