Myocardial perfusion reserve compared with peripheral perfusion reserve: a [13N]ammonia PET study [PDF]

, 2011
13N]ammonia PET allows quantification of myocardial perfusion. The similarity between peripheral flow and myocardial perfusion is unclear. We compared perfusion flow in the myocardium with the upper limb during rest and adenosine stress [13N]ammonia PET ...

Large‐Vessel Vasculitis: Interobserver Agreement and Diagnostic Accuracy of 18F‐FDG‐PET/CT

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
Introduction. 18F‐FDG‐PET visualises inflammation. Both atherosclerosis and giant cell arteritis cause vascular inflammation, but distinguishing the two may be difficult. The goal of this study was to assess interobserver agreement and diagnostic accuracy of 18F‐FDG‐PET for the detection of large artery involvement in giant cell arteritis (GCA ...
