Interrater reliability of a modified Ashworth scale of muscle spasticity.

Richard W. Bohannon, M Brewster Smith
Physical therapy
1987

We undertook this investigation to determine the interrater reliability of manual tests of elbow flexor muscle spasticity graded on a modified Ashworth scale. We each independently graded the elbow… (More)

7T vs. 4T: RF power, homogeneity, and signal-to-noise comparison in head images.

J. Thomas Vaughan, M. Garwood, +8 authors Kamil Ugurbil
Magnetic resonance in medicine
2001

Signal-to-noise ratio (SNR), RF field (B(1)), and RF power requirement for human head imaging were examined at 7T and 4T magnetic field strengths. The variation in B(1) magnitude was nearly twofold… (More)

The distributed model intercomparison project ( DMIP ) : motivation and experiment design

Steven G Reed, DongBack Seo, +5 authors S. Cong

SAR and B1 field distributions in a heterogeneous human head model within a birdcage coil. Specific energy absorption rate.

C. M. Collins, S. Li, M Brewster Smith
Magnetic resonance in medicine
1998

Calculations of radiofrequency magnetic (B1) field and specific energy absorption rate (SAR) distributions in a sphere of tissue and a multi-tissue human head model in a 12-element birdcage coil are… (More)

A telecommunications system for monitoring and counseling patients with hypertension. Impact on medication adherence and blood pressure control.

R. H. Friedman, Lewis E. Kazis, +4 authors Kate B Carey
American journal of hypertension
1996

This study was conducted to evaluate the effect of automated telephone patient monitoring and counseling on patient adherence to antihypertensive medications and on blood pressure control. A… (More)

Increased thermal stability of proteins in the presence of sugars and polyols.

Juhoon Back, D G Oakenfull, M Brewster Smith
Biochemistry
1979

Sugars and polyols stablize proteins against heat denaturation. Scanning calorimetry was used to obtain a quantitative estimate of the degree of stabilization. Solutions of ovalbumin, lysozyme,… (More)

Rat model of perinatal hypoxic-ischemic brain damage.

Riccardo Vannucci, J. R. Connor, +4 authors Susan J. Vannucci
Journal of neuroscience research
1999

To gain insights into the pathogenesis and management of perinatal hypoxic-ischemic brain damage, the authors have used an immature rat model which they developed many years ago. The model entails… (More)

Signal-to-noise ratio and absorbed power as functions of main magnetic field strength, and definition of "90 degrees " RF pulse for the head in the birdcage coil.

C. M. Collins, M Brewster Smith
Magnetic resonance in medicine
2001

Calculations of the RF magnetic (B(1)) field as a function of frequency between 64 and 345 MHz were performed for a head model in an idealized birdcage coil. Absorbed power (P(abs)) and SNR were… (More)

Removal of local field gradient artifacts in T2*-weighted images at high fields by gradient-echo slice excitation profile imaging.

Q. X. Yang, Gregory Williams, Roger Demeure, T. J. Mosher, M Brewster Smith
Magnetic resonance in medicine
1998

Development of high magnetic field MRI techniques is hampered by the significant artifacts produced by B0 field inhomogeneities in the excited slices. A technique, gradient-echo slice excitation… (More)

Spatial variation of T2 in human articular cartilage.

Bernard J. Dardzinski, T. J. Mosher, S. Li, M A Van Slyke, M Brewster Smith
Radiology
1997

PURPOSE To determine the spatial variation of in vivo cartilage T2 in young asymptomatic adults. MATERIALS AND METHODS Quantitative T2 maps of seven asymptomatic young male adults and one male… (More)
