What is the ultrasonography of the breast?

Breast ultrasonography is a imaging technique used to assess abnormalities of breast tissue. This technology uses sound waves to evaluate basic structures and is useful because it is simple and does not expose women radiation. However, the use of this imaging study has a limitation because it has a relatively poor ability to pick up small details - a feature known as a solution - compared to mammography. Application of breast ultrasonography includes evaluation of masses detected during manual examination and localization of breast masses during biopsy. A converter is used for the emit of these sound waves, and the time to be recorded by the emitted wave is recorded. From this information, the ultrasonic machine is able to reconstruct the two -dimensional image of the basic structures.

The use of ultrasonography of the breast has a number of different advantages. Unlike radiographic techniques such as computer tomography scanning (CT), this imaging modality does not use dangerous ionizing radiation that could damage the subcantDue tissue with repeated exposure. Breast ultrasonography is also easy, usually does not cause any pain or discomfort to the patient and is relatively low costs.

Unfortunately, there are also some disadvantages for the use of breast ultrasonography. The images obtained from the procedure are often as good as the technologist who has conducted a study. The results of the procedure may also be distorted by excessive subcutaneous fat levels. Ultrasound can identify large weights, but usually does not have sufficient resolution for mass detection that has a diameter of less than 0.5 inches (1.27 cm).

The most common use of ultrasonography of the breast is the evaluation of the LAG on the found in the tissue of the breast. It is excellent for fixed material distinguishes that could indicate a tumor, from cystic materials that are filled with liquid and often benign. Ultrasound are often used to help physicians in performing breast mass biopsy because the doctor is able to leadReal time needle on the basis of its access to matter. Breast ultrasound is also useful in identifying lymph nodes surrounding breasts that are important because malignant tumors often spread to these lymph nodes, causing it to increase.

Routine ultrasonography of breast is usually not used as a method for screening for breast cancer, because mammography has a more sophisticated ability to detect small matter. However, it plays a role in evaluating masses detected in manual breast examination, especially in women under 40 years of age. In the younger population, mammography has reduced resolution, because the breast tissue of these women is too dense. As a result, ultrasonographic provides more information in these younger patients.
