Cellphone enabled point-of-care assessment of breast tumor cytology and molecular HER2 expression from fine-needle aspirates
NPJ BREAST CANCER, 7(1).
TL;DR:
It was found that FNA cytology specimens imaged by the EpiView-D4 were adequate for assessment of lesional cellularity and tumor content, and the device could reliably distinguish between HER2 expression levels across multiple different cell lines and animal xenografts.
