Magnetic resonance imaging of peripheral venous distension with cyclooxygenase inhibition in healthy humans

Autor: J. Carter Luck, Takuto Hamaoka, Christopher Sica, Jeffrey Vesek, Cheryl Blaha, Jon Stavres, Urs Leuenberger, Lawrence Sinoway, Jian Cui

Publikováno v: Physiology. 38

Background: Peripheral venous distension, induced by a volume infusion into the veins in an occluded limb, evokes a reflex pressor and sympathoexcitatory response in humans (venous distension reflex, VDR). However, to what extent the procedure alters

Magnetic resonance T1w/T2w ratio: A parsimonious marker for Parkinson disease

Autor: Guangwei, Du, Mechelle M, Lewis, Christopher, Sica, Lan, Kong, Xuemei, Huang

Publikováno v: Annals of neurology. 85(1)

Newer magnetic resonance imaging (MRI) techniques have shown promise in capturing early Parkinson disease (PD)-related changes in the substantia nigra pars compacta (SNc), the key pathological loci. Their translational value, however, is hindered by

Improved first-pass spiral myocardial perfusion imaging with variable density trajectories

Autor: Michael, Salerno, Christopher, Sica, Christopher M, Kramer, Craig H, Meyer

Publikováno v: Magnetic resonance in medicine. 70(5)

To develop and evaluate variable-density spiral first-pass perfusion pulse sequences for improved efficiency and off-resonance performance and to demonstrate the utility of an apodizing density compensation function (DCF) to improve signal-to-noise r
