1. In this study of patients undergoing PET myocardial perfusion imaging, those with greater measured ischemia had improved overall and cardiac survival with early revascularization compared to medical therapy alone. 2. An ischemia threshold of 5% was determined, above which patients were observed to have greater benefit with early coronary...

1. In a retrospective cohort study of 12 patients with psoriasis, 8F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) demonstrated significantly increased arterial inflammation and subcutaneous adipose tissue inflammation compared to healthy controls. Evidence Rating Level: 3 (Average) Study Rundown: Psoriasis is a chronic, inflammatory skin disorder associated with an increased...
1. Positron emission tomography and magnetic resonance imaging (PET/MRI) was not as sensitive as PET and computed tomography (PET/CT) for the detection of small pulmonary nodules. 2. The majority of nodules that were missed when using PET/MRI either resolved or remained stable over time, suggestive of benignity, and did not...
1. A meta-analysis of amyloid-b-specific positron emission tomography studies in patients with dementia suggests that amyloid positivity decreases with age in patients with Alzheimer type dementia, while it increases in most non-Alzheimer type dementias. 2. Carriers of apolipoprotein E ε4 had higher mean prevalence of amyloid positivity than noncarriers making...
1. In a prospective cohort study of 25 patients with prosthetic vascular graft infections treated with systemic antibiotics, the use of FDG-PET/CT for monitoring of metabolic activity within the graft was effective at determining infection status and was used to alter the course of antibiotic therapy in all patients. Evidence...
Originally published by Harvard Health. What Is It? A positron emission tomography, or PET, scan is an imaging technique that uses positively charged particles (radioactive positrons) to detect subtle changes in the body's metabolism and chemical activities. A PET scan provides a color-coded image of the body's function, rather than its structure. During...
