Endometriosis is a common gynaecological presentation seen in clinical practice with uncertain aetiology. Endometriosis can be broadly categorised into its location of involvement, whether they are superficial or within the deep spaces.1 However more significantly it can be recognised by their depth of infiltration, whether they are embedded with depth greater than 5mm (deep), or less (superficial). Deep infiltrative endometriosis is known for its complexity in different stages of clinical practice. There is often delay in diagnosis with significant debilitating symptoms and multiple hospital consultations,...

Study design: Retrospective cohort study Period: January to December 2017. Study population: All patients discussed at Endometriosis MDT in a tertiary referral hospital centre, n= 85. 35 patients excluded due to non-surgical management or loss to follow up. Procedure: Local MRI protocol adhered. Patient prep - bladder emptying and administration of anti-peristaltic agent (Buscopan). Image Sequences - T2 (Sag, Axial, Axial FATSAT), T1 (Axial, Axial FAT SAT, Sag FAT SAT), TRUFI coronal and T1 VIBE FATSAT Sag. Comparative analysis of MRI findings performed using surgical...

A total of 50 patients were deemed adequate for the study with patients excluded due to the lack of surgical management. The mean duration between MRI to surgery is 290 days.

While laparoscopic remains the gold standard in identifying the location of these lesions, there is renewed interest in MRI in providing concise preoperative imaging in particular in identifying deep infiltrative pelvic endometriosis in order to optimize the appropriate surgical technique to maximise chances of a good outcome, with early detection and involvement of specialist colorectal team in its pre-operative planning. This in turn has likely led to a significant time between MRI imaging to time of surgery. While this could be thought to cause further...
