Abstract

Objectives: To study the clinical value of Dual-Energy Virtual Non-Contrast CT scan for subarachnoid hemorrhage. Methods: 30 patients of subarachnoid hemorrhage were selected, they received Dual-Source Conventional Non-Contrast CT scans and head angiography with Dual-Energy CT. Then Liver Virtual Non-Contrast program was used to reconstruct the images. After that the Conventional Non-Contrast images were taken as gold standard to evaluate the clinical value of Virtual Non-Contrast technology in the following aspects: Signal-Noise Ratio, Radiation Dose and lesion diagnosis. Results: The Signal-Noise Ratio of Virtual Non-Contrast CT scan was (4.21 ± 0.5), the Signal-Noise Ratio of Conventional Non-Contrast CT scan was (10.39 ± 0.71), the latter was significantly higher than the former. The Dose Length Product of Virtual Non-contrast CT scan was （121.30±3.8）, it was close to 1/6 of the Dose Length Product (697.6±4.2）of the Conventional Non-Contrast CT scan. As for the lesion area, the difference of the CT values between the Virtual Non-Contrast and the Conventional Non-Contrast CT scan was only 4~10Hu. In addition, the Virtual Non-Contrast images’ quality was graded by diagnostic teachers: there were 4 cases of 3 points, 23 cases of 2 points, 3 case of 1 point. Conclusions: Compared with the Conventional Non-Contrast images, there is greater noise in the Virtual Non-Contrast images, but the latter can meet the clinical diagnostic requirements and greatly reduce the radiation dose. Advances in knowledge: Virtual Non-Contrast technology was used for the diagnoses of subarachnoid hemorrhage, and the radiation dose was greatly reduced.
