Percutaneous Thermal Ablation of Spinal Metastases: Recent Advances and Review.

Objective: The purpose of this study was to review the available armamentarium and most recent advances in minimally invasive, image-guided percutaneous thermal ablation for treatment of spinal metastases.

Conclusion: Minimally invasive percutaneous spine thermal ablation technologies have proved safe and effective in management of selected patients with spinal metastases. Special attention to procedure techniques including choice of ablation modality, thermoprotection, adequacy of treatment, and postablation imaging is essential for improved patient outcomes.

Multisystem Imaging Findings of Cystic Fibrosis in Adults: Recognizing Typical and Atypical Patterns of Disease.

Objective: There is an expanding and increasingly heterogeneous population of adult patients with cystic fibrosis (CF). Although CF is usually diagnosed in children with progressive multisystem involvement, up to 7% of CF cases are currently diagnosed de novo in adults with subtle manifestations distinct from the typical features of classic CF. The purpose of this article is to present the wide spectrum of CF in adults, including both classic and nonclassic variants, with an emphasis on the nonclassic imaging findings.

Computed Tomography and Magnetic Resonance Findings of Fat-Poor Angiomyolipomas.

Introduction: Approximately 5% of angiomyolipomas (AMLs) are classified as "fat poor" due to lack of visually detectable fat on imaging, making them difficult to distinguish from renal cell carcinoma. Recent investigations have proposed CT and MR imaging features suggestive of fat-poor AML (fp-AML). Herein, we determined the frequency of these features in a cohort of fp-AMLs by retrospective review of preoperative imaging.

The impact of prenatal and neonatal infection on neurodevelopmental outcomes in very preterm infants.

Objective: Determine the association of prenatal and neonatal infections with neurodevelopmental outcomes in very preterm infants.

Study Design: Secondary retrospective analysis of 155 very preterm infants at a single tertiary referral center. General linear or logistic regression models were used to evaluate the association with hospital factors; brain injury, growth and development; and neurobehavioral outcome.

Diffusion tractography and neuromotor outcome in very preterm children with white matter abnormalities.

Background: Moderate-to-severe white matter abnormality (WMA) in the newborn has been shown to produce persistent disruptions in cerebral connectivity but does not universally result in neurodevelopmental disability in very preterm (VPT) children. The aims of this hypothesis-driven study were to apply diffusion imaging to: (i) examine whether bilateral WMA detected in VPT children in the newborn period can predict microstructural organization at the age of 7 y and (ii) compare corticospinal tract and corpus callosum (CC) measures in VPT children at the age of 7 y with neonatal WMA with normal vs. impaired motor functioning.
