基于MRI的3D打印技术：临床应用中的优势与前景.

BACKGROUND: 3D printing facilitates the creation of accurate physical models of patient-specific anatomy from medical imaging data sets. Until now, most models have been created from Computed Tomography (CT) data, but more and more people are interested in creating models from other data sets, such as ultrasound and magnetic resonance imaging. In particular, magnetic resonance imaging has great potential in 3D printing due to its good tissue characteristics and lack of ionizing radiation. OBJECTIVE: To systemically introduce the basic concept and process of 3D printing, to discuss the application of magnetic resonance imaging-based 3D printing technology in the clinical applications and bedside teaching in the fields of cardiovascular system, nervous system, osteoarticular system, oral and maxillofacial and genitourinary systems, and to briefly describe the research progress of the bio-3D printing technology. METHODS: We searched WanFang, CNKI, VIP, PubMed and web of science databases for relevant articles published from 2010 until now. The keywords were “3D printing, 3D printed, Additive Manufacturing, Rapid Prototyping, MRI, Magnetic Resonance Imaging” in Chinese and English, respectively. Fifty publications were in included in the final analysis. RESULTS AND CONCLUSION: 3D printing can be widely used in many fields of medicine. Magnetic resonance imaging plays an important role in 3D printing modeling due to its multi-planar reconstruction, multi-parameter MRI, multi-sequence imaging and high soft tissue resolution. It can not only print personalized models before operation, but also print personalized prostheses and implants. In addition, with the gradual development of bio-3D printing, more and more people begin to focus on this new field. [ABSTRACT FROM AUTHOR]
