What is an artifact on a mammogram?
What is an artifact on a mammogram?
Radiologists and mammographic technologists should be familiar with the numerous artifacts that may create pseudolesions or mask true abnormalities. An artifact is defined as any variation in mammographic density not caused by true attenuation differences in the breast (,4).
What are suspicious findings on mammogram?
Abnormal mammogram results occur when breast imaging detects an irregular area of the breast that has the potential to be malignant. This could come in the form of small white spots called calcifications, lumps or tumors called masses, and other suspicious areas.

What are artifacts in imaging?
An image artifact is any feature which appears in an image which is not present in the original imaged object. An image artifact is sometime the result of improper operation of the imager, and other times a consequence of natural processes or properties of the human body.
What is artifact in breast ultrasound?
Volume averaging artifact is due to superimposition of adjacent structure and can make the biopsy needle appear to be within the lesion when it is only near it. Fig. 38.9. Ultrasound image of the breast shows reverberation artifact at the anterior wall of the cyst.
