摘要： The technology herein provides a dark blood delayed enhancement technique that improves the visualization of subendocardial infarcts that may otherwise be disguised by the bright blood pool. The timed combination of a slice-selective and a non-selective preparation improves the infarct/blood contrast by decoupling their relaxation curves thereby nulling both the blood and the non-infarcted myocardium. This causes the infarct to be imaged bright and the blood and non-infarct to both be imaged dark. The slice-selective preparation occurs early enough in the cardiac cycle so that fresh blood can enter the imaged slice.

摘要： Methods and systems for obtaining intravascular magnetic resonance images of blood flow are disclosed. In preferred forms, a train of radio frequency (RF) pulses is produced by an intravascularly introduced RF transmitter positioned in proximate location to the blood flow so as to create a continuous stream of coherently excited protons of the blood flow. The coherently excited protons of the blood flow are sampled as the protons freely precess while flowing through a region of three dimensional space unaffected by the ongoing intravascular RF excitation. An image of the sampled coherently excited protons may then be constructed.

摘要： A system automatically calculates optimal protocol parameters for dark-blood (DB) preparation and inversion recovery. The system automatically determines pulse sequence timing parameters for MR imaging with blood related signal suppression. The system comprises an acquisition processor for acquiring data indicating a patient heart rate. A pulse timing processor automatically determines an acquisition time of an image data set readout, relative to a blood signal suppression related magnetization preparation pulse sequence, by calculating the acquisition time in response to inputs including, (a) the acquired patient heart rate, (b) data indicating a type of image contrast of the pulse sequence employed and (c) data indicating whether an anatomical signal suppression related magnetization preparation pulse sequence used has a slice selective, or non-slice selective, data acquisition readout.
