Abstract

Electrical Impedance Tomography (EIT) is a non-invasive procedure using electrical impedance to image the human breast. Due to its mobility and using non-compression technique it is appealing to patients. This scanning device does not emit any ionizing radiation thus it can be done on pregnant women by means of no age limit. Since the EIT has play some supplementary function in the breast imaging, a lot of research on its clinical accuracy has been done. Therefore, the aim is to carry out a review of EIT clinical accuracy and assess the quality of journal by using Quality Assessment of Diagnostic Accuracy Studies (QUADAS) criteria. The journals that assess the sensitivity were search through various databases and the clinical accuracy of EIT in each journal is recorded. The review shows that the range sensitivity (Sn) of EIT system to human breast in ten journals was between 17% and 94.6%. The range of specificity (Sp) is between 49% and 97.1%. The negative (NPV) and positive predictive value (PPV) is between 74% and 98%; 4% and 73.3% respectively. The accuracy (ACC) of EIT is between 69% and 80.5%. This value is found to be supported that EIT can be used as an adjunct screening technique for human breast.
