It also fails to accurately comment on the representative nature of microcalcification
specimens in particular, for which specimen radiography is mandatory.
There was no discrete mass nor suspicious microcalcifications
or axillary adenopathy.
One of the important early symptoms of breast cancer in the mammograms is the appearance of microcalcification
clusters, which have a higher X-ray attenuation than the normal breast tissue and appear as a group of small localized granular bright spots in the mammograms.
In the majority of cases, microcalcification
turns out to be harmless but in a small number of patients, it can be an early sign of breast cancer.
Pb group: The photograph indicates a slight tubular necrosis and tubular microcalcification
(beginning of lithiasis).
Use of microcalcification
descriptors in BI-RADS 4th edition to stratify risk of malignancy.
Study findings revealed that CAD technology effectively identified 98% of the microcalcifications
, 95% of the invasive lobular carcinomas, 89% of the mixed mass/microcalcification
lesions and 84% of the masses in 273 women with confirmed breast cancer.
20,21) However, this finding has a low sensitivity (29% to 59%), since microcalcification
is often not present in malignant nodules.
The standard screening mode resolution of 50 microns is the highest screening resolution on the market, while the ultra-high resolution diagnostic mode of 25 microns demonstrates superior detail for suspicious lesion and microcalcification
A third patient was referred to Scallion with a mammogram result revealing a microcalcification
Examination of breast needle core biopsy specimens performed for screen-detected microcalcification
They include radiographically lucent oil or lipid cysts, circumscribed water density masses, areas of increased density, pleomorphic clustered microcalcification
, and suspicious spiculated masses.
