Study: Reduced PET Tracer, More Scans
2015 03 Nov
Latest advances in PET scanning technology make it possible to reduce radiation dose for both patients and medical staff by up to 30 percent, allowing an addition of 100 scans a year at Central Manchester University Hospitals. A recent study by scientists at Central Manchester University Hospitals NHS Foundation Trust and The University of Manchester... Read more
Multimodality Imaging of the Heart: Is More Better?
2015 04 Oct
In most patients who are referred for work-up of suspected or known coronary artery disease (CAD) by non-invasive cardiac imaging, one single imaging technique is often adequate, according to an article appearing in the journal Cor et Vasa , published by the Czech Society of Cardiology. For instance, MRI is able to provide information about morphology... Read more
Full-Body PET Scan Can Detect Blood Clots: Animal Study
2015 21 Sep
A new radiopharmaceutical probe developed at Massachusetts General Hospital (MGH) has allowed researchers to perform full-body scans to locate hidden blood clots in an animal model, according to a report that will appear in the October issue of the journal Arteriosclerosis, Thrombosis and Vascular Biology . Finding the location and composition of clots... Read more
Oesophageal Cancer: PET Does Not Improve Treatment
2015 08 Sep
Positron emission tomography (PET) is increasingly being used to assess the effectiveness of chemo- or radiotherapy in patients with cancer of the oesophagus. Now researchers say that no robust evidence exists to show that PET improves the treatment for these patients. Their finding is reported in the journal Deutsches Ärzteblatt International . Cancer...

PET Imaging Detects Fast-growing Prostate Cancer
2015 25 Aug
A Johns Hopkins-led study shows that PET imaging with a specific biomarker could detect fast-growing primary prostate cancer and distinguish it from benign prostate lesions. The finding, reported in The Journal of Nuclear Medicine , is important for patients with suspected prostate cancer that has not been confirmed by standard biopsy. The study... Read more
PET Method Scans Whole Body for a Blood Clot
2015 20 Aug
A new imaging method — so far tested in rats — may someday enable clinicians to quickly scan the entire body for a blood clot, according to researchers from the Martinos Center for Biomedical Imaging at Massachusetts General Hospital. The study was presented at the 250th National Meeting & Exposition of the American Chemical Society (ACS), held on 16-20... Read more
Insulin Resistance Increases Risk for Alzheimer's Disease
2015 28 Jul
An imaging study finds a strong association between insulin resistance and lower brain glucose metabolism in a group of late middle-age adults at risk for Alzheimer's disease (AD). The findings are published online in JAMA Neurology. Insulin resistance, broadly defined as reduced tissue responsiveness to the action of insulin, is common in people who... Read more
Hybrid Scanner Uses Multiple Imaging Techniques
2015 06 Jul
Scientists are developing a new molecular, preclinical hybrid imaging system that combines positron emission tomography (PET) and MRI, and can help experts to find new drugs and advance imaging research. The new scanner includes a window for tissue observation, and an imaging chamber. The hybrid scanner, presented at the 2015 Annual Meeting of the... Read more
Novel PET Tracer Pinpoints Risky Blood Clots
2015 11 Jun
Researchers have developed a molecular imaging technique that could save lives by revealing troublesome thrombi, or blood clots. Their work was presented at the 2015 annual meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI). "Thrombosis is the underlying cause of deadly diseases such as stroke, pulmonary embolism, deep vein... Read more
PET Scan after Chemo Could Avoid Need for Radiotherapy
2015 23 Apr
A positron-emission tomography (PET) scan immediately after treatment with chemotherapy can identify patients who have a very good outcome without additional radiotherapy, according to a study published in the New England Journal of Medicine . The "RAPID" trial involved 602 Hodgkin lymphoma patients who had a PET scan performed after their chemotherapy.... Read more
