IZVLEČEK
Uvod in namen: Namen te študije je predstaviti preiskavo 
MRI kolena v klinični praksi z uporabo MR aparatov jakosti 
1,5T in 3T. Ta izvleček temelji na iskanju znanstvene literature, 
objavljene na platformi Pubmed od leta 2009 do 2021.
Metode: Protokoli slikanja kolena običajno trajajo 20–40 minut, 
odvisno od slikovnega polja, patologije, števila sekvenc in 
debeline rezine. Protokol hitrega slikanja kolen na aparatu MR 
3T lahko traja 10 minut, hkrati pa zagotavlja visokokakovostne 
slike. Glede na ESSR so protokoli za slikanje kolena sestavljeni 
iz T2 TSE FS ali PD FS sekvenc in T1 v koronarni, aksialni in 
sagitalni ravnini ter T2 aksialni poševnini za oceno ACL.
Rezultati: Vključenih je bilo 563 študij. Po uporabi meril 
za izključitev je bilo izbranih 16 kliničnih študij za analizo 
diagnostične natančnosti 1,5T in 3T MRI za poškodbe 
kolenskega sklepa, hrustanca, vezi in meniskusa. V vseh študijah 
je bila artroskopija referenčni standard. Za lezije sklepnega 
hrustanca se je AUC za 1,5T MRI bistveno razlikovala od 3T MRI 
(Z = 3,4, P < ,05). Za lezije znotraj ligamentov in meniskusa se 
vrednosti AUC za 1,5T MRI niso bistveno razlikovale od tistih 
za 3T MRI (Z = 0,32; P > ,05 in Z = 0,33; P > ,05).
Zaključek: Rezultati kažejo, da tako 1,5T kot 3T MRI nudita 
visoko diagnostično natančnost pri poškodbah kolena, ki 
vključujejo poškodbo meniskusov ali ligamentov. 3T MRI 
ponuja večjo diagnostično natančnost kot 1,5T MRI za lezije 
sklepnega hrustanca.

ABSTRACT
Introduction and purpose: The aim of this study is to present 
the use of 1.5T and 3T knee MRI in everyday clinical practice. 
This abstract is based on a search of the scientifi c literature 
published on the Pubmed platform from 2009 to 2021.
Methods: Knee imaging protocols usually take 20–40 
minutes, depending on the imaging fi eld, pathology, number 
of sequences and slice thickness. Fast knee imaging protocol 
on 3T MRI can last 10 minutes while providing high quality 
images. According to ESSR knee imaging protocols consist of 
T2 TSE FS or proton density FS sequences and T1 sequences 
in coronal, axial and sagital plane and T2 axial oblique for ACL 
evaluation.
Results: The initial search included 563 studies. After applying 
exclusion criteria, 16 clinical studies were selected to analyze 
the diagnostic accuracy od 1.5T and 3T MRI for lesions of the 
knee joint, cartilage, ligaments and meniscus. In all studies, 
arthroscopy was the reference standard. For lesions within the 
articular cartilage, the AUC for 1.5T MRI diff ered signifi cantly 
from 3T MRI (Z = 3.4, P < .05). For lesions within the ligaments 
and meniscus, the AUC values for 1.5T MRI did not diff er 
signifi cantly from those for 3T MRI (Z = 0.32, P > .05, and Z = 0.33, 
P > .05, respectively).
Conclusion: Results indicate that both 1.5T and 3T MRI off er 
high diagnostic accuracy and clinical relevance for knee 
injuries involving the meniscus or a ligament. However, the 
present meta-analysis indicates that 3T MRI off ers greater 
diagnostic accuracy than 1.5T MRI for articular cartilage 
lesions.
