What is MLO view in mammography?

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 2 typical views used in mammography?

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 is CC and MLO views mammography?

Standard views are bilateral craniocaudal (CC) and mediolateral oblique (MLO) views, which comprise routine screening mammography. The views are usually used for all routine screening clients. That is, unless there is a contraindication, screening mammograms consist of these 4 views.

Why do I need a spot compression mammogram?

Spot compression views show the borders of an abnormality or questionable area better than the standard mammography views. Some areas that look unusual on the standard mammography images are often shown to be normal tissue on the spot views.

How do you do MLO view?

The MLO view is taken with the X-ray beam directed from superomedial to inferolateral, usually at an angle of 30–60°, with compression applied obliquely across the chest wall, perpendicular to the long axis of the pectoralis major muscle.

What is a tangential view?

Tangential views are useful to differentiate intracutaneous radiopaque particles in a tattoo from intraparenchymal microcalcifications. Mammographic findings close to the skin such as masses, microcalcifications, skin dimpling or shaded areas always pose a problem of differential diagnosis.

Why do we perform MLO view in mammography?

What is the CC view?

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 the external lateral portion of the breast as much as possible.

What is MLO spot compression?

A spot view (also known as a spot compression view or focal compression view) is an additional mammographic view performed by applying the compression to a smaller area of tissue using a small compression paddle, increasing the effective pressure on that spot.

Is developing asymmetry bad?

Developing asymmetry is an important and challenging mammographic finding, associated with a moderate risk of malignancy. Biopsy is nearly always indicated if the finding persists following diagnostic evaluation.

What’s the difference between MLO and CC mammography?

Mammography views. The ML view loses significant tissue volume in the upper outer quadrant of the breast where statistically the most breast cancers are found. By doing an MLO view you get extra tissue without extra exposure. The downside of the MLO view is it is not 90 degrees to the cc view so localisation of a lesion requires some thought.

How are cc and xccl images used in mammography?

The most frequent additional imaging needed is an exaggerated laterally CC view (also known as XCCL) so that there is visualization of fat behind the lateral portion of the fibroglandular tissues (Fig. 3.4a, b ). ( a, b) Example of standard craniocaudal (CC) view and exaggerated craniocaudal view laterally (XCCL) images, respectively.

How is clinical correlation used in diagnostic mammography?

•To view diagnostic mammography as a tailored examination •To select appropriate diagnostic views –By the radiologist –By the technologist Clinical Correlation •Information from the patient •Information from the doctor •Information from the technologist •Appropriately mark the area •Ensure inclusion of the clinical area on the images

Which is the standard view in a mammogram?

Standard views are bilateral craniocaudal (CC) and mediolateral oblique (MLO) views, which comprise routine screening mammography. 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.
