Summary of the studies identified in the systematic review that investigated topics other than the diagnostic accuracy of MRI

Author Year Topic Finding
W Bom50 2020 The diagnostic accuracy of different imaging modalities for discriminating complicated from simple appendicitis a The available evidence was not sufficient for conducting a meta-analysis
A Agathis51 2019 The trend of MRI use according to the American College of Surgeons database Of the 11,841 patients that received an appendicectomy in 2016, only 36 adult patients had received MRI
O Ozdemir52 2018 The utility of MRI in follow-up assessment MRI was useful in the follow-up assessment of simple appendicitis cases after initial medical management
N D'Souza5 2018 Financial implications of imaging use for suspected appendicitis The reduction in healthcare cost due to routine imaging was 68% less when using MRI instead of CT
V Tan53 2017 The trends of MRI use at 16 Canadian centres MRI was generally not used for assessing appendicitis in non-pregnant adults in Canada, even at centres having MRI available 24 hours a day
M Agapova54 2017 Imaging preferences of U.S. physicians Radiologists generally preferred contrast-enhanced CT over MRI to assess suspected appendicitis, whilst ED physicians had minimal preference in choosing between contrast-enhanced CT and MRI
M Repplinger55 2016 The trend of MRI use at one U.S. academic centre MRI was never used for evaluating adults suspected of appendicitis between 1992 and 2014
S Kiatpongsan56 2014 Decision analysis on the benefits of MRI use The advantage of MRI in minimising radiation exposure is substantial only if MRI demonstrates a minimum sensitivity of 91% when specificity is 100%, or minimum specificity of 62% when sensitivity is 100%
M Leeuwenburgh57 2012 Training of radiologists for interpreting MRI Training of radiologists can improve the diagnostic accuracy of MRI for appendicitis
J Horowitz58 2011 Visualising normal appendixes T2-weighted MRI could visualise 80% of normal appendixes
P Nikolaidis59 2006 Visualising normal appendixes The reliability of MRI in visualising normal appendixes was variable
M Beinfield60 2005 Costs of MRI use The costs of MRI varied significantly between 1996 and 2002

aThis was a secondary study that investigated MRI, CT, and ultrasound. However, due to the insufficient evidence regarding MRI and ultrasound, meta-analysis was conducted only for CT
