Short-term follow-up pilot study of sole middle meningeal artery embolization for chronic subdural hematoma: influence of internal architecture on the radiological outcomes
ConclusionSeparated CSDH is a poor prognostic type in achieving radiological endpoint and a slower rate of volume reduction. While, homogeneous and laminar types reached the endpoint faster than separated and trabecular types on short-term follow-up. (Source: Neuroradiology)

MRI for collateral assessment pre-thrombectomy and association with outcome: a systematic review and meta-analysis
ConclusionIn stroke patients treated with thrombectomy, good pre-treatment collaterals assessed using MRI are associated with double the rate of functional independence. However, we found evidence that relevant MR methods are heterogenous and under-reported. Greater standardization and clinical validation of MRI for collateral evaluation pre-thrombectomy are required. (Source: Neuroradiology)

Impact on etiology diagnosis by high-resolution vessel wall imaging in young adults with ischemic stroke or transient ischemic attack
ConclusionsHRVWI had a substantial impact on etiologic classification in young adults with ischemic stroke or TIA, particularly for those primarily classified as having SAO or SUE. This impact of HRVWI will be beneficial for therapeutic decision-making. (Source: Neuroradiology)

Artificial intelligence tools in clinical neuroradiology: essential medico-legal aspects
AbstractCommercial software based on artificial intelligence (AI) is entering clinical practice in neuroradiology. Consequently, medico-legal aspects of using Software as a Medical Device (SaMD) become increasingly important. These medico-legal issues warrant an interdisciplinary approach and may affect the way we work in daily practice. In this article, we seek to address three major topics: medical malpractice liability, regulation of AI-based medical devices, and privacy protection in shared medical imaging data, thereby focusing on the legal frameworks of the European Union and the USA. As many of the presented concept...

Predictive value of preoperative magnetic resonance imaging structural and diffusion indices for the results of trigeminal neuralgia microvascular decompression surgery
ConclusionNVC and RD of SpTV are independent risk factors for poor results after MVD surgery, and combining the NVC and RD might achieve relatively high predictive value for poor results. (Source: Neuroradiology)

Oligodendrogliomas tend to infiltrate the frontal aslant tract, whereas astrocytomas tend to displace it
ConclusionHigh sensitivity but low specificity for displacement in astrocytomas demonstrates that in the case of an astrocytoma, the tract is most likely displaced, but that displacement in itself is not necessarily predictive for astrocytomas, as oligodendrogliomas may both infiltrate and displace a tract. Overall, these results demonstrate that oligodendrogliomas tend to infiltrate the nearby subcortical tract, whereas astrocytomas only tend to displace it. (Source: Neuroradiology)

Increased pituitary volumes in patients with Sanfilippo syndrome (mucopolysaccharidosis type 3, MPS III)
ConclusionIn our cohort of patients with Sanfilippo syndrome, whole, anterior, and posterior pituitary volumes and degree of convexity along the upper pituitary border were all significantly greater than controls. The cause of these morphological changes is unclear, as is clinical correlation of the findings. (Source: Neuroradiology)

Congenital melanocytic naevus syndrome and Dandy-Walker malformation — a mistaken association: case report and literature review
AbstractCongenital melanocytic naevus (CMN) syndrome, previously termed neurocutaneous melanosis, is a rare disease caused by postzygotic mosaic mutations occurring during embryogenesis in precursors of melanocytes. The severity of neurological manifestations in CMN patients is related to central nervous system abnormalities found at magnetic resonance imaging. The association between CMN and Dandy –Walker malformation (DWM) has been described in the literature, but recent advances in imaging and genetics lead to diagnostic criteria revision. In this paper, we aim to re-evaluate the proposed association by reviewing the ...

Central tegmental tract hyperintensity: follow-up outcomes from a single-center study
ConclusionCTTH is a radiological finding commonly seen in early childhood but its clinical relevance has not been fully elucidated. While CTTH may be a transient phenomenon representing the maturation process, it may also be associated with a number of clinical conditions. Using a large patient series and follow-up MRI scans, our study shed light on the possible etiological factors of CTTH and its evolution over time. (Source: Neuroradiology)

Postsurgical dural supply to the spinal cord arteriovenous malformation in spinal arteriovenous metameric syndrome
AbstractDural supply from the external carotid system in cerebral arteriovenous malformations (AVMs) is well known, but actual angiographic evidence of dural supply to spinal cord AVMs (SCAVMs) has not been reported. Here, we report a case of dural supply to the conus SCAVM in the spinal arteriovenous metameric syndrome segment 25 –30. Thirteen years after spinal surgery (T12–L2 laminoplasty), spinal angiography showed multiple dural supplies from the dorsal somatic branches, prelaminar arteries, and radiculomeningeal arteries to the SCAVM at the level of the previous spinal surgery. To the best of our knowledge, this ...

The proximity between styloid process and internal carotid artery as a possible risk factor for dissection: a case –control study
ConclusionA short SP-ICA distance appears to be a risk factor for CAD as it likely induces a continuous microtraumatism of the vessel wall during normal head and neck movements. (Source: Neuroradiology)

The presence of pachymeningeal hyperintensity on non-contrast flair imaging in patients with spontaneous intracranial hypotension
ConclusionWhere present, diffuse pachymeningeal hyperintensity can be accurately identified on a non-contrast FLAIR sequence in patients with spontaneous intracranial hypotension. This potentially obviates the need for gadolinium base contrast agents in the work-up of these patients. (Source: Neuroradiology)

Detection of cerebral cortical vein thrombosis with high-resolution susceptibility weighted imaging —  A comparison with MR venography and standard MR sequences
ConclusionSusceptibility weighted imaging demonstrates the best sensitivity and accuracy among  standard MR sequences including MR venography for the detection of early stage cortical vein clots. However, it needs to be interpreted in combination with other MR sequences for the most accurate evaluation of cortical vein clots. (Source: Neuroradiology)
