Artifacts may influence the diagnostic quality of the images. In radiotherapy treatment planning, the reduction of CT artifacts is also very important. Metal implants cause severe artifacts on MRI, especially in signal-loss, signal-pileup, geometric distortion, and failure of fat-suppression. The composition of prosthetic implants is decisive in determing the quality of MR imaging. [ABSTRACT FROM AUTHOR]

Artifacts can affect the diagnostic quality of the images. Artifacts must also be reduced in radiotherapy for precise treatment planning. Metallic implants can cause considerable artifacts in magnetic resonance imaging, in particular signal loss, signal pile-up, geometric distortions and fat suppression failure. The composition of the prosthesis material determines the extent of the artifacts and the quality of the MR images. CT also has to contend with metal artifacts. Image quality issues are also possible with ultrasound. [ABSTRACT FROM AUTHOR]
