CAMRT Radiography Practice Exam

What imaging technique is known for displaying the anatomical features of the breast?

1. CT scan

2. X-ray

3. Mammography

4. Ultrasound

The correct answer is: Mammography

Mammography is a specialized imaging technique specifically designed for visualizing the anatomical features of the breast. It utilizes low-energy X-rays to create detailed images of breast tissue, enabling radiologists to detect abnormalities, such as tumors or microcalcifications, at an early stage. The compression applied during this procedure helps to spread out breast tissue, improving image quality and enhancing the detection of potential issues. Other imaging modalities, such as CT scans, X-rays, and ultrasounds, while useful for various diagnostic purposes, do not have the same level of specificity or sensitivity for examining breast tissue. CT scans are typically used for a more comprehensive evaluation of internal organs but are not suitable for breast imaging due to the radiation dose and lack of detail in breast structures. X-rays are more general and do not provide the targeted assessment needed for breast tissue. Ultrasound can assist in breast imaging, particularly in guiding biopsies or assessing lumps, but it does not replace the detailed imaging provided by mammography, as it is more operator-dependent and often less effective for initial screening.
