    Abstract
  • Objective To explore the application of rapid double-energy CT scan in the direct enhancement of bilateral lower limb veins (DE-DSCTV), and the advantages of the direct enhancement method relative to the indirect enhancement method. Methods Thirty patients with lower limb venous disease were selected. The dual-energy CT enhanced scan of bilateral lower extremities was performed by improving the injection mode of high-pressure syringe. 3D vascular images were obtained by post-processing and compared with the previous indirect enhancement CTV image of the same patient. Judging the feasibility of the direct method to enhance the venography of bilateral lower extremities, and whether the direct enhancement method DE-DSCTV is more advantageous. Results All 30 patients had higher contrast, clearer and more accurate images, which greatly improved the detection rate of lesions. Conclusion Bilateral lower extremities venous double energy CT direct enhanced CTV is a low dose and low contrast medium examination. The direct enhanced images of both lower extremities can be obtained simultaneously by one scan. Compared with the indirect enhancement method, the image obtained by the direct enhancement method has a higher contrast, which is more favorable for the detection of the focus, and the imaging effect is satisfactory.
