Artifact Information
NAME
Central point, DC artifact, DC offset
DESCRIPTION
Bright spot
REASON
DC voltage offset
HELP
Call the service
This artifact appears as a bright spot (or zipper line) in the image center. Central point artifacts are caused by a DC offset in the hardware. MRI scanners normally offer a software compensation (DC correction, baseline correction) for prevention.
mri safety guidance
Image Guidance
Take care for a constant temperature. If the problem increases or keeps on existing, it should be addressed to the service.

This artifact looks like a pixel at the exact center, which is brighter or darker than the surroundings by the Fourier transformation of a constant raw data offset.

Quick Overview
Artifact Information
NAME
Radio frequency quadrature
DESCRIPTION
Bright spot in the center of the image, ghosting
REASON
RF detection circuitry problem
HELP
Call the service
Radio frequency quadrature artifacts occur when the detector channels of the quadrature detector are disturbed.
A DC offset of one amplifier output can e.g., produce a bright point in the center of the field of view (see also central point artifact), or a higher gain of one detector channel can generate diagonally ghosting.
mri safety guidance
Image Guidance
Radio frequency quadrature artifacts are technical faults and must be eliminated by the service.
