on mammogram-its value in the diagnosis of breast cancer.
A CBR driven genetic algorithm for microcalcification
The histological profile of this study indicates that rats exposed to Pb presents a minimal tubular necrosis and tubular microcalcification
, perhaps it is the beginning of nephrolithiasis, which is a disease characterized by the presence of stones in the excretory channel of kidneys.
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.
Other topics include an active contour model for selective segmentation, attributed graph visualization of collaborative workspaces, detecting microcalcification
clusters in digital mammograms, perspective correct normal vectors for Phong shading, and ship hull fitting using NURBS.
The women ( who had all been sent for tests because they had suspected breast cancer ( have been called back for further tests because of a case in France when an Agfa scanner failed to pick up a condition called microcalcification
A case in France suggested the equipment may make it difficult to detect microcalcification
- usually harmless but in very few cases an early sign of breast cancer.
The machinery was withdrawn after a single case in France suggested that, in some patients, it might make a certain abnormality, microcalcification
, difficult to detect.
In the late 1970s, investigators began developing methods to characterize microcalcification
clusters by computer as having a benign or malignant appearance.
Mammogram showed mass lesion with clustered microcalcification
with ill-defined margin.
