Virtual Reality has been changing medical diagnostics with its highly immersive 3D environments, allowing for the improvement and understanding of interaction with complex anatomical structures and an entire spate of medical conditions. The paper aims to find out how VR applies to the concept of preoperative planning for proper surgery and patient education, also looks at the role of VR in diagnostic training, dealing with the provision of a near-real environment for the development of skills. Diagnostic acuity is enhanced, leading to earlier disease detection by offering minute details for visual analysis. The facilitates timely adjustments to treatment strategies. The paper further addresses issues on ethics regarding data privacy and responsible usage of VR technology. Therefore, the work shows in a fundamental way how VR applications are changing diagnostic practices and presenting new challenges in medical fields.
