Demer et al reported on an interesting study comparing the accuracy of transvaginal ultrasound (TVS) and magnetic resonance imaging (MRI) for local staging in women with endometrial cancer.1 This study concluded that both techniques have a similar diagnostic accuracy for detecting deep myometrial infiltration and cervical invasion.

The main strength of this study is its prospective design with gynecologist and radiologist blinded each other to their respective assessment. The results of this study are relevant for they confirm data from two previous meta-analyses analyzing studies comparing TVS and MRI for detecting myometrial infiltration2 and cervical invasion3 in patients with endometrial cancer. These findings are clinically important since, as the authors state in their manuscript, TVS is cheaper and worldwide available than MRI. This fact is very important when considering the preoperative assessment of women with endometrial cancer in low- and mid-income countries, where financial and facility resources are scanty.
