Abstract:
Objective To compare the display effect of contrast enhanced MR angiography (CE-MRA) and CTA in evaluating blood supply of early stage cervical cancer.Methods CE-MRA and CTA before the operation of 30 patients with pathologically confirmed early stage cervical cancer were analyzed retrospectively.The origins and continuity of bilateral uterine arteries and the conspicuity of bilateral decending branch of uterine arteries between CE-MRA and CTA were evaluated.Results Fifty uterine arteries could classify as origins clearly visible and vessels clearly visible without discontinuity,5 uterine arteries as origins clearly visible but vessels unclearly visible on both CEMRA and CTA.Both CE-MRA and CTA were conformed well in evaluating the origin and continuity of uterine arteries (Kappa=0.80,P＜0.05).The conspicuity of decending branches for CE-MRA was 55.00％ (33/60),which was lower than that of CTA (73.33％ [44/60]),which had statistically significant difference between CE-MRA and CTA (x2 26.22,P＜0.01).Conclusion For early stage cervical cancer,CE-MRA and CTA can both provide a good performance in evaluating the origin and continuity of uterine arteries,CTA reveals advantage over CE MRA in detecting conspicuity of decending branch of uterine arteries.
