 A 55-year-old female was recently diagnosed with an invasive ductal carcinoma of two masses in the left breast. Mass A is 3.1 cm in greatest diameter and is located in the left upper outer quadrant at posterior depth. Mass B is 4 cm in greatest diameter and located in the left lower inner quadrant at middle depth. Which statement is correct?

A. The patient is a candidate for whole-breast radiation therapy.

B. The patient is a candidate for breast conserving surgery.

C. The findings are suspicious for multifocal invasive breast cancer on MRI.

D. The findings are suspicious for multicentric invasive breast cancer on MRI.

B. edema

C. architectural distortion

D. mass

E. axillary adenopathy

84
 Shown is a spot magnification view of axillary lymph nodes along with ultrasound images taken of the left axillary region. These lymph nodes were seen on ultrasound as well. If this is a new finding in a patient that has a history of ipsilateral breast cancer, what is the BI-RADS category assessment?

A. BI-RADS 2

B. BI-RADS 3

C. BI-RADS 4

D. BI-RADS 6

85
 Shown is a breast MRI image demonstrating a mass in the right breast at 7 o’clock at a middle depth. The time–intensity kinetic curve showed a type I curve. Which of the following is the most appropriate next step?

A. Recommend a follow-up 6-month breast MRI to document stability.

B. The mass should be categorized as BI-RADS 2, and continued risk-appropriate screening should be recommended.

C. Biopsy should be performed despite benign kinetics.

D. The study is limited due to suboptimal technique and should be repeated.

86
 Based on the diagnostic ultrasound images, which one of the following is the most appropriate BI-RADS category assessment?
