Abstract
AimTo elucidate the hemodynamics of the uterine artery myomas by use of Doppler ultrasound and biomagnetic measurements.MethodTwenty-four women were included in the study. Sixteen of them were characterised with large myomas whereas 8 of them with small ones. Biomagnetic signals of uterine arteries myomas were recorded and analyzed with Fourier analysis. The biomagnetic signals were distributed according to spectral amplitudes as high (140–300 ft/√Hz), low (50–110 ft/√Hz) and borderline (111–139 ft/√Hz). Uterine artery waveform measurements were evaluated by use of Pulsatility Index (PI) (normal value PI < 1.45).ResultsThere was a statistically significant difference between large and small myomas concerning the waveform amplitudes (P < 0.0005) and the PI index (P < 0.0005). Specifically, we noticed high biomagnetic amplitudes in most large myomas (93.75 %) and low biomagnetic amplitudes in most small ones (87.5 %).ConclusionIt is suggested that the biomagnetic recordings of uterine artery myomas could be a valuable modality in the estimation of the circulation of blood cells justifying the findings of Doppler velocimetry examination.

Summary
Uterine myomas irrespective of whether they are small and asymptomatic (as in the postmenopausal women) or large and symptomatic (as in premenopausal women) considerably affect uterine artery blood flow velocity. Benign uterine leiomyomas are usually recognized with gray-scale ultrasonography, but may sometimes be difficult to differentiate from solid ovarian tumours. Doppler ultrasound is a diagnostic modality widely applied in obstetrics and gynecology [1,2,3,4,5]. It has been used to characterize pelvic tumours, and transvaginal color and spectral Doppler examinations have been suggested to enable discrimination between benign and malignant adnexal masses [6,7,8]. Circulation of benign uterine leimyomas has been described by use of Doppler velocimetry. Some authors have tried to correlate the myoma volume and the (page number not for citation purposes)
