Utilizing of gray scale &unenhanced power Doppler ultrasound in differentiation of malignant & begin palpable breast lesions :Does vascularity in power Doppler correlate with lymph node status?

الملخص

US (ultrasound) is currently one of the main diagnosing breast disease .In gay scale US there are typical characteristic features of benign & malignant mass. Used of power Doppler has also been exploited in aiding the benign & malignant differentiation of solid masses. 1.The purpose of this study was to investigate sensitivity of gray scale US features in differentiating benign from malignant solid breast masses .
2.To evaluate the role of power Doppler imaging to differentiate benign & malignant solid breast masse & how power Doppler findings correlate with lymph node involvement . The study involved 55 female present with breast lesion , in Department of Diagnostic radiology in AL Dewanyia teaching hospital refered from breast centre in period July 2008 – January 2010 , the inclusion criteria was the presence of breast lesion, undergo surgery , exclusion criteria female with breast lesion & refused surgery. Tempt was made to categories lesions as benign , malignant by using US criteria & power Doppler correlate this findings with pathological results .
A total of 55 female patients with solid breast mass. Mean age was (44year ) . Size of breast lesion range from 1-6cm , most common sit of the tumor was upper lateral quadrant in both malignant & benign breast mass. Comparison of US & histological findings was made , this enable to calculate sensitivity (90%) of gray scale ultrasound , sensitivity of power Doppler was 70% & majority of malignant tumors (78%) that demonstrate vascularity in power Doppler showed axillary lymph node invasion . Power Doppler sonography should be considered together with the established criteria in gray scale ultrasound. Further study is indicated by using more advanced procedures like enhanced power Doppler US(using levovist) to increase sensitivity of US.
