An evaluation of parameters compliance obtained through quality control tests in mammography undertaken at Sao Paulo, Brazil, from 2000 to 2009

The Portaria 453 of 1998 established a mandatory police for quality assurance program in Radiodiagnostic (PGQ), as a constituent part the Quality Control of Equipment, which includes a minimum set of constancy tests, it establishes acceptance performance limits and requires a minimum frequency to be undertaken. The Resolution 64 of 2003 added a methodology to undertake tests in Mammography which was substituted by Resolution 1016 of 2006 up today. The objective of mammography is the early detection of breast anomalies in order to indicate the efficient treatment with better chance of healing. The PGQ goal is optimization of the detection process with a good quality image and a minimum necessary patient dose. This work presents an evaluation of improvement in adequacy of main parameters obtained through quality assurance tests in Mammography undertaken at Sao Paulo from 2000 to 2009. (author)
