Simulations of the effect of diffusion on asymmetric spin echo based quantitative BOLD: An investigation of the origin of deoxygenated blood volume overestimation
Autor: Alan J, Stone, Naomi C, Holland, Avery J L, Berman, Nicholas P, Blockley
Publikováno v: Neuroimage
Quantitative BOLD (qBOLD) is a technique for mapping oxygen extraction fraction (OEF) and deoxygenated blood volume (DBV) in the human brain. Recent measurements using an asymmetric spin echo (ASE) based qBOLD approach produced estimates of DBV which

Transverse signal decay under the weak field approximation: Theory and validation
Autor: Avery J L, Berman, G Bruce, Pike
Publikováno v: Magnetic resonance in medicine. 80(1)
To derive an expression for the transverse signal time course from systems in the motional narrowing regime, such as water diffusing in blood. This was validated in silico and experimentally with ex vivo blood samples.A closed-form solution (CFS) for

The effect of dissolved oxygen on the relaxation rates of blood plasma: Implications for hyperoxia calibrated BOLD
Autor: Yuhan, Ma, Avery J L, Berman, G Bruce, Pike
Publikováno v: Magnetic resonance in medicine. 76(6)
To determine the contribution of paramagnetic dissolved oxygen in blood plasma to blood-oxygenation-level-dependent (BOLD) signal changes in hyperoxic calibrated BOLD studies.Bovine blood plasma samples were prepared with partial pressures of oxygen

The effect of dissolved oxygen on the susceptibility of blood
Autor: Avery J L, Berman, Yuhan, Ma, Richard D, Hoge, G Bruce, Pike
Publikováno v: Magnetic resonance in medicine. 75(1)
It has been predicted that, during hyperoxia, excess O2 dissolved in arterial blood will significantly alter the blood's magnetic susceptibility. This would confound the interpretation of the hyperoxia-induced blood oxygenation level-dependent signal

One state's response to the malpractice insurance crisis: North Carolina's Rural Obstetrical Care Incentive Program
Autor: D H, Taylor, T C, Ricketts, J L, Berman, J T, Kolimaga
Publikováno v: Public health reports (Washington, D.C. : 1974). 107(5)
In the period 1985-89, there was a severe drop in obstetrical services in rural areas of North Carolina, partly because of rising malpractice insurance rates. The State government responded with the Rural Obstetrical Care Incentive (ROCI) Program tha

Multiple-lead QRS changes with exercise testing. Diagnostic value and hemodynamic implications
Autor: Peter F. Cohn, J L Berman, Joshua Wynne
Publikováno v: Circulation. 61:53-61
To evaluate the diagnostic potential and hemodynamic significance of exercise-induced multiple-lead QRS changes, we studied exercise test responses in 230 patients with chest pain syndromes undergoing Bruce protocol exercise tests. When increases in

Computed and conventional arthrotomography of the glenohumeral joint: normal anatomy and clinical experience
Autor: D Resnick, Jose Guerra, rd R O Cone, J L Berman, Andrew L. Deutsch, Jerrold H. Mink, Larry A. Danzig, C S Resnik
Publikováno v: Radiology. 153:603-609
The glenohumeral joint was studied in 25 cadavers and 136 patients using computed arthrotomography (CAT) and conventional arthrotomography (AT) to assess shoulder instability. Cadaver shoulders were injected with air or latex, sectioned with a band s

A multivariate approach for interpreting treadmill exercise tests in coronary artery disease
Autor: Peter F. Cohn, Joshua Wynne, J L Berman
Publikováno v: Circulation. 58:505-512
To determine the value of a multivariate approach for the analysis of the treadmill exercise tolerance test (ETT), 237 patients referred for evaluation of chest pain who underwent a standard Bruce protocol ETT and coronary arteriography were studied.
