8 (6): 475-6. The 17 included studies had a total of 1308 subjects, of whom either had myocarditis (Table 2) or were part of the control group (Table 3). The Lake Louise criteria (LLC) are currently the recommended diagnostic cardiac magnetic resonance (CMR) imaging criteria for patients with suspected myocarditis.5 LLC use tissue-based CMR markers consisting of T2-weighted (T2w) ratio, early gadolinium enhancement (EGE), and late gadolinium enhancement (LGE). 2009;53 (17): 1475-87. One patient had recovered from COVID-19 earlier in 2020, but because of persistent symptoms, evaluation for myocarditis was performed. A total of 145 competitive student athletes (108 male and 37 female individuals; mean age, 20 years; range, 17-23 years) recovering from COVID-19 were included. Recently, T2-mapping has been suggested as a quantitative ap-proach to edema imaging, allowing for a more sensitive The data also suggest that T 2 mapping has acceptable diagnostic performance for All athletes who tested positive for COVID-19 at our institution have undergone MRI. Since the inception of LLC, quantitative imaging with T1 and T2 mapping has made significant advancements in assessing diffuse myocardial injury.68 Novel techniques such as native T1 and T2 mapping or extracellular volume (ECV) calculations have been shown to provide additional diagnostic information in patients with myocarditis.911 Although some studies have shown quantitative mapping techniques are superior to LLC,1113 their performance across the literature remains unclear.

The basics of MR physics with the steps of image formation. Myocarditis is a known cause of sudden cardiac death in athletes,10 even occurring in patients with preserved systolic left ventricular (LV) function.11 Given emerging reports of COVID-19associated MRI findings consistent with myocarditis, the question arises as to whether athletes recovering from COVID-19 should be evaluated with MRI.6 While myocarditis is an uncommon finding in COVID-19 autopsy reports (1%-7%),12 a recent case series6 reported MRI findings consistent with myocarditis in 4 of 26 athletes (15%) recovering from COVID-19. et al. The Data Supplement is available at https://www.ahajournals.org/journal/circimaging/doi/suppl/10.1161/CIRCIMAGING.118.007598. Sudden cardiac death in Air Force recruits. Expressed as pooled estimate with 95% confidence interval. Imaged at 3 T, native T1-weighted time in areas demonstrating LGE was 1250 milliseconds. After outbreaks of the novel coronavirus disease 2019 (COVID-19) in late 2019 and 2020, complications of this disease1,2 including myocarditis were reported.3-6 Myocarditis is an inflammatory condition associated with viral infections.7,8 Manifestations of myocarditis are varied, ranging from mild disease to serious complications, including heart failure and sudden cardiac death.8 Recommended diagnostic testing includes serum troponin levels, electrocardiogram (ECG), transthoracic echocardiography (TTE), and cardiac magnetic resonance imaging (MRI).9. This book presents all the publicly available questions from the PISA surveys. Some of these questions were used in the PISA 2000, 2003 and 2006 surveys and others were used in developing and trying out the assessment. Sensitivity analysis showed that exclusion of Radunski et al10 significantly reduced heterogeneity for T1 sensitivity (P[Cochran Q]=0.11; I2=41.6%) and T2 sensitivity (P[Cochran Q]=0.08; I2=51.5%). Although non-specific, cardiac creatine kinase (CK) and troponins I, T and C (TnI, TnT and TnC) are elevated. Abstracts were independently reviewed and selected by 2 investigators (J.A.P., Y.J.L.) Native T1-mapping detects the location, extent and patterns of acute myocarditis without the need for gadolinium contrast agents. This book provides a comprehensive overview of the practical aspects of contrast echocardiography. In addition, many studies have opted to use only T2w and LGE for diagnosis of myocarditis as it has shown comparable accuracy.30,32,34 In the study by von Knobelsdorff-Brenkenhoff et al,28 they combined various parameters including native T1 mapping, T2 mapping, ECV, LGE, and T2w ratio.
