    Abstract Purpose: To investigate the degree of perceived publication pressure in medical imaging.
    Method: Corresponding authors who published an article in one of the top 12 general radiology journals were invited to complete a survey about publication pressure. The revised Publication Pressure Questionnaire (PPQr) was used. Higher PPQr scores (5-point Likert scale) indicate a more negative view towards the various domains of publication pressure.
    Results: 203 corresponding authors participated. Median PPQr scores in the domains "publication stress", "publication attitude", and "publication resources" were 3.33, 3.50, and 3.67, respectively. Age 25-34 years (β coefficient 0.366, P = 0.047), female gender (β coefficient 0.293, P = 0.020), and 5-10 years of research experience (β coefficient 0.370, P = 0.033) were associated with a higher level of perceived publication stress, whereas age ≥ 65 years was negatively associated with perceived publication stress (β coefficient -0.846, P < 0.001). Age 55-64 years and age > 65 years were associated with a more positive view towards the publication climate (β coefficients -0.391 and -0.663, P = 0.018 and P = 0.002, respectively). Age 45-54 years was associated with a perception of fewer factors available to alleviate publication pressure (β coefficient 0.301, P = 0.014), whereas age 25-34 years was associated with a perception of more factors available to alleviate publication pressure (β coefficient -0.352, P = 0.012).
    Conclusion: Perceived publication pressure among medical imaging researchers appears to be appreciable and is associated with several (academic) demographics.

    Abstract Background Previous studies have shown an increase in the number of authors on radiologic articles between 1950 and 2013, but the cause is unclear. Purpose To determine whether authorship rate in radiologic and general medical literature has continued to increase and to assess study variables associated with increased author numbers. Materials and Methods PubMed/Medline was searched for articles published between January 1998 and October 2022 in general radiology and general medical journals with the top five highest current impact factors. Generalized linear regression analysis was used to calculate adjusted incidence rate ratios (IRRs) for the numbers of authors. Wald tests assessed the associations between study variables and the numbers of authors per article. Combined mixed-effects regression analysis was performed to compare general medicine and radiology journals. Results There were 3381 original radiologic research articles that were analyzed. Authorship rate increased between 1998 (median, six authors; IQR, 4) and 2022 (median, 11 authors; IQR, 8). Later publication year was associated with more authors per article (IRR, 1.02; 95% CI: 1.01, 1.02;

    Abstract Background Editorial board members may be biased due to conflicts of interest (COIs). Purpose To investigate the frequency and amount of payments from industry to editorial board members of imaging-related journals and whether they are in agreement with the disclosure status as provided by the journal. Materials and Methods Editorial board members of 15 U.S.-based imaging-related journals who were listed in the Open Payments database (OPD) were included. Payments from industry to editorial board members in the year 2020 were extracted from the OPD and compared with publicly available COI disclosure data as provided by the journals. The Kruskal-Wallis test was used for statistical analysis. Results A total of 519 editorial board members were included, of whom 214 (41%) received industry payment and 305 (59%) did not. Payments to editorial board members by the industry ranged from $12.63 to $404 625.47 (median, $2397.48). Most payments from industry (59%) were ascribed to consulting.

    Abstract Objective: To investigate the proportion of published imaging studies relative to incidence and mortality rate per cancer type.
    Methods: From a random sample of 2500 articles published in 2019 by the top 25 imaging-related journals, we included cancer imaging studies. The publication-to-incidence and publication-to-mortality ratios (defined as the publication rate divided by the proportional incidence and mortality rate, respectively) were calculated per cancer type. Ratios >1 indicate a higher publication rate compared to the relative incidence or mortality rate of a specific cancer. Ratios <1 indicate a lower publication rate compared to the relative incidence or mortality rate of a specific cancer.
    Results: 620 original cancer imaging studies were included. Female breast cancer (20.2%), prostate cancer (13.0%), liver cancer (12.9%), lung cancer (8.8%), and cancers in the central nervous system (8.1%) comprised the top 5 of cancers investigated. Cancers in the central nervous system and liver had publication-to-incidence ratios >2, whereas nonmelanoma of the skin, leukemia, stomach cancer, and laryngeal cancer had publication-to-incidence ratios <0.2. Cancers in the prostate, central nervous system, female breast, and kidney had publication-to-mortality ratios >2, whereas esophageal cancer, stomach cancer, laryngeal cancer, and leukemia had publication-to-mortality ratios <0.2.
    Conclusion: This overview of published cancer imaging research may be informative and useful to all stakeholders in the field of cancer imaging. The potential causes of disproportionality between the publication rate vs. incidence and mortality rates of some cancer types are multifactorial and need to be further elucidated.

