Inflammatory bowel disease (IBD) refers to a group of chronic, relapsing conditions of the gastrointestinal tract characterized by underlying inflammation. The two major subtypes of IBD are Crohn’s disease (CD) and ulcerative colitis (UC), both of which involve persistent inflammation of the gastrointestinal tract [1,2]. While both conditions share this chronic inflammatory nature, they differ significantly in anatomical distribution and pathophysiology: UC is restricted to the colon and rectum,…

Value of rectal MRI prior to endoscopic submucosal dissection (ESD): an exploratory study
Endoscopic submucosal dissection (ESD) is an advanced endoscopic technique initially created in Japan to overcome the limitations of endoscopic mucosal resection (EMR) and was used primarily for early gastric cancer [1,2]. It has been applied relatively recently to the 10–15 % of colorectal polyps that are not able to be removed at routine colonoscopy by cold forceps or snare polypectomy [2], such as large flat and sessile polyps [3], sometimes called “complex polyps” [2]. EMR and ESD provide an…

Association between free water and longitudinal dynamics of recent small subcortical infarcts: a study based on diffusion tensor imaging
The mechanisms underlying the different morphological evolution of recent small subcortical infarcts (RSSIs)—ranging from cavitation to complete disappearance—remain incompletely understood. Free water (FW), derived from diffusion tensor image, has emerged as a sensitive marker reflecting various pathophysiological processes that may influence RSSI evolution. This study aimed to investigate whether baseline FW measures and their longitudinal changes are associated with the morphological evolutio…

Optimal post-contrast timing for photon-counting CT-based myocardial extracellular volume quantification in a swine model: Cardiac magnetic resonance as the reference
Extracellular volume (ECV) fraction refers to the proportion of extracellular matrix in the whole myocardium. Elevated ECV values are observed in conditions such as myocardial infarction, cardiac amyloidosis, myocarditis, and hypertrophic cardiomyopathy. ECV mapping can assist in differentiating between these and other diseases, as well as providing prognostic information[1–5]. Cardiac magnetic resonance (CMR) imaging has been the non-invasive gold standard for ECV assessment due to its high acc…

Deep learning-based detection of ascending aortic dilatation on chest radiographs: A diagnostic study
Ascending aortic dilatation (AAD) is a potentially life-threatening condition that often remains undetected until serious complications arise [1,2]. As the diameter of the ascending aorta increases the risk of rupture increases [3], but most ascending aortic aneurysms are asymptomatic at the time of diagnosis [2] until devastating consequences [4] occur

Implementation of generic and individual justification: Findings from a survey under the IAEA technical cooperation programme in Europe and Central Asia
Medical uses of ionizing radiation are among the longest established applications of ionizing radiation and represent by far the largest and increasing contribution to the exposure of the human population from man-made radiation sources [1]. They bring considerable health benefits and are thus considered justified in general (ICRP first level [2]). As medical exposure is increasing, the principles of justification and optimization should be reinforced. Proper justification not only ensures that …
