对127例(164个病灶)软组织血管病变患者作了~(99m)Tc-RBC血流血池显像,通过肉眼观片结合感兴趣区(ROI)技术对软组织血管病变影像进行判断。结果,111例显像阳性,检出率为87.40％,133个病灶显像阳性,病灶检出率为81.10％。通过x~2检验显示病灶类型、部位及其大小对检出率具有显著影响(P<0.001或P<0.005)。结果提示~(99m)Tc-RBC血流血池显像对小儿软组织血管病变探测用于:①大面积及多发病变;②位于四肢及头颈部病变;③有碘过敏而不能行X线血管造影的病例。
99m Tc-RBC blood flow imaging was performed in 127 patients (164 lesions) of soft tissue vascular lesions. The soft tissue vascular lesion images were judged by the naked eye view combined with the region of interest (ROI) technique. Results, 111 cases were imaging positive, the detection rate was 87.40%, 133 lesions were imaging positive, the detection rate was 81.10% lesions. By x ~ 2 test showed that the type of lesion, location and size of the detection rate had a significant impact (P <0.001 or P <0.005). The results suggest that ~ (99m) Tc-RBC blood flow imaging in the detection of soft tissue vascular lesions in children for: ① large area and multiple lesions; ② located in limbs and head and neck lesions; ③ iodine allergy and can not line X-ray Case of contrast.
