Flow related enhancement とは
WebDec 1, 2012 · 2) Paradoxical or flow-related enhancement seen on the first or last image of a sequence is due to signal intensity from unsaturated protons moving into the interrogated field. 3) Vascular and CSF flow can create artifacts due to the change in the location of excited and/or unexcited hydrogen protons. WebFlow-related enhancement can potentially provide positive contrast of diagnostic value in terms of anatomic depiction of vascular detail as well as physiologic characterization of blood flow. The authors have used a single-section, selectively irradiated, spin-echo pulse sequence to maximize flow-related enhancement within a variety of ...
