How is dark blood MRI accomplished, and why is it used?
Dark blood imaging is an MRI technique whereby the blood signal intensity is suppressed; this can be done with spin echo or inversion recovery imaging. By reducing the signal from blood, myocardial tissue and vessel walls stand out from the background and can be seen in great detail. Dark blood imaging techniques are useful for detailed analysis of myocardial morphology and composition, cardiac anatomy, and vascular anatomy.
