Abstract
Uvod: Možgansko kap klinično opredelimo kot skupek nevroloških izpadov, ki trajajo več kot 24 ur in so posledica motene prekrvavitve možganov, ki so lahko posledica zamašitve žile ali krvavitve, kjer pride do ishemije in ishemičnega infarkta dela možganov. Da je zdravnikovo zdravljenje čim bolj ustrezno, je naloga radioloških inženirjev, da z računalniško tomografsko perfuzijo in angiografijo odkrijejo področje kapi. Namen: Želimo ugotoviti, ali je računalniško tomografska angiografija pred računalniško tomografsko perfuzijo primernejši protokol za prikaz možganske kapi, kot računalniška tomografska perfuzija pred računalniško tomografsko angiografijo. Menimo, da izbira protokola ne vpliva na dobljene rezultate. Metode dela: Izbrali smo 30 pacientov s predhodno opravljeno računalniško tomografsko preiskavo možganske kapi. Od tega je imelo petnajsk pacientov opravljeno računalniško tomografsko angiografijo pred računalniško tomografsko perfuzijo, petnajst pacientov pa najprej računalniško tomografsko perfuzijo, nato računalniško tomografsko angiografijo. S tem smo želeli ugotoviti, ali prihaja do sprememb pri interpretaciji rezultatov, pri uporabi različnega vrstnega reda perfuzije in angiografije v protokolu. Rezultati: Ugotovili smo, da se povprečne vrednosti med skupinama ena (CTA pred CTP) in dva (CTP pred CTA) pri različnih vrednostih razlikujejo. Ugotovili smo, da se vrednost CBV in CBF med skupinama razlikujeta, vrednost TTP pa se med skupinama statistično ne razlikuje. Prav tako smo izvedli meritve v desni in levi jugularni veni, ter sagitalnem sinusu, kjer smo ugotovili, da se povprečne vrednosti desne in leve jugularne vene med posameznima skupinama razlikujejo, vrednosti sagitalnega sinusa, pa se med skupinama statistično ne razlikujejo. Razprava: Z raziskavo smo prišli do rezultata, da z izbiro protokola vplivamo na dobljene rezultate. Za meritve perfuzijskih parametrov je bolje izvesti protokol kjer najprej izvedemo perfuzijo, za meritve vrednosti v jugularni veni pa, da je bolje narediti protokol s predhodno narejeno angiografijo. Kateri protokol je bolje narediti, je odvisno od več dejavnikov in zaradi tega do točnih rezultatov zaradi premalo obsežne raziskave nismo prišli. Zaključek: Z našimi rezultati smo prišli do zaključka, da je potrebena izbira protokola za dokazovanje možganske kapi. Za določitev pravilnega protokola pa se je potrebno posvetovati z zdravnikom in upoštevati razne dejavnike.

Title:
Choosing a protocol for computer tomography of stroke
Abstract:
Introduction: Brain stroke is clinically defined as a set of neurological failures that last more than 24 hours and are a consequence of disturbed blood flow in the brain, which can be caused by a vein occlusion or bleeding. In order to allow appropriate treatment, radiological engineers need to perform the CT scan in order to find the location of ischemia. Purpose: We want to find out if there is any difference in the quality of the CT investigation if the CT angiography is performed before the CT perfusion or the other way around. Methods: We selected 30 patients suspection of a brain stroke. 15 patients had CT angiography before the CT perfusion and 15 patients had the CT perfusion before the CT angiography. With this retrograde examination we wanted to find out whether the order of CT scans performed influences the interpretation of the results. Results: We found out that on average the main parameters deviate. We found out that CBV and CBF betwen groups differs, on the other hand the valueof TTP does not change. In addition we have performed the measurements in the right and left jugular vein as well as in sagittal sinus, where we found out that there is a difference between the left and right jugular vein between groups, however there is no difference between sagittal sinus. Discusion: We have come to the conclusion that the selection of the protocol influences the results obtained. For the measurement of perfusion parameters, it is preferable to implement a protocol where we first perform perfusion, and for measurements of values in the jugular vein, it is better to make a protocol with previously made angiography. Which protocol is better to do, depends on several factors, and because of this, we did not arrive at accurate results due to insufficient research. Conslusion: With our results we came to the conclusion that the choice of a protocol to prove a stroke is needed. However, in order to determine the correct protocol, a doctor should be consulted and the various factors considered.
