However, its utilization among young adults, particularly undergraduates, is very low. The aim of the present study was to determine the prevalence and predictors of non-uptake of VCT among undergraduates. </span><b><span style="font-family:Verdana;">Methods: </span></b><span style="font-family:Verdana;">A cross sectional study using quantitative methods was conducted. Using simple random sampling, three faculties were selected out of nine and 422 respondents were selected from three faculties. Interviews were conducted using pre-tested semi-structured questionnaires. Data analysis was done using statistical package for social sciences version 20. Prevalence was measured by the percentage of respondents that had never used VCT. Analytical statistics were done using chi-square test to measure strength of association between VCT uptake and knowledge and attitude of respondents.

The associations were presented as odds ratios (OR) and 95% confidence intervals.</span><b><span style="font-family:Verdana;"> Results: </span></b><span style="font-family:Verdana;">Overall, 59.3% of respondents were knowledgeable about VCT while majority, 64.7% had negative attitude towards it. Knowledge (X</span><sup><span style="font-family:Verdana;">2</span></sup><span style="font-family:Verdana;"> = 9.89, P-value < 0.001) and attitude (X</span><sup><span style="font-family:Verdana;">2</span></sup><span style="font-family:Verdana;"> = 10.78, P-value < 0.001) showed statistically significant 展开更多

目的探讨肿瘤阳性显像剂肺内非特异性摄取SPECT/CT显像特点、鉴别方法以及形成的原因。方法回顾性分析2014年9月至2016年3月在北京协和医院核医学科行^(99m)Tc-甲氧基异丁基异腈(methoxy isobutyl isonitrile,MIBI)和^(99m)Tc-HYNIC-TOC... 目的探讨肿瘤阳性显像剂肺内非特异性摄取SPECT/CT显像特点、鉴别方法以及形成的原因。方法回顾性分析2014年9月至2016年3月在北京协和医院核医学科行^(99m)Tc-甲氧基异丁基异腈(methoxy isobutyl isonitrile,MIBI)和^(99m)Tc-HYNIC-TOC SPECT显像(含胸部显像),胸部可见异常放射性浓聚但同机或异机融合CT均未提示占位性病变的患者。观察胸部异常浓聚灶的特点,勾画摄取部位感兴趣区,并在对侧同水平复制勾画感兴趣区,计算平均摄取值及靶/本底比值。收集患者的临床资料,包括病史、其他影像学及实验室检查结果。结果 5668例行^(99m)Tc-MIBI和^(99m)Tc-HYNIC-TOC SPECT显像(含胸部显像)的患者中,出现胸部异常放射性浓聚灶并行同机或异机融合CT均未提示占位性病变者共11例,其中使用^(99m)Tc-MIBI显像5例,^(99m)TcHYNIC-TOC显像6例。11例异常浓聚灶形态均为圆形,右肺5例,左肺6例。靶/本底比值分别为2.66、4.01、6.96、8.19、10.50、11.16、11.16、14.89、15.16、28.13和32.64。11例患者的病史、药物使用史及实验室检查均无交叉(临床资料不相同)。结论肺内非特异性摄取易发生在使用^(99m)Tc-MIBI和^(99m)Tc-HYNIC-TOC示踪剂进行显像的核医学检查中,可能与这两种示踪剂形成微小栓子栓塞肺内血管有关;平面显像与肺部肿瘤性病变鉴别困难,SPECT/CT融合显像联合有助于除外这种肺内的非特异性摄取。 展开更多
