Gliomas and Glioblastomas represent a significant portion of central nervous system (CNS) tumors associated with high mortality rates and variable prognosis. In 2021, the World Health Organization (WHO) updated its Glioma classification criteria, most notably incorporating molecular markers including CDKN2A/B homozygous deletion, TERT promoter mutation, EGFR amplification, + 7/-10 chromosome copy number changes, and others into the grading and classification of adult and pediatric Gliomas. The inclusion of these markers and the corresponding introduction of new Glioma subtypes has allowed for more specific tailoring of clinical interventions and has inspired a new wave of Radiogenomic studies seeking to leverage medical imaging information to explore the diagnostic and prognostic implications of these new biomarkers.

Article Synopsis
  • Angioinvasive fungal sinusitis (AIFS) is a serious and rapidly worsening infection that requires early diagnosis and intervention to improve outcomes; however, diagnosing it can be difficult.
  • The study reviews important radiographic features that help identify AIFS, particularly in its early stages, and emphasizes the role of ophthalmologists in recognizing signs and escalating care to prevent complications.
  • Key radiographic indicators of AIFS include "black turbinate and maxillary sign," periantral changes, tissue invasion without bone erosion, and specific MRI findings; an algorithm for diagnosis and surgical exploration is proposed for at-risk patients.

Objective: Determine the utility of ZTE as an adjunct to routine MR for assessing degenerative disease in the cervical spine.

Methods: Retrospective study on 42 patients with cervical MR performed with ZTE from 1/1/2022 to 4/30/22. Fellowship trained radiologists evaluated each cervical disc level for neural foraminal (NF) narrowing, canal stenosis (CS), facet arthritis (FA), and presence of ossification of the posterior longitudinal ligament (OPLL).

Neuroimaging of certain pathologies requires both multi-parametric qualitative and quantitative imaging. The role of the quantitative MRI (qMRI) is well accepted but suffers from long acquisition times leading to patient discomfort, especially in geriatric and pediatric patients. Previous studies show that synthetic MRI can be used in order to reduce the scan time and provide qMRI as well as multi-contrast data.
