CAMRT Radiography Practice Exam

What is the primary imaging technique used in diagnosing breast masses?

1. Ultrasound

2. X-ray

3. Mammography

4. CT scan

The correct answer is: Mammography

Mammography is the primary imaging technique used in diagnosing breast masses because it is specifically designed for breast tissue evaluation. This X-ray examination utilizes low-dose radiation to create detailed images of the breast, allowing for the detection of abnormalities that might indicate the presence of breast cancer or other potential issues. Mammography can identify microcalcifications and masses that may not be palpable during a physical examination, which is critical in early detection and diagnosis. Its effectiveness in screening asymptomatic women has made it a standard practice in breast cancer screening guidelines. Other imaging modalities like ultrasound and MRI can aid in further evaluation or to characterize a mass after mammography has indicated a suspicious area. However, mammography remains the first-line screening tool due to its proven ability to detect breast pathology effectively. CT scans are less commonly used for breast imaging since they expose the patient to higher doses of radiation and are not the optimal choice for breast examination.
