目的 探讨SSD(shadedsurfacedisplay)血管成像在肺结节性病变中的应用价值。方法 对 47例患者、50个肺结节性病变增强后行结节处血管的SSD成像,分析结节处血管表现及与定性的关系。结果 50个肺结节中, 38个SSD重建后图像显示清晰,其中 31个为恶性结节, 7个为良性结节。恶性结节中, 20例出现结节处血管增粗、增多, 4例仅见单根血管增粗, 1例出现结节处血管增多、未见增粗, 6例可见血管穿过结节(3例同时发现合并血管增多、增粗 ), 3例结节处血管未见明显异常;良性结节中, 1例见血管增粗、增多, 1例仅见血管增粗, 3例出现结节处血管增多、未见增粗, 2例结节处血管未见明显异常。结论 ①SSD重建后示结节处血管增粗或穿过结节提示恶性结节可能性大。②SSD血管成像对位于中外带肺野的肺结节性病变的定性诊断更有帮助。
Objective To investigate the value of SSD (shaded surfacedisplay) vascular imaging in pulmonary nodular lesions. Methods Forty-seven patients with 50 pulmonary nodular lesions were retrospectively analyzed for SSD imaging of nodules, and the relationship between nodules’ blood vessels and qualitative features was analyzed. Results Of the 50 lung nodules, 38 SSDs showed clear images after reconstruction. Among them, 31 were malignant nodules and 7 were benign nodules. Malignant nodules, nodules in 20 cases showed thickening of blood vessels, increased in 4 cases, only a single vessel thickening, nodules in 1 case of vascular increased, no thickening, 6 cases of visible blood vessels through the nodules (3 In the case of benign nodules, one of the benign nodules showed thickening of the blood vessels, an increase of only one vessel, and only one of the three vessels showed nodules at the vessel Increased, no thickening, 2 cases of nodules at the blood vessels showed no significant abnormalities. Conclusion ①SSD reconstruction showed nodules vascular thickening or nodules through the possibility of malignant nodules. ② SDSD angiography is more helpful for the qualitative diagnosis of pulmonary nodular lesions located in the lung field of the middle and outer belt.
