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.
Journal Article
Posttherapeutic Intraaxial Brain Tumor: The Value of Perfusion-sensitive Contrast-enhanced MR Imaging for Differentiating Tumor Recurrence from Nonneoplastic Contrast-enhancing Tissue
Takeshi Sugahara,Yukunori Korogi,Seiji Tomiguchi,Yoshinori Shigematsu,Ichiro Ikushima,Tomohiro Kira,Luxia Liang,Yukitaka Ushio,Mutsumasa Takahashi +8 more
TL;DR: An enhancing lesion with a normalized rCBV ratio higher than 2.6 or lower than 0.6 may suggest tumor recurrence or nonneoplastic contrast-enhancing tissue, respectively, and 201Tl-SPECT may be useful in making the differentiation.
Journal ArticleDOI
Cerebral gliomas: prospective comparison of multivoxel 2D chemical-shift imaging proton MR spectroscopy, echoplanar perfusion and diffusion-weighted MRI
Dewen Yang,Yukunori Korogi,Takeshi Sugahara,Mika Kitajima,Yoshinori Shigematsu,Luxia Liang,Yukitaka Ushio,M. Takahashi +7 more
TL;DR: Echoplanar diffusion, perfusion MRI and multivoxel proton MRS can offer diagnostic information, not available with conventional MRI, in the assessment of glioma grade in patients with histologically verified gliomas.
Journal Article
Comparison of 2D and 3D Digital Subtraction Angiography in Evaluation of Intracranial Aneurysms
TL;DR: Three-dimensional DSA, especially SSD, provided more detailed information for evaluating cerebral aneurysms than did standard 2D and rotational DSA.
