Background: The component that can affect image quality is noise. Noise in CT Scan images comes from random variations in photon detection. Scan time is the time it takes for x-rays to exit for data collection of each slice. Pitch is one of the important component parameters in the CT Scan protocol and fundamentally affects the quality of the resulting image, as well as the time required for scanning. The use of pitch in the Radiology Installation of Ibnu Sina Islamic Hospital Pekanbaru in the head CT Scan examination is 0.55. The pitch value variations used by the author in this study are pitch 0.55, 0.75, 1, 1.25 and 1.5.Methods: This type of research is quantitative research using an experimental approach. The study was conducted to determine the effect of pitch value variation on image quality (noise) and scan time using a water phantom on head CT Scan examination protocol using pitch 0.55, 0.75, 1, 1.25 and 1.5. A sample of 10 CT Scan images was taken, and the image quality (noise) was measured by identifying a specific region in the image (Region of Interest or ROI), while the scan time value was observed from the consul monitor. Data analysis was performed using one-way ANOVA statistical test with a significance level of 5%.Results: The results show that there is a significant difference in image quality (noise) on pitch value variation, with a significance level of 0.004, and there is also a significant difference in scan time on pitch value variations with a significance level of less than 0.001. Conclusions: Based on the conclusion, pitch 1 is the value that produces optimal noise level and scan time in head CT Scan protocol using water phantom.

Hemorrhagic stroke is the rupture of blood vessels in the brain, resulting in reduced blood flow (ischemia) and hypoxia. One of the disorders that can be diagnosed through sophisticated modalities is a CT scan, because it can be done quickly and accurately when evaluating bleeding in the brain. The slice thickness used in CT scans of the head in hemorrhagic stroke cases is 5 mm-10 mm, carried out using a one range protocol, namely from the basic cranii to the vertex. Slice thickness is the thickness of the slice that can be selected according to clinical needs. The factors used to evaluate image quality are spatial resolution, resolution contrast and noise. This research is quantitative by taking an experimental approach to analyze the effect of using slice thickness variations of 3mm, 4mm and 5mm on image quality (spatial resolution, resolution contrast and noise) on CT scans of the head in cases of hemorrhagic stroke of 10 samples. Based on the results of the research carried out, the researchers can conclude according to the overall results of the Friedman test that there is an influence on the image quality of CT scans of the head in hemorrhagic stroke cases using slice thickness variations of 3mm, 4mm and 5mm on spatial resolution, contrast resolution and noise. So based on the results of the Friedman test per image quality, there is a difference in the image quality of CT scans of the head and cases of hemorrhagic stroke which use slice thickness variations of 3mm, 4mm and 5mm. Based on the results of the mean rank of the Friedman test, slice thickness 5mm has a mean rank of 2.88 with the highest value. Based on the results of this study, researchers can recommend that CT scans of the head in cases of hemorrhagic stroke use a slice thickness of 5 mm with the aim that the image quality results in CT scans of the head in cases of hemorrhagic stroke look clear and good.

Knee injuries are often encountered in general practice and in hospitals. One injury that can occur is injury to the meniscus which causes a meniscus tear. The meniscus is a fibro cartilage disc which is the content of the knee joint and is divided into two, namely the lateral meniscus and the medial meniscus. To confirm the diagnosis of injured ligaments is by carrying out an MRI examination. MRI examination of the knee joint using T2* Multi Echo Rechalled Gradient Echo can provide optimal images in cases of meniscus tears. MRI examination of the knee joint using MEDIC is very useful for cervical imaging, cartilage, joint and musculoskeletal examination. The advantage of the MEDIC sequence is that it can be used for 2D and 3D imaging and can reduce chemical shift artifacts. Based on the journal taken by the author, the sequence needed to clinically show a meniscus tear on an MRI Knee Joint examination is sagittal STIR and sagittal T2 MEDIC. then the most optimal sequence in clinically showing a meniscus tear is chosen to increase the efficiency of the examination time. The type of research used is qualitative research with a case study approach. The subjects used in this research were 3 Radiology Specialist Doctors and 3 Radiographers. The STIR and T2 MEDIC sequences on the MRI Knee Joint examination have their respective roles in confirming the diagnosis of Tear Meniscus. The STIR sequence plays a role in assessing the Anterior Cruriated Ligament, Posterior Cruriated Ligament, radiologists also want to see edema or swelling that occurs in the patient's genu. The MEDIC T2 sequence plays a role in assessing the medial and lateral meniscus, the radiologist also wants to see blood production in the patient's genu. The STIR and T2 MEDIC sequences in the MRI Knee Joint examination at the Balimed Denpasar Hospital installation are able to confirm the diagnosis, especially in the clinical Tear Meniscus, because with these two sequences, the picture of the Medial Meniscus, Lateral Meniscus, Anterior Cruriated Ligament, Posterior Cruriated Ligament, product blood and edema can be clearly seen.

Background: Abdominal MSCT examination is a type of radiodiagnostic examination that uses the MSCT device. Considering that the abdomen is close to organs that have radiosensitive properties such as the gonads and ovaries, it is necessary to monitor the radiation dose received so that it does not exceed the predetermined I-DRL value. The prevalence of contrast Abdominal MSCT examinations in the Radiodiagnostic Installation at Dr Hasan Sadikin Bandung Hospital was recorded during the last 3 months, there were 327 Contrast Abdominal MSCT examinations out of a total of 880 examinations with a percentage of contrast Abdominal MSCT examinations of 0.37%. This proves that contrast Abdominal MSCT examinations are often carried out but evaluation has never been carried out regarding the radiation dose received by the patient. Method: The type of research used in this research is descriptive quantitative with an observational approach by collecting data from patients with contrast Abdominal MSCT examinations during the period January-March 2023 with a sample of 128 patients. The local DRL value is calculated using the 2nd quart formula in the SPSS statistical application, then this local DRL value is compared with the I-DRL value determined by BAPETEN. Results: Calculation of the 50th percentile value of CTDIvol and DLP on 128 samples. The results show a CTDIvol value of 15.91 mGy and DLP of 740 mGy*cm. The DRL (50 percentile) values based on gender are 13.71 mGy and 743 mGy*cm for men, and 17.74 mGy and 792 mGy*cm for women. Based on abdominal thickness, patients with a thickness of 10-19 cm have values of 12.19 mGy and 587 mGy*cm, while patients with a thickness of 20-30 cm have values of 22.57 mGy and 965 mGy*cm. For the most clinical cases (Ca Recti) the values were 11.27 mGy and 586 mGy*cm. Conclusion: The 2nd quartile value (50 percentile) of CTDIvol and DLP received by patients during the Contrast Abdominal MSCT examination at the Radiodiagnostic Installation of RSUP Dr. Hasan Sadikin Bandung is in accordance with the standard values set by BAPETEN/I-DRL 2021.
