Simultaneous T2-FLAIR and T1 Brain MRI With ENRAGED FLAIR in Multiple Sclerosis (ENRAGED FLAIR)

2. september 2026 opdateret af: Henric Ryden, Region Stockholm

Evaluation of a Combined MR Sequence for Simultaneous T2- and T1-Weighted Brain Imaging in Multiple Sclerosis

This study will evaluate a new brain MRI technique called ENRAGED FLAIR in patients with multiple sclerosis. MRI is central in the diagnosis and follow-up of multiple sclerosis because it can show inflammatory lesions in the brain. A standard MS brain MRI examination usually includes T2-FLAIR images, which are used to detect and assess MS lesions, and T1-weighted images, which provide anatomical information and help with interpretation of lesion location.

These image types are usually acquired as separate scans. ENRAGED FLAIR is designed to acquire both T2-FLAIR and T1-weighted images during the same MRI sequence. The purpose of this study is to compare ENRAGED FLAIR with standard clinical MRI in patients with multiple sclerosis.

Adult patients with multiple sclerosis who are already scheduled for a clinical brain MRI may be asked to participate. Participants will undergo one additional MRI sequence during the same visit. No extra contrast agent will be given, and no extra visit is required. The additional scan is expected to increase the examination time by about 5 to 10 minutes.

The study will assess whether ENRAGED FLAIR provides image quality and MS lesion visualization comparable to standard MRI. If successful, this technique may help shorten future MRI examinations for patients with multiple sclerosis while preserving clinically useful image information.

Detaljeret beskrivelse

Multiple sclerosis (MS) is commonly monitored with brain MRI. T2-FLAIR imaging is central for detecting and following MS lesions, while T1-weighted imaging provides anatomical information that supports lesion localization and interpretation. In routine clinical MRI, these contrasts are usually acquired as separate sequences, which increases examination time.

ENRAGED FLAIR is a combined MRI acquisition designed to generate both 3D T2-FLAIR and T1-weighted brain images from a single sequence. The method uses otherwise unused recovery time in a FLAIR acquisition to acquire T1-weighted data. This may improve scan efficiency while preserving the clinically important information from both contrasts.

This study is a prospective intra-individual comparison in adult patients with MS undergoing clinically indicated brain MRI. Each participant will undergo standard clinical MRI sequences and one additional ENRAGED FLAIR acquisition during the same examination. No additional contrast agent or study visit is required.

Images from ENRAGED FLAIR will be compared with standard clinical T2-FLAIR and T1-weighted images. The evaluation will focus on MS lesion visualization, diagnostic image quality, and whether the simultaneously acquired T1-weighted images provide sufficient anatomical information for interpretation. Because each participant undergoes both standard MRI and ENRAGED FLAIR, each participant serves as their own control.

The study is intended to determine whether ENRAGED FLAIR can provide image quality comparable to standard MRI in MS while potentially enabling shorter future brain MRI protocols.

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: ENRAGED FLAIR MRI
Participants undergo standard clinical brain MRI and one additional ENRAGED FLAIR MRI acquisition during the same examination. ENRAGED FLAIR images will be compared with standard clinical T2-FLAIR and T1-weighted images acquired in the same participant.
Diagnostisk test: ENRAGED FLAIR MRI
ENRAGED FLAIR is a combined MRI acquisition designed to generate both 3D T2-FLAIR and T1-weighted brain images from a single sequence. The additional sequence is acquired during the same clinical MRI examination and does not involve extra contrast agent or an additional study visit.

Tidsramme: At image review after the MRI examination, up to 12 months after enrollment
Blinded neuroradiologists will compare ENRAGED FLAIR-derived T2-FLAIR images with standard clinical T2-FLAIR images for MS lesion assessment and routine clinical interpretation using a 5-point relative diagnostic image quality scale. Scores range from 1 to 5: 1 = standard clinical T2-FLAIR strongly preferred, 2 = standard clinical T2-FLAIR slightly preferred, 3 = no preference/equivalent diagnostic quality, 4 = ENRAGED FLAIR-derived T2-FLAIR slightly preferred, and 5 = ENRAGED FLAIR-derived T2-FLAIR strongly preferred. Higher scores favor ENRAGED FLAIR.
