Autor: Daisuke Utsunomiya, Seitaro Oda, Shuichiro Okumura, Hiroki Arimura, Eri Hayashida, Satomi Tajiri, Akira Sasao, Takashi Okigawa, Joji Urata, Hirohumi Wada, Yasuyuki Yamashita

Publikováno v: Magnetic Resonance in Medical Sciences. 13:1-6

Purpose Differences in acute adverse reactions to different gadolinium (Gd)-based contrast agents have not been thoroughly evaluated. We investigated the relationships among the incidence and severity of acute adverse reactions, backgrounds of patien

Secondary Signal Change and an Apparent Diffusion Coefficient Decrease of the Substantia Nigra After Striatal Infarction

Autor: Toshiro Yonehara, Makoto Nakajima, Takashi Okigawa, Yuichiro Inatomi, Teruyuki Hirano

Publikováno v: Stroke. 44:213-216

Background and Purpose— Diffusion-weighted imaging can depict secondary signal change of the substantia nigra of patients with ipsilateral striatal infarction via a decrease in the apparent diffusion coefficient (ADC). Clinical predictors of this p

Publikováno v: Japanese Journal of Radiological Technology. 68:817-824

Various three-dimensional fast spin echo (3D-FSE) sequences are used for non-contrast magnetic resonance angiography (MRA). Differences in the ability to detect vascular stenosis using these sequences, however, have not yet been evaluated. The purpos

Autor: Yosuke Komeda, Joji Urata, Daisuke Utsunomiya, Yohei Nomitsu, Takashi Okigawa, Yasuyuki Yamashita, Mitsue Miyazaki

Publikováno v: Circulation Journal. 72:1627-1630

Background The association between a gadolinium-based contrast material and nephrogenic systemic fibrosis has been discussed. The purpose of our study was to evaluate whether non-contrast enhanced magnetic resonance angiography (MRA) might provide su
