Sample text

The image on the right is the elastogram. A black and white color scale is used, with black corresponding to the stiffest tissue. 4, suggestive of a malignancy. A copy or shadow function is used to “duplicate” the measurement on the B-mode image onto the same location on the elastogram (yellow lines). This function is helpful to confirm the location of a lesion in the elastogram or vice versa. Fig. 10 Strain elastogram of a biopsy-proven benign fibroadenoma (red arrows). The lesion is well circumscribed with lobulations and taller than wider in the B-mode image, classifying the lesion as a Breast Imaging–Reporting and Data System 4B (BI-RADS 4B) lesion.

27). The bull’s-eye cyst pattern can be seen with lesions that appear solid and suspicious on B-mode imaging. 48 These lesions can be aspirated to confirm that the lesion resolves after aspiration. If core biopsies are performed notifying the pathologist the lesion is a complicated cyst as opposed to a solid mass will lead to better pathology imaging correlation. If the pathologist is told the lesion is solid, the report may not mention that a cyst wall is present, which may suggest that the suspected solid lesion is not in the specimen, leading to stress on the radiologist and the patient.

If the material within the lesion is very viscous such as a hematoma or mucin the bull’s-eye artifact will not occur. This is an example of a mucinous malignancy that does not demonstrate the bull’s-eye pattern (dotted line). Fig. 28 In some systems the bull’s-eye pattern is not observed for cystic lesions, but a blue, breen, red (BGR) pattern is observed. This is an example of this artifact in a simple cyst using the color map of blue to indicate stiff (a) and on a gray scale (b). 2 Blue/Green/Red (BGR) Artifact Some systems have a different artifact that occurs in cysts (▶ Fig.
