PET-CT Helps Diagnose Cardiac Sarcoidosis
Combined FDG PET-CT can help uncover secondary sites of cardiac sarcoidosis (CS), according to a study published in the Journal of Nuclear Cardiology.
Researchers from the University of Illinois in Chicago and the University of Texas MD Anderson Cancer Center in Houston performed a retrospective study to investigate the relationship between cardiac and extra-thoracic sarcoid findings on FDG PET-CT using a 72-hour pretest high-fat, high-protein, and very low-carbohydrate (HFHPVLC) diet.

Role of PET/CT in Management of Early Lung Adenocarcinoma
The purpose of this study was to explore the value of FDG PET combined with high-resolution CT (HRCT) in predicting the pathologic subtypes and growth patterns of early lung adenocarcinoma. Read more.
How does Oxygen-15 positron emission tomography characterization of cerebral physiology after traumatic brain injury inform clinical practice?
In this single-center observational cohort study of 68 patients and 27 control participants, early ischemia was common in patients, but hyperemia coexisted in different brain regions. Cerebral blood volume was consistently increased, despite low cerebral blood flow. Read more.
A neurobiological mechanism linking transportation noise to cardiovascular disease in humans
Chronic noise exposure associates with increased cardiovascular disease (CVD) risk; however, the role of confounders and the underlying mechanism remain incompletely defined. The amygdala, a limbic centre involved in stress perception, participates in the response to noise. Higher amygdalar metabolic activity (AmygA) associates with increased CVD risk through a mechanism involving heightened arterial inflammation (ArtI). Accordingly, in this retrospective study, we tested whether greater noise exposure associates with higher: (i) AmygA, (ii) ArtI, and (iii) risk for major adverse cardiovascular disease events (MACE).

Radioisotope couple for tumor diagnosis and therapy
Researchers at Kanazawa University report a promising combination of radioisotope-carrying molecules for use in radiotheranostics—a diagnosis and treatment approach based on the combination of medical imaging and internal radiation therapy with radioactive elements. Read more.
