Breast cancer imaging comparisons

340 11 months ago
Magnetic resonance imaging MRI of the breast was first performed in the late s. At first, differentiation between benign and malignant breast lesions was primarily based on their differences in T1 and T2 relaxations times Rausch et al. Due to the large overlap in T1 and T2 relaxation times in benign and malignant breast lesions, it became apparent that contrast administration was mandatory for reliable breast MRI. Heywang et al. The reported sensitivity and specificity may vary in different publications due to differences in study populations, and technical and diagnostic criteria used. These numbers are superior to mammography and ultrasound, and are independent of factors such as tumor histology, breast density, and hormonal therapy use.

Box Photoacoustic optoacoustic imaging can visualize vasculature deep in tissue using the high contrast of hemoglobin to light, with the high-resolution possible with ultrasound detection. Since angiogenesis, one of the hallmarks of cancer, leads to increased vascularity, photoacoustics holds promise in imaging breast cancer as shown in proof-of-principle studies. Here for the first time, we investigate if there are specific photoacoustic appearances of breast malignancies which can be related to the tumor vascularity, using an upgraded research imaging system, the Twente Photoacoustic Mammoscope. In addition to comparisons with x-ray and ultrasound images, in subsets of cases the photoacoustic images were compared with MR images, and with vascular staining in histopathology.
