Abstract		Background. The aim of the stndy was to evaluate the accuracy of chest sonography in the radiological diagnosis of small pleural effusions. Patients and methods. Patients referred for abdominal and/or chest sonographies for various reasons were examined for sonographic features of pleural effusion. From January 1997 till January 2000, 69 patients were included into the study. Fifty-two patients were found to have pleural effusion not exceeding 15 mm in depth, the rest of them served as controls. Subsequently erect posteroanterior and expiratory lateral decubitus projections were done in all patients. Results. Compared to radiologicai examination chest sonography had a positive predictive value of 92% in the diagnosis of small pleural effusions in our study population. The mean thickness of fluid was 9.2 mrn on ultrasonography and 7.6 mm on expiratory lateral decubitus views (P<0.01). Conclusions. Chest sonography showed a high degree of accuracy for demonstrating small pleural effusions and could repIace lateral decubitus chest radiographs adequately.
Summary		Izhodišča. Namen raziskave je bil opredeliti zanesljivost ultrazvočne preiskave plevralnega prostora v radiološki diagnostiki malih plevralnih izlivov. Bolniki in metode. Pri bolnikih, ki so bili zaradi različnih vzrokov napoteni na ultrazvočne preiskave trebuha in/ali plevralnega prostora, sem iskal ultrazvočne značilnosti plevralnih izlivov. Med januarjem 1997 in januarjem 2000 sem v raziskavo vključil 69 bolnikov. Pri 52 bolnikih sem našel izliv, ki ni presegal debeline 15 mm; ostali so predstavljali kontrolno skupino. Takoj zatem smo vsem naredili rentgenske posnetke prsnih organov stoje v postero-anterioriorni smeri in leže na boku v fazi izdiha. Rezultati. Pozitivna napovedna vrednost ultrazvočne preiskave plevralnega prostora v diagnostiki malih plevralnih izlivov je 92% primerjalno z radiološkima preiskavama. Povprečna debelina plašča tekočine je bila ultrazvočno 9,2 mm in 7,6 mm na posnetkih leže na boku v fazi izdiha (P<0.01). Zaključki. Ultrazvočna preiskava plevralnega prostora kaže visoko stopnjo zanesljivosti v diagnostiki malih plevralnih izlivov in lahko ustrezno nadomesti rentgenske posnetke leže na boku.
