Crosstalk artefacts appear as dark signal lines on MR images that occur due to imperfect multi-slice settings. There is still a good deal of emergence of crosstalk artefacts on T1 of SE and FSE sequence with interleaved slice acquisition methods. This study aims to determine the differences and the optimal value of reduction of crosstalk artefacts against changes in TR on T1 between SE and FSE sequences in interleaved slice acquisition methods. The experiment was carried out by scanning the water phantom with a variation of TR 500ms, 600ms, and 700ms in SE and FSE sequences. An assessment of the reduction of crosstalk artefacts was carried out using SNR values. There is a significant difference in the reduction of crosstalk artefacts between SE sequences and FSE on T1 (p-value = < 0.001). The reduction of crosstalk artefacts in SE sequences with TR values of 600ms and 700ms respectively, were 22.2% and 37.7%. Whereas the FSE sequences were 28.3% and 56%. Optimal crosstalk artefact reduction occurs in FSE sequences of T1 (56%). It is intended to use FSE sequences with TR 700ms on T1 if there are overlapping slices so that the crosstalk artefacts that occur will be reduced optimally.
