Terms, definitions and measurements to describe the sonographic features of adnexal tumors: a consensus opinion from the International Ovarian Tumor Analysis (IOTA) group

Comparison of ‘pattern recognition’ and logistic regression models for discrimination between benign and malignant pelvic masses: a prospective cross validation

“…The fact that 47% of the malignant tumors in the Tailor study 4 were classified as unilocular vs. none in our study and only 6% in the Timmerman study 5 , and the fact that the frequency of papillary projections in benign and malignant tumors differed very much between our study and the others 4,5 , support this, because it is highly unlikely that these differences are to be explained exclusively by true differences in tumor morphology. To facilitate the process of defining ultrasound findings characteristic of various types of tumor, and to make comparison between studies meaningful, unequivocal definitions of the ultrasound terms used are necessary 15 .…”

Differentiation of Benign from Malignant Adnexal Masses by Functional 3 Tesla MRI Techniques: Diffusion-Weighted Imaging and Time-Intensity Curves of Dynamic Contrast-Enhanced MRI

“…papillary projections and nodularity), necrosis, hemorrhage, or regions of intense enhancement after IV contrast. However, there is considerable overlap between benign and malignant masses in the mentioned parameters (Timmerman et al, 2000;Katayama et al, 2002;Thomassin-Naggara et al, 2009). Researchers in different studies have investigated more recent functional MR techniques such as DCE-MRI, DWI, and its quantitative derivative, ADC in distinguishing benign from malignant adnexal masses (Katayama et al, 2002;Takeuchi et al, 2010;ThomassinNaggara et al, 2011;Li et al, 2012;Zhang et al, 2012).…”

The ‘daughter cyst sign’: a sonographic clue to the diagnosis of fetal ovarian cyst

“…Using these criteria, Brandt et al 9 found that 92% of newborns who underwent surgery for suspected torsion of the ovary presented prenatal ultrasound characteristics of a complicated cyst. Furthermore, there are no features that would predict the occurrence of this complication 10 .…”
