This special collection sponsored by Bracco highlights the pivotal role of high-relaxivity GBCAs, showcasing their ability to provide superior contrast enhancement, reduce gadolinium exposure, and elevate diagnostic confidence across a spectrum of neurological conditions.

Check our Fellows’ Journal Club choice for the month: ‘Cracking the Code of Calcification: How Presence and Burden among Intracranial Arteries Influence Stroke Incidence and Recurrence’
This meta-analysis demonstrates a weak yet present association between intracranial arterial calcification and stroke events. However, given the high prevalence of calcification in the general population, its role for stroke prediction has limited evidence. Future studies may focus on specific arterial segments and emerging calcification patterns to improve predictive accuracy

‘Management Outcomes after Image-Guided Percutaneous Biopsy for Suspected Vertebral Osteomyelitis-Discitis’

This retrospective study of patients who underwent image-guided biopsy for suspected vertebral osteomyelitis-discitis aimed to assess how biopsy results impact clinical management.
It was found that biopsy results changed management in 36% of cases, mostly in culture-positive cases allowing for customizing antibiotic treatment. While antibiotic therapy at the time of biopsy did not impact yield, it was concluded that it may lead to less management change.

Check one of Editor’s choice for the month: ‘Comparing CT-Like Bone Images Based on Fast Field Echo Resembling a CT Using Restricted Echo Spacing (FRACTURE) MR with CT in Pediatric Congenital Vertebral Anomalies’

FRACTURE MR is reliable for bone imaging in pediatric complex spinal anomalies with substantial to perfect agreement between the 2 modalities. The bone signal is lower in children younger than 3 years due to a more cartilaginous skeleton. Despite some drawbacks of the sequences, it has the potential to complement conventional MR sequences in place of CT for bone assessment in pediatric complex spinal anomalies. This can reduce the radiation dose and an additional study in this group of pediatric patients who will be serially followed up with imaging during their management. We believe that FRACTURE MR still in its naïve form cannot replace CT, at least in trauma due to time constraints and postoperative studies due to susceptibility from metallic implants. Whether it holds potential in pediatric spine trauma or other vertebral pathologies needs to be evaluated by additional studies.
