To recognize the artefacts created by wrong positioning method / iatrogenic, defective processing algorithms and malfunctioning equipment With the invention of Tomosynthesis, superimposition of breast tissues which is a major disadvantage in 2D mammograms has been overcome. This has greatly improved staging of BI-RADS classification and reduces the incidence of both false positive and false negative diagnosis. But these new equipment are still capable of creating artifacts that can sometimes mimic a finding or superimpose itself over certain breast areas and cause a disruption in...

Mammography machine used -Fuji Film Amulet Innovality 200 mA Patients referred to the Department of Radiology and Imaging Scienceswho underwent Full field digital Mammography imaging of both breasts with routine protocol were included in the study Views: CC and MLO views for both breasts Artifacts identified and studied

Most of the artefacts which were observed were due to – a) Improper positioning by the technologist which could be rectified by repositioning and making slight adjustments in the technique (n=7) b) Inadequate compression and use of wrong paddle which leads to blurring of some of the sequential images in Tomosynthesis (n=2) c) Specks of calcification seen in the axillary region of a patient due to the application of talcum powder and insufficient cleaning of the area before exposure (n=2) d) Bandage strips which was...

Most of the artifacts can be easily identified and do not interfere with the readings of the mammograms. However, there are few other artefacts that can mimic pseudo-lesions and may cause false positive findings; or in some cases conceal real abnormalities.With careful positioning techniques and adequate preparation of the patient, a considerable amount of these artefacts can be avoided
