In various embodiments, the present invention teaches systems and methods for using T1-weighted black-blood MR imaging, with which a CVT can be well isolated from the surrounding tissues due to the signal suppression of flowing blood. In some embodiments, the invention teaches using black-blood imaging (3D variable-flip-angle turbo spin-echo acquisition) to directly visualize thrombi. In certain embodiments, the invention teaches using T1 weighted image contrast and isotropic sub-millimeter spatial resolution for accurate detection and staging of thrombi. In various embodiments, the invention allows for the detection of chronic thrombosis recanalization.
