- What does the CC view stand for in mammography?
- Craniocaudal
- What does the MLO view stand for in mammography?
- Mediolateral oblique
- What does PNL stand for in mammography positioning?
- Posterior nipple line
- On a well-positioned CC view, how close should the PNL measurement be to the MLO PNL measurement?
- Within 1 cm
- What is the typical angle range used for the MLO projection?
- About 30 to 60 degrees, commonly around 45 degrees
- On a properly positioned MLO view, to what level should the pectoral muscle extend?
- Down to approximately the level of the posterior nipple line
- What does an anode target material of molybdenum provide in mammography?
- Low-energy characteristic x-rays suited to soft tissue contrast
- What is the typical kVp range used in mammography?
- Roughly 22 to 35 kVp
- Why does mammography use a low kVp technique?
- To increase subject contrast between similar soft tissue densities
- What does AEC stand for in mammography imaging?
- Automatic exposure control
- What is the purpose of the grid in mammography imaging?
- To reduce scatter radiation and improve image contrast
- What is a spot compression view used for?
- To reduce tissue thickness over a specific area for better visualization of a finding
- What is magnification mammography primarily used to evaluate?
- Microcalcifications and fine detail
- Why is a small focal spot needed for magnification mammography?
- To maintain spatial resolution despite the increased object-to-image distance
- What is the purpose of an exaggerated craniocaudal (XCCL) view?
- To better visualize the lateral breast tissue and axillary tail
