REVIEW
Matthew K Schindler, Pascal Sati, Daniel S Reich
Ultrahigh-field (≥7 T) magnetic resonance (MR) imaging is being used at many leading academic medical centers to study neurologic disorders. The improved spatial resolution and anatomic detail are due to the increase in signal-to-noise and contrast-to-noise ratio at higher magnetic field strengths. Ultrahigh-field MR imaging improves multiple sclerosis (MS) lesion detection, with particular sensitivity to detect cortical lesions. The increase in magnetic susceptibility effects inherent to ultrahigh field can be used to detect pathologic features of MS lesions, including a central vein, potentially useful for diagnostic considerations, and heterogeneity among MS lesions, potentially useful in determining lesion outcomes...

Multiple sclerosis is a multifactorial disease with heterogeneous pathogenetic mechanisms, which deserve to be studied to evaluate new possible targets for treatments and improve patient management. MR spectroscopy and PET allow assessing in vivo the molecular and metabolic mechanisms underlying the pathogenesis of multiple sclerosis. This article focuses on the relationship between these imaging techniques and the biologic and chemical pathways leading to multiple sclerosis pathology and its clinical features...

REVIEW

Increased iron deposition in cerebral deep gray matter has been considered a global marker for neurodegeneration in multiple sclerosis (MS); it scales with disease duration and severity. Iron accumulation in white matter and MS lesions might be more directly related to disease activity and has been discussed as a contributor to the inflammatory and neurodegenerative cascade. New insights into iron and MS are expected from MR imaging. We discuss findings from MR iron mapping proposed. Because of the confounding magnetic properties of myelin, iron mapping in white matter remains an unresolved issue...

Due to its sensitivity in the detection of focal white matter (WM) lesions, MR imaging has become a paraclinical tool central to diagnosing multiple sclerosis (MS) and monitoring its evolution. Despite this, the correlation between patients' clinical status and conventional MR imaging measures is weak to moderate. Quantitative MR imaging-based techniques, such as magnetization transfer and diffusion tensor imaging, have a higher specificity toward the heterogeneous pathologic substrates of MS than MR imaging...

Several neuropathologic and imaging studies have consistently confirmed that multiple sclerosis affects both white (WM) and gray matter (GM) and that GM damage plays a key role in disability progression. However, differently from WM damage, the less inflammatory cell infiltration, the absence of significant blood-brain barrier damage, the low myelin density in upper cortical layers, as well as technical constraints, make the GM damage almost undetectable by means of conventional MR imaging.

There is evidence of a neurodegenerative process running in parallel with or as a consequence of the inflammatory phenomenon in multiple sclerosis (MS). MR imaging has been central in the generation of such knowledge and has played a pivotal role in investigating the neurodegenerative process. However, there is insufficient evidence supporting MR imaging-measured brain atrophy as a biomarker of the neurodegenerative component of MS in the daily care of patients with MS. This article discusses the prognostic value of brain volume measurements and their potential role in monitoring treatment response in patients with MS...

MR imaging is the most sensitive tool for identifying lesions in patients with multiple sclerosis (MS). MR imaging has also acquired an essential role in the detection of complications arising from these treatments and in the assessment and prediction of efficacy. In the future, other radiological measures that have shown prognostic value may be incorporated within the models for predicting treatment response. This article examines the role of MR imaging as a prognostic tool in patients with MS and the recommendations that have been proposed in recent years to monitor patients who are treated with disease-modifying drugs...

Remarkable advances in the understanding of the biology of multiple sclerosis have been achieved through the use of conventional and novel MR imaging techniques of the central nervous system. With improvements in access by patients and utilization of MR imaging technology in health care, an increasing number of unanticipated structural anomalies are being appreciated. In certain instances, white matter abnormalities within the brain and spinal cord are discovered in subjects with no prior history of neurologic symptoms supportive of inflammatory demyelinating events...

Neuromyelitis optica (NMO) is clinically characterized by severe optic neuritis and transverse myelitis, but recent studies with anti-aquaporin-4-antibody specific to NMO have revealed that the clinical spectrum is wider than previously thought. International consensus diagnostic criteria propose NMO spectrum disorders (NMOSD) as the term to define the entire spectrum including typical NMO, optic neuritis, acute myelitis, brain syndrome, and their combinations. NMOSD is now divided into anti-aquaporin-4-antibody-seropositive NMOSD and -seronegative NMOSD (or unknown serostatus)...

Multiple sclerosis (MS) is a disabling disease, with the first symptoms mostly appearing early in life. In addition to the clinical and laboratory findings, imaging has become increasingly important for diagnosis, prognosis, and monitoring. Because of its importance for these purposes, a high level of knowledge of imaging MS pathology and a standardization of the imaging acquisition, interpretation, and reporting is necessary. Here we will describe the MR imaging characteristics of MS pathology, the current imaging protocols, diagnostic criteria, and the differential diagnosis of MS...

Multiple sclerosis (MS) is a chronic autoimmune and degenerative disease of the central nervous system that affects young people. MS develops in genetically susceptible individuals exposed to different unknown triggering factors. Different phenotypes are described. About 15% of patients present with a primary progressive course and 85% with a relapsing-remitting course. An increasing number of disease-modifying treatments has emerged. Although encouraging, the number of drugs challenges the neurologist because each treatment has its own risk-benefit profile...

REVIEW

Masses in the sella and parasellar region comprise about 10% of all pediatric brain tumors but type and frequency differs from those in adults. Imaging is critical for diagnosis and characterization of these lesions. By assessing the site of origin, signal and contrast enhancement characteristics, and the presence or absence of characteristic patterns, differential diagnosis can narrow the possibilities. The clinical presentation is often characteristic for lesion type and should be considered. This article summarizes the characteristic imaging features of the most frequent pediatric tumors and tumor-mimicking lesions in children in this region...

A review of pediatric pineal region tumors is provided with emphasis on advanced imaging techniques. The 3 major categories of pineal region tumors include germ cell tumors, pineal parenchymal tumors, and tumors arising from adjacent structures such as tectal astrocytomas. The clinical presentation, biochemical markers, and imaging of these types of tumors are reviewed.

Brain tumors can develop in the prenatal and neonatal time periods. Neuroimaging studies are crucial for the early detection of prenatal and neonatal brain tumors. Imaging allows for characterization of morphology, as well as the detection of hydrocephalus, local invasion, and distant spread. The imaging features of the more common neonatal brain tumors, including teratomas, choroid plexus tumors, ATRTs, and neoplasm mimics are described.

REVIEW
Carlos Zamora, Thierry A G M Huisman, Izlem Izbudak
The breadth of tumors that can arise in the supratentorial brain in children is extensive. With the exception of those that result in seizures and the highly malignant histologies, supratentorial tumors may come to medical attention later compared with infratentorial tumors, as they are less commonly associated with ventricular obstruction. This article presents an overview of the neuroimaging characteristics of these entities, with particular attention to relevant features that may aid in narrowing the differential diagnosis, including correlation with demographics and clinical presentation...
