Clinical 1H MRS in childhood neurometabolic diseases —part 1: technique and age-related normal spectra
AbstractDespite its vigorous ability to detect and measure metabolic disturbances,1H MRS remains underutilized in clinical practice. MRS increases diagnostic yield and provides therapeutic measures. Because many inborn metabolic errors are now treatable, early diagnosis is crucial to prevent or curb permanent brain injury. Therefore, patients with known or suspected inborn metabolic errors stand to benefit from the addition of MRS. With education and practice, all neuroradiologists can perform and interpret MRS notwithstanding their training and prior experience. In this two-part review, we cover the requisite concepts for...

Association between carotid artery dissection and vascular tortuosity: a case –control study
ConclusionVT appears to be associated with an increased risk of dissection for the carotid district but not for the vertebral one. The different structure, embryogenesis, and pathophysiology of dissection between the two districts could explain this finding. VTI threshold as carotid artery dissection predictor deserves confirmation in larger studies. (Source: Neuroradiology)

Matrix metalloproteinase-2 and matrix metalloproteinase-9 serum levels in patients with vertebrobasilar dolichoectasia with and without stroke: case –control study
ConclusionThis study found that high serum levels of MMP-9 are associated with VBD independently of stroke and correlated with the degree of VBD. (Source: Neuroradiology)

The diagnostic accuracy of MRI in determining the relations between paraclinoid aneurysms and the cavernous sinus
Conclusion3D fast spin-echo MRI sequence is a reliable and useful technique for determining the location of paraclinoid aneurysms in relation to the cavernous sinus, particularly for patients with no history of SAH. (Source: Neuroradiology)

Intraoperative motor-evoked potential monitoring during coil embolization for anterior choroidal artery aneurysms
ConclusionIntraoperative MEP monitoring during endovascular coiling for AChA aneurysms may be feasible. AChA blood flow detected by angiography does not always reflect MEP status. (Source: Neuroradiology)

The potential role of diffusion weighted imaging in the diagnosis of early carotid and vertebral artery dissection
ConclusionDWI is a highly sensitive and valuable pulse sequence for the detection of dissected cervical arteries even in the first hours after symptom onset. In contrast to CTA and MRA, DWI can be a potential tool for a reliable measurement of the dissection length. (Source: Neuroradiology)

Clinical 1H MRS in childhood neurometabolic diseases — part 2: MRS signatures
AbstractProton MRS of the brain provides the ability to gather direct information regarding the metabolic status of the brain at the time of MRI. Although selective vulnerability of brain tissue may yield distinct imaging patterns in neurometabolic disorders, it is not uncommon for the brain MRI to be normal, nonspecific, or show ambiguous abnormalities among several possible diagnoses, metabolic, or otherwise. This review highlights childhood neurometabolic diseases in which1H MRS may show diagnostic or suggestive metabolic profiles without complicated acquisition or postprocessing techniques.

3.0 Tesla normative diffusivity in 3rd trimester fetal brain
ConclusionRegional brain ADC values in 3.0  T scanners are comparable with previously reported values in 1.5 T scanners, with similar changes over gestational age. Using 3.0 T scanners is increasing worldwide. For fetal imaging, establishing normal ADC values is critical as DWI enables a sensitive and quantitative technique to evaluate no rmal and abnormal brain development. (Source: Neuroradiology)

Predictive value of DWI posterior-circulation lesion volume for 90-day clinical outcome after endovascular treatment of acute basilar artery occlusion: a retrospective single-center study
ConclusionsPre-treatment PCLV was an independent predictor of 90-day outcomes in ABAO. A PCLV  ≤ 8.7 and ≥ 9.1 ml may identify patients with a higher possibility to achieve independence and a higher risk of death at 90 days, respectively. (Source: Neuroradiology)

Guidelines for magnetic resonance imaging in pediatric head and neck pathologies: a multicentre international consensus paper
AbstractThe use of standardized imaging protocols is paramount in order to facilitate comparable, reproducible images and, consequently, to optimize patient care. Standardized MR protocols are lacking when studying head and neck pathologies in the pediatric population. We propose an international, multicenter consensus paper focused on providing the best combination of acquisition time/technical requirements and image quality. Distinct protocols for different regions of the head and neck and, in some cases, for specific pathologies or clinical indications are recommended. This white paper is endorsed by several internation...

Contrast-induced encephalopathy —neuroimaging findings and clinical relevance
AbstractContrast-induced encephalopathy (CIE) is a rare encephalopathic condition after the administration of a contrast agent. The diagnosis of CIE is challenging because of the heterogeneity and non-specificity of the clinical presentation. The clinical course is usually favorable with full recovery within 48 –72 h in most patients, although comorbidity is of relevance and contributes to the clinical outcome. It is expected that the incidence of CIE is currently increasing, due to an increase in endovascular and diagnostic imaging procedures using iodinated contrast. It is important to include CIE in the differential ...
