Microcalcification on mammography: approaches to interpretation and biopsy

A Bayesian Network to Assist Mammography Interpretation

Correspondence: Reply to ‘Quantitative evaluation of X-ray dark-field images for microcalcification analysis in mammography'

Scherer et al.1 claim that the phantom study in our Article2 might not reliably model real microcalcifications in human breast and referred to previous publications3–5 to emphasize that the scattering signal depends on particle grain sizes. Specifically, they mention Michel et al.’s simulation results6, which report a larger scattering signal of calcium hydroxyapatite compared with calcium oxal...

Approach to the Interpretation of Muscle Biopsy

The history of muscle biopsy dates back to 1860 when Duchenne first performed a biopsy on a patient with symptoms of myopathy. Introduction of enzyme histochemical methods by Victor Dubowitz in 1970 revolutionised the role of muscle biopsy in the diagnosis of various primary and secondary muscle diseases.1 Diagnosis of various subtypes of dystrophies was further made easy with beginning of immu...

An approach to endomyocardial biopsy interpretation.

The endomyocardial biopsy (EMB) remains the gold standard mode of investigation for diagnosing many primary and secondary cardiac conditions. Through a percutaneous and transvenous route, tissue fragments are generally procured from the right ventricular septum, with very few complications. Widespread use of EMB followed the development of heart transplantation as a means to follow allograft re...

Comparing the Performance of Image Enhancement Methods to Detect Microcalcification Clusters in Digital Mammography

BACKGROUND Mammography is the primary imaging technique for detection and diagnosis of breast cancer; however, the contrast of a mammogram image is often poor, especially for dense and glandular tissues. In these cases the radiologist may miss some diagnostically important microcalcifications. In order to improve diagnosis of cancer correctly, image enhancement technology is often used to enhan...
