| Research Abstract |
Theaimofthisresearchisadevelopmentofnewanalysisofcardiac muscle contraction using diffusion weighted magnetic resonance images (DWI). The DWI of cardiac muscle is loss signal during contraction. The reason was not clear. However the water trasfer in the tissue will affect this signal loss in DWI. The stress of water transfer in the tissue makes visocosity, so I named it “MR Viscography”. The variety of segmented ADCs had good correlation to other report. The MR Viscography is the fast method that may give a information of degree of cardiac muscle contraction.
