The diagnostic value of zero echo time magnetic resonance imaging for skull base bone invasion in nasopharyngeal carcinoma
鼻咽癌颅底骨侵犯的常规评估依赖CT,但CT的电离辐射存在潜在危害。零回波时间磁共振成像(zero echo time magnetic resonance imaging,ZTE-MRI)可在无辐射条件下获得高分辨率骨结构信息。本研究旨在系统评价ZTE-MRI对鼻咽癌颅底骨侵犯的诊断效能,并探讨其临床替代CT的可行性。
Owing to the reliance on computed tomography (CT) for evaluating skull-base bone invasion in nasopharyngeal carcinoma and the potential harm of ionizing radiation from CT
zero echo time magnetic resonance imaging (ZTE-MRI) offers high-resolution bone delineation without radiation exposure. Therefore
this study aimed to systematically assess the diagnostic performance of ZTE-MRI for detecting skull-base bone invasion and to explore its clinical feasibility as an alternative to CT.
Methods:
This prospective study collected 95 nasopharyngeal carcinoma patients treated in Fujian Provincial Cancer Hospital from April 2020 to December 2022 as the research subjects. The patients who do not meet the inclusion standards would be excluded. Using the GE Discovery 750W 3.0T MR scanner to obtain unenhanced scan and enhanced scan
using ZTE-MRI technology to obtain ZTE-MRI and CT image. The results of the imaging scans were used
to independently assess skull base bone invasion by two radiologists. This study was approved by the Ethics Committee of Fujian Cancer Hospital (K2025-314-01)
and informed consent from the patients were obtained.
Results:
A total of 80 nasopharyngeal carcinoma patients were included in the final analysis. There was a high degree of consistency between CT diagnosis of nasopharyngeal carcinoma skull base bone invasion and of gold standards
and the difference was statistically significant (
κ
=0.645
P
<
0.001). There was a high degree of consistency between ZTE-MRI diagnosis of nasopharyngeal carcinoma skull base bone invasion and of gold standards
and the difference was statistically significant (
κ
=0.774
P
<
0.001). There was a high degree of consistency between ZTE-MRI combined with conventional MRI diagnosis of nasopharyngeal carcinoma skull base bone invasion and gold standards
and the difference was statistically significant (
κ
=0.912
P
<
0.001).
Conclusion:
ZTE-MRI technology provides "like CT" images for the skull base bone invasion in nasopharyngeal carcinoma
and ZTE-MRI technology can replace CT examination in clinical practice.
