Figure 1. Biopsy Proven Simple Breast Cyst. The image on the left is a conventional ultrasound image. The image on the right was acquired at the same time with the same signals and is the elasticity image. The Elasticity image has a "bull's eye" appearance with the lesion black (yellow arrows) with a bright spot in the center (green arrow) and a bright spot behind the cyst (red arrow). We have found that both simple cysts and benign complex cysts have this appearance. Also note the size of the cyst is smaller on the elasticity image which are results suggest this is a benign lesion.

Figure 2. Biopsy Proven Invasive Ductal Carcinoma. The image on the left is a conventional ultrasound image. The image on the right was acquired at the same time with the same signals and is the elasticity image. The lesion in the elasticity image is much larger than the image in the conventional ultrasound, which we have found to correspond to a malignant lesion.

Figure 3. Biopsy Proven Benign Fibroadenoma. The image on the left is a conventional ultrasound image. The image on the right was acquired at the same time with the same signals and is the elasticity image. The size of the fibroadenoma is smaller on the elasticity image when compared to the conventional ultrasound image. Our initial results suggest this decrease in size on the elasticity image occurs in benign lesions.

Figure 4. The image on the left is the conventional ultrasound image. The image on the right is the elasticity image. The lesion is a biopsy proven invasive ductal carcinoma of the breast. Note the lesion is larger on the elasticity image than the conventional ultrasound image, which by our preliminary results would highly suggest the lesion is malignant.
