Value of ultrasound in diagnosing ductal carcinoma in situ / 肿瘤研究与临床

ABSTRACT

Objective To evaluate the value of ultrasound in diagnosing ductal carcinoma in situ (DCIS). Methods The sonographic characteristics of 12 DCIS which were confirmed by pathology were analyzed retrospectively. Results The ultrasound image of DCIS could be divided into four types;the solid mass nodule, mammary dysplasia, mix mass nodule, the dilated duct type. Micro calcification had high incidence rate. Ultrasonic diagnosis accordance rate was 50.0 %. On molybdenum target mammograms, the tumor appeared as a cluster of calcified spots in 8 cases, and the accuracy rate of diagnosis of was 66.7 %.Conclusion There are no typical characters of DCIS in ultrasound image. However, some characteristics are suggestive and can help to differentiate them from the benign tumors, such as small nodule, irregular shape,obscure boundary, and microcalcification. When sonography combine with molybdenum target mammography,the accuracy rate of diagnosis will be improved.
