Abstract
|
|
|
Purpose : The purpose of this study was to evaluate the morphology and vascular architecture of the lesion site in the diagnosis and treatment planning of cerebrovascular disease by 2D, 3D DSA (Digital subtraction angiography) and 4D DSA (Time-resolved 3D rotation angiography) And to compare their usefulness.
Subjects and Methods : The test equipment was the Siemens Artis ZEE biplane, Syngo X workstation, and Infinity PACS. Twenty-four patients were involved in this study from May, 2017 to March, 2018. The patients were 24 patients with cerebral arteriovenous malformation, dural arteriovenous fistula, and superficial temporal artery to middle cerebral artery bypass graft Follow-up. They had an Angiographic exploration with both 4D DSA and 2D DSA. 4D DSA images were reconstructed into 3D images. One radiologist and two radiological technologists with at least 10 years of experience in nerve intervention were evaluated. In order to evaluate the significance of the experiment, the SPSS v25 correspondence Normality test and Non-parametric statistical test were performed.
Result : Diagnostic data of cerebrovascular disease showed that the mean of 2D and 3D DSA was higher than 4D DSA test, but there was no statistically significant difference. (p>.588)
Conclusion : In this study, 4D DSA reconstructions was largely equivalent to that of the combined 2D, 3D DSA studies.
