Journal ArticleDOI
Evaluation of quality of life and psychological response in cancer patients treated with radiotherapy.
Takeo Takahashi,Mikito Hondo,Keiichiro Nishimura,Akira Kitani,Takafumi Yamano,Hisami Yanagita,Hisato Osada,Munefumi Shinbo,Norinari Honda +8 more
TL;DR: The authors could treat cancer patients by radiotherapy without reducing their QOL, and improvement in QOL was significant in the palliative radiotherapy group, and mental condition was also improved after radiotherapy.
Journal ArticleDOI
Imaging of ventilation with dual-energy CT during breath hold after single vital-capacity inspiration of stable xenon
Norinari Honda,Hisato Osada,Wataru Watanabe,Mitsuo Nakayama,Keiichiro Nishimura,Bernhard Krauss,Katharina Otani +6 more
TL;DR: Xenon-enhanced dual-energy CT with the single-breath-hold technique could depict ventilation in phantoms and in four volunteers, and had better image quality on visual comparison than those calculated by using subtraction.
Journal ArticleDOI
Usefulness of double dose contrast-enhanced magnetic resonance imaging for clear delineation of gross tumor volume in stereotactic radiotherapy treatment planning of metastatic brain tumors: a dose comparison study
Kalloo Sharma Subedi,Takeo Takahashi,Takafumi Yamano,Jun-ichi Saitoh,Keiichiro Nishimura,Yoshiyuki Suzuki,Tatsuya Ohno,Takashi Nakano +7 more
TL;DR: It is concluded that double dose contrast-enhanced thin-slice MRI is a more useful technique than single dose Contrast-enhancement for clear delineation of GTVs of small metastatic brain tumors in treatment planning of highly precise SRT.
Journal ArticleDOI
Measurement of repositioning accuracy during fractionated stereotactic radiotherapy for intracranial tumors using noninvasive fixation of BrainLAB radiotherapy equipment
TL;DR: The BrainLAB noninvasive SRT fixation device was considered useful for routine treatment with high accuracy for repositioning times determined by comparing the relative coordinates.
Journal ArticleDOI
Quantitative lung perfusion scintigraphy and detection of intrapulmonary shunt in liver cirrhosis.
Makoto Hosono,Kikuo Machida,Norinari Honda,Takeo Takahashi,Kashimada A,Hisato Osada,Osamu Murata,Nobuyuki Ohtawa,Keiichiro Nishimura +8 more
TL;DR: In the cirrhosis patients with hypoxemia, the presence of intrapulmonary shunt was confirmed on quantitative lung perfusion scan, and the timing, of measurements is essential in evaluating intrapu pulmonary shunt.
