Measurement artifact. Something that appears to exist because of the way it is measured - discontinuous measurement, poorly scheduled measurement periods, insensitive/ limiting measurement scales) (artifact - when data give a misleading picture of the behavior because of the way it is measured)

Additionally, what is a blooming artifact? Blooming artifact is a susceptibility artifact encountered on some MRI sequences in the presence of paramagnetic substances that affect the local magnetic milieux. One of the most powerful and widely available sequences which maximizes blooming artifact to great effect is susceptibility-weighted imaging (SWI).

Regarding this, what is an artifact on CT scan?

Artifacts are commonly encountered in clinical computed tomography (CT), and may obscure or simulate pathology. There are many different types of CT artifacts, including noise, beam hardening, scatter, pseudoenhancement, motion, cone beam, helical, ring, and metal artifacts.

What are motion artifacts?

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.

What are artifacts in anatomy?

In medical imaging, artifacts are misrepresentations of tissue structures produced by imaging techniques such as ultrasound, X-ray, CT scan, and magnetic resonance imaging (MRI). Physicians typically learn to recognize some of these artifacts to avoid mistaking them for actual pathology.
