Journal ArticleDOI
Multicenter cross-calibration of I-123 metaiodobenzylguanidine heart-to-mediastinum ratios to overcome camera-collimator variations
Kenichi Nakajima,Koichi Okuda,Mana Yoshimura,Shinro Matsuo,Hiroshi Wakabayashi,Yasuhiro Imanishi,Seigo Kinuya +6 more
TL;DR: By using the reference HMR and conversion coefficients for the system, HMRs with various conditions can be converted to the standard H MRs in a range of normal to low HMRS.
Journal ArticleDOI
Enhanced diagnostic accuracy for quantitative bone scan using an artificial neural network system: a Japanese multi-center database project
Kenichi Nakajima,Yasuo Nakajima,Hiroyuki Horikoshi,Munehisa Ueno,Hiroshi Wakabayashi,Tohru Shiga,Mana Yoshimura,Eiji Ohtake,Yoshifumi Sugawara,Hideyasu Matsuyama,Lars Edenbrandt +10 more
TL;DR: In the software for calculating BSI, the multi-institutional database significantly improved identification of bone metastasis compared with the original database, indicating the importance of a sufficient number of training databases including various types of cancers.
Journal ArticleDOI
Improved quantification of small hearts for gated myocardial perfusion imaging
Kenichi Nakajima,Koichi Okuda,Karin Nyström,Jens Richter,David Minarik,Hiroshi Wakabayashi,Shinro Matsuo,Seigo Kinuya,Lars Edenbrandt,Lars Edenbrandt +9 more
TL;DR: The volume-dependent edge correction algorithm was able to effectively reduce the effects on ESV and EF of a small heart and might be applicable to both men and women and to both small and normal-sized hearts.
Journal ArticleDOI
Bone scintigraphy as a new imaging biomarker: the relationship between bone scan index and bone metabolic markers in prostate cancer patients with bone metastases
Hiroshi Wakabayashi,Kenichi Nakajima,Atsushi Mizokami,Mikio Namiki,Anri Inaki,Junichi Taki,Seigo Kinuya +6 more
TL;DR: The changes in BSI showed a close relationship with all bone metabolic markers but not with the serum PSA, and is confirmed to reflect the activity and extent of bone metastases and can be used as an imaging biomarker.
Journal ArticleDOI
Effects and safety of ¹³¹I-metaiodobenzylguanidine (MIBG) radiotherapy in malignant neuroendocrine tumors: results from a multicenter observational registry.
Keiichiro Yoshinaga,Noboru Oriuchi,Hiroshi Wakabayashi,Yuuki Tomiyama,Megumi Jinguji,Tetsuya Higuchi,Daiki Kayano,Makoto Fukuoka,Anri Inaki,Ayane Toratani,Shozo Okamoto,Tohru Shiga,Yoichi M. Ito,Masatoyo Nakajo,Masayuki Nakajo,Seigo Kinuya +15 more
TL;DR: Evaluating the effects and safety of iodine-131 metaiodobenzylguanidine radiotherapy for conditions including malignant pheochromocytoma and paraganglioma within a multicenter cohort indicated that most of the ¹³¹I-MIBG radiotherapy was performed safely without significant side effects.
