Her team worked with Vladimir Kushnir and Vladimir Lamm at the School of Medicine, Zhu's team of PhD students, including Tiger Nie, started a trial in patients in July 2022. Zhu also is a professor of radiology at the School of Medicine. The combined system allowed them to detect and classify cancerous tissue samples with a 93% diagnostic accuracy. At present, level 1 evidence of the technology’s clinical applications doesn’t exist. This is a nascent technology with a potential wide applicability for retinal vascular disease. Shuying Li, a biomedical engineering PhD student, used the imaging data to train a machine learning algorithm to differentiate between "normal" and "cancerous" tissue. Optical coherence tomography angiography (OCTA) is a new, non-invasive imaging technique that generates volumetric angiography images in a matter of seconds. The technique provided more information about an abnormality than surface-level, white-light images currently used by physicians. Hongbo Luo, a PhD student in Zhu's lab, led the work. By collaborating with physicians at Washington University School of Medicine and with Chao Zhou, associate professor of biomedical engineering, the team developed a small OCT catheter, which uses a longer wavelength of light, to penetrate 1-2 mm into the tissue samples. This technique, however, does not detect and diagnose subsurface lesions.Īn endoscopy OCT essentially shines a light in the colon to help a clinician see deeper to visualize and diagnose abnormalities. OCT has been shown to be a useful diagnostic tool in diagnosing early stage. The clinician can obtain real-time images of the architecture of the skin without pretreatment or gels. Screening for colon cancer now relies on human visual inspection of tissue during a colonoscopy procedure. Optical coherence tomography (OCT) is a non- invasive optical imaging technique that uses low-power infrared laser light to image up to 2 mm beneath the skin surface. Final results of the PATHFINDER study by GRAIL on multi-cancer early detection tests announced.Research could lead to a new therapeutic option for patients with bladder cancer.Physical activity may help improve outcomes for colon cancer patients after surgery.
