Is it safe to undergo FDG-PET/CT after cardiac surgery?
December 5, 2019 -- Determining when it's safe for patients to undergo FDG-PET/CT after aortic prosthetic heart valve implantation is a controversial topic. A Dutch study presented on Tuesday at RSNA 2019 found that such a scan within the first 12 months is viable.  Discuss
FDG-PET/CT has limits in esophageal cancer follow-up
November 7, 2019 -- FDG-PET/CT might be considered a double-edged sword when it comes to esophageal cancer. The modality fell short of identifying some higher tumor regression grades, but it detected interval metastases during post-treatment surveillance in a study published in the November issue of the Journal of Nuclear Medicine.  Discuss
PET/MRI illuminates cerebral vascular risk factors
November 6, 2019 -- PET/MRI scans show middle-aged adults with high vascular risk factors have less whole-brain volume by the time they reach their late 60s, but their lifestyle and physical characteristics do not influence beta-amyloid accumulation, according to a study published online on 4 November in JAMA Neurology.  Discuss
IMV: Global radiologists stay positive despite challenges
November 4, 2019 -- Radiologists in global markets are optimistic about future growth prospects for medical imaging procedures, but their priorities for imaging equipment are being dictated by local conditions. That's according to a new market research report by IMV Medical Information Division.  Discuss
German team casts doubt on PET's value in Alzheimer's
October 31, 2019 -- Researchers from a leading German facility have investigated whether a person's progression from mild cognitive impairment to Alzheimer's disease can be reliably predicted without PET imaging. Their study published online on 18 October in the Journal of Nuclear Medicine lists several nonimaging methods that can offer a better prognosis than the modality.  Discuss
Ga-68 PSMA PET/CT corrects therapy, saves money
October 9, 2019 -- Having recurrent prostate cancer patients undergo gallium-68 (Ga-68) prostate-specific membrane antigen (PSMA) PET/CT can help direct clinicians to effectual curative treatment options that also are cost effective, according to a study by German researchers published in the October issue of the Journal of Nuclear Medicine.  Discuss
Quality control tests for PET/MRI vary widely in Europe
September 30, 2019 -- A survey of eight large European imaging facilities with extensive clinical experience of PET/MRI has found wide variations in daily quality control and assurance procedures that ensure their proper function and image quality. The international study was published on 24 September in Frontiers in Physics.  Discuss
Training in FDG-PET/CT advances lung cancer outcome
September 16, 2019 -- Additional training in FDG-PET/CT to monitor concurrent chemotherapy for patients with stage III non-small cell lung cancer can significantly extend both overall and progression-free survival, according to an international study published in the October issue of European Journal of Nuclear Medicine and Molecular Imaging.  Discuss
Swiss cast new light on prostate cancer analysis
September 16, 2019 -- Researchers from Zurich have found gallium-68 prostate-specific membrane antigen offers better sensitivity, while multiparametric MRI provides better specificity, especially when determining tumor cell spread beyond the lymph node capsule or when prostate cancer extends into the seminal vesicles.  Discuss
Novel PET method advances in traumatic brain injury
September 13, 2019 -- A research team from the U.K. and Sweden has used dynamic flortaucipir-PET imaging to show that single moderate-to-severe traumatic brain injury can trigger signs of accumulation of neurodegenerative tau protein and lead to cognitive decline.  Discuss
