Clinical prediction rules in trauma imaging: who, how, and why?

abstract：:Both ultrasonography and x-ray mammography were performed on a male patient who had breast carcinoma. While the x-ray mammographic features were highly suggestive of malignancy, the sonographic findings were subtle. Because of the technical difficulties associated with x-ray mammography of the male breast, ultrasound ...
