Although the use of contrast is not heavily spread in ultrasound‚ through studies it has been noted that contrast use in sonography has proven to be helpful in diagnostic imaging. CEUS which is short for contrast enhanced ultrasonography in some cases has been able to distinguish a variety of issues‚ from determining a benign or malignant lesion‚ to determining muscle injuries. According to Sconfienza‚ malignant tumors are presented with several sonographic appearances including the following “rich
