Magnetic resonance imaging using laser-polarized 129Xe is a new technique first demonstrated by Albert et. al. (Nature 370, 1994) who obtained a 129Xe image of an excised mouse lung. This paper describes the factors influencing the accumulation of inhaled, polarized 129Xe in human tissue. The resulting model predicts the 129Xe magnetization in different(More)
The intrinsic phosphocreatine (PCr) T1 values measured by time-dependent magnetization transfer in isolated perfused rat, hamster, and turkey hearts were indistinguishable. The value of 3.5 +/- 0.3 s for the rat heart is similar to values measured by other magnetization transfer methods. Irreversibly inhibiting the phosphoryl exchange between PCr and ATP in(More)
BACKGROUND The Surgical Care Improvement Project (SCIP) was launched in 2005. The core prophylactic perioperative antibiotic guidelines were created due to recognition of the impact of proper perioperative prophylaxis on an estimated annual one million inpatient days and $1.6 billion in excess health care costs secondary to preventable surgical site(More)
