Histopathology dating someone not attracted toWebbIn regions of a vessel where the flow is too slow or turbulent to produce unambiguous signal changes, the phase image will still show movement. Therefore the phase image provides a rigorous method of distinguishing between signal arising from a condition of no flow (for example, thrombus) and signal caused by slow or turbulent flow. bj\u0027s stuck a package of friendship

"WebbFirst pass computed tomography (CT) and magnetic resonance (MR) imaging are used routinely, where the image acquisition is timed to the arrival of contrast in the proximal unaffected aorta. Delayed phase imaging is difficult to refine because flow rates in the false lumen are often very slow and highly variable between patients. " - Slow flow vs thrombus mri
