Abstrakt		Purpose. To evaluate the usefulness of expirium lateral decubitus views in the radiological diagnosis of small pleural effusions. Materials and methods. Patients referred to abdominal sonography for different reasons were routinely checked for possible pleural effusion. From November 1994 till May 1996, 36 such patients were found to have pleural effusion not exceeding 15 mm and were included in the study. Patients were examined radiologically in erect PA and lateral projections and, after 5 min. in decubitus position, in inspiratory-expiratory lateral decubitus projections with 10 hip elevation and central beam on the lateral chest wall. Results. In 22 out of 36 patients (61 %), the pleural fluid was not visible on erect PA and lateral chest radiogram. However, the fluid was visible in 35/36 patients (97%) in expirium from lateral decubitus view. The average thickness of fluid from lateral decubitus views in inspirium and expirium was 4.3 and 7.9 mm, respectively. In 31 out of 36 patients (86%), the thickness of the fluid layer as measured in expirium and inspirium was different. In 16%, the fluid was not visible on inspirium lateral decubitus projections. Conclusions. Radiography turned out to be almost as sensitive as sonography in detection of small pleural effusions. Lateral decubitus views taken in expirium contributed essentially to the diagnostic sensitivity in our study.
Izvleček		Namen. Ugotoviti uporabnost dveh posnetkov v bočnem položaju v različnih fazah dihanja (v globokem vdihu in v izdihu) pri diagnostiki majhnih plevralnih izlivov. Materiali in metode. Bolnikom, ki so bili na UZ pregledu trebuha zaradi različnih vzrokov, smo rutinsko pregledovali tudi plevralni prostor in iskali izlive. Od novembra 1994 do maja 1996 smo pri 36 bolnikih našli mali plevralni izliv do širine 15 mm bazalno in jih vključili v študijo. Slikali smo jim prsne organe v PA in stranski smeri. Nato so 5 min ležali na boku, nakar smo jim napravili posnetek v izdihu in vdihu leže na boku. Ob tem so imeli za 10 dvignjeno medenico, centralni žarek pa je bil usmerjen na stranico prsnega koša. Rezultati. Pri 22 od 36 bolnikov (61%) na PA in stranskih posnetkih ni bilo znakov plevralnega izliva. Zato pa je bil ta jasno viden pri 35 od 36 bolnikov na posnetku leže na boku, napravljenem v izdihu. Povprečna širina tekočinske plasti je znašala 4,3 mm na posnetku leže na boku v vdihu in 7,9 mm na posnetku v izdihu. Pri 31 od 36 bolnikov (86%) sta se širini tekočinske plasti, izmerjeni na posnetkih leže na boku v vdihu in izdihu razlikovali. V 16% tekočine na posnetku leže na boku v inspiriju ni bilo videti. Zaključek. Izkazalo se je, da so rentgenski posnetki prsnih organov v ustreznih smereh ravno tako občutljiva metoda za ugotavljanje malih plevralnih izlivov kot pregled z ultrazvokom. Rezultati naše študije kažejo tudi, da posnetek leže na boku, napravljen v izdihu, ključno prispeva k občutljivosti metode.
