T2* is fine to scan the intervertebral discs. T2 is the better choice to show small spinal cord lesions like MS plaques. The echo time of a T2* sequence may be not long enough to give a good differentiation between the pathology and surrounding tissue.rnDifferent 'Multi Echo Data Image Combination' (MEDIC) techniques have been developed to enhance contrast and pathology detection, if available on the scanner this type of sequence is maybe also a good choice, but due to longer scan times and artifact problems it is best for axial slices.rn

We've heard that a million monkeys at a million keyboards could produce the complete works of Shakespeare; now, thanks to the Internet, we know that is not true.
