Abstract

Background: CT scans with contrast media administration have been used to confirm the presence of pathology in the blood vessel of the brain. High accuracy and fast scanning time produced by CT scans make this modality the main choice in assessing aneurysm pathology in the brain. Technological advances and the development of CT-helical image acquisition techniques have enabled neuroradiologists to evaluate brain aneurysms in a short time. Magnetic resonance (MR) angiography has also been reported to be useful in the diagnosis of brain aneurysms, but it is generally more time-consuming than 3D CTA, and MRI is very sensitive to movement artifacts.Methods: This research is qualitative research with an observational approach that aims to determine the management of carotid-cerebral CTA artery examination in Premier Bintaro Hospital. Unstructured interviews and documentation are used as study instruments to complete the required data.Results: Cerebral Angiography CT examination technique in Premier Bintaro Hospital uses a bolus tracking scanning technique with ROI monitoring of the Carotid Internal Artery and using triggering of 100-120 HU as a peak enhancement to ROI monitoring. This has been proven to produce optimal enhancement in the Circulus of Willis (CoW) region as Volume of Investigation (VOI) in cerebral Angiography CT-Scan. Post-processing is done by displaying images ranging from axial pre-contrast, axial post-contrast, study (pathology), MIP (Axial, coronal, sagittal), Region of Interest MIP (structure labeling), 3D VRT-bone removal.Conclusion: Scanning technique with bolus tracking and ROI monitoring of the Internal Carotid Artery and using triggering of 100-120 HU as a peak enhancement on ROI monitoring can display the arterial artery image very well so that it can be post-processed easily without reducing quality and related image information.

Abstract

CT Scan is an excellent technique in assessing anatomical structures, anatomical abnormalities, and visualising the presence or absence of pathological tissue in the four sinuses and their extensions. One of the important parameters on CT Scan is slice thickness. Slice thickness is a thickness of the slice that can be adjusted according to clinical requirements with a variation of values from 1 to 10 mm. The purpose of this study is to determine the effect of slice thickness variation on anatomical information of CT Scan paranasal sinus coronal section in rhinosinusitis and slice thickness variation that produces the most optimal anatomical information. This study is an analytical quantitative study with an experimental approach conducted on 10 samples who performed CT scan examination of paranasal sinus in rhinosinusitis using slice thickness variations of 0.6 mm, 1 mm, 1.5 mm and 2 mm. Based on the results of Friedman test and Wilcoxon Post Hoc test, the p value is 0.0001 (p<0.05) which means there is an effect of using slice thickness variation on anatomical information. The mean rank value in the Friedman test for slice thickness variations of 0.6 mm is 3.70, 1 mm is 3.13, 1.5 mm is 1.85, and 2 mm is 1.32 so based on the test results, slice thickness variation that shows the most optimal anatomical information is 0.6 mm.

Abstract

Radiotherapy is a treatment for cancer using high-energy radiation, usually X-rays. The type and amount of radiation received is calculated by oncologists and medical physicists to destroy cancer cells, these cells are abnormal cells. This stops the cancer cells from dividing properly and as a result the cancer cells are destroyed. This treatment is planned to protect healthy tissue as much as possible from radiation which has destructive properties, however some healthy tissue can be affected which will later cause side effects. Radiotherapy uses a Linear Accelerato (LINAC) device in its treatment. The LINAC can produce two beams, namely photons and electrons. Photon beams are usually used to illuminate tumors in deeper tissue in the body, for example breast cancer, cervical cancer and nasopharyngeal cancer, while electron beams are used for cancer therapy in surface tumors. The role of radiotherapy in the treatment of breast cancer has a long and controversial history. One of the first clinical trials ever conducted, it began in 1949, and remains the subject of new trials still being initiated today. Early trials clearly showed that radiotherapy reduced local recurrence, with a relative risk reduction now known to be approximately 70%, but a reduction in recurrence rates did not translate into a reduction in mortality. Theories explaining this difference are numerous, including the detrimental effects of radiotherapy on immune function.
