Magnetic resonance imaging (MRI) is an essential non-invasive technique for diagnosing deep infiltrating endometriosis (DIE). Published studies have explored the value of high-resolution fat-suppressed 3D T1-weighted (T1w) and 3D T2-weighted (T2w) MRI in this topic. However, research on the fusion of these sequences in a merged ‘PET-scanner-like’ multiplanar reconstruction (Fusion 3D T1/T2) is still lacking.Our primary objective was to assess whether the diagnostic accuracy of Fusion 3D T1/T2 wa…
