Abstract
Breast cancer is the most common malignancy in women. Most effective method for treatment is early removal of cancer tissue. Widely used modalities in detection of breast cancer are mammography, magnetic resonance imaging (MRI), and ultrasonography. An alternative technique, which is in clinical trials phase, is microwave breast tomography (MMT). MMT is specific for cancer tissues. It relays on high contrast of dielectric coefficient between healthy and cancer tissue. This study aims to compare MRI and MMT with histopathology (HP) reports. Methods To evaluate the MMT in clinical settings, pre-operative MMT measurements are obtained from patients who has planned surgery and have a breast MRI, after informed consent was obtained. By using MMT outcomes, images were drawn using jet color mapping. A group of doctors blind to MRI and HP results were evaluated MMT images. MMT and MRI measurements of each patient is compared with HP reports of specimen. Results: When dimensions of lesions detected in MMT compared with MRI and HP reports, MMT dimensions were more congruent with HP results. Median (minimum-maximum) lesion dimensions of MMT, HP, and MRI respectively are: 28.05 (11 – 35.7), 24 (10 - 35), and 25 (8 - 44). Median MMT/HP and MRI/HP ratios are 103% and 91%. Conclusion: MMT results are more congruent with HP results than MRI, but larger series are required for further analysis.
