Conventional and magnetic resonance hysterosalpingography in assessing tubal patency

Abstract

Aim: Conventional and magnetic resonance hysterosalpingography in assessing tubal patency. Material and methods: 50 patients, age 20–40 years, for evaluation of tubal patency were included in the study. It includes patients referred for postoperative evaluation, following reversal of tubal ligation and recurrent spontaneous abortions. The examination was done on Day 7–Day 12 of the menstrual cycle.Under strict aseptic precautions, MRI‑compatible plastic HSG 5 ‑ F microcatheter with inflatable bulb was inserted into the lower uterine cavity. The bulb was inflated with 3 cc of distilled water and shifted to MRI scan 1.5 Tesla [GE] machine. T2 W (TR: 7120 ms, TE: 90 ms, flip angle 900, slice thickness 5 mm, matrix 256 × 256) axial, sagittal, and coronal sequences were done. Results: The comparative sensitivity, specificity, positive predictive value [PPV], negative predictive value [NPV], and diagnostic accuracy of MR HSG and cHSG were 100%, 99.08%, 100%, 97.5%, and 99.75%, respectively, and those of MR HSG and DL were 100%, 93.73%, 87.21%, 100%, and 96%, respectively. The Kappa agreement between MR HSG and cHSG was excellent [0.97] and a McNemar test value of 1 showed no statistical difference between the two procedures. Conclusion: MR HSG is a novel upcoming investigation method with very few pioneering studies at both national and international levels. This study is distinctive in the sense that it explores the utility and feasibility of HSG being done using MRI.
