85learned to read these nuanced differences and virtually enhance the contrast of regular MRI images without using gadolinium.%u201d Prof. Cai%u2019s Virtual Contrast-enhanced MRI without gadolinium costs significantly less than using gadolinium-based MRI contrast agents, yet has an accuracy rate of 89%, which is comparable to gadolinium-enhanced images. To ensure that this new technology benefits those who need it, Prof. Cai%u2019s research team members co-founded MedVision Limited, a PolyU start-up nurtured in the PolyVentures ecosystem that aims to revolutionise cancer diagnosis and treatment, offering a safer and cost-effective alternative to contrast agents and empowering healthcare professionals to provide the best care possible. Precision radiotherapy can also be administered in the form of brachytherapy. This technique involves implanting radioactive seeds in or near the cancer, and is commonly used to treat prostate cancer. However, the current clinical standard is to scan the prostate and its surrounding tissues with ultrasound, which can produce images that are blurry and unclear. This makes it hard to accurately identify the anatomical structure of the prostate. To address this, Prof. Cai uses AI to read ultrasound images for image segmentation %u2013 a technique to divide images into regions based on predefined categories. This approach has an accuracy rate of over 95%, saving time and relying less on the subjective judgement of radiologists. Using AI-powered segmentation for prostate cancer brachytherapy, radioactive seeds can be implanted more precisely in specific positions.HITTING THE BULLSEYE
