Abstract
Quantitative Magnetic Resonance Imaging (MRI) is generally used to obtain information about the characterization of body tissues in MRI scanning. The variation of parameters, such as repetition time (TR) and echo time (TE), will produce different image results. The previous study has discussed the effect of variation of TR values on MRI images, while TE is one of the parameters that have an essential role in the formation of MRI images. This study will discuss the effect of variation of TE on MRI images. The samples were made of agarose gel with a concentration of 0.5% to 5% and distilled water. Samples were scanned using MRI 1.5 Tesla and data were processed using image processing software. From data processing, signal intensity was used to obtain T2 relaxation time and signal-to-noise ratio. The agarose concentration and TE variation affect signal intensity from each sample. The signal intensity and SNR decrease with increasing TE values. The agarose of lower concentration gives the hyperintensity image and yields higher T2 relaxation time.
