Ultrasound imaging of the breast uses sound waves to produce pictures of the internal structures of the breast. It’s primarily used to help diagnose breast lumps or other abnormalities your doctor may have found during a physical exam, mammogram or breast MRI. Ultrasound is safe, noninvasive and does not use ionizing radiation.
Ultrasound equipment with a high-resolution linear transducer is necessary. Transducers with 7-MHz to 12-MHz frequency are preferred because of better near-field resolution.
Too deep a focus causes volume-averaging artifacts and gives erroneous results about tissue consistency. Matrix probes that can be focused in the short axis as well offer better resolution.
Major indications include the following:
Focal abnormality on mammography
Nipple discharge (read : Clinical breast exam in Kenya )
Follow-up of lesions not biopsied
Determination of lesion extent in patients with suspicious or malignant nodules
Assessment of regional lymph nodes in patients with suspicious or malignant lesions
Guiding interventional procedures
How is Clinical ultrasound in Kenya done
You will be asked to undress above the waist. You will be given a gown to drape around your shoulders. Remove all jewelry from around your neck.
Gel will be put on your breast so the transducer can pick up the sound waves as it is moved back and forth over the breast. A picture of the breast tissue can be seen on a TV screen.
A breast ultrasound test usually takes between 15 and 30 minutes. More time may be needed if a breast exam will be done or if a biopsy is also planned. You may be asked to wait until a radiologist has reviewed the pictures. The radiologist may want to do more ultrasound views of some areas of your breast.
