Abstract		Background. The purpose of this study is to analyse the contribution of multislice computed tomography (MSCT) as a diagnostic method in the diagnosis of pulmonary embolism (PE) and spectrum of findings in our material. Methods. During the period of one and a half year, we found PE in 25 patients (15 males and 10 females). The average age of the patients was 54.4 years (25 - 74). The examination was performed by »Somatom Volume Zoom« Siemens CT machine with four row detectors, with retrospective ECG gating, collimation 4 x 2.5 mm and reconstructed section with 0.8 mm. Contrast medium (130 ml) and 10 ml of saline was applied, administered with a flow rate of 3.5 ml/s and with time delay of 22 seconds. Results. During the examination, we found embolism of the main branches of pulmonary artery in 14 (56%) patients, at the right branch in 10 (40%), at the left one in 4 (16%), and bilateral pulmonary embolism in 11 (44%) patients. Subsegmental pulmonary emboli were noticed in 8 (32%) patients. Pulmonary infarct was found in 12 (48%) patients, and was followed up with ipsilateral pulmonary artery dilatation in 11 (44%) cases, redistribution of the circulation and pulmonary artery branches dilatation in infarct zone in 9 (36%) cases, contrast enhanced consolidation of pulmonary parenchyma in 10 (40%), rag zones of ground glass attenuation in 15 (60%), haemorrhage in 21 (84%), striped and reticular pulmonary drawing in 11(44%), and mosaic olighemy in 3 (12%) cases.

Summary		Izhodišča. Namen raziskave je bil ugotoviti, kakšen je prispevek večlistne računalniške tomografije (MSCT) pri diagnosticiranju pljučne embolije (PE) in kakšne spremembe smo našli pri naših bolnikih. Metode. V obdobju enega in pol leta smo PE ugotovili pri 25 bolnikih (15 moških in 70 žensk). Povprečna starost bolnikov je bila 54,4 let (25-74). Preiskave smo naredili s »Somatom Volume Zoom« Siemensovo CT napravo, ki je imela 4 detektorje, kolimator 4 x 2,5 mm in s katero smo naredili retrospektivni EKG ter rekonstruirali reze na razdaljo 0,8 mm. Aplicirali smo 130 ml kontrastnega sredstva v raztopini s hitrostjo 3,5 ml/s in z zakasnitvenim časom 22 sekund. Rezultati. Med preiskavo smo ugotovili embolizme v glavnih vejah pulmonarne arterije pri 14 (56°a) bolnikih, v desni veji pri 10 (40%) in v levi veji pri 4 (16%), bilateralne pulmonarne embolisme pa smo videli pri 11(44%) bolnikih. Subsegmentalne pljučne embolizme smo diagnosticirali pri pri 8 (32%). Pljučni infarkt smo ugotovili pri 12 (48%) bolnikih in je v 11 (44%) primerih povzročil razširitev istostranske pljučne arterije, redistribucijo cirkulacije in razširitev vej pulmonarne arterije pa smo v infarktnem področju pa smo opazili pri 9 (36%) bolnikih. Ojačanje pljučnega parenhima s kontrastom smo opazili pri 10 (40%), bolnikih, področja oslabljenja pa pri 15 (60%). Krvavitve smo opazili pri 21 (84%) bolnikih, mrežasto pljučno risbo pri 11 (44%), mozaično pa pri 3 (12%). Trombe v levem in desnem atriju smo videli samo pri 2 (8%) primerih, perikardialno krvavitev pri 1 (4%), mediastinalne bezgavke pri 1 (4%), nenadno prekinitev periferne veje z infarktom apeksa pri pri 1 (4%) ter hemoptize pri 1 (4%) primeru. Ob globoki venski trombozi smo ugotavljali kot vzrok embolizmov še okvaro delovanja srca pri 7 (28%) bolnikih in maligno obolenje pri 3 (72%). (Izvleček skrajšan na 2000 znakov)
