"Objects, in their tangibility," she writes, "provide a variety of stakeholders with an opportunity to debate the meaning and control of their memories." Artifacts are the touchstones that bring memories and meanings to life.
What does artifact mean in medical terms?
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.
What is an artifact on a CT scan?
Physics-based artifacts result from the physical processes involved in the acquisition of CT data. Patient-based artifacts are caused by such factors as patient movement or the presence of metallic materials in or on the patient. Scanner-based artifacts result from imperfections in scanner function.

What is an artifact in communication?
Communication Artifacts are created as expressions of human thought. They include advertisements, art, ceremonial and documentary artifacts, exchange media, and personal symbols. Advertising artifacts are objects that were created to call attention to products, services, or events.
What is ghosting in MRI?
Ghosting is a type of structured noise appearing as repeated versions of the main object (or parts thereof) in the image. They occur because of signal instability between pulse cycle repetitions. Ghosts are usually blurred, smeared, and shifted and are most commonly seen along the phase encode direction.
What is CSF pulsation artifact?
Abstract. Background and purpose: CSF pulsation artifact is a pitfall of fast fluid-attenuated inversion-recovery (FLAIR) brain MR imaging. We studied ventricular CSF pulsation artifact (VCSFA) on axial FLAIR images and its relationship to age and ventricular size.
What are motion artifacts TV?
Display motion blur, also called HDTV blur and LCD motion blur, refers to several visual artifacts (anomalies or unintended effects affecting still or moving images) that are frequently found on modern consumer high-definition television sets and flat panel displays for computers.
What is Gibbs artifact?
Gibbs artifact, also known as truncation artifact or ringing artifact, is a type of MRI artifact. It refers to a series of lines in the MR image parallel to abrupt and intense changes in the object at this location, such as the CSF-spinal cord and the skull-brain interface.
What causes susceptibility artifact?
The most likely source of the artifact is microscopic metal fragments from the burr, suction tip or other surgical instruments, but other possible causes include hemorrhage or paramagnetic suture material.
What causes corduroy artifact in MRI?
Herringbone artifact, also known as spike artifact, crisscross artifact, or corduroy artifact, is an MRI artifact related to one or few aberrant data point(s) in k-space. In image space, the regularly spaced stripes resemble the appearance of a fabric with a herringbone pattern.
What causes zipper artifact MRI?
Most of zipper artifacts result from inhomogeneities of the magnetic field caused by interferences with radio frequency from by interferences with radio frequency from various sources. Along the frequency -encode direction.
Which artifact mimics a syrinx in the spine?
Abstract. Magnetic resonance (MR) imaging of the spinal cord frequently demonstrates, especially on sagittal sections, a central stripe that mimics a true syrinx.
What is magic angle artifact?
The magic angle artifact refers to the increased signal observed when MRI sequences with short echo time (TE) (e.g., T1 or proton density spin-echo sequences) are used to image tissues with well-ordered collagen fibers in one direction (e.g., tendon or articular hyaline cartilage).
What is chemical shift in MRI?
The chemical shift phenomenon refers to the signal intensity alterations seen in magnetic resonance (MR) imaging that result from the inherent differences in the resonant frequencies of precessing protons. Chemical shift was first recognized as a misregistration artifact of image data.
