How many positions are there in a mammogram?
The views are usually used for all routine screening clients. That is, unless there is a contraindication, screening mammograms consist of these 4 views. Not all 4 views are always performed in all mammogram studies.
What is a Mediolateral view of the breast?
The ‘medio-lateral view’, (ML) is a view from the center of the chest outward, whilst the ‘latero-medial’ view (or LM) is a view from the outer side of the breast, towards the middle of the chest. Radiologists prefer the MLO view or ‘from the side-at an angle’, view to a 90 degree projection.
What are position in mammography?
The goal for mammography positioning should be to bring the breast back to it’s natural anatomical position (with the nipple perpendicular to the chest wall) on both screening views to maximize visualization of breast tissue and to avoid superimposition of structures.
What is Mediolateral projection?
The mediolateral oblique (MLO) view is one of the two standard mammographic views, alongside the craniocaudal (CC) view. It is the most important projection as it allows depiction of most breast tissue.
Why do they cover your nipples during a mammogram?
Markers are placed over a nipple, mole, scar, area of concern or other features that could be confused with a lesion. When performing screening mammograms, skin markers can save time, improve accuracy, enhance communication and provide a better experience for the patient.
What are the 2 typical views used in mammography?
There are two standard views of the breast taken during mammography. Craniocaudal, or “CC view” (taken from top-down, shown on left), and mediolateral oblique, or “MLO view” (taken from the side at an angle, shown on right).
What is Mediolateral oblique view?
A standard mammographic view taken from an oblique or angled view, which is the most important projection as it allows imaging of the greatest amount of breast tissue and is preferred over the lateral 90º projection.
What is IMF in mammography?
IMF is the inferior border of the breast and the crease between the breast and abdominal tissue. On the MLO, it is important to include some abdominal tissue to visualize the IMF in the open position.
What is C View in mammography?
With C-View software, a 2-D image is generated using the tomosynthesis data acquired during the mammography exam, eliminating the need for additional 2-D exposures. As a result, the radiation dose is lowered to one similar to conventional mammography alone, and the exam’s compression time is reduced.
What is a BB marker?
Techno-Aide BB Skin Markers No Burn Out. In general imaging these markers are used to mark prominent nipples for identification of nipple shadows on chest x-rays. In mammography, these markers are used to identify masses, or prominent nipples.
