What is MLO view on a mammogram?
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.
What are the basic views of mammography?
Screening mammography refers to an examination of an asymptomatic woman to detect clinically occult breast cancer. The screening examination includes two views of the breast, sometimes referred to as the “standard views”: a mediolateral oblique and a craniocaudal view (Figure 36f-1).
What are the 2 views of mammogram?
There are two standard mammographic projections: a mediolateral oblique (MLO) view and a craniocaudal (CC) view. Correct positioning is crucial to avoid missing lesions situated at the margins of the breast.
What is tangential projection?
The tangential projection represents an extraoral projection which with success can be performed with the dental X-ray set. The film is placed lateral to the angle of the mouth in a vertical position level with either the maxilla or the mandible.
What does a cancerous lump look like on a mammogram?
What does breast cancer look like on a mammogram? Any area that does not look like normal tissue is a possible cause for concern. The radiologist will look for areas of white, high-density tissue and note its size, shape, and edges. A lump or tumor will show up as a focused white area on a mammogram.
What is a 1 View asymmetry?
An asymmetry lacking convex margins that is seen on only one view may be a real lesion that either is obscured by surrounding breast tissue on the orthogonal view or is not included in the orthogonal view.
What does a Craniocaudal view mean?
The craniocaudal view (CC view), along with the MLO view, is one of the two standard projections in a screening mammography. It must show the medial part as well as the external lateral portion of the breast as much as possible.
What is the lateromedial view (LM view)?
The lateromedial view (or LM view) is a supplementary mammographic view where the bucky is placed up against the sternum and the and film is taken in a true lateral projection.
What is the lateromedial view of breast?
The lateromedial view (or LM view) is a supplementary mammographic view where the bucky is placed up against the sternum and the and film is taken in a true lateral projection. This view allows the medial breast to be closest to the film.
What is the lateral projection of the humerus?
Perpendicular to the midportion of the humerus and the center of the IR. The lateral projection demonstrate the entire length of the humerus. A lateral image is confirmed by superimposed epicondyles. Beam divergence possibly partially closing the elbow joint. No great variation in radiographic densities of the proximal and distal humerus.
How do you position an image receptor for lateral projection?
The body position, whether oblique or facing toward or away from the image receptor, is not critical as long as a true projection of the lateral arm is obtained. Place the top margin of the image receptor approximately 1.5 inches above the level of the head of the humerus.
