Background: Multiple sclerosis (MS) is a demyelinating disease, involving almost 2.5 million people around the world. There are different MR pulse sequences, which are used to detect MS plaques. Objectives: This study aimed to compare, T2 weighted, short-tau inversion recovery (STIR) and phase-sensitive inversion recovery (PSIR) pulse sequences, for detecting cervical spinal cord lesions in MS patients. Results: The LCR and LNR of the T2 and PSIR were the same (LCR of 0.04, -0.03 and LNR of 2.74, -2.09 respectively), just the intensities were reverse. STIR had a significantly different LCR and LNR [0.23 (P < 0.001) and 22.7(P < 0.001) respectively], hence it was better in diagnosing cervical cord MS plaques. Conclusion: According to the results, using 1.5 T MRI machine, it implies that the STIR pulse sequence was the best pulse sequence in comparison to T2 and PSIR in detecting cervical cord MS plaques.
