The cardiac conundrum: a systematic review and bibliometric analysis of authorship in cardiac magnetic resonance imaging studies

AbstractPurposeWe aimed to assess the role of radiologists, cardiologists, and other medical and non-medical figures in cardiac magnetic resonance imaging (MRI) research in the last 34 years, focusing on first and last authorship, number of published studies, and journal impact factors (IF).MethodsArticles in the field of cardiac MRI were considered in this systematic review and retrospective bibliometric analysis. For included studies, the first and last authors were categorized as cardiologists, radiologists/nuclear medicine physicians, medical doctors (MD) with specialties in both cardiology and radiology/nuclear medicine, and other MD and non-MD. Differences in the number of papers published overall and by year and institution location for the first and last author category were assessed. Mean IF differences between author categories were also investigated.ResultsA total of 2053 articles were included in the final analysis. For the first authors (n = 2011), 52% were cardiologists, 22% radiologists/nuclear medicine physicians, 16% other MD, 10% other non-MD, and 1% both cardiologists and radiologists/nuclear medicine physicians. Similarly, the last authors (n = 2029) resulted 54% cardiologists, 22% radiologists/nuclear medicine physicians, 15% other MD, 8% other non-MD, and 2% both cardiologists and radiologists/nuclear medicine physicians. No significant differences due to institution location in the first and last authorship proportions were found. Average journal IF was...

In conclusion, the results of the ISCHEMIA trial are in good accordance with those of the MR-INFORM trial recently published in the New England Journal of Medicine, as the noninvasive management of a large proportion of patients with CAD was shown to be noninferior to current invasive strategies. Recent outcome data from trials may therefore have an impact on future guidelines to further reduce the execution of unnecessary left heart catheterizations.

Authors: Snyder LL, Knox SC, Smutny CJ Abstract Hip pain in adults is a common complaint. Secondary processes can often mask underlying conditions, prolonging the course to diagnosis and definitive treatment. In this case, a 74-year-old man presented to an outpatient clinic after 6 weeks of right hip pain that began upon initiation of a rehabilitation program following coronary artery bypass graft surgery. Various imaging and treatment modalities (including radiography, osteopathic manipulative treatment, injection of the greater trochanteric bursa, L2-3 paravertebral block, magnetic resonance imaging, and intra-ar...

Background: Device rupture is considered a major complication associated with breast implants. The U.S. Food and Drug Administration recommends magnetic resonance imaging (MRI) surveillance 3 years after implantation and then every 2 years, but adherence to these recommendations is poor. The authors identified current practice management for breast implant rupture surveillance by surveying practicing U.S. plastic surgeons. Methods: An online survey of all active members of the American Society of Plastic Surgeons was performed. Questions analyzed imaging practice patterns related to breast implants. Logistic regressio...

Conclusion: Choroidal ganglioneuroma is rare. To our knowledge, no bilateral cases have been described in the literature. Major clinical features include a rapid increase in axial length, diffuse choroidal thickening, hyper-reflectivity in the choroid on optical coherence tomography, and loss of choroidal vasculature on ICGA. The current report provides multimodal imaging of choroidal ganglioneuroma for the first time and can be valuable for early diagnosis. PMID: 32454990 [PubMed]

Authors: Uchida T, Togashi H, Kuroda Y, Yamashita A, Itoh N, Haga K, Sadahiro M, Kayama T Abstract Reactive oxygen species (ROS) such as superoxide, hydroxyl radical, and hydrogen peroxide play an important role in the maintenance of life. However, production of excessive ROS and/or deficiency of the antioxidant system lead to oxidative stress and cause a variety of diseases. In the present study, we used electron spin resonance (ESR) to detect ROS in vivo to clarify its roles in redox dynamics and organ damage. However, the limited permeability of microwaves and low anatomic resolution of ESR equipment made it dif...

Authors: Xu M, Qian P, Zheng J, Ge H, Muzic RF Abstract We propose a new method for fast organ classification and segmentation of abdominal magnetic resonance (MR) images. Magnetic resonance imaging (MRI) is a new type of high-tech imaging examination fashion in recent years. Recognition of specific target areas (organs) based on MR images is one of the key issues in computer-aided diagnosis of medical images. Artificial neural network technology has made significant progress in image processing based on the multimodal MR attributes of each pixel in MR images. However, with the generation of large-scale data, there...

Authors: Jiao H, Jiang X, Pang Z, Lin X, Huang Y, Li L Abstract Breast segmentation and mass detection in medical images are important for diagnosis and treatment follow-up. Automation of these challenging tasks can assist radiologists by reducing the high manual workload of breast cancer analysis. In this paper, deep convolutional neural networks (DCNN) were employed for breast segmentation and mass detection in dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). First, the region of the breasts was segmented from the remaining body parts by building a fully convolutional neural network based on U-Net+...

A large number of studies support the effectiveness of physical activity (PA) in SZ. The aims of this trial is to assess the effects of a remote, web-based adapted PA program (e-APA) compared to a health education program (e-HE) on brain plasticity in SZ and healthy volunteers (HV) and on psychiatric, neur...
