“…Data on pelvic anatomy as well as flow disturbances are also useful in developing the details of the embolization procedure. MR is reproducible, less expensive than conventional venography, and non-irradiating in these young female patients [20,29,40,41].…”

It is estimated that the problem of Chronic Pelvic Pain (CPP) may concern up to 24% of women. Unfortunately, very often, despite extensive diagnostics, the cause of CPP remains unknown. The pathophysiology of CPP could be explained to a large extent by the occurrence of Pelvic Venous Disorders (PVD). Although pelvic venography is still considered the gold standard for the diagnosis of PVD, non-invasive diagnostic imaging techniques seem to be instrumental in the initial identification of patients with PVD. This literature review aimed to analyse and evaluate the usefulness of non-invasive diagnostic imaging techniques like Transvaginal Ultrasonography, Transabdominal Ultrasonography, Magnetic Resonance and Computed Tomography in the diagnosis and identification of patients with PVD. Forty-one articles published between 1984 and 2023 were included in this literature review. Based on this literature review, we conclude that the clinical application of non-invasive diagnostic techniques in the diagnosis of PVD seems to be very promising. Future studies investigating the role of non-invasive diagnostic imaging techniques in the diagnosis of PVD are required.

“…In this model, pursuing a body‐weight normalized approach would risk, in the pigs of smaller size, dilution of the small dose of contrast agent within the pulmonary vasculature following injection. While additional utility of dynamic MRA, beyond stenosis evaluation, has been shown in other settings (34–37), analogous advantages relative to static MRA have not been described in renal MRA.…”

Purpose: To establish the minimum dose required for detection of renal artery stenosis using high temporal resolution, contrast enhanced MR angiography (MRA) in a porcine model. Materials and Methods:Surgically created renal artery stenoses were imaged with 3 Tesla MR and digital subtraction angiography (DSA) in 12 swine in this IACUC approved protocol. Gadobutrol was injected intravenously at doses of 0.5, 1, 2, and 4 mL for time-resolved MRA (1.5 Â 1.5 mm 2 spatial resolution). Region of interest analysis was performed together with stenosis assessment and qualitative evaluation by two blinded readers.Results: Mean signal to noise ratio (SNR) and contrast to noise ratio (CNR) values were statistically significantly less with the 0.5-mL protocol (P < 0.001). There were no statistically significant differences among the other evaluated doses. Both readers found 10/12 cases with the 0.5-mL protocol to be of inadequate diagnostic quality (k ¼ 1.0). All other scans were found to be adequate for diagnosis. Accuracies in distinguishing between mild/insignificant (<50%) and higher grade stenoses (>50%) were comparable among the higher-dose protocols (sensitivities 73-93%, specificities 62-100%). Conclusion:Renal artery stenosis can be assessed with very low doses ($0.025 mmol/kg bodyweight) of a high concentration, high relaxivity gadolinium chelate formulation in a swine model, results which are promising with respect to limiting exposure to gadolinium based contrast agents.

“…Furthermore, time resolved magnetic resonance venography may also be useful to depict retrograde flow in the dilated ovarian vein or veins filling the varices (29,30). However, it should be noted that presence of dilated gonadal veins and pelvic varices may be seen in asymptomatic women, particularly in those who have had prior pregnancy, and therefore the diagnosis of pelvic congestion syndrome can only be made definitively when a clinical history of chronic pelvic pain is also present.…”
