T1 MRI of the same lipoma: High intensity signal mass with regions of ill-defined margins [23] Ultrasonography of a liposarcoma for comparison: In this case a heterogeneous mass consisting of an upper hyperechoic portion, corresponding to lipomatous matrix, and areas of hypoechogenicity corresponding to nonlipomatous components.
Automated whole-breast ultrasound (AWBU) is a technique that produces volumetric images of the breast and is largely independent of operator skill. It utilizes high-frequency ultrasound to help perform a diagnostic evaluation of the lactiferous ducts (duct sonography) [5] and make dilated ducts and intraductal masses visible.
Breast ultrasounds may be used with or without a mammogram. Breast ultrasound is the use of medical ultrasonography to perform imaging of the breast. It can be used as either a diagnostic or a screening procedure. [38] It may be used either with or without a mammogram. [39]
A breast mass, also known as a breast lump, is a localized swelling that feels different from the surrounding tissue. [1] Breast pain, nipple discharge, or skin changes may be present. [1] Concerning findings include masses that are hard, do not move easily, are of an irregular shape, or are firmly attached to surrounding tissue. [2]
An ultrasound can detect abnormalities in the breast tissue by using high-frequency sound waves that bounce off the tissue that then transform into images that can be interpreted. It has been shown to be more useful in searching for masses in dense breast tissue. [16] Ultrasounds have a sensitivity of 76% and specificity of 84%. [17]
to identify adnexal masses, including ectopic pregnancy, to diagnose gynecologic cancer; in infertility treatments to track the response of ovarian follicles to fertility medication (i.e. Pergonal). However, it often underestimates the true ovarian volume. [2] Through transvaginal sonography ovarian cysts can be aspirated.
In most cases breast cancers are asymptomatic and are detected by routine clinical screening exams. In about 30% of cases a breast mass may be felt. [13] [14] The mass will not fluctuate with the menstrual period. [15] Changes to the overlying skin including dimpling, pinching, orange peel-like texture, or nipple retraction may be seen. [16]
ICCB tumors are small (i.e. 58%-75.4% less than 2-5 centimeters and 22%-38% more than 2-5 centimeters in largest diameters), asymptomatic masses first detected by palpation or screening methods such as mammography or medical ultrasound.
