Susceptibility-Weighted Imaging and Quantitative Susceptibility Mapping

For many years, gradient echo (GRE) imaging has played a major role in helping to create rapid, high-resolution, high-contrast, large flip angle T1-weighted images for both very short and longer echo times. Clinically, it has been used more with smaller flip angles to highlight T2* effects in order to look for blood products such as those that occur in hemorrhage. About 15 years ago, another form of gradient echo imaging referred to as …
