A Novel Patient-Positioning Device for Dynamic CT Myelography [SPINE IMAGING AND SPINE IMAGE-GUIDED INTERVENTIONS]
We describe a novel patient-positioning device for dynamic CT myelography. Dynamic CT myelography requires angling the patient's spine to distribute dense contrast along the dependent thecal sac. The proposed device is constructed of a low-density reinforced polymer frame and can be raised or lowered to various heights with a hand-operated mechanism, allowing precise adjustment of the spinal angle and control of the contrast bolus, increasing the safety, reproducibility, and sensitivity of dynamic CT myelography.

Clinical Outcomes and Safety Comparison of Vertebroplasty, Balloon Kyphoplasty, and Vertebral Implant for Treatment of Vertebral Compression Fractures [SPINE IMAGING AND SPINE IMAGE-GUIDED INTERVENTIONS]
CONCLUSIONS:
The SpineJack vertebral implant showed equivalent pain improvement compared with vertebroplasty and kyphoplasty, but it had superior vertebral body height restoration and local kyphotic angle improvement. This study supports the SpineJack vertebral implant as a safe and effective alternative (adjunct) for vertebral augmentation, especially in patients with moderate-to-severe vertebral compression fractures for greater improvement in vertebral body height restoration.

Likelihood of Discovering a CSF Leak Based on Intracranial MRI Findings in Patients without a Spinal Longitudinal Extradural Collection: A New Probabilistic Scoring System [SPINE IMAGING AND SPINE IMAGE-GUIDED INTERVENTIONS]
CONCLUSIONS:
This study offers a new probabilistic scoring system for evaluating the likelihood of discovering a CSF leak on the basis of intracranial MR imaging findings, though the new system is not superior to that of the Dobrocky method for predicting the presence of CSF leaks.

Factors Predictive of Treatment Success in CT-Guided Fibrin Occlusion of CSF-Venous Fistulas: A Multicenter Retrospective Cross-Sectional Study [SPINE IMAGING AND SPINE IMAGE-GUIDED INTERVENTIONS]
CONCLUSIONS:
Fibrin occlusion performed across various institutions shows cure when associated with injectate spread matching the CVF drainage pattern and shorter pretreatment symptom duration, emphasizing the importance of accurate injectate placement and early intervention.

Fetal MR Imaging Anatomy of the Transverse Temporal Gyrus (Heschl Gyrus) [PEDIATRIC NEUROIMAGING]
CONCLUSIONS:
The Heschl gyrus appears on MR imaging at 24–25 weeks' gestational age, paralleling the functional activation of the auditory system. We propose the Heschl gyrus as an early additional MR imaging marker of fetal brain development. (Source: American Journal of Neuroradiology)

The Influence of Nonaerated Paranasal Sinuses on DTI Parameters of the Brain in 6- to 9-Year-Old Children [PEDIATRIC NEUROIMAGING]
CONCLUSIONS:
Nonaeration of the paranasal sinuses is a common incidental finding on pediatric MR imaging brain scans. The amount of air in the paranasal sinuses can influence fractional anisotropy and, to a lesser degree, mean diffusivity values of WM tracts and should be considered in DTI studies in pediatric populations.

MR Imaging Appearance of Ruptured Rathke Cleft Cyst and Associated Bone Marrow Enhancement [HEAD AND NECK IMAGING]

Prevalence of Cochlear-Facial and Other Non-Superior Semicircular Canal Third Window Dehiscence on High-Resolution Temporal Bone CT [HEAD AND NECK IMAGING]
CONCLUSIONS:
Sixty-four-channel CT with multioblique reformatting is sensitive and specific for identifying cochlear-facial dehiscence, with rates similar to those in postmortem series. Jugular bulb–vestibular aqueduct dehiscence is a common incidental finding and is unlikely to produce third window physiology. Other non-superior semicircular canal third window dehiscences are rare in asymptomatic patients. (Source: American Journal of Neuroradiology)

Specificity of Quantitative Functional Brain Mapping with Arterial Spin-Labeling for Preoperative Assessment [NEUROIMAGING PHYSICS/FUNCTIONAL NEUROIMAGING/CT AND MRI TECHNOLOGY]
CONCLUSIONS:
Our results confirm the specificity of functional ASL in targeting the regional neuronal excitability. Functional ASL could be considered as a valid supplementary technique to BOLD imaging for presurgical mapping when spatial accuracy is crucial for delineating eloquent cortex.

Blunt Cerebrovascular Injury: Are We Overscreening Low-Mechanism Trauma? [EMERGENCY NEURORADIOLOGY]
CONCLUSIONS:
We advocate reservation of blunt cerebrovascular injury screening in low-mechanism trauma for patients meeting the expanded Denver criteria. Further research is needed to determine the behavior of indeterminate cases and to establish criteria for separating true-positive from false-positive findings.

4D-DSA for Assessment of the Angioarchitecture and Grading of Cranial Dural AVF [NEUROINTERVENTION]
CONCLUSIONS:
Detailed analysis of dural AVFs according to the standardized display of 4D-DSA volumes was feasible and helpful in understanding the angioarchitecture in selected cases. Further improvement and validation of the 4D software should solidify the complementary role of 4D-DSA to conventional 2D-DSA series. (Source: American Journal of Neuroradiology)

Considering Psychological and Cognitive Factors in Interventional Neuroradiology: A Systematic Literature Review [NEUROINTERVENTION]
CONCLUSIONS:
Our review highlights the need to include cognitive and psychological assessments in clinical practice in case patients eligible for interventional neuroradiology procedures. In the future, much more research of and attention to cognitive and psychologic aspects of neurovascular disease is needed. Systematic incorporation of strategies and tools to access and address pre, peri-, and postprocedural psychological and cognitive components could have major benefits in patient satisfaction, recovery, and the success of endovascular practice.

Impact of Balloon Guide Catheters in Elderly Patients Treated with Mechanical Thrombectomy: Insights from the ROSSETTI Registry [NEUROINTERVENTION]
CONCLUSIONS:
In our study, balloon guide catheter use during endovascular treatment of anterior circulation large-vessel occlusion in elderly patients did not predict the first-pass effect, near-complete final recanalization, or functional independence at 3 months. Further studies, including randomized clinical trials, are needed to confirm these results. (Source: American Journal of Neuroradiology)

Radiogenomics Provides Insights into Gliomas Demonstrating Single-Arm 1p or 19q Deletion [BRAIN TUMOR IMAGING]
CONCLUSIONS:
IDH-mutant gliomas with single-arm 1p or 19q deletion have MR imaging appearance and survival that are similar to those of astrocytomas without 1p or 19q deletion and significantly different from those of 1p/19q-codeleted oligodendrogliomas. (Source: American Journal of Neuroradiology)
