Between December 2018 and January 2021, the group enrolled 41 female participants (median age, 56 years) who underwent both PETscans. Nuclearmedicine physicians analyzed both sets of images and determined disease stages, with final stages verified via biopsy. (B) Image and caption courtesy of the RSNA.
A PET radiotracer for diagnosing Alzheimer’s disease may also be used to measure vascular brain changes in patients during PET/MRIscans, according to a study published December 7 in the Journal of NuclearMedicine. Image courtesy of the Journal of NuclearMedicine.
This persistent inflammation increases atrophy of gray matter in the brain, yet is difficult to assess on MRIscans, the authors explained. In a study published April 17 in Clinical NuclearMedicine , the group at Brigham tested a new TSPO radiotracer they developed for visualizing such activity called F-18 PBR06.
An AI algorithm designed for brain PET imaging found a glioblastoma in a patient that had gone undetected by physicians, according to a case reported February 15 in the Journal of NuclearMedicine. Baseline scan (A), segmentation results (B), and follow-up scan (C) from patient with molecular glioblastoma.
PET imaging shows different brain activity in people taking methadone or buprenorphine for opioid use disorder (OUD), according to a presentation at the recent Society of NuclearMedicine and Molecular Imaging annual meeting. They tracked serum levels of methadone or buprenorphine for the OUD subjects.
PET imaging using a newly developed radiotracer has identified different patterns of brain tau pathology over time in early-onset versus late-onset Alzheimer’s disease patients, according to a study published February 1 in the Journal of NuclearMedicine. in 15 patients with negative amyloid PETscans; 1.18 in

The findings were published in Clinical NuclearMedicine. Microglia are immune cells in the brain that are thought to have a role in MS disease progression but cannot be seen by a routine MRI. The team developed a technique called F18 PBR 06 PET imaging. One limitation to the study is the initial group was small.
iPET is AI-based software that denoises, sharpens organ boundaries, and improves resolution in PET and SPECT scans. Scans processed with the algorithm can also provide additional details by using an overlay of an MRI or CT image of the same region, the company said.
A new PETscan has shown promise in reliably detecting benign tumors in the pancreas that cannot be detected by various imaging techniques such as CT, MRI, and PETscans.
Reimbursement barriers Unfortunately, until recently, there were significant barriers to receiving amyloid PET imaging in some regions. Centers for Medicare and Medicaid Services (CMS), for example, did not cover amyloid PETscans outside of clinical trials for Medicare beneficiaries and only covered one scan per patient’s lifetime.
Brain Tumor Spotted on PET Imaging An AI algorithm named “JuST_BrainPET” identified a glioblastoma in a patient that had been missed by physicians. This finding, reported in the Journal of NuclearMedicine, underscores the potential of AI-based decision support in diagnostic and treatment planning.
MRI: This procedure offers a detailed look at the body’s soft tissues, including locations of tumors and if malignant mesothelioma has started to spread. PETScan: These scans create 3D images that offer greater insight into whether a thickened pleura or peritoneum is malignant mesothelioma or a benign condition.
PACS works as a host that integrates the radiological images acquired from different radiological imaging modalities (X-Ray, Ultrasound, CT, MRI , PETScan, NuclearMedicine, etc…) with a network of information system (RIS and or HIS), EMR, different work stations and image storage/archival system.
PET/CT imaging with a new radiotracer (F-18 PSMA-1007) is superior to MRI prior to surgery in men with intermediate-risk and high-risk prostate cancer, according to a study published on July 1 in JAMA Oncology. In this phase II clinical trial, the researchers sought to evaluate the approach further.
This standard has revolutionized the radiology industry, encompassing many imaging modalities such as X-rays, computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, nuclearmedicine, PETscans, etc.
It's only been a few years since a dedicated track in nuclearmedicine and molecular imaging was established at the meeting, and the practice already dominates it. AI studies in nuclearmedicine appear to be picking up steam as well. The system detected significantly more amyloid plaque than conventional PETscans.
