The lumbar is an organ with excellent mobility in movement but is very susceptible to interference. MRI is one of the modalities used to scan the lumbar with the results in the form of images. The optimal image is an image that has the good image quality and effective scanning time. Based on this, this study aims to determine the optimization of the combination of NSA and ETL to obtain optimal images and to determine the variation of NSA and ETL values that have optimal SNR and effective imaging time in lumbar MRI. The study was conducted by changing the combination of NSA and ETL in the sagittal section of the lumbar MRI scan T2 Fast Spin Echo (FSE). The image results are obtained by region of interest (ROI) to determine the SNR as a reference for image quality. ROI was performed on the corpus tissue, invertebrate disc, spinal cord, and CSF. The study found that SNR will increase when NSA and ETL are increased, while scanning time will increase when NSA is increased, but will decrease when ETL is increased. For the ANOVA statistical test, the results of the SNR value did not have a significant difference from the combination of NSA and ETL to the determination of the SNR value, while for the statistical test at the time of scanning there was a significant difference. These results indicate that the optimal combination of NSA and ETL for MRI examination of lumbar images is a combination of NSA 2 and ETL 32. [ABSTRACT FROM AUTHOR] |
