Medical imaging has been playing a vital role in revolutionizing the healthcare landscape by offering invaluable insights into the human body for diagnosis, treatment, and early detection of health risks. From the optical microscope, which enabled the discovery of cells and changed modern medicine forever, to the invention of X-rays to its early use on battlefield in World War I to post-World War II technological innovations like ultrasound, CT, MRI to recent adoptions of PET-CT, medical imaging has undergone a remarkable transformation.

In recent years, computing and technological advancements have helped medical imaging move forward by leaps and bounds. And with the ongoing explosion of Artificial Intelligence and resulting applications, we are beginning to see another wave of innovation and transformation in the field of medical imaging. While these technologies and trends enable faster and more accurate diagnoses, facilitate personalized treatments, and improve patient outcomes, they also bring a set of challenges that have implications for all stakeholders within the healthcare ecosystem.
Data-driven medical imaging
Data-driven medical imaging is a recent approach that can support large image data set to guide and support with interpretation and review of medical images. From operational perspective, data-driven insights and advanced analytics can further optimize imaging workflows, improve resource allocation, and contribute to making the process more accessible, cost-effective, and sustainable. additionally, it can provide an enhanced patient engagement. In conjunction with AI and other emerging technologies, scientists can process vast datasets or even create realistic synthetic datasets to accelerate research and innovation.

Artificial intelligence and machine learning in medical imaging
One of the most promising and impactful trends in medical imaging is the application of AI and machine learning (ML) to analyze medical images and data. AI and ML models can be trained to learn from data and perform tasks that may otherwise require human intelligence in the form of recognition, classification, segmentation, and prediction of patterns or traits.

AI and ML can enhance medical imaging by detecting anomalies, measuring outcomes, and providing decision support for clinicians by improving the overall accuracy and efficiency of diagnosis. It can also help enhance the quality and resolution of images by using advanced image processing and reconstruction techniques, such as deep learning and generative adversarial networks (GANs).
