Abstract:
The aim of this study was to evaluate the common
Artifacts in MR images in Khartoum State hospitals and
detecting their Causes in order to give a solution for each if
possible. Using observation to calculate the data along 4
month on Alzytona specialist hospital and Alribat university
hospital , Artifacts in magnetic resonance images, as in
different Radiologic imaging Modalities are common and
lead to misdiagnosis or at least decrease the Image quality.
The causes are different and as a result there are many
Types of Artifacts and The result showed that the most
common Artifact is Motion record High percentage 48%, the
second common Artifacts was Phase mismmaping 18%, then
Truncation and magic angle 8% ,from coil( cross excitation)
and breathing and chemical shift 6% Through my search for
most common Artifacts in the magnetic resonance imaging
hospitals in Khartoum state we found most common
artifacts that is of patient movement (motion Artifacts) due
to differentials reasons e.g.: unconscious patient ,lack
cooperation .And Phase mismmaping Artifacts appear from
involuntary motion e.g: Brain artifacts appear because of the
phase missmapping artifacts and truncation . And also we
found Artifacts in the Pelvic because of the following reasons
Motion of the patient. It also the artifacts appears in the
Cervical because motion . And knee because magic angle and
chemical shift and motion. And lumber because chemical
shift ,motion and truncation. Accorndingly most
technologists used FSE Sequence to reducal shift and the
Artifacts. All the Examination in department is done on
Adults because of the lack of the Anesthetic for children.
