Sonographers' self-reported visualization of normal postmenopausal ovaries on transvaginal ultrasound is not reliable: results of expert review of archived images from UKCTOCS.

The article presents a study evaluating the self-reported visualization rate (VR) of ovaries by sonographers during transvaginal sonographic (TVS) examinations in an effort to develop software that would automatically measure VR. Using data from the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS), it found that sonographers may mistake other biological structures for normal ovaries and concludes that quality control (QC) metrics based on self-reports are unreliable.
