# Application of Differential Subsampling with Cartesian Ordering in Evaluating Left Ovarian Venous Reflux for Pretreatment Planning for Pelvic Venous Disorders

## TL;DR

This paper explores using DISCO-MRI as a non-invasive alternative to fluoroscopic venography for diagnosing ovarian vein reflux in chronic pelvic pain.

## Contribution

The study introduces and evaluates DISCO-MRI as a potential non-invasive diagnostic tool for pelvic venous disorders.

## Key findings

- DISCO-MRI showed 78.6% concordance with fluoroscopic venograms in 14 patients.
- The technique could serve as a non-invasive alternative to fluoroscopic venography.
- DISCO-MRI provides high-temporal and spatial-resolution vascular imaging without ionizing radiation.

## Abstract

The diagnosis of a common cause of chronic pelvic pain can be made by visualizing reflux in the ovarian veins. Fluoroscopic venography is the gold standard for diagnosing ovarian vein reflux, but it is an invasive technique that exposes patients to ionizing radiation. MRI, with its lack of ionizing radiation and capability of high-temporal and spatial-resolution vascular imaging, has the potential to provide similar diagnostic information. This retrospective report describes and assesses the utility of a dynamic contrast-enhanced MRI technique based on Differential Subsampling with Cartesian Ordering (DISCO)–MRI in 30 patients with chronic pelvic pain. Among the 14 patients who underwent both DISCO–MRI and fluoroscopic venograms, 11 (78.6%) exhibited concordant results, while 3 patients (21.4%) had discordant findings. These results suggest the potential of multiphasic contrast-enhanced DISCO–MRI as a non-invasive diagnostic tool for evaluating chronic pelvic pain.
