灵敏度

Correct diagnosis were made in 34 malignancies and 6 false positive lesions were excluded based on moiphology and 18F-FDG uptake status of the lesion. There were 6 false positive and 2 false negative cases. Furthermore, extrathoracic metastases which were not showed on previous CT image in 4 patients including one in the adrenal gland and 3 in the bone were detected by 18F-FDG imaging.

根据形态及核素摄取特征，18F-FDG符合线路显像正确检出恶性病变34例，排除恶性病变6例，出现假阳性6例和假阴性2例，对原发肺癌诊断的灵敏度、特异性和准确性分别为94.4％、50.0％和83.3％；同时，在4例患者中检出了CT未发现的、发生于肾上腺和骨的肺外转移。

The results showed: Fragilaria brevistriata had the highest average difference in temperature to respond to heavy metals, it was 0.24 ℃ that was 0.05 ℃ high more 0.19 ℃ of together average difference in temperature of eight kinds of algae to respond to heavy metals; The percent of Fragilaria brevistriata responding better to the reagents was 80% that was the highest in eight kinds of algae; The average response time of Fragilaria brevistriata responding to the reagents was 4.65 min that was low more 5.21 min of together average response time of eight kinds of algae; Fragilaria brevistriata' sensitivity was between 0.06 mgL^(-1) and 7.0 mgL^(-1), and the luminescent bacteria' sensitivity was between 0.07 mgL^(-1) and 15.3 mgL^(-1), so Fragilaria brevistriata had lower dose to respond to the heavy metals.

结果表明：平均响应温差短线脆杆藻最大，为0.24℃，高出8种藻的0.19℃总平均温差0.05℃；较好药品响应率短线脆杆藻最高，为80%；平均响应时间短线脆杆藻居中，为4.65min，低于8种藻的总平均响应时间5.21min；短线脆杆藻对重金属的灵敏度在0.06~7.0mgL^(-1)之间，发光细菌在0.07~15.3mgL^(-1)之间，表明短线脆杆藻对重金属响应的剂量低。
