Analysis finds variance in uptake of amyloid PET tracers
May 19, 2015 -- PET scans can detect varying levels of amyloid in the brain that change with age and the presence of a genotype linked to Alzheimer's disease, according to a meta-analysis in the May Journal of the American Medical Association. The findings may enable clinicians to better tailor which patients receive the scans.
New PET tracer homes in on metastatic prostate cancer
May 15, 2015 -- Researchers from Johns Hopkins University have developed a PET radiopharmaceutical for imaging metastatic prostate cancer that so far has shown superior image quality with less radiation exposure in most radiosensitive organs than its predecessor.
Prescan review slashes inpatient use of PET/CT
May 12, 2015 -- A New Jersey hospital was able to slash by more than half the number of inpatient pulmonary PET/CT scans being performed by having its nuclear medicine department act as a gatekeeper for exam orders, according to a study presented at the recent American Roentgen Ray Society annual meeting.
SPECT differentiates PTSD from TBI in military veterans
May 11, 2015 -- Add SPECT to the list of imaging modalities that can help physicians distinguish between post-traumatic stress disorder (PTSD) and traumatic brain injury (TBI), potentially leading to more appropriate treatment for military veterans.
NEJM: PET for Hodgkin's lymphoma prevents unnecessary radiotherapy
April 23, 2015 -- A negative PET scan immediately after three cycles of chemotherapy for early-stage Hodgkin's lymphoma can identify patients with an excellent prognosis and avoid unnecessary additional radiation therapy, according to a U.K. study published on 23 April in the New England Journal of Medicine.
Chest pain patients do well after ultralow-dose SPECT
April 10, 2015 -- Patients with chest pain who underwent SPECT myocardial perfusion imaging with an ultralow-radiation-dose gamma camera had no major cardiac events a year later. The research, published in the April issue of the Journal of Nuclear Medicine, indicates that MPI radiation dose can be slashed without adverse clinical impact.
FDDNP-PET gives insight into brain trauma of NFL players
April 7, 2015 -- Brain scans with the PET radiopharmaceutical FDDNP of former National Football League (NFL) players who experienced multiple concussions show patterns that are similar to patients who experienced chronic traumatic encephalopathy, according to an April 6 study in the Proceedings of the National Academy of Sciences.
ACR, SNMMI set standards for reading PET/MRI brain scans
March 19, 2015 -- The American College of Radiology (ACR) and the Society of Nuclear Medicine and Molecular Imaging (SNMMI) have released the first in a series of requirements for physicians and clinicians interested in gaining proficiency in reading PET/MRI scans.
ACC: PET/CT trumps SPECT for cardiac studies
March 17, 2015 -- Researchers from Utah found that PET/CT is far superior to SPECT for diagnosing myocardial ischemia, with higher sensitivity at a lower radiation dose, according to a paper presented on Sunday at the American College of Cardiology (ACC) meeting in San Diego. PET/CT in particular far outstripped SPECT in determining that patients were free of cardiac disease.
Adults at low risk of heart disease shouldn't get screening
March 16, 2015 -- Cardiac screening shouldn't be performed on patients at low risk for coronary heart disease, as it doesn't improve patient outcomes and comes with potential harms due to false-positive results, according to a paper published on Monday in the Annals of Internal Medicine by the American College of Physicians.
