Autor: Masaki Niiro, Wataru Hirakawa, Akihiro Haruzono, Toshiro Fujimoto, Masahiro Sasahira, Tetsuhiko Asakura, Tetsuro Matsumoto
Publikováno v: Neurologia medico-chirurgica. 35:277-284
Functional magnetic resonance (MR) imaging of the brain was performed during motor task activation in five normal subjects and a patient with meningioma using conventional fast low-angle shot sequences and a 2.0 T system. A high intensity area in the

Publikováno v: Endocrine pathology. 9(1)
Histologically, cholesterol clefts are often observed in craniopharyngioma, Rathke's cleft cyst, and various granulomas. However, pituitary adenomas with cholesterol clefts are rare. A 46-year-old woman developed visual field disturbance. She had no

31P chemical shift imaging of intracranial tumours
Autor: Masaki Niiro, K. Uchimura, Wataru Hirakawa, A. Haruzono, M. Sasahira, T. Fujimoto, Tetsuhiko Asakura, N. Moriya, K. Terada
Publikováno v: Proceedings of the XV Symposium Neuroradiologicum ISBN: 9783642794360
Chemical shift imaging is useful to obtain spectra of multiple contiguous voxels simultaneously and to demonstrate detailed mapping of metabolites. 31P magnetic resonance (MR) spectra of intracranial tumours are different from those of normal brain t

A study of epileptogenic foci with 31P-chemical shift imaging
Autor: M. Sasahira, A. Haruzono, Wataru Hirakawa, T. Asakura, T. Fujimoto, K. Nakamura
Publikováno v: Proceedings of the XV Symposium Neuroradiologicum ISBN: 9783642794360
The subjects of this study were 36 epilepsy patients aged 8–62 years, who were examined 45 times; 25 had partial and 11, generalised seizures.31-chemical shift imaging (CSI) was acquired with three-dimensional Fourier transformation (3DFT) multivox

Functional MRI of human motor cortex using a conventional MRI system
Autor: A. Haruzono, Tetsuhiko Asakura, M. Niiro, M. Sasahira, Wataru Hirakawa, T. Fujimoto
Publikováno v: Proceedings of the XV Symposium Neuroradiologicum ISBN: 9783642794360
Functional MRI of the brain was performed with motor task activation in normal volunteers and a patient with a meningioma using conventional FLASH sequences and a 2.0 T MRI system. A bright signal intensity in the motor cortex was observed in all cas
