Abstract

Time Repetition (TR) and Echo Train Length (ETL) are the parameters in MRI that can be adjusted by a radiographer to affect image quality, anatomic information, and scan time. There are various TR and ETL adjustments used for lumbar MR imaging. This study is to determine the differences in the combination of TR and ETL to the anatomic information of the images. This is an experimental research. Data were collected from 30 patients with variations of TR1000, TR2000, ETL13, ETL17, and ETL21. The Images were evaluated by radiologists. Evaluation of the images were conducted on the corpus vertebrae, inter vertebral disc, conus medullar, cerebrospinal fluid and ligamentum flavum. The data were analyzed using Friedman test with 95% CI. The results show that the combination of TR and ETL variations affect the anatomic information of T2WI TSE sagittal lumbar MRI. The Friedman test shows differences of image anatomic information from variations of the combination of TR and ETL (p-value = 0.001). The Combination of TR2000 ETL17 produces optimal image information.
