Abstract
Ubrzanim razvojem, kako tehnologije, tako i same medicine, dolazi do usavršavanja uređaja magnetske rezonancije (MR) te danas on spada u standardne dijagnostičke pretrage. Tijekom snimanja često se koriste kontrastna sredstva čija je glavna uloga prikazivanje razlike između patološkoga i normalnoga tkiva. Najčešće korištena kontrastna sredstva su gadolinijska koja se sastoje od iona gadolinija i molekule nosača odnosno kelata. MR angiografija (MRA), koristi veoma snažno magnetsko polje, radiovalove i snažni računalni sustav za procjenu krvnih žila i prikazuje abnormalnosti krvnih žila ili stupanj ateroskleroze ili okluzije. Ne koristi ionizirajuće zračenje već radiofrekventni impulse koji poravnjaju atome vodika unutar tijela. Zbog potrebe za većim FOV-om trenutno se koriste se uređaji MR-e jačine 1.5 T. Koriste se razne zavojnice za periferne krvne žile koje pružaju veći omjer SNR-a i CNR-a. Koriste se također MR kompaktibilne manžete ili torpedice zbog održavanja kompresije kako ne bi došlo do venske kontaminacije. Veoma je bitno da pacijent bude miran za vrijeme trajanja pretrage kako se na slikama ne bi očitovali artefakti. Gadolinijska se kontrastna sredstva injiciraju intravenski kao bolus doze i snimaju se u arterijskoj fazi, obično se pacijentu daje 45 mL kontrastnoga sredstva. Alergijske su reakcije veoma rijetke. Prilikom obrade slike sa kontrastom se subtrahiraju s nativnim slikama kako bi se okolna tkiva i signali uklonili. Kao i za većinu pretraga postoje kontraindikacije za MR angiografiju kao što su: pacemakeri, umjetni srčani zalisci, implantati, biostimulatori, automatski kožni injektor lijekova. U posljednjem je desetljeću, MRA periferije evoluirala u jednu od najsigurnijih, najbržih i preciznijih neinvaznivnih dijagnostičkih metoda za procjenu perifernih vaskularnih bolesti, a u bliskoj će budućnosti evoluirati još više.
Abstract (english)
Accelerated development, both technology and medicine, improves magnetic resonance (MR) imaging and nowadays is standardized diagnostic procedure. During the procedure, contrast media are often used to show the difference between pathological and normal tissue. The most common used contrast media are gadolinium which consists of gadolinium ions and chelates carries. MR angiography (MRA) uses a powerful magnetic field, radio waves and a powerful computer system for evaluating blood vessels and it shows abnormal blood vessels or the degree of atherosclerosis or occlusion. It does not use ionizing radiation but it uses a radiofrequency pulse that aligns the hydrogen atoms in the body. Because of the need for larger FOVs, MR devices of 1.5 T strength are currently being used. Various coils for peripheral blood vessles are used which provide a greater ratio of SNR and CNR. Also are used MR appropriate cuffs or torque wraps for maintaining compression so we could avoid the occurrence of venous contamination. It is very important that the patient, during the procedure, is calmed to avoid the artefacts in the images. Gadolinic contrast medias are injected intraveniously as a bolus dose and recorded in arterial phase, usually giving 45 mL contrast agents to the patient. Allergic reactions are very rare. When processing a contrast image, it is subtracted with native images to remove surrounding tissue and signals. As with most medical procedures, there are few contraindications for MRA like: pacemakers, artificial heart’s implants, biostimulators, automatic skin injectors. In the last decades, MRA peripheries has evolved into one of the safest, fastest and more precises non invasive diagnostic methods for estimating peripherial vascular diseases and will be evolving even more in the near future.
