Quantitative susceptibility mapping shows lower brain iron content in children with childhood epilepsy with centrotemporal spikes
ConclusionsThis study suggests that the potential iron deficiency in certain brain regions is associated with CECTS, which might be helpful for further illumination of potential pathogenesis mechanism of CECTS. (Source: Japanese Journal of Radiology)

Applications of artificial intelligence in magnetic resonance imaging of primary pediatric cancers: a scoping review and CLAIM score assessment
ConclusionThe literature surrounding AI applications of MR imaging in pediatric cancers is limited. The existing literature shows moderate adherence to CLAIM guidelines, suggesting that better adherence is required for future studies. (Source: Japanese Journal of Radiology)

Percutaneous computed tomography-guided core needle biopsy can be used to histologically confirm the clinical features and long-term prognosis of pulmonary neuroendocrine neoplasms
ConclusionPNENs may be pathologically diagnosed using PCT-CNB. While differential diagnoses between LCNEC and SCLC are problematic in some patients, a HGNEC-NOS diagnosis was ascribed and PCT-CNB samples were shown to predict NEN OS rates. (Source: Japanese Journal of Radiology)

Colonic involvement in inflammatory bowel diseases: spotlight on the role of magnetic resonance enterography
AbstractThe large bowel can be affected by inflammatory bowel diseases, namely ulcerative colitis and Crohn ’s disease, with the latter occurring either as a unique localization or in conjunction with simultaneous ileal involvement. The differential diagnosis among these conditions is challenging and relies on clinical symptoms, laboratory tests and endoscopy with biopsy. However, as these features can overlap, a conclusive diagnosis is not always achievable, and the underlying cause remains indeterminate. Currently, endoscopy is the reference standard for colonic assessment, although its invasiveness limits its use and ...

Imaging findings of juvenile idiopathic arthritis and autoinflammatory diseases in children
AbstractJuvenile idiopathic arthritis (JIA) is a collective term for pediatric inflammatory arthritis of unknown etiology, which presents diverse clinical and imaging findings. The pathogenesis is complex; however, most cases stem from an autoimmune mechanism. Herein we provide a short review of imaging findings of JIA. Imaging assessment begins with plain radiography demonstrating joint swelling, periarticular osteopenia, and juxtaarticular bone erosion. Bone erosion occurs later in JIA. Instead, aberrant epimetaphyseal growth often gives the first clue to the diagnosis. US and MRI can demonstrate the details of the synov...

Construction of prediction model for KRAS mutation status of colorectal cancer based on CT radiomics
ConclusionThe clinical –radiomics fusion model, which combines the clinical and DP radiomics model, has the best predictive performance for predicting the mutation status ofKRAS in CRC, and the constructed model has been effectively verified by an internal validation cohort.
