Magnetic Resonance Imaging (MRI) Double Inversion Recovery Sequence in Diagnosis of Multiple Sclerosis

Abstract

Aims: The current work aimed to assess the diagnostically value of Magnetic Resonance Imaging (MRI) Double Inversion Recovery (DIR) sequence in diagnosing of multiple sclerosis. Methodology: This study conducted on (42 patients) from the Diagnostic Radiology and Medical Imaging Dep. at Tanta University Hospital in the period from March 2018 to December 2019. Results: In accordance to the total lesions loads, it was found that DIR was higher significantly than T2WI (P-value= 0.003 with a relative gaining of 22%), we found that double inversion recovery (DIR) sequence was higher significantly to FLAIR regarding the number of diagnosed lesions in 3 anatomical areas (Mixed W-GM, cortical and infra-tentorial) with relative gaining of 28%, 85% and 63% respectively. A non-significant change was found among the two sequences regarding peri-ventricular white matter, deep white matter and juxta-cortical lesions detecting. Conclusion: Conventionally MRI has corner-stone roles in diagnosing, characterizing and following-up of multi-sclerosis. Finally, we concluded that DIR can be used as a addition to or even as an alternative for typical T2 and FLAIR. Therefore, we strongly recommend the addition of DIR sequences in the everyday MR protocol of MS cases.
