The assessment of spectral Doppler parameters in uterine arteries of patients with locally advanced squamous cell cervical cancer.

In patients with locally advanced cervical cancer of uterine arteries, assessment of PSV but not EDV, RI or PIcan be helpful in differentiating infiltrated from non-infiltrated vessels. In this group of patients, radiotherapy decreasesPSV, but not EDV, RI or PI values in uterine arteries. An observation conducted from the onset of radiotherapy to end ofthe follow-up in uterine arteries reveals that PI, but not RI, PSV or EDV, is different in infiltrated and non-infiltrated vessels.
