Journal ArticleDOI
Breast lesions: correlation of contrast medium enhancement patterns on MR images with histopathologic findings and tumor angiogenesis.
L D Buadu,J Murakami,Sadayuki Murayama,Norihisa Hashiguchi,Shuji Sakai,Kouji Masuda,S. Toyoshima,Syoji Kuroki,Shinji Ohno +8 more
TL;DR: The density and distribution of microvessels may play major roles in the determination of the initial rate of contrast medium uptake and the heterogeneity of tumor enhancement.
Journal ArticleDOI
Parotid Gland Tumors: Can Addition of Diffusion-weighted MR Imaging to Dynamic Contrast-enhanced MR Imaging Improve Diagnostic Accuracy in Characterization?
Hidetake Yabuuchi,Yoshio Matsuo,Takeshi Kamitani,Taro Setoguchi,Takashi Okafuji,Hiroyasu Soeda,Shuji Sakai,Masamitsu Hatakenaka,Torahiko Nakashima,Yoshinao Oda,Hiroshi Honda +10 more
TL;DR: A persistent or flat Tic pattern on dynamic contrast-enhanced MR images indicates benign disease, but there is added value from including the ADC value in the evaluation of tumors that show a plateau or washout TIC pattern.
Journal ArticleDOI
Enhanced mass on contrast-enhanced breast MR imaging: Lesion characterization using combination of dynamic contrast-enhanced and diffusion-weighted MR images
Hidetake Yabuuchi,Yoshio Matsuo,Takashi Okafuji,Takeshi Kamitani,Hiroyasu Soeda,Taro Setoguchi,Shuji Sakai,Masamitsu Hatakenaka,Makoto Kubo,Noriaki Sadanaga,Hidetaka Yamamoto,Hiroshi Honda +11 more
TL;DR: To evaluate the diagnostic accuracy of a combination of dynamic contrast‐enhanced MR imaging (DCE‐MRI) and diffusion‐weighted MR Imaging (DWI) in characterization of enhanced mass on breast MR imaging and to find the strongest discriminators between carcinoma and benignancy.
Journal ArticleDOI
Non-mass-like enhancement on contrast-enhanced breast MR imaging: Lesion characterization using combination of dynamic contrast-enhanced and diffusion-weighted MR images
Hidetake Yabuuchi,Yoshio Matsuo,Takeshi Kamitani,Taro Setoguchi,Takashi Okafuji,Hiroyasu Soeda,Shuji Sakai,Masamitsu Hatakenaka,Makoto Kubo,Eriko Tokunaga,Hidetaka Yamamoto,Hiroshi Honda +11 more
TL;DR: The combination of DCE-MRI and DWI showed high diagnostic accuracy in characterization of non-mass-like enhancement lesions on breast MR images and found the strongest MR indicators of malignancy.
Journal ArticleDOI
Phyllodes Tumor of the Breast: Correlation between MR Findings and Histologic Grade
Hidetake Yabuuchi,Hiroyasu Soeda,Yoshio Matsuo,Takashi Okafuji,Takashi Eguchi,Shuji Sakai,Syoji Kuroki,Eriko Tokunaga,Shinji Ohno,Kenichi Nishiyama,Masamitsu Hatakenaka,Hiroshi Honda +11 more
TL;DR: Several MR findings can be used to help determine the histologic grade of phyllodes breast tumors, and irregular cyst wall corresponded histopathologically to hemorrhagic infarction and necrosis, respectively.
