PET shows tau better predicts brain atrophy than amyloid
January 3, 2020 -- PET scans comparing the location and magnitude of tau protein accumulation have shown that tau better predicts future brain atrophy in patients with Alzheimer's disease compared with amyloid deposition -- and a year or more in advance, according to a study published online January 1 in Science Translational Medicine.  Discuss
Does thyroid cancer screening lead to overdiagnosis?
December 23, 2019 -- Two studies from the U.S. and South Korea are raising questions about the role of ultrasound screening and thyroid cancer incidence. Researchers specifically address the issue of overdiagnosis in studies published in the December 24/31 issue of the Journal of the American Medical Association.  Discuss
Patients at risk for NSF might be safe with certain GBCAs
December 20, 2019 -- Could certain gadolinium-based contrast agents (GBCAs) be safe for patients undergoing an MRI scan whose stage 4 or 5 chronic kidney disease puts them at risk for nephrogenic systemic fibrosis (NSF)? In some cases, the answer is yes, according to a meta-analysis published December 9 in JAMA: Internal Medicine.  Discuss
Zr-89 immuno-PET could help predict cancer therapy outcomes
December 18, 2019 -- Researchers are one step closer to proving the worth of zirconium-89 (Zr-89) immuno-PET as a noninvasive approach to predict the effectiveness of therapy for cancerous tumors, according to a study published in the December issue of the Journal of Nuclear Medicine.  Discuss
PET/MRI tops MRI in breast lesion comparisons
December 13, 2019 -- PET/MRI is better than MRI alone for the detection and staging of nodes and distant metastases in women with breast cancer, according to a study presented by German researchers at the recent RSNA 2019 meeting.  Discuss
AI-based model aids fMRI in ADHD detection
December 11, 2019 -- A newly developed deep-learning artificial intelligence (AI) model is lending a helping hand to radiologists reading functional MRI (fMRI) scans, helping them better predict attention deficit hyperactivity disorder (ADHD), according to a study published online December 11 in Radiology: Artificial Intelligence.  Discuss
Can FDG-PET/MRI replace biopsy in breast cancer cases?
December 11, 2019 -- Although FDG-PET/MRI shows promise for accurate staging of breast cancer, the modality still isn't as accurate as sentinel lymph node biopsy, according to a study presented last week at RSNA 2019 in Chicago.  Discuss
PET and prejudice: Insurance firms' misconceptions
December 10, 2019 -- Healthcare insurance companies should value PET imaging and its cost-effective contributions to patient outcomes rather than view the modality as too expensive and unworthy of reimbursement, according to an editorial in the December issue of the Journal of Nuclear Medicine.  Discuss
ABUS delivers better diagnostic performance
December 9, 2019 -- Both automated breast ultrasound (ABUS) and traditional handheld ultrasound can significantly improve breast cancer detection when used as an adjunct to mammography in women with dense breasts. But ABUS yields better diagnostic performance, according to research presented at RSNA 2019 in Chicago.  Discuss
FDG-PET/CT within a year of heart valve surgery looks safe
December 4, 2019 -- CHICAGO - How soon after aortic prosthetic heart valve implantation can patients safely undergo FDG-PET/CT? A study presented Tuesday at the RSNA annual meeting found that such a scan within the first 12 months is quite feasible.  Discuss
