Aortitis: Hallazgos radiológicos en relación a sus diversas etiologías

Rev. argent. radiol; 84 (2), 2020
Resumen La inflamación de la aorta (aortitis) es una patología poco frecuente, con etiología infecciosa (pseudoaneurisma micótico, sífilis) y no infecciosa (arteritis, aortitis idiopática, espondilitis anquilosante, entre otras) de difícil diagnóstico clínico y variable pronóstico. Por esa razÃ...

In Vivo Computed Tomography Direct Volume Rendering of the Anterior Ethmoidal Artery: A Descriptive Anatomical Study

Abstract Introduction The clinical relevance of the anatomy and variations of the anterior ethmoidal artery (AEA) is outstanding, considering its role as a landmark in endoscopic surgery, its importance in the therapy of epistaxis, and the high risks related to iatrogenic injuries. Objective To provi...

The anatomic analysis of the vidian canal and the surrounding structures concerning vidian neurectomy using computed tomography scans

Abstract Introduction: The type of endoscopic approach chosen for vidian neurectomy can be specified by evaluating the vidian canal and the surrounding sphenoid sinus structures. Objective: The variations and morphometry of the vidian canal were investigated, focusing on the functional correlations bet...

Are computed tomography 3D measurements of the upper airways in mouth-breathing children in agreement with the ENT clinical diagnosis of obstruction?

Abstract Introduction: Imaging studies have hystorically been used to support the clinical otorhinolaryngological evaluation of the upper respiratory tract for the diagnosis of obstructive causes of oral breathing. Objective: The objective of this study was to compare 3D volumetric measurements of nasa...
