When does female breast tissue begin to develop beyond male breast tissue?
puberty
Which technique uses vocal vibrations to differentiate benign and dense breast tissue?
vocal fremitus
With the ABC and 123 method, explain what the letter and number tell us about a breast mass.
ABC: depth, A closest to nipple, C closest to muscle
123: distance, 1 closest to nipple, 3 furthest from nipple
Name 5 indications for a breast ultrasound.
dense breasts, mammo finding, palpable mass, clinical finding, axillary nodes, pain, follow up
What part of the breast has the most breast tissue?
UOQ
Which germ layer is the nipple formed from?
mesoderm
In breast sonography, why are transverse and sagittal scanning planes not utilized?
To follow the direction of the lobes in the breast
Name 3 parenchymal elements of the breast.
acini, lobules, lobes, ducts
What is it called when there are 2 or more masses less than 5 cm away from each other?
multifocal
What is the smallest functional unit of the breast?

light pressure, power doppler
What are the two types of malignant nipple discharge and what do they each indicate?
blood: invasive cancer cells in ducts
clear: proliferation of ductal epithelial cells
Which sonographic artifact occurs with silicone implants?
propagation speed, sound travels through silicone slower than soft tissue, posterior structures appear deeper than they actually are
