The unique biomechanical, hemodynamical, and functional characteristics of the developing brain and the age‐dependent variance in trauma mechanisms result in a wide range of age specific traumas and patterns of brain injuries. Detailed knowledge of the main primary and secondary pediatric injuries, which enhance sensitivity and specificity of diagnosis, will guide therapy and may give important information about the prognosis. In recent years, anatomical but also functional imaging methods have revolutionized neuroimaging of pediatric TBI. The purpose of this article is (1) to comprehensively review frequent primary and secondary brain injuries and (2) to give a short overview of two special typ...

One of the most frequent CNS abnormalities on imaging is the affection of the white matter (WMLs) for which the term, leukoencephalopathies in mitochondrial disorders (LEM), is proposed. The morphology of LEM on imaging is quite variable even within the same type of MID and the same family. LEM can be a subtle or prominent feature on imaging and may go along with or without clinical neurologic or neuropsychological manifestations. WMLs are most likely due to the underlying metabolic defect of the respiratory chain or concomitant oxidative stress, resulting in neuronal death and replacement of neurons by glial cells. WMLs in MIDs frequently give rise to misinterpretation,...

Nonhemorrhagic stroke has not been reported previously in any adult with IAA. We, herein, describe a formerly asymptomatic 52‐year‐old male presenting with recurrent vertebrobasilar circulation ischemic strokes resulting from accelerated atherosclerotic arteriopathy secondary to IAA associated upper body hypertension. Surgical correction of IAA led to treatment of hypertension and cessation of ischemic attacks together with regression of collateral arterial networks as shown by computer tomography angiography.J Neuroimaging 2012;XX:1–3.

Patients being evaluated for reasons less closely correlated with atherosclerotic disease, such as arteriovenous malformation (AVM) or hemorrhage showed a lower prevalence of VA stenosis (brain aneurysm or AVM 5/121, 4.1%, brain hemorrhage 5/153, 3.3%). Routine clinical MRA significantly overestimates VOS prevalence, and findings suggest that CTA underestimates the degree and prevalence of VOS.J Neuroimaging 2012;XX:1–8.

In this context, magnetic resonance neurography (MRN) offers high‐resolution imaging of the tibial nerve (TN), its branches and the adjacent soft tissues, and provides an objective assessment of the neuromuscular anatomy, abnormality, and the surrounding pathology. This review describes the pathologies affecting the TN and illustrates their respective 3 Tesla (T) MRN appearances with relevant case examples. J Neuroimaging 2012;XX:1–15.

CT angiography (CTA) reveals the cranio‐cervical vessel and the occlusion site. Furthermore, the source image (SI) of the CTA (CTA‐SI) reflects cerebral blood volume and can detect the infarct core as hypoattenuated areas with higher sensitivity than ischemic changes on NCCT. However, it was recently reported that the CTA‐SI using fast acquisition protocol significantly overestimated the infarct core mostly on the basis of the poor collaterals. On the other hand, CTA‐SI using standardized protocol was reported to be good predictor for final infarct extension. Imaging used in the setting of acute stroke should a...

The biomechanical properties of the child's brain and skull, the size of the child, the age‐specific activity pattern, and higher degree of brain plasticity result in a unique distribution, degree, and quality of TBI compared to adult TBI. A detailed knowledge about the various types of primary and secondary pediatric head injuries is essential to better identify and understand pediatric TBI. The goals of this review article are (1) to discuss the unique epidemiology, mechanisms, and characteristics of TBI in children, and (2) to review the anatomical and functional imaging techniques that can be used to study common and rare pediatric traumatic brain injuries and their complicat...

The cerebellar activity is associated exclusively with the postponement of action until the right moment, whereas both the cerebellum and striatum are needed for successful adaptation of motor actions from one trial to the next. We found a general ‘‘hypoactivation’’ of basal ganglia and cerebellum in early stage PD relative to HC, indicating that even in early stages of the PD there could be functional perturbations in the motor system beyond striatum.J Neuroimaging 2011;XX:1–9.

The patient had a history of hypertension, hypercholesterolemia, cigarette smoking, and a postoperative abdominal aortic aneurysm. He presented with a sudden onset of weakness of the left arm and leg. Magnetic resonance imaging revealed old and fresh infarction in the right cerebral hemisphere. Carotid duplex ultrasonography showed a dolichoectatic right common carotid artery with a maximum diameter of 39 mm with thick plaque and strong spontaneous echo contrast. The flow velocity was considerably reduced, which caused thrombus formation, and strong antithrombotic therapy was required.

