Background: this research explores knowledge regarding ureter stones, a critical factor in
determining accurate treatment approaches, such as utilizing non-contrast abdominal CT scans. In
relation to which, predicting stone fragility through imaging modalities can guide interventions
like Extracorporeal Shock Wave Lithotripsy (ESWL) and endoscopic laser lithotripsy. It is also
beneficial for planning dietary therapy and other metabolic strategies. In this matter, urinary tract
stones exhibit varying characteristics in terms of density and shape.
Purposely, this research aims to develop the best techniques for non-contrast CT scans urography
in diagnosing ureter stones, evaluate examination techniques, and assess image reconstruction
quality to achieve optimal imaging results.
Research Design: this research applies a quantitative method with descriptive study approach to
evaluate the impact of image quality on spatial resolution, contrast resolution, noise, and artifacts.
This research was undertaken at Radiology Department of Cut Meutia Regional General Hospital,
North Aceh Regency starting from October up to November 2024, the study involved 10 Pasiens
undergoing non-contrast CT scans for ureter stones. Thereafter, images were acquired in axial and
coronal planes using the Siemens Somatom 64-Slice CT scanner. Image quality was assessed by
the respondents based on spatial resolution, contrast resolution, noise, and artifacts.
Results of research: this research concludes that non-contrast abdominal CT scan imaging for
clinical ureter stones based on the result get an average score of 4.80, indicating hyperdense
visualization with very clear depiction. Therefore, it was scored an average of 4.80, categorized as
hyperdense with highly distinct boundaries visible. The next assessment gets an averaged score of
4.80, indicating very clear hyperdense visualization. Scored 4.60, showing very clear hyperdense
visualization of the stone and surrounding tissues. Furthermore, it scores an average of 4.40,
demonstrating very clear visualization of ureteral obstructions.
Keywords: Spatial resolution, contrast resolution, noise, artifacts
