What are the basic view of 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.
How many views are taken for a mammogram?
In a standard mammogram, you are probably familiar with the usual 4 views that will be taken: a side-to-side (MLO, we call them) and an up-down (CC) image of each breast. However, it is not unusual for additional views to be needed.
What is the 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 is digital mammography and write the basic views of mammography?
Also called full-field digital mammography is a mammography system in which the X-ray film is replaced by electronics that convert X-rays into mammographic pictures of the breast. These systems are similar to those found in digital cameras and their efficiency enables better pictures with a lower radiation dose.
What is CC in mammography?
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 a Craniocaudal view?
What is CC and MLO projections?
So, ‘Cranial-Caudal’ (CC) is a view from above. while an oblique or angled view ‘mediolateral-oblique’, or (MLO). 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.
Why Molybdenum is used in mammography?
Molybdenum is also often used as the target material for anodes used in mammography because it has an intermediate atomic number (Z=42) and the produced characteristic x-rays are of energies suited for this purpose.
What is CC and MLO views mammography?
What kind of views are used in mammography?
Standard views 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.
How is the breast positioned in a mammogram?
The breast is positioned on top of the magnification stand, decreasing the focal spot and allowing for magnification. Magnification views also involve the use of longer exposure times and higher kvp. Spot magnification views are a combination of spot compression (small paddle) and magnification (mag stand and settings) techniques.
How is the tangent view used in mammography?
The tangent view is performed for palpable abnormalities. A BB marker is placed on the skin over the area of clinical concern. The technologist then obtains an image with the BB in tangent. This helps to determine if a mammographic finding corresponds to what the patient is actually feeling.
How are spot compression views used in mammography?
For a spot compression view, the technologist uses a smaller paddle which thereby provides more focal and locally intense compression. Spot compression views are useful in the workup of focal asymmetries.
