Small bowel radiology

Abstract

Purpose of review Recent advances in computed tomography (CT), ultrasound (US), magnetic resonance imaging (MRI), and nuclear radiology have improved the diagnosis and characterization of small bowel pathology. Our purpose is to highlight the current status and recent advances in multimodality noninvasive imaging of the small bowel. Recent findings CT and MR enterography are established techniques for small bowel evaluation. Dual-energy CT is a novel technique that has shown promise for the mesenteric ischemia and small bowel bleeding. Advanced US techniques and MRI sequences are being investigated to improve assessment of bowel inflammation, treatment response assessment, motility, and mural fibrosis. Novel radiotracers and scanner technologies have made molecular imaging the new reference standard for small bowel neuroendocrine tumors. Computational image analysis and artificial intelligence (AI) have the potential to augment physician expertise, reduce errors and variability in assessment of the small bowel on imaging. Summary Advances in translational imaging research coupled with progress in imaging technology have led to a wider adoption of cross-sectional imaging for the evaluation and management of small bowel entities. Ongoing developments in image acquisition and postprocessing techniques, molecular imaging and AI have the strongest potential to transform the care and outcomes of patients with small bowel diseases.

When It’s Not Pancreatitis, Don’t Brush It Off: A Case Report of Small Bowel Perforation Caused by a Grill Brush Bristle Masquerading As Pancreatitis

“…MRI has excellent soft tissue resolution [16]. Findings such as mural edema and severe inflammation can be evaluated on T2-weighted and diffusion-weighted images, respectively [17]. Magnetic resonance cholangiopancreatography is particularly important in the evaluation of the pancreas and biliary tract when initial images suggest a mimicker, like pancreatitis in our case.…”

“…Magnetic resonance cholangiopancreatography is particularly important in the evaluation of the pancreas and biliary tract when initial images suggest a mimicker, like pancreatitis in our case. Despite the higher cost and time needed for MRI, it is considered a less invasive localization method than endoscopic evaluation [17].…”

“…Поэтому при подозрении на развитие серьезных осложнений со стороны Научно-практическая ревматология. 2022;60(6):578-586 пищеварительной системы следует использовать объективные методы визуализации, такие как эндоскопия (ЭГДС, ФКС, ВКЭ), компьютерная томография (КТ), рентгенография и ультразвуковое исследование (УЗИ) [2,[50][51][52][53][54][55].…”

“…Более высокую диагностическую ценность имеет КТ, которая позволяет диагностировать и документировать ранние изменения пищеварительной системы -в частности, утолщение СО и отек подслизистого слоя тонкой кишки при энтерите, воспаление брюшины, признаки мезентериального тромбоза, ранние признаки панкреонекроза и холангита и др. [53].…”

“…Рентгенологические методы с использованием контраста позволяют выявлять нарушения моторики, проходимости, участки патологического расширения и сужения ЖКТ и представляют значительную ценность для подтверждения функциональных проблем (в частности дисфагии, халазии кардии, декомпенсации стриктур пищевода, привратника и кишечника и др.) [2,53,54].…”
