A New Proposed Combined CT and MRI Staging System for Covid-19-Associated Rhino-Orbito-Cerebral Fungal Infection: A Multi-center Study with Pathological Correlation.

Rationale And Objectives: To propose a combined computed tomography (CT) and magnetic resonance imaging (MRI) based classification system in the management of COVID-19-associated rhino-orbito-cerebral (C-ROC) fungal infection and to assess the reliability of such proposed staging system.

Materials And Methods: This was a multi-center prospective study conducted on 122 adults with previously confirmed COVID-19 infection. CT and contrast-enhanced MRI (CE-MRI) were performed for all patients.

Aorta unfolding index as an indicator for coronary artery disease severity.

Background: Aortic unfolding index (AUI) is an independent predictor of cardiovascular events, yet there is scarcity in the literature on its association with the severity of coronary artery disease (CAD).

Purpose: To investigate the correlation between aortic unfolding and coronary artery disease severity score.

Material And Methods: The study included 115 patients with various degrees of CAD who underwent invasive coronary angiography and were retrospectively studied.
