Abstract:
Objective To investigate the value of salivagram in the diagnosis of pediatric pulmonary aspiration.Methods A total of 469 pediatric patients (age:6 weeks-16 years,average age (4.5±3.1) years;229 males,240 females) underwent salivagram.Signed informed consents were obtained.99Tcm-SC (11.1 MBq,100 μl) was dropped into the root of tongue.After the dropping,the posterior dynamic acquisition was started for 60 min,and then the anterior and posterior static images were acquired for 5 min.All patients were followed up for 3-6 months after the salivagram,and the salivagram results were analyzed.If radioactivity was shown in the main bronchus or bilateral lung fields,the pulmonary aspiration was diagnosed.Results Salivagram demonstrated positive results in 20.7％ (97/469) of the patients.However,3 patients with pulmonary aspiration showed negative results.There was no false positive result on salivagram.Conclusion Salivagram shows good results in the diagnosis of pediatric pulmonary aspiration.
