New Device to Diagnose Ovarian Cancer

A novel imaging device has been developed by scientists to diagnose early-stage ovarian cancer in high-risk women. The new technique may be better than the current standard procedure of preemptively removing the ovaries.

Ovarian cancer has a low survival rate because a lack of reliable screening techniques usually means the disease remains hidden until the later stages. Now researchers have drawn on the unique advantages of multiple imaging tools to test a new way of spotting early-on the tissue irregularities that signal cancer.

For their diagnostic device, the researchers combined the contrast provided by photoacoustic imaging, the high-resolution subsurface imaging provided by optical coherence tomography, and the deeper tissue imaging provided by pulse-echo ultrasound. They tested their device, described by the team in the September issue of the Optical Society's (OSA) open-access journal Biomedical Optics Express, by imaging both pig and human ovarian tissue, and correctly identified malignant tumors that were later confirmed by staining the tissue and examining it under a microscope. These initial tests were performed on tissue that had been surgically removed, but the diameter of the device - at only 5 mm - is small enough that it could potentially be inserted through a small slit to image tissue in live patients.
