Highly-accelerated volumetric brain examination using optimized wave-CAIPI encoding.

Background: Rapid volumetric imaging protocols could better utilize limited scanner resources.

Purpose: To develop and validate an optimized 6-minute high-resolution volumetric brain MRI examination using Wave-CAIPI encoding.

Study Type: Prospective.

Therapeutic hypothermia for neonatal hypoxic-ischemic encephalopathy: magnetic resonance imaging findings and neurological outcomes in a Brazilian cohort.

Objective: To determine the neurodevelopment outcomes after therapeutic hypothermia for neonatal hypoxic-ischemic encephalopathy (HIE) and identify the neonatal magnetic resonance imaging (MRI) findings associated with neurological outcome in a middle-income country.

Study Design: All infants born after 35 completed weeks' gestation with signs of moderate to severe encephalopathy and evidence of perinatal asphyxia before 6 hours of life were submitted to whole-body hypothermia and were imaged at 18 ± 8.4 days of life (range 7-33 days) after birth.

Computed Tomography Evaluation of the Correspondence Between the Arcuate Eminence and the Superior Semicircular Canal.

Background: The arcuate eminence (AE) has been traditionally used in middle cranial fossa (MCF) surgery as a guide to accurate location of the superior semicircular canal (SSC) deep within the temporal bone. However, the anatomic relationship between the AE and SSC is controversial. We evaluated the anatomic coincidence between the AE and the SSC in the MCF surface.

Correction to: Correlation of CSF flow using phase-contrast MRI with ventriculomegaly and CSF opening pressure in mucopolysaccharidoses.

After publication of the article [1], it has been brought to our attention that the full funding acknowledgement is missing from the original article.

Correlation of CSF flow using phase-contrast MRI with ventriculomegaly and CSF opening pressure in mucopolysaccharidoses.

Background: Very little is known about the incidence and prevalence of hydrocephalus in patients with mucopolysaccharidoses (MPS). The biggest challenge is to distinguish communicating hydrocephalus from ventricular dilatation secondary to brain atrophy, because both conditions share common clinical and neuroradiological features. The main purpose of this study is to assess the relationship between ventriculomegaly, brain and cerebrospinal fluid (CSF) volumes, aqueductal and cervical CSF flows, and CSF opening pressure in MPS patients, and to provide potential biomarkers for abnormal CSF circulation.

Brain imaging and genetic risk in the pediatric population, part 2: congenital malformations of the central nervous system.

In this article, an update is presented of the correlation of imaging and genetic findings in congenital malformations of the central nervous system (CMCNS). A nonsystematic search of the PubMed/Medline database was performed. The congenital disorders were classified in 3 groups of malformation: ventral induction disorders, cortical malformations, and congenital malformations of the posterior fossa.

Brain imaging and genetic risk in the pediatric population, part 1: inherited metabolic diseases.

In this article, the genotype-MR phenotype correlation of the most common or clinically important inherited metabolic diseases (IMD) in the pediatric population is reviewed. A nonsystematic search of the PubMed/Medline database of relevant studies about "genotype-phenotype correlation" in IMD was performed. Some MR phenotypes related to specific gene mutations were found, such as bilateral hypertrophy of inferior olives in patients harboring POLG and SURF1 mutations, and central lesions in the cervical spinal cord in patients with nonketotic hyperglycinemia harboring GLRX5 gene mutation.
