Microcalcifications in breast imaging are tiny white specks of calcium salts. Microcalcifications in clusters, seen on a mammogram, can be the only sign of ductal carcinoma in situ or early invasive cancer, or they can be associated with benign breast changes.

Same as micrometer (µm), one millionth of a meter.

See Meter.

(mA): 10^-3 ampere. In radiography, the current flow from the cathode to the anode in the x-ray tube is measured in milliampere. This current regulates the radiation intensity emitted by the x-ray tube.

See X-Ray Tube.

(mA min) The product of the x-ray tube operating current and the exposure time in minutes.

See Milliampere and X-Ray Tube.

(mA s) The product of the x-ray tube operating current and the exposure time in minutes.
