Breast Ultrasound[edit]

Breast ultrasound is a diagnostic imaging technique used to evaluate the breast tissue. It utilizes ultrasound waves to produce images of the internal structures of the breast, aiding in the detection and characterization of breast cancer and other breast abnormalities.

Overview[edit]

Breast ultrasound is a non-invasive procedure that uses high-frequency sound waves to create images of the breast tissue. It is often used as a complementary tool to mammography, especially in women with dense breast tissue where mammograms may not be as effective.

Indications[edit]

Breast ultrasound is indicated in several scenarios, including:

Evaluation of a palpable breast lump.
Further assessment of abnormalities detected on a mammogram.
Guidance for biopsy procedures.
Monitoring of known benign breast conditions.
Assessment of breast implants.

Procedure[edit]

During a breast ultrasound, a radiologist or a trained sonographer applies a gel to the skin of the breast and uses a handheld device called a transducer. The transducer emits sound waves that penetrate the breast tissue and reflect back to create an image on a monitor.

Advantages[edit]

Breast ultrasound offers several advantages:

It is a painless and non-invasive procedure.
It does not use ionizing radiation, making it safe for repeated use.
It provides real-time imaging, which is useful for guiding biopsies.
It is effective in distinguishing between solid masses and fluid-filled cysts.

Limitations[edit]

Despite its benefits, breast ultrasound has limitations:

It may not detect all types of breast cancer, particularly small calcifications.
It is operator-dependent, requiring skill and experience for accurate interpretation.
It may result in false positives, leading to unnecessary biopsies.

-'''Breast ultrasound''' is a non-invasive diagnostic imaging technique used to visualize the internal structures of the [[breast]]. It employs high-frequency sound waves to produce detailed images of the breast tissue, aiding in the detection and characterization of breast abnormalities, including [[cysts]], [[fibroadenomas]], and [[breast cancer|cancerous tumors]]. Unlike [[mammography]], which uses X-rays, breast ultrasound does not involve exposure to ionizing radiation, making it a safer option for certain populations, such as pregnant women and those with dense breast tissue.

-==Indications==
+[[File:Mamma_ca_1.jpg|thumb|right|Breast ultrasound image showing a suspicious mass.]]
-Breast ultrasound is commonly used for several purposes:
-* To further evaluate abnormalities detected by mammography or during a physical examination.
-* To distinguish between solid tumors and fluid-filled cysts.
-* To guide [[biopsy|biopsies]] of suspicious breast lesions.
-* As a supplementary screening tool for women with dense breast tissue, where mammography may be less effective.
-* In pregnant or lactating women, where other forms of breast imaging may pose risks.
-==Procedure==
+'''Breast ultrasound''' is a diagnostic imaging technique used to evaluate the [[breast]] tissue. It utilizes [[ultrasound]] waves to produce images of the internal structures of the breast, aiding in the detection and characterization of [[breast cancer]] and other breast abnormalities.
-During a breast ultrasound, the patient lies on their back or slightly turned on an examination table. A small amount of water-based gel is applied to the area of interest to facilitate the transmission of sound waves. A handheld device called a transducer is then moved over the skin surface of the breast. The transducer emits sound waves that penetrate the breast tissue and bounce back to the device, creating echoes that are converted into digital images displayed on a monitor.
-==Benefits and Limitations==
+== Overview ==
-'''Benefits:'''
-* No exposure to ionizing radiation.
-* Can effectively image dense breast tissue.
-* Non-invasive and relatively quick procedure.
-* Useful for guiding needle biopsies.
-'''Limitations:'''
+Breast ultrasound is a non-invasive procedure that uses high-frequency sound waves to create images of the breast tissue. It is often used as a complementary tool to [[mammography]], especially in women with dense breast tissue where mammograms may not be as effective.
-* May not detect some early signs of cancer, such as microcalcifications, as effectively as mammography.
-* Operator-dependent technique that can vary in accuracy.
-* Not a replacement for mammography in general breast cancer screening.
-==Interpretation==
+== Indications ==
-The images produced by breast ultrasound are interpreted by a radiologist. Findings are typically categorized according to the BI-RADS (Breast Imaging-Reporting and Data System) scale, which ranges from 0 (incomplete) to 6 (known biopsy-proven malignancy), guiding the next steps in patient management.
-==Risks==
+Breast ultrasound is indicated in several scenarios, including:
-Breast ultrasound is considered a safe procedure with minimal risks. The primary concern is the potential for false-positive or false-negative results, which could lead to unnecessary anxiety, further testing, or delayed diagnosis.
-==Conclusion==
+* Evaluation of a palpable breast lump.
-Breast ultrasound is a valuable diagnostic tool in the evaluation of breast abnormalities, particularly as a complement to mammography. Its safety profile and effectiveness in certain patient populations make it an important component of comprehensive breast care.
+* Further assessment of abnormalities detected on a mammogram.
+* Guidance for [[biopsy]] procedures.
+* Monitoring of known benign breast conditions.
+* Assessment of breast implants.
