Quantitative measurement of portal blood flow by magnetic resonance phase contrast: comparative study of flow phantom and Doppler ultrasound in vivo. (2007)

Tsunoda, Masatoshi, Kimoto, Shin, Hamazaki, Keisuke, Takeda, Yoshihiro, Hiraki, Yoshio

A non-invasive method for measuring portal blood flow by magnetic resonance (MR) phase contrast was evaluated in a flow phantom and 20 healthy volunteers. In a flow phantom study, the flow volumes...

Differential diagnosis of adrenal masses by chemical shift and dynamic gadolinium enhanced MR imaging. (2006)

Sasai, Nobuya, Togami, Izumi, Tsunoda, Masatoshi, Sei, Tetsuro, Akaki, Shiro, Hiraki, Yoshio

Chemical shift MRI is widely used for identifying adenomas, but it is not a perfect method. We determined whether combined dynamic MRI methods can lead to improved diagnostic accuracy. Fifty-seven...

Kinematic magnetic resonance imaging (MRI) of the normal shoulder: assessment of the shapes and signals of the superior and inferior labra with abductive movement using an open-type imager. (2006)

Togami, Izumi, Sasai, Nobuya, Tsunoda, Masatoshi, Sei, Tetsuro, Yabuki, Takayuki, Kitagawa, Takahiro, ...

A preliminary study was conducted to evaluate the superior and inferior glenoid labra with abductive movement using an open-type MR unit in asymptomatic healthy volunteers. Both fast low angle shot...

Experimental study of fast and ultrafast T2-weighted imaging sequences using AMI-25 superparamagnetic iron oxide (SPIO). (2006)

Kurokawa, Hironori, Togami, Izumi, Tsunoda, Masatoshi, Hikari, Yoshio

The objective of this study was to evaluate fast and ultrafast T2-weighted images (T2WI), including echo planar imaging (EPI), using an AMI-25 agar phantom. Image quality for conventional spin echo...

Cerebral perfusion MR imaging using FAIR-HASTE in chronic carotid occlusive disease: comparison with dynamic susceptibility contrast-perfusion MR imaging. (2006)

Ida, Kentaro, Akaki, Shiro, Sei, Tetsuro, Tsunoda, Masatoshi, Kanazawa, Susumu

To determine the efficacy of flow-sensitive alternating inversion recovery using half-Fourier single-shot turbo spin-echo (FAIR-HASTE) in detecting cerebral hypoperfusion in chronic carotid occlusive...
