摘要
Prospective study in 31 women with T1 breast cancers (24 invasive breast cancers and 7 in situ breast cancers) consisting of no vessel or a single vessel as demonstrated by color Doppler ultrasound (US), CDUS, who received dynamic enhanced magnetic resonance (eMRI). The flow parameters measured by CDUS and dynamic eMRI were statistically correlated and analyzed in distinguishing the invasive or in situ breast cancers and in predicting the axillary nodal status. All of the cancers were enhanced by dynamic eMRI; however, only 22 had color flow demonstrated by CDUS; 9 invasive cancers had metastasized to the lymph node. There was no correlation between the flow indices on CDUS and signal intensities on dynamic eMRI. Patterns of the signal-time curves of invasive and in situ cancers were statistically distinguishable and the correlation between lymph node status and peak systolic velocity was statistically significant. Hemodynamic parameters measured by CDUS and dynamic eMRI carry independent values in evaluating T1 breast cancers. With the knowledge of hemodynamic information, a more comprehensive approach to the treatment of these cancers can be achieved. (C) 2003 World Federation for Ultrasound in Medicine Biology.
