Journal ArticleDOI
A rapid plethysmographic method for measuring thoracic gas volume: a comparison with a nitrogen washout method for measuring functional residual capacity in normal subjects
Journal ArticleDOI
Reversibility of Cardiac Wall-Motion Abnormalities Predicted by Positron Tomography
Jan H. Tillisch,Richard C. Brunken,Robert C. Marshall,Markus Schwaiger,M. Mandelkern,Michael E. Phelps,Heinrich R. Schelbert +6 more
TL;DR: PET imaging with 13NH3 to assess blood flow and 18FDG to assess the metabolic viability of the myocardium is an accurate method of predicting potential reversibility of wall-motion abnormalities after surgical revascularization.
Journal ArticleDOI
Identification and differentiation of resting myocardial ischemia and infarction in man with positron computed tomography, 18F-labeled fluorodeoxyglucose and N-13 ammonia.
Robert C. Marshall,Jan H. Tillisch,Michael E. Phelps,Sung-Cheng Huang,Richard E. Carson,Eberhard Henze,Heinrich R. Schelbert +6 more
TL;DR: The changes in regional FDG and N-13 ammonia concentrations detected with PCT in patients who had had a recent myocardial infarction are consistent with regional exogenous glucose utilization and perfusion in moderately ischemic and irreversibly infarcted myocardium.
Journal ArticleDOI
Regional perfusion, glucose metabolism, and wall motion in patients with chronic electrocardiographic Q wave infarctions: evidence for persistence of viable tissue in some infarct regions by positron emission tomography.
Richard C. Brunken,Jan H. Tillisch,Markus Schwaiger,John S. Child,Robert C. Marshall,M Mandelkern,M.E. Phelps,Heinrich R. Schelbert +7 more
TL;DR: Positron tomography reveals evidence of persistent tissue metabolism in a high proportion of chronic electrocardiographic Q wave regions, and commonly used clinical tests do not reliably distinguish hypoperfused but viable regions from tomographically defined regions of myocardial infarction.
Journal ArticleDOI
Current pharmacologic treatment of dementia: a clinical practice guideline from the American College of Physicians and the American Academy of Family Physicians

TL;DR: The target patient population is patients receiving a diagnosis of pulmonary embolism or lower-extremity deep venous thrombosis, and all clinicians caring for patients who have been given a diagnosis.
