Hirokazu Watanabe,Morihito Okada,Yasushi Kaji,Miyako Satouchi,Yozo Sato,Yuichiro Yamabe,Hiroaki Onaya,Masahiro Endo,Miyuki Sone,Yasuaki Arai +9 more
TL;DR: This paper is an overview of the new response evaluation criteria in solid tumours: revised RECIST guideline (version 1. 1), with a focus on updated contents.
Journal ArticleDOI
Evaluation of Cartilage Invasion by Laryngeal and Hypopharyngeal Squamous Cell Carcinoma with Dual-Energy CT
Hirofumi Kuno,Hiroaki Onaya,Ryoko Iwata,Tatsushi Kobayashi,Satoshi Fujii,Ryuichi Hayashi,Katharina Otani,Hiroya Ojiri,Takeharu Yamanaka,Mitsuo Satake +9 more
TL;DR: Combined analysis of WA and IO images obtained with dual-energy CT improves the diagnostic performance and interobserver reproducibility of evaluations of laryngeal cartilage invasion by SCC.
Journal ArticleDOI
Preoperative evaluation of invasive and noninvasive intraductal papillary-mucinous neoplasms of the pancreas: clinical, radiological, and pathological analysis of 123 cases.
Satoshi Nara,Hiroaki Onaya,Nobuyoshi Hiraoka,Kazuaki Shimada,Tsuyoshi Sano,Yoshihiro Sakamoto,Minoru Esaki,Tomoo Kosuge +7 more
TL;DR: Investigation of preoperative findings that are useful to distinguish intraductal papillary-mucinous neoplasm (IPMN) subtypes found a strong correlation with the presence of malignancy in patients with IPMN, and it is recommended to rule out IC-IPMC using multidetector-row computed tomography and categorize IPMN other than IC- IPMC according to malignant potential based on the diagnostic score.
Journal ArticleDOI
Tumor response evaluation criteria for HCC (hepatocellular carcinoma) treated using TACE (transcatheter arterial chemoembolization): RECIST (response evaluation criteria in solid tumors) version 1.1 and mRECIST (modified RECIST): JIVROSG-0602
Yozo Sato,Hirokazu Watanabe,Miyuki Sone,Hiroaki Onaya,Noriaki Sakamoto,Keigo Osuga,Masahide Takahashi,Yasuaki Arai +7 more
TL;DR: From the viewpoint of the high inter- and intra-observer reproducibility, mRECIST may be more suitable for tumor response criteria in clinical trials of TACE for HCC.
Journal ArticleDOI
Primary staging of laryngeal and hypopharyngeal cancer: CT, MR imaging and dual-energy CT.
TL;DR: Radiologists need to understand the advantages and limitations of each imaging modality for staging of laryngeal and hypopharyngeAL cancer.
