| 摘要 |
The present invention relates to a novel magnetic resonance image technique for imaging collateral circulation in a human body. In the present invention, source data of a dynamic susceptibility contrast enhancement perfusion-weighted image (DSC-PWI) is subjected to an image-post-processing and an image obtained through the image-post-processing is then compared with an image obtained by digital subtraction angiography (DSA), thereby imaging the collateral circulation. The method according to the present invention can non-invasively, rapidly and easily visualize and evaluate the collateral circulation. Therefore, the method can provide information, which is important for understanding, treatment strategy determination and outcome prediction of a disease generated due to angiostenosis or occlusion. |
