Altered muscle metabolism shown by magnetic resonance spectroscopy in sickle cell disease with leg ulcers

Autor: Michael R. Terk, Patrick M. Colletti, William D. Boswell, James M. Halls, L. Julian Haywood, Sharon L. Norris, Joel R. Gober

Publikováno v: Magnetic Resonance Imaging. 11:119-123

We performed 31P magnetic resonance spectroscopy of gastrocnemius muscle at rest in 7 normal volunteers and 12 patients with sickle cell disease (7 with leg ulcers and 5 without leg ulcers but with painful crises). We measured intracellular pH and ra

Changes in high-energy phosphate metabolism may be important in the regulation of myocardial contractile function during ischemia. This study sought to determine the dynamic relation between myocardial contractile function and high-energy phosphate m

Relationship between myocardial metabolites and contractile abnormalities during graded regional ischemia. Phosphorus-31 nuclear magnetic resonance studies of porcine myocardium in vivo

Publikováno v: Journal of Clinical Investigation. 85:706-713

The mechanisms responsible for changes in myocardial contractility during regional ischemia are unknown. Since changes in high-energy phosphates during ischemia are sensitive to reductions in myocardial blood flow, it was hypothesized that myocardial

Evaluation of suspected musculoskeletal neoplasms using 3D T2-weighted spectral presaturation with inversion recovery

Autor: Howard E. Simon, Hans J. de Verdier, Michael R. Terk, Joel R. Gober, Patrick M. Colletti

Publikováno v: Magnetic resonance imaging. 11(7)

This study evaluated the use of the Spectral presaturation with inversion recovery (SPIR) technique with T2-weighting in 43 pathologically proven cases of suspected musculoskeletal neoplasm. Both primary and secondary malignant neoplasms as well as b

SPIR MRI in spinal diseases

Autor: Joel R. Gober, Chi S. Zee, Patrick M. Colletti, Hervey D. Segall, Michael R. Terk, Sylvie Destian, Jamshid Ahmadi

Publikováno v: Journal of computer assisted tomography. 16(3)

We report on our experience with the fat suppression technique of spectral presaturation with inversion recovery MR in imaging certain spinal disorders. This technique may assist in demonstrating or excluding the presence of fat within a lesion (such

Metabolic and functional consequences of blunted myocardial reactive hyperemia

Autor: Joe G.N. Garcia, Saul Schaefer, Barry M. Massie, S. K. Steinman, Michael Weiner, Gregory G. Schwartz, S. D. Trocha, Joel R. Gober

Publikováno v: The American journal of physiology. 261(3 Pt 2)

This study determined whether the rapidity of myocardial metabolic and contractile recovery after brief coronary occlusion depends upon the intensity of reactive hyperemia. We also tested the hypothesis that coronary flow rate modulates contractility

Myocardial high-energy phosphates in reactive hyperemia

Autor: A. Smekal, Dieter J. Meyerhoff, Michael W. Weiner, Joel R. Gober, Barry M. Massie, Gregory G. Schwartz, Saul Schaefer

Publikováno v: The American journal of physiology. 259(4 Pt 2)

This study used 31P nuclear magnetic resonance (NMR) spectroscopy to determine whether the magnitude and duration of myocardial reactive hyperemia (RH) reflect a commensurate derangement of myocardial high-energy phosphate (HEP) metabolism, or if cor

Publikováno v: The American journal of cardiology. 65(16)

The goals of this study were to determine whether abnormalities in phosphorus metabolism could be noninvasively detected using phosphorus-31 nuclear magnetic resonance spectroscopy in patients with dilated cardiomyopathy and left ventricular hypertro
