Summary
Initial MRI findings in acute invasive fungal rhinosinusitis (AIFRS) can predict visual and mortality outcomes. Orbital apex or cerebral artery involvement indicates poor vision, while facial soft tissue or intracranial spread increases mortality risk.
Area of Science:
- Radiology
- Ophthalmology
- Infectious Diseases
Background:
- Acute invasive fungal rhinosinusitis (AIFRS) is a severe infection with significant morbidity and mortality.
- Early identification of prognostic factors is crucial for timely intervention and improved patient outcomes.
Purpose of the Study:
- To determine if initial, preintervention magnetic resonance imaging (MRI) findings can predict visual and mortality outcomes in patients with AIFRS.
Main Methods:
- Retrospective cohort study of 78 patients with confirmed AIFRS.
- Analysis of MRI scans and clinical records using modified Poisson regression and Cox proportional hazards models.
- Evaluation of radiologic characteristics for association with blindness and mortality.
Main Results:
- Orbital apex or cerebral artery involvement on initial MRI was associated with poor visual acuity (RR 2.0 and 1.8, respectively).
- Facial soft tissue, nasolacrimal drainage apparatus, or intracranial involvement correlated with increased mortality (HR 4.9, 5.0, and 3.5, respectively).
- Orbital soft tissue involvement was linked to decreased mortality (HR 0.3).
Conclusions:
- Initial MRI findings are prognostic for visual and mortality outcomes in AIFRS.
- Orbital apex and cerebral artery involvement predict poor visual outcomes.
- Facial soft tissue, nasolacrimal drainage, and intracranial spread indicate higher mortality risk, while orbital soft tissue involvement suggests a better prognosis.

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Radiological Investigation II: MRI and Ventilation Perfusion Scan
216
Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
