Micronodules need to be evaluated by cytology only in the event of suspicious finding at US (Solid hypoechoic with microcalcifications
) or personal history.
In addition, the diagnostic accuracy of ultrasound was high in the case of palpable masses; however, mammography is the best technique for screening and identifying patients with non-mass-like breast lesions and microcalcifications
. Ultrasound is not a perfect screening technique considering the false positive and false-negative results.
Usefulness of MRI of microcalcification
lesions to determine the indication for stereotactic mammotome biopsy.
CT Imaging of Breast Tumor Microcalcification
As for female patients, age (<45y/[greater than or equal to]45y), tumor size (P <0.001), multifocality (P = 0.05), and the presence of microcalcifications
on US (P <0.001) were significantly associated with CLNM (P <0.001) (Table 4).

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 were six nodules, the largest size 20x12 mm in diameter with microcalcification
. There was a hypoechoic solid lesion measuring 14 x 9 mm in size compatible with a parathyroid adenoma on the left side.
