A new radiotracer called [F-18]PBR06, used in positron emission tomography (PET) imaging, helps detect changes in the brain’s grey matter that are linked to progressive forms of multiple sclerosis (MS), a study shows. The findings support [F-18]PBR06’s potential for detecting signs of disease progression even before patients show…

DELIVER-MS Trial Recruiting RRMS Patients to Help Improve Treatment Decision-making What’s the best way to attack multiple sclerosis when it’s first diagnosed? Do you hit it hard and fast using the most effective disease-modifying therapy (DMT), or do you start with a lower efficacy DMT and slowly ramp up?…

Did you know that not all magnetic resonance imaging (MRI) exams are of equal quality? Walmart officials know this, and they are concerned that poor exams given to their employees are costing the company money. Because people with multiple sclerosis are likely to have several MRIs over…

Non-contrast MRI Effective in Monitoring Progression of MS, Study Shows There’s been increased interest in the risks versus the benefits of using gadolinium to make lesions more visible on an MRI. The U.S. Food and Drug Administration issued an advisory last year raising the level of…

The evaluation of disease progression in multiple sclerosis (MS) patients through magnetic resonance imaging (MRI) can be performed without the use of a contrast agent, new research has shown. These findings suggest that routine use of contrast-enhanced MRI is unnecessary for most follow-ups with MS patients, reducing both imaging…

A method based on cerebrospinal fluid measurements and magnetic resonance imaging (MRI) can aid in stratifying patients with multiple sclerosis (MS) at the time of diagnosis, which may help identify a tailored therapeutic approach for each patient from early disease stages. The data was presented by Roberta Magliozzi, from…

Two new magnetic resonance imaging (MRI) biomarkers — called central vein sign and paramagnetic rim sign — could be useful for differentiating true radiologically isolated syndrome (RIS) patients from those with mimicking features, new research shows. The findings were presented at the Americas Committee for Treatment and Research in Multiple…

The rate of spinal cord tissue loss is a strong indicator of conversion from relapsing-remitting multiple sclerosis (RRMS) to secondary progressive MS (SPMS), according to a finding presented at the fourth annual Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum 2019. The forum…

Aubagio (teriflunomide) seems to be superior to Tecfidera (dimethyl fumarate) in slowing whole brain shrinkage in patients with relapsing multiple sclerosis (MS), a new Phase 4 clinical trial shows. However, Aubagio and Tecfidera have similar beneficial effects in achieving other clinical goals and magnetic resonance imaging (MRI) parameters,…

Almost one in five patients diagnosed with multiple sclerosis (MS) and referred to one of two MS-specialized centers in the U.S. were found to not have the disease, a study at those two centers reported. Migraine was the most common correct diagnosis eventually given these people. The retrospective study…

The progressive decline in brain volume in multiple sclerosis (MS) patients, despite treatment with the disease-modifying therapy Tysabri (natalizumab), is driven by atrophy — shrinkage due to the degeneration of cells — in gray matter and not white matter structures, a new study reports. This finding points to new markers…

Since the first of this year, hospitals in the U.S. have been under new government orders. They must make their “list price” for specific services — things like an MRI or an infusion — available to the public by posting them online. The requirement was announced last summer. In…

Artificial Intelligence May Help Reduce Dosage of Gadolinium in MRIs, Researchers Suggest There’s been concern recently about the accumulation of gadolinium in the brains of people who’ve had MRIs. Gadolinium is the dye that’s used to provide the “contrast” that can highlight lesions in the brain that might…

Artificial intelligence can help reduce the amount of gadolinium used as a contrast agent in MRI (magnetic resonance imaging) scans, preventing the agent’s potential toxicity when accumulated in body tissue, including the brain and bones, each time it is used, researchers suggest. The finding is of particular importance for…

Diabetes, hypertension, and active smoking correlate with more brain shrinkage in multiple sclerosis (MS) patients, a new study shows. The study, “Assessing the burden of vascular risk factors on brain atrophy in multiple sclerosis: A case- control MRI study” was published in the journal Multiple Sclerosis and Related Disorders.

Although brain atrophy — the loss of brain volume — is an increasingly important measure in multiple sclerosis trials and treatment outcomes, MS patients have a limited understanding of its role in disease progression, a survey reveals. This finding was detailed in the presentation “…

Lesions in the infratentorial region of the brain at the onset of clinically isolated syndrome (CIS) and lesions in white matter one year after CIS onset are associated with worse disability 30 years later, a study reports. The study, “Early MRI predictors of long-term multiple sclerosis outcomes:…

Often-overlooked MRI Signal May Aid in Early Diagnosis of MS, Other Brain Conditions, Study Suggests A part of an MRI scan that radiologists call a “background signal” is what’s being looked at. It’s usually ignored because the signal doesn’t seem to change even when a patient is…

Scientists have found that a usually-overlooked signal from MRI scans indicates brain regions of nerve cell death and may help in the understanding of brain development and the early diagnosis of brain disorders like multiple sclerosis (MS),…

A couple weeks ago, I went to my neurologist’s office early for my annual MRI. It’s never a pleasant experience. Even after 14 years, it’s still as unsettling as it was the first time. It’s not the tightness of the space that gets me or the sensations and sounds.

High blood pressure and heart disease are linked to greater loss of brain mass, or atrophy in white matter and whole brain volume, in people with multiple sclerosis (MS), a study following patients for five years shows. No association between cardiovascular disease and…

The number, location, and size of lesions can help predict the risk of progression from clinically isolated syndrome (CIS) to multiple sclerosis (MS) within one year, a new study shows. The study, “MRI in predicting conversion to multiple sclerosis within 1 year,” was published in the journal…

In women with relapsing-remitting multiple sclerosis (RRMS), there is a significant increase in brain lesion volume after pregnancy, but it is not accompanied by a loss of brain cells, a study suggests. Conducted by researchers at Harvard Medical School, the study, “Quantitative MRI analysis of cerebral lesions and…

Evaluating the local differences in iron accumulation in the deep gray matter of the brain using a special magnetic resonance imaging (MRI) technique, may help identify multiple sclerosis (MS) patients at greater risk for disease progression and disability, a study reports. The study “Brain Iron by Using Quantitative MRI…

Brain volume loss takes place at a faster rate in the first five years of multiple sclerosis than later in disease course, researchers report in a study that calls for scientists to “reconsider” — for this and related reasons — proposals to use volume loss as a measure of treatment efficacy…

An MRI technique known as magnetization transfer ratio (MTR) correlated closely with the progression of slowly evolving lesions (SELs) — a specific type of multiple sclerosis lesion — in patients with secondary progressive MS (SPMS). According to the researchers, monitoring changes in SELs — which indicate demyelination and loss of nerve fibers —…

Grey matter atrophy — its loss —  follows a sequential pattern that expands to involve more regions of the brain over time in all multiple sclerosis (MS) patients, regardless of their disease type, a new study reports. Atrophy progression is also similar between relapsing-remitting multiple sclerosis (RRMS) and primary-progressive multiple sclerosis (PPMS)…

Researchers Discover How Key Genetic Risk Factor for MS Operates A genetic link to MS is something that some scientists have suspected for years. Now, there’s new research that targets a variation of a specific gene as possibly being that link. Scientists have uncovered the molecular mechanism…
