PET/MRI shows inflammation link to mitral valve prolapse
Researchers using a hybrid PET/MRI scanner detected a link between degenerative mitral valve prolapse and F-18 FDG uptake, a surrogate for myocardial inflammation and/or ischemia. The results, published online May 27 in JAMA Cardiology, apply to asymptomatic patients as well, suggesting an ongoing subclinical disease process.

Screening reduces risk of breast cancer death by 41%
Mammography screening reduces the risk of dying of breast cancer by 41% within 10 years of diagnosis, according to a study published May 11 in Cancer. The study attributes most of the mortality reduction to the impact of screening rather than advances in breast cancer therapy.

Life after COVID-19 requires assessment, logistical planning
As radiology departments plan their return to normalcy after the COVID-19 pandemic, they must balance clinical assessment, ethical judgment, and logistical planning, stated U.S. and Irish radiologists in an article published May 4 in the Journal of the American College of Radiology.

Model predicts metastases in endometrial cancer patients
Using ultrasound in combination with endometrial biopsy results and clinical characteristics allows clinicians to reliably predict the risk of lymph node metastases in endometrial cancer patients before surgery. Researchers found the model to be superior to risk stratification alone in a study published online December 16 in Ultrasound in Obstetrics and Gynecology.

Long-term breast cancer survivors die from other diseases
Women who live more than 10 years after a diagnosis of breast cancer are more likely to die of diseases other than cancer, such as heart and cerebrovascular diseases, according to a large study published online on December 16 in Cancer. Researchers attribute the finding to improved therapies that are enabling women to survive longer.

Biopsy protocol rules out surgery for women after chemo
Vacuum-assisted image-guided breast biopsy can reliably predict which breast cancer patients treated with chemotherapy have responded well enough that follow-up surgery is not required to remove residual cancer, according to a December 13 presentation at the 2019 San Antonio Breast Cancer Symposium.

FFDM may beat analog and CR for breast cancer screening
Full-field digital mammography (FFDM) detects breast cancer better than either analog film-screen mammography or computed radiography (CR), regardless of age, breast density, or screening round, according to a South Korean retrospective study of over 8 million women published online on December 3 in Radiology.

Add MRI to breast screening for fewer interval cancers
In a large Dutch study, using supplemental MRI screening in women with extremely dense breast tissue and normal mammograms resulted in significantly fewer interval cancers than using mammography alone.

Breast ultrasound spots more cancers in dense breasts
With proper training and experience, breast ultrasound consistently improves detection of node-negative invasive cancer in women with dense breasts on mammography, according to a literature review in the Journal of Breast Imaging. Similar results have been observed after digital breast tomosynthesis.

How does F-18 flurpiridaz PET perform in routine clinical practice?
By Will Morton
A study provides real-world insights into the clinical implementation of F-18 flurpiridaz PET in a diverse group.
January 26, 2026
Ischemia in the circumflex territory. F-18 flurpiridaz PET showed a perfusion defect in the lateral wall during pharmacological stress, which improved in rest. Myocardial blood flow (MBF) quantification showed decreased MBFstress (1.4 mL/min/g) and myocardial flow reserve (MFR) (2.2) in the circumflex (Cx) territory, with adequate flow in the left anterior descending and right coronary artery territories, MBFstress 2.6 and 2.2 mL/min/g, and MFR 3.4 and 3.1, respectively. Coronary angiography showed a 70%-99% stenosis in the Cx artery, for which percutaneous coronary intervention was performed with good result and good clinical outcome.
