How to reliably evaluate middle ear diseases? Comparison of different methods of post-processing based on multislice computed tomography examination

Abstract

MPR reconstructions were most useful in the assessment of skull base trauma, skull base tumours and in cases of chronic middle ear inflammation. Highly vascularized tumours, disruption of ossicular chain and stapes prosthesis were best evaluated on 3-D reconstructions. Axial images proved to be the best for otosclerosis interpretation.

Quality assessment of 3D-CTVR, MPR and section plane techniques in ossicular chain reconstruction in middle ear cholesteatoma

“…In recent years, the more popular reconstruction techniques have included MPR, CTVR and endoscopy (CTVE) [5]. In fact, it is common nowadays to combine these various techniques in the diagnosis of ossicular lesions [3]. CTVE imaging, which is based on shaded-surface displays (SSD-based CTVE), has been discussed by many authors [4][5][6].…”

“…Another important method, the multi-planar reconstruction (MPR) technique, can even project multiple section planes of ossicles onto the same plane. Several authors have reported and discussed the advantages and limitations of these two protocols in their literature [1][2][3]. In our study, both the CTVR and MPR techniques, in conjunction with conventional axial and coronal section plane, were used to show up the fine structures of the ossicular chain.…”

Ką Turėtume Žinoti Apie Medicininę Apšvitą?

“…Šiuolaikinė programinė įranga suteikia galimybes atkurti kokybiškus diagnostinius vaizdus, kurie gaunami skenuojant sumažintos dozės protokolais [53]. Taip pat leidžia iš naujo arba retrospektyviai apdoroti turimus duomenis, atkuriant vaizdus nestandartinėse plokštumose ar sukuriant lenktas daugiaplokštumines rekonstrukcijas, pvz., vertinant kraujagyslių pakitimus, sudėtingas vidinės ausies kaulines struktūras [63][64][65]. Tai gali padėti išvengti intervencinių angiografinių ir kitų sudėtingų tyrimų [66].…”

Traumatology of the ear and temporal bone

“…Die Bildgebung mittels der in den vergangenen Jahren an Präzision weiterentwickelten Computertomographie (CT) mit 3-D-Rekonstruktion kann zur weiteren Abklärung bei Mittelohrverletzungen diskutiert werden [27]. Als Diagnostik und gleichzeitige Therapie der Wahl wird jedoch weiterhin die 7 Tympanoskopie und Wiederherstellung der Schallübertragung nach den tympanoplastischen Prinzipien etwa 3 bis 6 Monate nach stattgehabtem Trauma angesehen.…”
