Quiet T1-weighted imaging using PETRA: initial clinical evaluation in intracranial tumor patients

Autor: Masahiro, Ida, Toshiki, Wakayama, Matthew L, Nielsen, Takayuki, Abe, David M, Grodzki

Publikováno v: Journal of magnetic resonance imaging : JMRI. 41(2)

To compare the lesion contrast and signal to noise ratio (SNR) obtained with T1-weighted pointwise encoding time reduction with radial acquisition (PETRA) to those of Magnetization-Prepared RApid Gradient-Echo (MPRAGE) for contrast-enhanced imaging o

Publikováno v: Neurologia medico-chirurgica. 53(7)

The usefulness of 1.5-T high-field intraoperative magnetic resonance (iMR) imaging during transsphenoidal surgery for functioning pituitary adenomas was retrospectively evaluated based on long-term endocrine remission from the records of 14 patients

Evaluation of exercised or cooled skeletal muscle on the basis of diffusion-weighted magnetic resonance imaging

Autor: Osamu Yanagisawa, Matthew L. Nielsen, Daisuke Shimao, Katsuya Maruyama

Publikováno v: European journal of applied physiology. 105(5)

In this study, we assessed the physiological changes after exercising or cooling skeletal muscles on the basis of the apparent diffusion coefficient (ADC) values in magnetic resonance (MR) diffusion-weighted images (DWIs). DWIs of the ankle dorsiflex

Diffusion-weighted magnetic resonance imaging of human skeletal muscles: gender-, age- and muscle-related differences in apparent diffusion coefficient

Autor: Matthew L. Nielsen, Daisuke Shimao, Osamu Yanagisawa, Katsuya Maruyama, Mamoru Niitsu, Takeo Irie

Publikováno v: Magnetic resonance imaging. 27(1)

To evaluate the apparent diffusion coefficient (ADC) of skeletal muscle based on signal intensity (SI) attenuation vs. increasing b values and to determine ADC differences in skeletal muscles between genders, age groups and muscles.Diffusion-weighted
