“…Only four publications used 3.0T but suggested promising results [11, 16, 25, 26]. At 3.0T, improved signal-to-noise ratio results in the acquisition of high-spatial resolution images and accurate depiction of all locations of DPE [11, 16, 25]. However, there is increased image heterogeneity at 3.0T when compared to 1.5T, which can have a negative effect on the fat-saturation techniques routinely utilised in the evaluation of endometriosis [16, 27].…”

European society of urogenital radiology (ESUR) guidelines: MR imaging of pelvic endometriosis

et al. 2016

View full text Add to dashboard Cite

Endometriosis is a common gynaecological condition of unknown aetiology that primarily affects women of reproductive age. The accepted first-line imaging modality is pelvic ultrasound. However, magnetic resonance imaging (MRI) is increasingly performed as an additional investigation in complex cases and for surgical planning. There is currently no international consensus regarding patient preparation, MRI protocols or reporting criteria. Our aim was to develop clinical guidelines for MRI evaluation of pelvic endometriosis based on literature evidence and consensus expert opinion. This work was performed by a group of radiologists from the European Society of Urogenital Radiology (ESUR), experts in gynaecological imaging and a gynaecologist expert in methodology. The group discussed indications for MRI, technical requirements, patient preparation, MRI protocols and criteria for the diagnosis of pelvic endometriosis on MRI. The expert panel proposed a final recommendation for each criterion using Oxford Centre for Evidence Based Medicine (OCEBM) 2011 levels of evidence.Key Points• This report provides guidelines for MRI in endometriosis.• Minimal and optimal MRI acquisition protocols are provided.• Recommendations are proposed for patient preparation, best MRI sequences and reporting criteria.Electronic supplementary materialThe online version of this article (doi:10.1007/s00330-016-4673-z) contains supplementary material, which is available to authorized users.

“…The bowel is the most common location of extragenital endometriosis, and bowel endometriosis occurs in up to 37% of women with DIE. Although the rectosigmoid colon is the most common location (52%-72%), endometriotic implants can also be found in the small bowel, especially in the terminal ileum (4.1%-16.9%) (10).…”

“…Pelvic endometriosis has a somewhat predictable and repetitive distribution practice and allows a comprehensive evaluation for patient counseling and preoperative planning. The pelvic cavity, abdominal wall, small bowel, appendix, and inguinal area can be evaluated with transvaginal ultrasonography (US) after bowel preparation, high-resolution US with a linear transducer, and magnetic resonance (MR) imaging (4,7,(10)(11)(12)(13). Thoracic endometriosis can be assessed with conventional radiography, thin-section computed tomography (CT), and thoracic MR imaging (10,14).…”

Atypical Sites of Deeply Infiltrative Endometriosis: Clinical Characteristics and Imaging Findings

et al. 2018

View full text Add to dashboard Cite

Endometriosis is defined as the presence of endometrial tissue that is located outside the uterine cavity and associated with fibrosis and inflammatory reaction. It is a polymorphic and multifocal disease with no known cure or preventive mechanisms. Patients may be asymptomatic or may experience chronic pelvic pain, dysmenorrhea, dyspareunia, or infertility. The pelvic cavity is the most common location for endometriotic implants, which usually affect the retrocervical space, ovaries, vagina, rectosigmoid colon, bladder dome, and round ligaments. Atypical endometriosis is rare and difficult to diagnose. The most common atypical locations are the gastrointestinal tract, urinary tract, lung, umbilicus, inguinal area, breast, and pelvic nerves, as well as abdominal surgical scars. Gastrointestinal lesions are the most common extragenital manifestation, and the diaphragm is the most frequent extrapelvic site. The catamenial nature of the symptoms (occurring between 24 hours before and 72 hours after the onset of menstruation) may help suggest the diagnosis, but imaging by specialists is fundamental to evaluation. Depending on the area affected, radiography, ultrasonography, thin-section computed tomography, or magnetic resonance imaging can be used to assess suspected lesions. Because isolated extragenital endometriosis is rare, concomitant evaluation of the pelvic cavity is mandatory. Surgical excision is the only therapeutic option for definitive treatment, and comprehensive disease mapping is necessary to avoid residual disease. The authors review atypical locations for endometriosis and emphasize the most appropriate imaging protocols for investigation of various clinical manifestations. Online supplemental material is available for this article. RSNA, 2018.

“…4a). In these cases, the use of contrast media allows a better distinction between the lesion and the normal bowel wall (51). The involvement of the anterior wall of the rectum and sigmoid tract creates a typical "mushroom" aspect of the infiltrating fibrotic plaque on T2-weighted images (Fig.…”

Bowel Endometriosis: Preoperative Diagnostic Accuracy of 3.0-T MR Enterography—Initial Results

Abstract: These results show 3.0-T MR enterography is accurate in the preoperative diagnosis and mapping of bowel DIE lesions located above the rectosigmoid junction. Online supplemental material is available for this article.
