本文报告了1993-1996年应用彩色多普勒超声检查,并经手术病理证实或X线CT及随访3年以上的14例脾脏占位性病变。其中良性肿瘤8例,恶性肿瘤6例。并就二维图像、彩色多普勒血流特征及血流参数测值进行分析讨论。认为脾脏良性肿瘤CDFI示瘤体内及周边可有丰富的血供,但大多为静脉血流,部分可为动脉血流,但都呈低速低阻动脉频谱。Vmax最大为45cm/s,RI≤0.60;而恶性肿瘤多表现为动脉血供,且为高速高阻的动脉频谱。Vmax最大可达141cm/s,RI≤0.65。
This article reports the 1993-1996 application of color Doppler ultrasound and confirmed by surgery or X-ray CT and follow-up of more than 3 years of spleen-space-occupying lesions. Of which 8 cases of benign tumors, 6 cases of malignant tumors. And two-dimensional images, color Doppler flow characteristics and blood flow parameters measured to discuss the discussion. It is considered that the spleen benign tumor CDFI can show abundant blood supply in and around the tumor, but most of them are venous blood flow, and some of them can be arterial blood flow, but all show low frequency and low resistance arterial frequency spectrum. Vmax maximum of 45cm / s, RI ≤ 0.60; and malignant tumors showed arterial blood supply, and high-speed high-impedance artery spectrum. Vmax up to 141cm / s, RI ≤ 0.65.
