Digital zoom of the full field digital mammogram versus magnification mammography: a systematic review.

Project summary

Objectives

To compare the technical and diagnostic performance of digital zoom of Full-Field Digital Mammography (FFDM) and digital magnification mammograms to visualize, classify and diagnose microcalcifications.

 

 

Method

An extended search in MEDLINE, EMBASE, CINAHL, Engineering Village and Web of Science were performed. To find existing reviews, the Cochrane Library was searched. International and national guidelines, conference presentations, reference lists in included studies and citations and grey literature databases were searched for ongoing and unpublished studies.

Studies of mammograms from non-symptomatic women recalled from screening for diagnostic mammography where digital zoom, geometric magnification mammogram or both are used or compared for diagnosis of microcalcifications are included.  Monte Carlo Studies and Phantom studies of digital zoom, magnification mammogram or both for visualisation of microcalcifiacitons were also included.

Two authors independently reviewed abstracts and full-text publications against the inclusion criteria, and appraised the included studies for risk of bias and applicability.  The same Authors performed the Data extraction in cooperation. Pooled sensitivity, specificity and summary ROC curves will be calculated for the diagnostic test studies.
