“…As far as defining the extent of major and significant findings, we found the definitions in the study published by Atalay et al, 6 as satisfactory for the purposes of our study. Major findings according to our study were those that were important enough to warrant highlighting to the clinical team but not always causing delay or cancellation of AAA repair.…”

Objective: Many major vascular centres, including ours, incorporate coverage of the thoracic aorta in CT scans evaluating abdominal aortic aneurysms (AAAs) (extended coverage contrast-enhanced CT (EC-CECT) scan]. We sought to determine the prevalence of thoracic pathology in a large consecutive series of patients with AAA undergoing EC-CECT. Methods: All patients who underwent EC-CECT for AAA between April 2013 and 2014 were identified from our radiology information system. Reports were retrospectively reviewed and for each study, sex, age and reported thoracic aortic and other non-vascular findings were extracted. Findings were initially categorized into "major" or "minor" depending on if they were mentioned in the report impression/conclusion. Any major thoracic pathology was termed "significant" if there was a new diagnosis/patient intervention/investigation and a change in patient management.Results: Of the 150 scans included in the study, 97 (65%) had at least one thoracic finding. These findings included 24 scans (16%) with major findings and 73 scans (48%) with minor findings. In 13 scans (9%), the findings were significant and resulted in a delay (n 5 11) or cancellation (n 5 2) of AAA repair. Conclusion: Pre-procedural EC-CECT helps to identify significant intrathoracic findings in patients with AAA, which can have a major impact on AAA repair. This study supports the routine use of pre-procedural EC-CECT in planning AAA repair. Advances in knowledge: This study describes the prevalence of significant thoracic pathology, which can impact on AAA repair. This information could potentially change the pre-procedure imaging protocol for patients with AAA.

“…These findings are in accordance with the study of McKenna et al [12], which demonstrated the importance of reviewing the scout sequences that identified the ECF most frequently. Another recent study identified SSFP scout images and axial T1-weighted thoracic fast spin-echo images as being most useful, detecting 95% of all noncardiac findings [13], whereas Atalay et al found axial bright-blood and dark-blood imaging to have the highest detection rates for ECF [15]. There are several limitations to this study.…”

“…These two modalities are difficult to compare as MRI has lower spatial resolution, meaning that the pickup of smaller lesions is more challenging. 2 One study compared the two in the same patient cohort and found a prevalence of 5% when CT was carried out and 2% on MRI. 4 Despite this study being carried out on an HIV-positive cohort we found a lower prevalence in this study compared to studies in the general population.…”

“…However, it is noteworthy that this study was carried out on well, asymptomatic patients for research purposes, whereas six out of the seven previously published studies have looked for CSECFs in patients having clinically indicated MRI scans. 2,3,[5][6][7][8] In some instances these patients were intubated, which would increase the chance of finding pathology such as atelectasis, pleural effusions and pneumonias which were often the most common findings. Dewey et al 4 found a prevalence of 2% CSECFs in a research group of older patients, mean age 63 years.…”

Clinically significant extra-cardiac findings in asymptomatic HIV-positive men undergoing cardiac magnetic resonance imaging

Increased research-based imaging has led to an increase in clinically significant extra-cardiac findings. HIV patients are at increased risk of having polypathology at a younger age; therefore, it may be hypothesised that they would have more incidental findings on imaging. We reviewed the magnetic resonance imaging results of 169 HIV-positive and 40 HIV-negative, clinically well volunteers undergoing cardiac magnetic resonance imaging scanning to assess the prevalence of subclinical cardiac pathology. This sub-study assessed the prevalence of clinically significant extra-cardiac findings. Associated risk factors were assessed and clinical follow-up and outcome were ascertained. Of the HIV-positive study group, 12/169 (7.1%) vs. 1/40 (2.5%) control patients had a clinically significant extra-cardiac finding which warranted further radiological or clinical intervention (p = 0.28). A total of three out of 169 (1.1%) were highly clinically significant findings. On logistic regression analysis, age was the only significant contributing factor (p = 0.049); no HIV-associated factors were found to be significant. The prevalence of clinically significant extra-cardiac findings of 7.1% in this HIV-positive cohort is comparable to the prevalence found in previous studies carried out on an older, sicker general population. This highlights the need for planning for unexpected outcomes and also the high rate of clinically significant findings in a seemingly well HIV-positive population.

The Prevalence and Clinical Significance of Noncardiac Findings on Cardiac MRI

Abstract: NCFs are commonly encountered on cardiac MRI studies, many of which are clinically relevant. Proper recognition of NCFs is critical to the comprehensive management of patients referred for cardiac MRI.
