Echogenicity (sometimes as echogenecity) or echogeneity is the ability to bounce an echo, e.g. return the signal in medical ultrasound examinations. In other words, echogenicity is higher when the surface bouncing the sound echo reflects increased sound waves.
Ultrasound has 68–98% sensitivity of detecting ILC. ILC shows irregular or angular mass with hypoechoic or heterogenous internal echoes, ill-defined or spiculated margins, and posterior acoustic shadowing. [10] Loss of E-cadherin is common in lobular carcinoma but is also seen in other breast cancers. [11]
Breast ultrasound is a medical imaging technique that uses medical ultrasonography to perform imaging of the breast. It can be performed for either diagnostic or screening purposes [ 1 ] and can be used with or without a mammogram . [ 2 ]
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.
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.
Despite their propensity to grow rapidly and deform the overlying breast tissue, approximately 20% of phyllodes tumors can present as a nonpalpable mass on screening mammography. [12] Other imaging tools used to assess the size and spread of a phyllodes tumor include ultrasound and magnetic resonance imaging (MRI). [ 11 ]
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]
Although hematometra can often be diagnosed based purely on the patient's history of amenorrhea and cyclic abdominal pain, as well as a palpable pelvic mass on examination, the diagnosis can be confirmed by ultrasound, which will show blood pooled in the uterus and an enlargement of the uterine cavity.
