Abstract

The exposure factor is one of the important parameters in optimizing the radiographic examination. This study aimed to analyze the value of the Signal To Noise Ratio (SNR) against the use of the 15% kV rule method in the examination of Chest AP Supine. Descriptive quantitative research method conducted in the laboratory of the Department of diagnostic imaging and radiotherapy, Health Polytechnic of the Ministry of Health, Jakarta 2, using computer radiography, X-rays, piranha radiation detectors, and anthropomorphic phantoms, with statistical analysis of the Pearson test to determine the level of relationship between SNR and Exposure Index (EI). Against the 15% kV rule method, then the one-way ANOVA test to determine the effect of the 15% method on changes in value. The results of the Pearson test obtained a p-value of 0.820 with a strong relationship between SNR and EI against the 15% kV method. Therefore, using an exposure factor of 15% kV rule method makes it possible to control the SNR and EI values. The one way ANOVA test has a p-value of 0.943, so there is no significant difference in the SNR value to changes in the exposure factor with the 15% kV rule method so that the optimization of the exposure factor with the 15% kV rule method can reduce the radiation dose while maintaining the image quality radiographic

Abstract

Magnetic resonance imaging (MRI) is a diagnostic examination modality in medicine using a magnetic field without using X-rays, MRI has the advantage of being able to create images and can show clearer and more sensitive anatomical differences in soft tissues in the body such as the brain,Bone marrow and musculoskeletal. An MRI machine can produce diagnostic images of the inside of the human body, both in sagittal, coronal and transverse sections, without using ionizing radiation (X-rays) and also without using radioactive substances, but based on the principle of magnetic resonance of the hydrogen atom to reveal anatomy and pathology. clinical diagnosis, one of which is Hernia Nucleus Pulposus in the Cervical vertebrae. Hernia  Nuecleus pulposus is a condition of biochemical ad physical changes in the spinal disc tissue caused by degeneration in old age,or acute external pressure that causes a bulge into the spinal canal,putting pressure on the durameter or nerve roots, thereby triggering symptoms of neurological pain. The use of the Dixon sequence was proposed for the assessment of metaphyseal bone marrow water water content,with a short scan time. Dixon sequence imaging can be used for fat suppression in the extremities and spine, but also quantification of fat in the bones.. The research method used is descriptive research with an observation approach. Data collection was carried out from 01 January 2022 to 28 February 2023 using a Mr. Philips aircraft with a power of 3 Tesla. The sample of patients used in this study were 5 patients with vertebral complaints. Data collection was carried  out  through observation,interviews and documentation. Cervical MRI examination with clinical Hernia Nucleus Pulposus using a Philips 3 Tesla MRI machine has an examination procedure with a Survey sequence design, Myelo, Sagittal TSE T2 dixon, Sagittal TSE T1, Coronal TSE STIR, Axial TSE TA, and axial mFFE
