Metal artifact reduction (MAR) algorithms are commonly used in computed tomography (CT) scans where metal implants are involved. However, MAR algorithms also have the potential to create new artifacts in reconstructed images. We present a case of a screw pseudofracture due to MAR on CT.
金属伪影减少(MAR)算法常用于涉及金属植入物的计算机断层扫描(CT)中。然而,MAR算法也有可能在重建图像中产生新的伪影。我们报告一例因CT上的MAR导致的螺钉假骨折病例。
