Clinical Trial Summary

This study investigates the specificity/sensitivity of the combined presence of cortical lesions (CLs)/leuco-cortical lesions (LCLs) and central veins sign (CVs) for multiple sclerosis (MS) diagnosis and differential diagnosis.


Description:

CLs and LCLs may be detected at 3 Tesla (T) MRI by using dedicated sequences. 3D Double inversion recovery (DIR), Phase-Sensitive Inversion Recovery (PSIR), Magnetization Prepared - RApid Gradient Echo (MPRAGE) and Magnetization Prepared - 2- RApid Gradient Echo (MP2RAGE) have all shown variable sensitivity to CLs and LCLs. The central vein sign (CVS, i.e. the detection of a central vessel in a focal lesion) has been recently proposed as a biomarker for distinguishing between MS and not and not MS. Both the presence of CL and CVs brings high sensitivity and specificity in distinguishing MS from not MS patients; whether their combination achieves higher sensitivity and specificity to MS diagnosis and differential diagnosis is to date not know. This study investigates the specificity/sensitivity of the combined presence of cortical lesions (CLs)/leuco-cortical lesions (LCLs) and central veins sign (CVs) for multiple sclerosis (MS) diagnosis and differential diagnosis.

Intervention

Other:
Image analysis/ Central vein detection
Image analysis/ Central vein detection will be performed using a fully automated approach based on an ensemble of 3D convolutional neural Networks. The method is applied to T1w, T2w and T2*w data . Results will be manually reviewed by 2 experts in CVs detection. MRI data must have been collected at 3 Tesla (3T) between 1990 and 2020 and must include T1 w, T2 w, T2-star based sequence (CVs detection).
Image analysis/ Automatic cortical lesion detection
Image analysis/ Automatic cortical lesion detection will be performed by using a convolutional neural network-based method. MRI data must have been collected at 3T between 1990 and 2020 and must include Double inversion recovery (DIR)/Phase-Sensitive Inversion Recovery (PSIR)/Magnetization Prepared - 2- RApid Gradient Echo Gradient Echo (MP2RAGE) (eventually also high spatial resolution Magnetization Prepared - RApid Gradient Echo (MPRAGE)) for cortical lesion detection.

Primary differentiation between patients with MS and clinically isolated syndrome and patients without MS (specificity) differentiation between patients with MS and clinically isolated syndrome and patients without MS by analyzing the combination of the presence of CL/LCLs and CVs as compared to the sensitivity/specificity achieved by either CL/LCLs or CVs (sensitivity) at Baseline
