Conclusion
Our findings support the utilization to 3D-TSE in the broader context of patients undergoing investigation for known or possible IM, not just patients with known IM. The benefits of 3D-TSE outweigh its disadvantages. However, radiologists should be aware of the higher FP rate when using 3D-TSE, and we suggest a low threshold for supplementing the examination with 3D-GRE where findings are equivocal. This is particularly relevant in patients with a lower pre-test probability of IM and/or when the clinical implications of an incorrect diagnosis are greater. There may also be value routinely performing both 3D-TSE in 3D-GRE in some situations, for example on the first imaging investigation, and during the transition from 3D-GRE to 3D-TSE. Using both sequences in combination optimizes both sensitivity and specificity.
