Introduction: diagnostically, MSCT Head Scan examination is aimed at revealing anatomical
images of the head and detecting abnormalities, thereby assisting physicians in making an accurate
diagnosis. In this matter, one of the common diseases encountered is stroke, particularly ischemic
stroke. Ischemic stroke signs visible on MSCT head scans include the Hyperdense Artery Sign
(HAS) and parenchymal hypodensity, which occurs when there is a blood clot (thrombus) in the
artery. This is observed as an area with higher density compared to normal blood. The aim of this
research is to evaluate how variations in window width and window level affect the MSCT Head
Scan in ischemic stroke cases.
Method: this research adopts a descriptive qualitative research design to analyse the effect of
variations in Window Width and Window Level values on anatomical image information in MSCT
Head Scans for ischemic stroke cases. The research was conducted at Langsa City Regional
General Hospital starting from October up to December 2024. As for the data collection, it was
carried out using a triangulation method, which includes among the other things direct observation,
questionnaires distributed to experienced radiology specialists (with more than five years of
experience), and document analysis of MSCT Head Scan examinations in ischemic stroke cases.
Thereafter, the collected data was be processed through stages of data reduction, data presentation
in the form of quotations, and conclusion drawing, which will be reviewed and analysed based on
the latest literature.
Results: Variations in window width (WW) and window level (WL) have a significant effect on
the quality of anatomical image information in MSCT head scan examinations. The appropriate
selection of parameters must be tailored to the diagnostic purpose to ensure optimal results. The
WW variation of 90 HU and WL of 35 HU can be considered in MSCT head scan examinations
for ischemic stroke, as it produces more optimal anatomical image information compared to other
variations of WW and WL values.
Keywords : Window Width, Window Level, Anatomical Image, Ischemic Stroke
