Background: pathogenically, abdominal tumours refer to swellings or masses caused by neoplasms
or inflammation located in the abdominal region. In relation to which, abdominal CT scans are
performed to assess the anatomy and pathology of abdominal organs, producing cross-sectional
imaging for diagnostic purposes. Data acquisition is carried out in two stages: before the
administration of contrast media (pre-contrast) and after its administration (post-contrast). Postcontrast imaging involves several enhancement phases, with the timing of the scan determined by
the specific target being assessed. These phases include the early arterial phase, late arterial phase,
portal venous phase, and delayed phase. Furthermore, the quality of CT images is critical for
diagnostic accuracy and relates to the ability of the images to display anatomical structures as
required for clinical evaluation. Image quality can be assessed subjectively through visual
observation or objectively through phantom-based measurements. Subjective evaluation involves
direct visual inspection of the images, while objective evaluation uses standardized metrics to
quantify image quality. Subjective assessment can be performed through visual observation, while
objective evaluation involves measurements using a phantom.
Research Design: this research applies qualitative method with descriptive study approach aims to
evaluate the procedures and image quality of contrast-enhanced abdominal CT scans in intraabdominal tumour cases undertaken at Radiology Department of dr. H. Yuliddin Away Regional
General Hospital, Tapaktuan.
Research Findings: the research highlights significant differences between pre-contrast and postcontrast imaging of intra-abdominal tumours, particularly during the arterial, venous, and delayed
phases. Accordingly, contrast media effectively enhances tumour visibility, clearly delineating its
spread and boundaries, thereby aiding in precise diagnosis and treatment planning.
