- Diagnostic Value of PET Tracers in Differentiating Glioma Tumor Recurrence from Treatment-Related Changes: A Systematic Review and Meta-Analysis
This review of the literature found that amino acid-based tracers (such as 11C-MET and 18F-FDOPA) had the highest diagnostic value in identifying true progression of glioma and treatment-related change.
- Pituitary Gland Duplication Syndrome: An International Imaging Analysis
This study of 10 patients with DPG showed characteristic thickening of the ventral hypothalamic midline and duplication of the infundibulum, as well as associated craniofacial dysraphism, oropharyngeal mass (ie, teratoma), and vascular and vertebral anomalies. The repetitive spectrum of ventral abnormalities involving the skull base, pituitary region, corpus callosum, tuber cinereum, brainstem, cerebral arteries, and cervical spine suggests axial mesoderm duplication.
- Involvement Beyond Peripheral Nerves in Pure Neuritic Leprosy: An MR Imaging Study
Many patients with pure neuritic leprosy may have involvement of dorsal root ganglion, brachial plexus (thickening of trunks and cords), lumbar plexus, and spinal cord (intramedullary T2 hyperintensity). Patients may present with ganglionitis, plexitis, or myelitis.
- Laser Interstitial Thermal Therapy for Intra-Axial Brain Tumors: Everything the Neuroradiologist Should Know
This is a comprehensive overview of the indications, mechanisms of action, and radiologic assessments of laser interstitial thermal therapy (LITT), which delivers targeted cytotoxic thermal injury to intra-axial pathologies.
- Clinical Improvement after Shunt Surgery in Patients with Idiopathic Normal Pressure Hydrocephalus Can Be Quantified by Diffusion Tensor Imaging
This study investigated DTI parameter alterations in pre- and postshunt implantation in patients with iNPH and the relationship between DTI parameters and clinical improvement. Cognitive domain improvement after surgery correlated with preoperative DTI values of cingulate gyrus, uncinate fasciculus, superior longitudinal fasciculus, or corpus callosum, which are regions involved in memory and psychomotor speed processes.
