KOHAN, A.A et al. Diagnostic performance of magnetic resonance hysterosalpingography: initial results Abstract. Rev. argent. radiol. [online]. 2017, vol.81, n.1, pp.3-11. ISSN 1852-9992.

Objective: To determine the diagnostic performance of magnetic resonance hysterosalpingography (MRHSG) using laparoscopic chromotubation as a method of reference. Materials and methods: Twenty-two patients were included. The MRHSG was performed in a 1.5 Tesla MR scanner. Afterwards, patients underwent laparoscopic chromotubation. MR images were examined by two trained radiologists, and tubal patency was determined by consensus. A descriptive analysis was carried out, as well as an analysis of the diagnostic performance. Results: MRHSG had a 91% success rate. Exam duration of the examination was 49ą15min, with an injected volume 26ą 16cc, and pain scale 30ą 19 out of 100. Sensitivity and specificity of MRHSG was 100% for global and left Cotte, and 25% and 93.3% for right Cotte, respectively. Only 2 minor and no major complications were observed. Discussion: The initial results of MRHSG have shown high sensitivity and specificity. Even though other studies have analysed the potential of MRHSG with good results, the use of a flawed reference standard left a margin for a reasonable doubt as regards its true potential, thus preventing a solid evidence based recommendation. Nevertheless, if our results are compared to those published, a high level of agreement is observed in that positive spillage is correctly diagnosed with specificities near or at 100%. Conclusion: MRHSG is a feasible and safe alternative to conventional or virtual HSG, ultrasound-hysterography and chromotubation.
