T2-weighted imaging is a structural technique with contrast dominated by signal decay from interactions between water molecules (T2 relaxation times). Image intensity is primarily related to pathology, with relatively subtle signal differences between grey and white matter. T2-weighted images depict alterations to tissue compartments typically associated with pathology (e.g., white matter lesions).

After early piloting, a standard T2/PD-weighted acquisition was dropped due to a combination of factors such as overall value and timing practicalities.
