Liebrand L, Karkalousos D, Poirion E, Emmer B, Roosendaal S, Marquering H, et al.
MAGMA . 2024 Aug; 38(1):1-12. PMID: 39212832
Objective: To compare compressed sensing (CS) and the Cascades of Independently Recurrent Inference Machines (CIRIM) with respect to image quality and reconstruction times when 12-fold accelerated scans of patients with...

Ricigliano V, Louapre C, Poirion E, Colombi A, Yazdan Panah A, Lazzarotto A, et al.
Neurol Neuroimmunol Neuroinflamm . 2022 Oct; 9(6). PMID: 36229188
Background And Objectives: Recent imaging studies have suggested a possible involvement of the choroid plexus (CP) in multiple sclerosis (MS). Here, we investigated whether CP changes are already detectable at...

Tonietto M, Poirion E, Lazzarotto A, Ricigliano V, Papeix C, Bottlaender M, et al.
Brain . 2022 Sep; 146(1):182-194. PMID: 36097347
In multiple sclerosis, spontaneous remyelination is generally incomplete and heterogeneous across patients. A high heterogeneity in remyelination may also exist across lesions within the same individual, suggesting the presence of...

Lazzarotto A, Tonietto M, Poirion E, Battaglini M, Palladino R, Benoit C, et al.
Mult Scler . 2022 Jun; 28(12):1881-1890. PMID: 35708126
Objective: To investigate the clinical relevance of individual profiles of cortical and white matter lesion myelin content changes combining magnetisation transfer imaging (MTI) and 11C-PiB-positron emission tomography (PET) in patients...

Ricigliano V, Tonietto M, Hamzaoui M, Poirion E, Lazzarotto A, Bottlaender M, et al.
Eur J Neurol . 2022 Feb; 29(6):1719-1729. PMID: 35152511
Background And Purpose: Lesion remyelination preserves axonal integrity in animal models of multiple sclerosis (MS), but an in vivo demonstration of its protective effect on surrounding tissues in humans is...

Ricigliano V, Morena E, Colombi A, Tonietto M, Hamzaoui M, Poirion E, et al.
Radiology . 2021 Jul; 301(1):166-177. PMID: 34254858
Background Choroid plexuses (CPs) have been suggested as a key gateway for inflammation in experimental autoimmune encephalitis, but in vivo evidence of their involvement in multiple sclerosis (MS) is lacking....

Poirion E, Tonietto M, Lejeune F, Ricigliano V, Boudot de la Motte M, Benoit C, et al.
Neurology . 2021 Mar; 96(14):e1865-e1875. PMID: 33737372
Objectives: To explore in vivo innate immune cell activation as a function of the distance from ventricular CSF in patients with multiple sclerosis (MS) using [F]-DPA714 PET and to investigate...

Ricigliano V, Tonietto M, Palladino R, Poirion E, De Luca A, Branzoli F, et al.
Mult Scler . 2021 Feb; 27(4):528-538. PMID: 33566723
Background: Diffusion-weighted H magnetic resonance spectroscopy (DW-MRS) allows to quantify creatine-phosphocreatine brain diffusivity (ADC(tCr)), whose reduction in multiple sclerosis (MS) has been proposed as a proxy of energy dysfunction. Objective:...

Wei W, Poirion E, Bodini B, Tonietto M, Durrleman S, Colliot O, et al.
Neuroimage . 2020 Sep; 223:117308. PMID: 32889117
Multiple sclerosis (MS) is a demyelinating and inflammatory disease of the central nervous system (CNS). The demyelination process can be repaired by the generation of a new sheath of myelin...

Leroi L, Gras V, Boulant N, Ripart M, Poirion E, Santin M, et al.
Magn Reson Med . 2020 Jul; 84(6):3286-3299. PMID: 32618387
Purpose: Performing simultaneous quantitative MRI at ultrahigh field is challenging, as B and heterogeneities as well as specific absorption rate increase. Too large deviations of flip angle from the target...
