Abstract

Background: One of the modalities used to diagnose chronic rhinosinusitis is MSCT Scan. In MSCT Scan, there are several scanning parameters used, namely slice thickness and reconstruction increment. This study aims to determine the effect of variations in slice thickness reconstruction and increment reconstruction on the anatomical image information of MSCT scans of coronal paranasal sinuses in cases of chronic rhinosinusitis. Method: This type of research is quantitative research with an experimental approach carried out at the radiology installation of Prof. RSUP. Dr. I.G.N.G Ngoerah in June-July 2023. This study used 10 samples and each radiograph was reconstructed with 6 variations of slice thickness reconstruction and increment reconstruction. Results: Based on the results of the overall anatomical Friedman test, a p value of 0.000 was obtained (p value <0.05), which can be interpreted as Ho being rejected and Ha being accepted so that there is a difference in overall anatomical image information on the MSCT scan of the coronal paranasal sinuses with 6 variations of slice thickness and reconstruction. increment reconstruction in cases of chronic rhinosinusitis. Based on the Wilcoxon test, it also shows that each variation has a p value <0.05, which means there are differences in anatomical image information for each variation. Conclusion: Based on this research, it shows that there are differences in the anatomical image information of MSCT scans of paranasal sinus coronal sections with variations in slice thickness reconstruction and increment reconstruction in cases of chronic rhinosinusitis, and variation 2 produces the most optimal anatomical image information. Based on the Wilcoxon test, it also shows that each variation has different anatomical image information.

Abstract

Background:Non-hemorrhagic strokeis a cerebrovascular disease that occurs when the blood supply to part of the brain is suddenly interrupted by occlusion, usually caused by thrombosis, embolism, and focal hypoperfusion which can cause a reduction or disruption in cerebral blood flow (CBF) and affect neurological function due to lack of glucose and oxygen. Computed tomography scanning (CT Scan) of the head is a special examination of the head that uses tomography techniques with X-ray beams penetrating the patient's head from various directions using a computer system to produce anatomical images in axial, sagittal and coronal planes..One of the parameters for a CT scan of the head is Increment Reconstruction. Reconstruction Increment is the distance between reconstruction images in volume data. Method: Typeresearch is quantitative with an experimental approach, carried out in July-August 2023 at Bali Mandara Regional Hospital. The population and sample of this study were 10 patients with indications of non-hemorrhagic stroke. Results :research results from the overall Friedman test on CT scans of the head with clinical non-hemorrhagic stroke using variations in reconstruction increments of 0.5mm, 0.9mm, 1.5mm, 2mm, the results of the most optimal anatomical image information in producing images from 4 variations of increments, namely in the 2mm increment reconstruction which has the highest mean rank value, namely 3.30 in the thalamus area, 3.40 in the lateral ventricle area, 3.25 in the white matter area, 3.40 in the gray matter area, 3.40 in the lesion area hypodense/infarction of 3.25. Conclusion:From the results of the Friedman test on CT scans of the head with clinical non-hemorrhagic strokes using variations in reconstruction increments of 0.5mm, 0.9mm, 1.5mm, 2mm against anatomical criteria, the most optimal value in producing an image is at a reconstruction increment of 2mm which has the highest mean rank value.

Abstract

Pengendalian mutu (Quality Control/QC) pada CT Scan adalah langkah penting untuk memastikan kualitas gambar diagnostik yang optimal serta mengurangi risiko paparan radiasi. Penelitian ini bertujuan untuk menilai kesesuaian CT Number pada air dan mengevaluasi keberadaan artefak pada MSCT di Rumah Sakit Hewan Sunset Vet Kuta. Metode yang digunakan adalah pendekatan deskriptif kuantitatif dengan desain observasi. Sampel penelitian terdiri dari 7 slice citra dengan pengukuran CT Number dilakukan pada 5 titik menggunakan phantom air. Evaluasi artefak dilakukan secara visual pada semua slice citra. Hasil penelitian menunjukkan bahwa CT Number pada air berada dalam batas toleransi BAPETEN, yaitu ±4 HU untuk akurasi dan ±2 HU untuk keseragaman. Tidak ditemukan artefak yang signifikan pada slice citra.Kesimpulannya, sistem MSCT yang diuji memenuhi standar kendali mutu, sehingga mampu menghasilkan kualitas gambar yang andal untuk diagnosis kesehatan hewan.
