【 摘 要 】

Objective: to study the diagnostic importance of a new Indis software package for the postprocessing of the results of radionuclude examinations (Center for Information and Diagnostic Systems, St. Petersburg, Russia) when analyzing the results of lacrimal scintigraphy.Material and methods. Dynamic lacrimal scintigraphy was carried out in 6 volunteers (12 eyes) and 20 patients (32 years) with dacryostenosis. The examined Indis program and the known Syngo program (Siemens, Germany) were used to calculate the   elimination half-life of a radiopharmaceutical from the interest region corresponding to the whole ocular surface. The time taken to postprocess the results of the  examination was also determined.Results. When calculations were made using the Indis program and the Syngo system, the elimination half-lives of a tracer in the volunteers was 6.57±2.46 and 7.54±3.21 min, respectively. These in the patents with dacryostenosis were 69.39±65.52 and 74.85±64.59 min. With these programs, the times taken for postprocessing were 12.3±4.2 and 26.3±7.9 min, respectively.
