Perfusion Mismatch Analyzer (PMA)

Perfusion Mismatch Analyzer (PMA), developed by Kohsuke Kudo, M.D.(Advanced Medical Science Center, Iwate Medical University, Iwate, Japan), is a versatile free software for quantitative analysis of perfusion and diffusion imaging of cerebrovascular disorders. ASIST-Japan releases PMA on condition that it is used exclusively for researh purposes.

Procedure Guidelines for CT/MR Perfusion Imaging 2006
The purpose of this guideline, drafted by Joint Committee for the Procedure Guidelines for CT/MR Perfusion Imaging, is to establish concrete, evidence-based procedures for theexamination/analysis/evaluation of acute ischemic stroke. In addition, our intention is to reduce the technical differences in CTP/MRP examinations between institutions and tocontribute to the improvement in the prognosis of patients with acute stroke treated bythrombolytic therapy.

ASIST-Japan-recommended standard LUT (a-LUT) for perfusion color maps
ASIST-Japan recommends the use of the standard Lookup Table (a-LUT) for perfusion parameter color maps by MRI and CT (The original data created by Kohsuke Kudo, M.D., Department of Radiology, Hokkaido University, Japan). The a-LUT data are available for download from the links below.
