Motion Artifact Mimics Subdural Hemorrhage on CT Scans: A Case Series
Abstract
The aim of this paper is to show a common phenomenon seen in brain computed tomography scans. This phenomenon is seen when the patient slightly moves during the brain scan which creates a motion artifact that appears like pathology and the radiologists might misdiagnose the case as a false positive case. A slight motion artifact appeared as a subdural hemorrhage in five cases. Some of these cases came to the hospital as road traffic accident cases, while others have only suffered a chronic headache. In this case series, five cases are presented, scanned again to rule out any pathology, and these cases are discussed in this paper to find any common pattern among these cases.
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
