We have been asked a couple times whether or not K-Wire is MRI compatible. We cannot speak for all K-Wires since K-Wires can come in different shapes and sizes. The most common K-Wire is made of Stainless Steel. Nitinol is the second most common, we typically see it in about 8% of the K-Wires we make.
It is possible for K-Wires to be MRI compatible. Often times the distributor or OEM you purchased from will have labeling which describes the compatibility of the K-Wire you are using. If you are unsure, make sure to contact the K-Wire OEM for additional information.
