Abstract

Background: Purpose of this study was to compare image quality of the skull base in standard 20s protocol flat panel computed tomography (FPCT) with the new time and dose improved 10s protocol as well as with 128 slice multidetector computed tomography (MDCT).

Methods: 10 whole skull preparations were scanned with either 128 slice MDCT(SOMATOM Definition AS+, Siemens, Erlangen) or FPCT (AXIOM-Artis, Siemens, Erlangen) using 10s or 20s protocol.

Results: FPCT provides significantly better image quality and improved delimitation of clinically relevant structures in the anterior, temporal and posterior skull base compared to 128 slice MDCT. The 20s FPCT protocol yielded best delimitability of evaluated skull base structures. However, the shorter, dose saving 10s FPCT protocol was still significantly superior to 128 slice MDCT regarding delimitability of skull base structures and additionally showed no significant inferiority compared with the 20s FPCT protocol.

Conclusions: The 10s FPCT protocol yields a significantly better image quality at a comparable radiation dose exposure in imaging skull base structures compared to MDCT.

平板CT与多探头CT在颅底成像中:图像质量有差异吗?

背景:本研究的目的是比较标准20s方案平板计算机断层扫描(FPCT)与新的时间和剂量改进10s方案以及128层多探测器计算机断层扫描(MDCT)颅底图像质量。方法:采用128层MDCT(SOMATOM Definition AS+， Siemens, Erlangen)或FPCT (AXIOM-Artis, Siemens, Erlangen)，采用10s或20s协议扫描10个全颅骨标本。结果:与128层MDCT相比，FPCT提供了更好的图像质量，改善了对前、颞、后颅底临床相关结构的划分。20年代FPCT方案获得了评估的颅底结构的最佳划界性。然而，较短且节省剂量的10s FPCT方案在颅底结构的可划分性方面仍明显优于128层MDCT，并且与20s FPCT方案相比没有明显的不足。结论:与MDCT相比，10s FPCT方案在相当辐射剂量下对颅底结构成像的图像质量明显更好。试验注册号:371/2017BO2。

期刊介绍： Head & Face Medicine is a multidisciplinary open access journal that publishes basic and clinical research concerning all aspects of cranial, facial and oral conditions. The journal covers all aspects of cranial, facial and oral diseases and their management. It has been designed as a multidisciplinary journal for clinicians and researchers involved in the diagnostic and therapeutic aspects of diseases which affect the human head and face. The journal is wide-ranging, covering the development, aetiology, epidemiology and therapy of head and face diseases to the basic science that underlies these diseases. Management of head and face diseases includes all aspects of surgical and non-surgical treatments including psychopharmacological therapies.
