Molecular Imaging

A novel radiotracer tested for the first time in humans may help improve the detection of primary and metastatic melanoma, a highly aggressive form of skin cancer, according to a study published in the January issue of the Journal of Nuclear Medicine.

Radiolabeled 18F-fluoride PET/CT proved superior at detecting bone metastases (BM) than a comparative radiotracer, according to a Jan. 14 study published in Clinical Radiology.

Breast-specific gamma imaging (BSGI) outperformed breast MRI in predicting a complete pathologic response to neoadjuvant chemotherapy (NAC) with breast cancer, according to research published online Jan. 8 in the American Journal of Roentgenology.

The findings suggest the evaluation of molecular biomarkers for Alzheimer’s disease should be adjusted for race, as African American patients were found to have lower levels of tau—a key biomarker used to identify the disease, according to research published online Jan. 7 in JAMA Neurology.

A team of Dutch researchers has developed a real-time hybrid fluoroscopic and nuclear imaging detector that may aid interventional radiology (IR) procedures such as radioembolization, according to authors of a Jan. 8 study published in Radiology.

A team of researchers from the University of Illinois at Urbana-Champaign has developed a portable optical imaging system that can visualize molecular features of breast tissue after it's been surgically removed from a patient, according to research published Dec. 19 in Science Advances.

PSMA PET/CT detected more lesions in patients with prostate cancer and resulted in more changes in management than CT alone when utilized prior to radiotherapy, reported authors of a Dec. 14 study in the Journal of Nuclear Medicine.

The new platform—which can automatically detect motile parasites in bodily fluids and analyze more than three milliliters of a bodily fluid sample in 20 minutes—provides images clearer than those from traditional optical microscopy, according to research published online Dec. 12 in the journal Light: Science & Applications.

In patients with prostate cancer, accurate primary staging is important for developing a treatment strategy. A study published in the December issue of the Journal of Nuclear Medicine found whole-body PET/MRI may offer a “one-stop-shop” to do so.

The Washington University School of Medicine in St. Louis (WUSTL) was awarded a five-year, $6.3 million grant to establish a new research center to develop and test novel PET tracers.

Artificial intelligence (AI) can generate high-quality amyloid PET images from simultaneously acquired MR images and ultra-low-dose PET data, according to a Dec. 11 study published in Radiology.

PET imaging may hold promise for personalizing treatment in patients with tuberculosis meningitis (TBM), a rare disease that leaves some survivors with permanent brain damage, reported researchers from Johns Hopkins University School of Medicine in Baltimore.
