UPORABA RAČUNALNIŠKOTOMOGRAFSKE ANGIOGRAFIJE IN BREZKONTRASTNE MAGNETNO RESONANČNE ANGIOGRAFIJE PRI ODKRIVANJU ZOŽITEVVRATNEGA OŽILJA. (Slovenian)

USE OF COMPUTER TOMOGRAPHY ANGIOGRAPHY AND NON CONTRAST MAGNETIC RESONANCE ANGIOGRAPHY IN DETECTING OF VASCULAR STENOSIS IN NECK AREA. (English)

Introduction and aim: The aim of the study was to compare two similar methods for detecting stenosys in neck area. The standard of CTA and MRA (Inhance 3D Inlow Inversion Recovery) procedures will be presented. Methods: Diagnosis of neck area vessel is usually starting with US and then upgraded with CTA or MRA. With the patients who were appointed for the CTA, we have just performed additional examination i.e. MRA (Inhance 3D Inflow Inversion Recovery) on 3T. Comparing the results we are able to establish adequate method for regular use. Results and discussion: Interpretation of results was performed on advanced workstations. The aim of interpretation was applicability of both methods for advance endoluminal or surgical treatment. On the basis of above results we have also changed some parts of protocols. Conclusions: Both methods give good results. The CTA requires the use of iodine contrast agents while the MRA (Inhance 3D Inflow Inversion Recovery) is a more straightforward and non-invasive method; However CTA is still the standard tool for vessel diagnosis and advance treatment in neck area. MRA (Inhance 3D Inflow Inversion Recovery) is comparable to CTA. [ABSTRACT FROM AUTHOR]

Uvodin namen: Pri odkrivanju zožitev vratnega ožilja uporabljamo Dopplerjev ultrazvok, računalniško tomografsko angiografijo in magnetno resnonančno angiografijo brez kontrastnega sredstva. Prikazali bomo razlike in podobnosti teh metod in določili kaj je standard, če hočemo zagotoviti pacientu najmanjšo dozo. Metodedela: Pri opravljanju diagnostike vratnega ožilja začnemo navadno z ultrazvokom, ki ga nato nadgradimo z eno od v uvodu naštetih metod. Pri pacientih, ki izpolnjujejo pogoje za računalniško tomografsko angiografijo, v Univerzitetnem kliničnem centru Maribor predhodno opravimo magnetno resnonančno angiografijo (Inhance 3D Inflovv Inversion Recovery) brez kontrastnega sredstva na magnetno resonančnem aparatu 3T. Za raziskavo smo izbrali 29 redno naročenih pacientov, ki smo jim opravili obe preiskavi. Po obdelavi podatkov smo primerjali lumen prikazane žile, polnitvene motnje, razliko izmerjene zožitve, oceno mehkega plaka na računalniškotomografskih in magnetno resonančnih slikah. Podatke smo primerjali in določili katera vrsta preiskave ima večjo diagnostično glede na diagnostični problem. Rezultatiin razprava: Rezultate smo interpretirali s pomočjo podatkov, shranjenih na delovnih postajah. Prišli smo do zaključka da je vsaka od metod uporabna, nedvomno je CTA metoda izbire, pod določenimi predhodnimi diagnostičnimi pogoji pa je MRA primerljiva. Na izbiro metode vpliva zdravnikova odločitev glede na nadaljnje zdravljenje in pacientovo zdravstveno stanje. Zaključek: CTA ostaja še vedno zlati standard pred zdravljenjem. Pri preiskovancih ki so v istem dnevu opravili obe preiskavi smo dokazali da je MRA (Inhance 3D Inflovv Inversion Recovery) po predhodno opravljenim diagnostičnim ultrazvokom enakovreden CTA.
