WebMar 23, 2024 · Motion artifact is a patient-based artifact that occurs with voluntary or involuntary patient movement during image acquisition. Misregistration artifacts, which appear as blurring, streaking, or shading, are caused by patient movement during a CT scan. Blurring also occurs with patient movement during radiographic examinations. WebGas bubble motion during CT generates a semicircular air-attenuation artifact that has not been previously described to our knowledge. The artifact is typically found in bowel and other liquid-containing structures in which a bubble of gas floats up through a liquid medium during CT.
