Abstract

Background : There are many variations of Time Echo (TE) value used in the cervical MRI sequence of sagital on Short Tau Inversion Recovery (STIR), according to Moeller (2010) the TE values used are 30-60 ms, according to Westbrook (2014) TE values used is more than 60 ms, whereas in Mayapada Hospital South Jakarta TE value used is 60 ms. The aim of this research is to know the difference of anatomical information of MRI cervical sagital on STIR sequence with TE variation and to find out the optimal TE value in giving anatomical information MRI cervical sagital on Short Tau Inversion Recovery (STIR) sequence.Methods : This research was conducted at Mayapada Hospital South Jakarta by varying the TE values i.e 30 ms, 45 ms, 60 ms, 75 ms, and 90 ms on the STIR sequence of sagital to 10 samples. Controlled variables in this study are TR, TI, FOV, Slice thickness, Gap, and Flip angle. The samples in this study were male or female between the ages of 20-30 years, had a normal Body Mass Index (BMT) of 18,5-22,9 kg/m2, and had no history of cervical abnormalities. The results of the image were assessed by 2 respondents Radiologists, including Corpus vertebra, Discus intervertebralis, Cerebro Spinal Fluid (CSF), and Spinal cord. Data from 2 Respondents tested with Kappa then continued with Friedman test.Results : The results showed that there was a difference of MRI cervical anatomical information on the sagital sequence of STIR with variations of TE values of 30 ms, 45 ms, 60 ms, 75 ms, and 90 ms on the anatomy of Corpus vertebra, Dsicus intervertebralis, Cerebro Spinal Fluid (CSF), and Spinal cord that has a value of p-value of 0.001 (p
