The investigators hypothesized that Macrovascular Flow imaging could contribute to 2D power Doppler and 3D power Doppler in depicting fibroid vascularity. However, data concerning the feasibility and reproducibility of Macrovascular Flow imaging is lacking. Therefore the purpose of our study was to determine 1) the reproducibility of Macrovascular Flow imaging, 2) its correlation with 2D and 3D power Doppler, and 3) penetration depth, in order to investigate the added value for daily clinical practice.

reproducibility by inter- and intraobserver agreement
The primary outcome was calculated by the assessment of intercorrelation coefficient (ICC) and its 95% confidence interval (CI) using a two-way mixed model. An ICC value of 0.75-1.00 indicates a good to excellent agreement(19). Bland-Altman plots showed the distribution of data.
Time frame: Day 1
penetration in centimeters
The penetration was measured along the direction of the ultrasound wave, from the probe to the deepest ultrasound signal visible, both for Microvascular Flow and power Doppler. Differences in ordinal data was tested by Mann Whitney U, non-normal continuous data by Wilcoxon rank test and normally distributed continuous data by a one sample t-test.
