Background: diagnostically, Multislice Computed Tomography (MSCT) is a diagnostic
modality that utilizes multiple rows of detectors which rotate either stationary or
continuously, in conjunction with the movement of the patient on the examination table,
thereby it produces various axial image slices. In this matter, the advantages of CT
scanning include among the other things high scanning speed, high resolution, and
volumetric acquisition, which can provide more detailed imaging information. In relation
to which, the use of slice thickness can enhance spatial resolution, which is beneficial for
imaging examinations of complex organ structures, such as the paranasal sinuses and
mastoid. CT scanning of the paranasal sinuses in the cases of inflammation or infection of
the nasal and sinus structures (rhinosinusitis) provides detailed anatomical imaging of the
paranasal sinuses and osteomeatal complex of the nasal cavity, which is essential for
establishing an accurate diagnosis. One of the scanning parameters used in this
examination is slice thickness.
Research Method: this research applies a qualitative research design with a case study
approach, aimed at providing a detailed description of real-world conditions in the field.
As for the data collection methods, they include observation and questionnaires. The data
used in this research are secondary data, and then the data analysis is performed using an
interactive model analysis approach.
Results: The results of the research indicate that there are differences in slice thickness
affecting image quality in CT scans of the paranasal sinuses in rhinosinusitis cases,
specifically with slice thicknesses of 1mm, 3mm, and 5mm. The 3mm slice thickness
demonstrated the best performance, showing the highest spatial resolution and contrast
resolution, with an average value of 5.60.
Conclusion: for CT imaging of the paranasal sinuses, a slice thickness of 3mm is highly
recommended for axial slices, as it provides high-quality images that are useful for the
anatomical evaluation of the paranasal sinuses.
