ACMIT and its partners have published a new paper in the International Journal of Bioprinting entitled “Evaluation of 3D-printed silicone phantoms with controllable MRI signal properties“.
3D printing technology is widely used for creating magnetic resonance imaging (MRI) phantoms, mimicking tissue, and contrast levels found in real patients. Traditionally, 3D-printed structures were filled with gels containing contrast agents. Recently, studies have shown that some 3D-printed materials can be directly used to create MRI phantoms. This study aimed to investigate MRI signal properties of 3D-printed phantoms made of silicone in MRI. The results demonstrated good stability of the T1 and T2 values over time and also good agreement for the replicas compared to the original samples, confirming the reproducibility of the printed materials. A good agreement was observed between the MRI signal property in tumor phantoms and the reference values of invasive ductal carcinoma of the breast in patients.
