Journal ArticleDOI
Usefulness of diffusion-weighted MRI with echo-planar technique in the evaluation of cellularity in gliomas.
Takeshi Sugahara,Yukunori Korogi,Masato Kochi,Ichiro Ikushima,Yoshinori Shigematu,Toshinori Hirai,T. Okuda,Luxia Liang,Yulin Ge,Yasuyuki Komohara,Yukitaka Ushio,Mutsumasa Takahashi +11 more
TL;DR: Diffusion‐weighted MRI with EPI is a useful technique for assessing the tumor cellularity and grading of gliomas and is useful for the diagnosis and characterization ofgliomas.
Journal ArticleDOI
Correlation of MR imaging-determined cerebral blood volume maps with histologic and angiographic determination of vascularity of gliomas.
Takeshi Sugahara,Yukunori Korogi,Masato Kochi,Ichiro Ikushima,Toshinori Hirai,T. Okuda,Yoshinori Shigematsu,Luxia Liang,Yulin Ge,Yukitaka Ushio,Mutsumasa Takahashi +10 more
TL;DR: The results of perfusion-sensitive MR imaging with gradient-echo echoplanar technique correlated with both histologic and angiographic vascularities.
ORIGINAL RESEARCH Diffusion-weighted Imaging of Metastatic Brain Tumors: Comparison with Histologic Type and Tumor Cellularity
Y. Hayashida,Toshinori Hirai,S. Morishita,Mika Kitajima,R. Murakami,Y. Korogi,K. Makino,H. Nakamura,Ichiro Ikushima,Masayuki Yamura,Masato Kochi,Y. Yamashita +11 more
TL;DR: The SI on DWI may predict the histology of metastases; well differentiated adenocarcinomas tended to be hypointense, and small- and large-cell neuroendocrine carcinomas showed hyperintensity.
Journal Article
Diffusion-weighted imaging of metastatic brain tumors: comparison with histologic type and tumor cellularity
Yoshiko Hayashida,Toshinori Hirai,S. Morishita,M. Kitajima,R. Murakami,Yukunori Korogi,Keishi Makino,Hideo Nakamura,Ichiro Ikushima,Masayuki Yamura,Masato Kochi,Jun Ichi Kuratsu,Y. Yamashita +12 more
TL;DR: In this paper, Wang et al. measured the contrast-to-noise ratio (CNR) on T2-weighted images and normalized apparent diffusion coefficient (nADC) values, and compared them with tumor cellularity.
Journal Article
Diffusion-Weighted Imaging of Radiation-Induced Brain Injury for Differentiation from Tumor Recurrence
Chiaki Asao,Yukunori Korogi,Mika Kitajima,Toshinori Hirai,Yuji Baba,Keishi Makino,Masato Kochi,Shoji Morishita,Yasuyuki Yamashita +8 more
TL;DR: In this paper, the diffusion-weighted imaging (DWI) was used to distinguish between tumor recurrence and treatment-related brain injury with conventional MR images, and the results showed that DWI was useful in differentiating recurrent neoplasm from radiation necrosis.
