Safety of non-ionic contrast media in CT examinations for out-patients: retrospective multicenter analysis of 473,482 patients
ConclusionThe use of NICM for out-patients is in general safe with a low ADR incidence. The type of contrast medium (iopromide) and the seasons (summer and autumn) were associated with a higher risk of acute ADRs. Late ADRs were more often observed with iodixanol.Clinical relevance statementIn comparison to in-patients, out-patients may be exposed to higher risk due to a lack of extensive risk screening, less nursing care, and higher throughput pressure. Safety data about NICM from a large population may complement guidelines and avoid ambiguity.Key Points•The incidence and risk factors for adverse events after using non...

Of editorial processes, AI models, and medical literature: the Magnetic Resonance Audiometry experiment
AbstractThe potential of artificial intelligence (AI) in the field of medical research is unquestionable. Nevertheless, the scientific community has raised several concerns about a possible fraudulent use of these tools that might be used to generate inaccurate or, in extreme cases, erroneous messages that could find their way into the literature. In this experiment, we asked a generative AI program to write a technical report on a non-existing Magnetic Resonance Imaging technique called Magnetic Resonance Audiometry, receiving in return a full seemingly technically sound report, substantiated by equations and references. ...

Ilio-femoral venous stenting for post-thrombotic syndrome in women of childbearing age: efficacy and impact of pregnancy —a multi-center study by the French Society of Cardiovascular Imaging
ConclusionIliofemoral venous stenting in women of childbearing age was an effective treatment for post-thrombotic syndrome, and it did not increase the risk for stent occlusion during pregnancy when accompanied by appropriate anticoagulation.Clinical relevance statementThis study demonstrates that pregnancy following iliofemoral venous stenting for post-thrombotic syndrome does not elevate the risk for stent occlusion.Key Points• The severity of post-thrombotic syndrome and the quality of life, as measured using the Villalta score and Chronic Venous Disease Quality of Life Questionnaire – version 20, respectively, show...

The validity of ultrasound and shear wave elastography to assess the quality of the rotator cuff
ConclusionSWE is not a valid method to measure the amount of FI or muscle atrophy in the SSP muscle. Therefore, SWE is not a suitable alternative for MRI in standard preoperative diagnostics in rotator cuff pathologies.Clinical relevance statementShear wave elastography should not be used in the diagnostics of rotator cuff pathologies.Key Points• There is a fair correlation between the Goutallier stage of the supraspinatus and infraspinatus muscle assessed on MRI and CT and visual assessment of fatty infiltration achieved on US.• Shear wave elastography is not a valid tool for the determination of the amount of fatty i...
