Color Doppler recording and Doppler spectrogram ultrasonography
The rates of visualization of the uterine spiral arteries for Groups 2 and 3 were significantly higher after the treatment than before (respectively, Success ratios of Doppler-assisted visualization of uterine spiral arteries before and after the therapy.The data are presented as raw counts and % rates, subject to McNemar’s binomial test.A relationship between endometrial thickness and local microcirculatory hemodynamics was specified statistically. Significant associations of endometrial thickness parameters with angle-independent Doppler indices were revealed, including negative (inverse) correlations between M-mode echo and pulsatility index (