    Abstract Rationale and objective: It is currently unknown how many publications in the medical imaging literature are retracted and for which reasons. The purpose of this study was to perform an updated analysis on retracted medical imaging publications using the Retraction Watch Database.
    Materials and methods: The Retraction Watch Database was searched for all retracted publications in the subject category "Radiology/Imaging" (no beginning date limit, search update until April 27, 2022). Reasons for retraction were extracted using standardized coding taxonomy. The number of citations per retracted publication was determined. Spearman's rho was used for statistical analysis.
    Results: 192 retractions, originally published between 1984 and 2021, were included. Most retractions originated from China (31.3%), the United States (12.5%), Japan (7.3%), and South Korea (6.3%). The number of retractions increased over the years, especially since 2000 (Spearman's rho=0.764, p <0.001). Delay between original publication and retraction ranged from 0 days to 14 years and 3 months (median of 11 months). Most common reasons for retraction were duplication of article (7.1%), plagiarism of article (6.8%), concerns/issues about data (5.4%), investigation by company/institution (4.5%), and forged authorship (4.0%). Scientific misconduct was deemed present in 107 of 192 retracted articles (55.7%). Retracted articles (of which 138 were listed in Web of Science) received a median of 2 citations (range 0-148, IQR 5).
    Conclusion: The number of retracted medical imaging publications continues to increase over time, which could indicate that more compromised research has either been published or discovered. Scientific misconduct was the main cause for retraction.

    Abstract Objective: To systematically review the diagnostic criteria and performance of MRI in detecting locally recurrent soft tissue sarcoma.
    Methods: Medline and Embase were searched for original studies on the diagnostic performance of MRI detecting locally recurrent soft tissue sarcoma. Study quality was assessed using QUADAS-2. Sensitivity and specificity were pooled using a bivariate random-effects model.
    Results: Ten studies were included. There was a high risk of bias with respect to patient selection in 2 studies and a high risk of bias with respect to flow and timing in 8 studies. The presence of a mass yielded a pooled sensitivity of 80.9% and a pooled specificity of 77.0%. Hyperintensity at T2-weighted imaging yielded a pooled sensitivity of 82.4% and a pooled specificity of 11.0%. Hypo- or isointensity at T1-weighted imaging yielded a pooled sensitivity of 82.0% and a pooled specificity of 14.3%. Contrast enhancement images yielded a pooled sensitivity of 95.9% and a pooled specificity of 12.3%. Low signal mass on the apparent diffusion coefficient (ADC) map yielded a pooled sensitivity of 67.5% and a pooled specificity of 95.3%. Early and rapid arterial phase enhancement at dynamic contrast-enhanced (DCE) MRI yielded a pooled sensitivity of 91.3% and a pooled specificity of 84.7%.
    Conclusion: The presence of a mass appears a useful criterion to diagnose locally recurrent soft tissue sarcoma. Signal characteristics at standard T2- and T1-weighted imaging and contrast enhancement seem less useful because they lack specificity. Functional MRI techniques, including DWI with ADC mapping and DCE, may help to make a correct diagnosis.
    Key points: • The presence of a mass at MRI appears useful to diagnose locally recurrent soft tissue sarcoma, because both sensitivity and specificity are fairly high. • Signal characteristics at standard T2- and T1-weighted sequences and contrast enhancement suffer from poor specificity. • DWI with ADC mapping and DCE may help to make a correct diagnosis, but further research is needed to better understand the value of these functional MRI techniques.
