The aim of this paper is to identify the boards in which radiologists participate and to detect the needs, problems and opportunities that these boards pose for our specialty.</div></div><div><h3>Methods and materials</h3><div>The Spanish Society of Medical Radiology (SERAM) conducted an ad-hoc survey that was distributed among members and through social networks. The results were analysed with Stata® v14.2 (StataCorp, Texas, USA).</div></div><div><h3>Results</h3><div>Between 15 November 2022 and 24 December 2022, we received 743 anonymous responses with 93.7% coming from SERAM members (642 radiologists and 101 radiology trainees). Among the specialists, 82.7% regularly participate in one or more boards (92.5% oncology/50.7% non-oncology/43.3% both), which implies two or more meetings per week for 41.6% of the respondents.</div><div>Both radiologists who regularly participate in boards and those who do not, are very positive about this aspect of professional activity and agree on its benefits. However, the specialists who do participate, lack enough allocated time and information to prepare cases prior to the meeting. Although attendance is often recorded (69.7%), it is generally not included in the work plan (20.5% of physicians and 30.8% of middle managers, <em>p</em> = 0.028).</div><div>Regarding operational functioning, according to 46.9% of respondents there is no record of imaging tests reviewed, and the handling of discrepancies within radiology departments is poor (written recommendations and review sessions are only available to 14.3% and 7.7% of respondents respectively).</div></div><div><h3>Conclusions</h3><div>The radiologists surveyed report the high impact of multidisciplinary committees on their workload and clinical decisions. They mention a number of problems, some of which are specific to radiology, which can undermine efficiency and safety. These include work organisation, lack of time and problems of accessibility and the recording of imaging tests and other medical record data.</div></div>","PeriodicalId":94185,"journal":{"name":"Radiologia","volume":"66 6","pages":"Pages 526-541"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142824951","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study of the gastrointestinal tract using MRI has become feasible due to the emergence of ultrafast sequences with higher spatial resolution and phased-array coils enabling wider fields of view. However, to ensure the quality of the examination, it is essential to have prior preparation with oral or rectal contrast to distend the lumen and improve the definition of the intestinal wall. These contrast agents can be positive, negative or biphasic, depending on the signal intensity they induce in the intestinal lumen. Most commonly used biphasic contrasts agents behave as hyperintense in T2 and hypointense in T1. Achieving a “black” intestinal lumen in 3D T1-weighted sequences with intravenous contrast injection is crucial for mucosal assessment and parietal enhancement. Although more cost-effective and accessible, biphasic agents like PEG and mannitol are relatively discomforting for patients. While negative agents are preferred, they are currently unavailable. The purpose of this article is to review the different types of contrast agents mentioned in the literature and their application in intestinal resonance, analyzing the effects they generate on the image, their possible indications and associated limitations.</div></div>","PeriodicalId":94185,"journal":{"name":"Radiologia","volume":"66 ","pages":"Pages S89-S97"},"PeriodicalIF":0.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142704590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article we define PC-AKI and its risk factors, propose a prophylaxis protocol and respond to the most common doubts that arise around prophylaxis. We also update the fasting guidelines to be followed prior to contrast testing. In general, fasting of solids is not necessary before injecting iodinated contrast or gadolinium except in tests in which it is necessary to specifically study the upper digestive tract and bile duct. Even in these cases, fasting clear liquids is not required, which is of great help for oral hydration and for reducing the incidence of PC-AKI.</div></div>","PeriodicalId":94185,"journal":{"name":"Radiologia","volume":"66 ","pages":"Pages S118-S123"},"PeriodicalIF":0.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142704592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
