Abstract

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. 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. 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. The investigation showed the practical significance of the Indis software package in processing the data of lacrimal scintigraphy. The calculations made with the Indis program correspond to those made with the known Syngo program. The convenience and ergonomics of the program can precisely identify the region of interest. The economic justification of the system is associated with the shorter time taken to postprocess and interpret the results of lacrimal scintigraphy. The Indis software package may be recommended for use in the examination and treatment monitoring in patients with abnormal lacrimaton.
