Abstract

Uvod: Dvospektralno slikanje je sodoben način zajemanja podatkov, s katerim dobimo dve seriji CT slik istega preiskovanega področja telesa. Pridobimo jih tako, da izbrano anatomsko področje slikamo z višjo in z nižjo napetostjo. Obstaja več tehnik in načinov DECT slikanja, ki se razlikujejo glede na proizvajalca. DECT se uporablja za različne diagnostične namene, med drugim tudi za diagnosticiranje pljučne embolije. Namen: Cilji diplomskega dela so ugotoviti, ali je doza pri DECTA višja ali enaka kot pri klasični CTA, preveriti kakšna količina KS se aplicira za tovrstno preiskavo in pridobitve DETCA. Metode dela: Uporabili smo deskriptivno oz. opisno metodo dela in metodo sistematičnega pregleda literature. Strokovne članke in raziskave o uporabi DECT slikanja in angiografskih preiskav pljučnih arterij za odkrivanje pljučne embolije smo iskali na bibliografskih podatkovnih bazah COBISS, Pub Med CENTRAL, Medline, DiKUL, Science Direct, CINAHL ter Springel Link. Iskanje izvedli s slovenskimi in angleškimi ključnimi besedami. Rezultati: Po pregledu sedmih podatkovnih baz smo dobili skupno 379 zadetkov. Ti zadetki so ustrezali zastavljenim vključitvenim in izključitvenim kriterijem. Na koncu smo 49 člankov podrobno prebrali in izključili tiste, ki niso odgovarjali na naš raziskovalni cilj. Za pisanje diplomskega dela smo v sistematični pregled vključili 16 dokumentov. Razprava in zaključek: Ugotovili smo, da je prejeta doza odvisna od optimizacije protokolov in da lahko z DECT slikanjem dosežemo enako ali celo nižjo dozno obremenitev za pacienta. Podobno velja za količino KS, ki je pri dvospektralnem slikanju lahko manjša kot pri klasični CTA. Glavne pridobitve DECTA pa predstavljajo različne rekonstrukcije, kot so perfuzijske in ventilacijske mape, VNC in VMI.

Secondary title: Angiography of pulmonary arteries with dual energy computed tomography
Secondary abstract: Introduction: Dual-energy computed tomography acquires two simultaneous datasets of the same anatomical structures, at different x-ray energy levels. There are different technical approaches for DECT scanning, specified by the manufacturer. In clinical practice DECT is used for diagnosing different types of pathology, such as pulmonary embolism. Purpose: The purpose of our diploma work is to find out, if is the radiation dose of DECTA higher or equivalent to conventional CTA, what quantity of iodine contrast medium is used for DECTA and what advantages offers DECTA. Methods: We used a descriptive research method and did a systematic literature review. We searched for articles about DECT and pulmonary angiography for diagnose pulmonary embolism. We reviewed the following databases: COBISS, Pub Med CENTRAL, Medline, DiKUL, Science Direct, CINAHL and Springel Link. All documents were searched with key words in Slovene and English language. Results: After review of seven databases, we found 379 useful documents. We reduced selection to 49 articles and then excluded documents, which weren't answering to our goals. In diploma work we presented results of only 16 suitable articles. Discussion and conclusion: Based on the analyzed articles we found out, that radiation dose depends on protocol optimization, but DETCA has comparable or even reduced radiation dose than convencial CTA. Also used quantity of iodine contrast medium can be lower for DECTA in comperison to CTA. Main advantages of DECTA are image reconstructions, like pulmonary perfusion and ventilation maps, VNC and VMI.
