Medical Imaging Technology, 3D Printing, and Medical Applications

Abstract

3-dimensional (3D) printing denotes the various approaches that aid the manufacture of 3D anatomical structures from the patient data that is acquired. These models are rapidly gaining popularity in the medical community. Medical imaging modalities such as Magnetic resonance imaging (MRI), Computed Tomography (CT), and even ultrasonography have been used to manufacture the 3D models. Currently, 3D printing has various medical applications, which include pre-surgical planning, intra-operative planning, simulation models, manufacture of prostheses and surgical tools. The PubMed database was searched for articles on 3D printing and applications of 3D printing. Relevant articles with basic physics, applications, advantages, and limitations were included in the study. The studies considered were dated from 2012 to 2024. 3D printing is rapidly achieving prominence in the medical field due to its numerous applications. 3D printed equipment has various advantages, such as better fit due to customized implants, and better patient comfort, with lesser manufacturing cost. Simulation models, Preoperative and intra-operative models help in guiding the surgeons during the surgery as well as deciding appropriate approaches for a better surgical outcome and success.
