Although the difference in diagnostic performance between oblique and true axial T2WI for the entire study population was only significant for R1 ( p = 0.027) and not for R2 ( p = 0.153), in the subgroup with tumors > 2.5 cm, the difference was statistically significant for R1 ( p = 0.046) and borderline significant for R2 ( p = 0.086).
