Breast imaging is a subspecialty of radiology dedicated to diagnosing diseases of the breast. It involves a range of imaging procedures such as mammography, ultrasound, and magnetic resonance imaging (MRI).
Overview[edit]
Breast imaging is an essential tool in the early detection and diagnosis of breast cancer, the most common cancer among women. It can also be used to evaluate the extent of the disease, guide biopsy procedures, and monitor the effectiveness of treatment.
Types of Breast Imaging[edit]
Mammography[edit]
Mammography is the most common type of breast imaging. It uses low-dose x-rays to create images of the breast. There are two types of mammography: screening mammography and diagnostic mammography.
Screening Mammography[edit]
Screening mammography is used to detect breast changes in women who have no signs or symptoms of breast disease. It usually involves two x-ray images of each breast.
Diagnostic Mammography[edit]
Diagnostic mammography is used to investigate suspicious breast changes such as a new breast lump, breast pain, an unusual skin appearance, nipple thickening, or nipple discharge. It's also used to evaluate abnormalities detected on screening mammography.
Ultrasound[edit]
Ultrasound uses sound waves to produce images of the breast. It's often used to evaluate breast problems that are found during a mammogram or physical exam.
Magnetic Resonance Imaging (MRI)[edit]
Magnetic resonance imaging (MRI) uses a powerful magnetic field, radio waves and a computer to produce detailed pictures of the inside of the breast. It's mainly used as a supplemental tool to mammography for women who have a high risk of breast cancer.
Risks and Benefits[edit]
While breast imaging has many benefits, it also has some risks. The benefits include early detection and treatment of breast cancer. The risks include false-positive results, overdiagnosis, and exposure to radiation.
