Background of Research: thematically, this research focuses on evaluating the use of slice thickness
in reconstructing CT scan images of the head for non-haemorrhagic stroke cases undertaken at Cut
Nyak Dhien Meulaboh Regional General Hospital. In this matter, stroke is a rapidly developing
clinical syndrome caused by local or global disturbances in cerebral blood flow, presenting with
symptoms lasting 24 hours or more. It may lead to death without any evident cause other than vascular
disruption. In relation to which, the quality of CT scan images is crucial for obtaining clinical
information that aids in accurate diagnosis. One of the methods to achieve high-quality imaging is by
optimizing the reconstruction parameters, particularly slice thickness. Furthermore, for routine head
CT scans, the scanning parameters typically include coverage from the skull base to the vertex, with a
slice thickness of 5–8 mm, 120 kV, 190–250 mAs, and using a brain window setting.
Objective of the Study: this research aims to analyse the use of slice thickness in reconstructing head
CT scan images for non-haemorrhagic stroke cases undertaken at Cut Nyak Dhien Meulaboh Regional
General Hospital. Additionally, it seeks to evaluate the slice thickness parameters utilized in head CT
scan examinations for non-haemorrhagic stroke cases and to assess the resulting image quality of the
head CT scan examinations.
Research Design: this research employed is a descriptive qualitative study in the form of a case study,
utilizing observation and interview methods. This research was conducted at Radiology Department of
Cut Nyak Dhien Meulaboh Regional General Hospital starting from November up to December 2024.
Thereafter, the research utilized a Siemens 16-slice CT scanner and included a sample of 5 patients
diagnosed with non-haemorrhagic stroke. As for the data for this research, it consisted of secondary
data, which had been previously processed and stored.
Research Results: this research found that reconstruction using a slice thickness of 5 mm is suitable
for head CT scan examinations in cases of non-haemorrhagic or ischemic stroke. Greatly, this slice
thickness effectively displays clear anatomical details, providing sufficient support for the diagnostic
process in non-haemorrhagic stroke cases.
Keywords: CT scan, Slice Reconstruction, Non-Haemorrhagic Stroke
