Technical Consideration

These two MR images illustrate two of the many MR techniques used to examine the thoracic and cardiovascular system: “black blood” and “white blood” imaging techniques, named for the appearance of flowing blood on the image. There are a number of ways in which “black blood” images may be created, but these techniques have in common the lack of significant signal associated with flowing blood—hence, the vessels and cardiac chambers appear black. “White blood” sequences are often used for functional analysis and, although the bright signal within the vessels and cardiac chambers gives the impression that intravenous contrast has been injected, these imaging sequences do not require the use of intravenous contrast to generate signal within the vascular system.