Among our cohort, 23% of patients had no evidence of vascular injury or hemorrhage during the initial transsphenoidal operation, and presented at an average of 83 days after surgery. The average time to diagnosis for patients with intraoperative bleeding was 64 days after surgery. Epistaxis was the most common initial presenting symptom, seen in 41% of patients, and traditional angiography was employed in every case to make the diagnosis of pseudoaneurysm. Though complete occlusion of the ICA was ultimately required in 41% of patients, the remainder were treated with a variety of modalities.

A 46‐year‐old man underwent an urgent right CAS under proximal flow reversal for embolic protection for a hemodynamically significant symptomatic near‐occlusion of the internal carotid artery. IVUS was used to evaluate immediate poststenting results and identify potential thromboembolic material extruding through the tines of the stent. An intraluminal thrombus was identified with IVUS after the stent was deployed. This led to the use of a second stent in an attempt to trap the thrombus. Ultimately, the thrombus was removed with the use of a multipurpose‐angled catheter under IVUS guidance. The artery reconstituted almost completely after stent placement, and the patient's condition improved significantly. IVUS iden...

The goal of the multicenter Grand Ouest Glioblastoma Project (GOGP) was to correlate MRI quantitative parameters with biological markers extracted from image‐guided biopsies. Therefore, it was essential to ensure spatial coherence of the parameters as well as the signal intensity and homogeneity. The project included the same MRI protocol implemented on six devices from different manufacturers. The key point was the initial acceptance of the imaging devices and protocol sequences. For this purpose, and to allow comparison of quantitative patient data, we propose a specific method for quality assessment. A common ...

Open microvascular decompression alleviated the patient's long‐standing suboccipital and posterior cervical neck pain. An embryologic review of the vertebral and lateral spinal artery systems reveals possible developmental explanations for this variant. Intradural course of the vertebral artery at C2 is one of the few symptomatic developmental vertebral artery anomalies. Recognition of this condition is important because surgical intervention can alleviate a...

In some of the metabolic disorders, long‐term dietary or medical treatment options are available and an early diagnosis helps limit the amount of brain damage. Neuroimaging also provides a baseline in evaluation of the efficacy of treatment.

In acquisition of neuroimaging scans, the lack of perfect alignment of a patient's head makes it challenging to evaluate brain images. By deploying a shape‐based criterion, the symmetry plane is defined as a plane that best matches external surface points on one side of the head, with their counterparts on the other side. In our method, the head volume is represented as a re‐parameterized surface point cloud, where each location is parameterized by its elevation (latitude), azimuth (longitude), and radius. The search for the best matching surfaces is implemented in a multi‐resolution paradigm, and the computation time is significantly decreased. The alg...

An embolic source in the setting of minimal stenosis at the carotid bifurcation has rarely been reported. The authors report a previously healthy 48‐year‐old woman, without any risk factors for cerebrovascular events, sustained multiple cerebral infarctions in the right anterior and middle cerebral artery territory. Repeated imaging of the heart and cerebral vessels missed a very small abnormality arising from the posterior wall of the internal carotid artery, until it was diagnosed by computed tomographic angiography. This is problematic because by North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria, minimal stenosis essentially excludes the carotid ...

The greater SMC activation using FTT task compared to the HS task was primarily due to an increase in activation in the post‐central sensory cortex. There was less lateralization, and therefore a greater degree of bilateral SMC activation, in the FTT task compared to the HS task. These results show the importance of optimization and fMRI task selection for presurgical SMC mapping.

Cerebral angiography revealed 2 AVF, a symptomatic PAVF located at the craniocervical junction and fed from the anterior spinal artery and incidental dural AVF (DAVF) originate from the left occipital and middle meningeal arteries. These fistulae were treated with different endovascular techniques, including Onyx and platinum coil embolization into the feeding arteries of the DAVF and PAVF, respectively.

Formation of these lesions after a penetrating missile wound is very unusual, and diagnosis can be difficult due to the presence of associated lesions. In this article, we report a case of a woman who developed a middle cerebral artery aneurysm after a gunshot wound, and discuss potential pitfalls found during diagnostic work‐up.

Both of these approaches have their unique strengths and weaknesses. The concept of chronological‐based thrombolysis is supported by several randomized clinical trials whereas imaging‐based thrombolysis has not been validated entirely by randomized trials. Therefore, careful evaluation of strategies using image‐based identification of patients who might benefit from thrombolysis is needed. Patients undergoing thrombolysis on delayed arrival appear to be the most logical group in whom image‐based strategies should be evaluated.
