Special Issue Information

Dear Colleagues,

The abdominal organs play a crucial role in the human body, constituting several vital systems such as the digestive system, urinary system, and reproductive system, which are indispensable for maintaining the body's normal physiological functions. As an important diagnostic tool, radiological diagnosis is irreplaceable in the early detection, condition assessment, treatment plan formulation, and treatment effect monitoring of abdominal diseases. This Special Issue will collect the applications of radiological technologies (CT, MRI, PET/CT, etc.) in diagnosing and treating abdominal diseases. Additionally, we will focus on the advances of new technologies and processing tools, including multimodal imaging, radiomics, artificial intelligence, and machine learning. Original articles, reviews, and brief reports are welcome.

Background: Gallstone ileus is a rare cause of bowel obstruction, often presenting with nonspecific symptoms that delay diagnosis. This study assessed the diagnostic value of CT imaging and its correlation with histopathological findings in confirmed cases. Methods: A retrospective analysis of 14 patients with surgically confirmed gallstone ileus was performed. All underwent abdominal radiography, ultrasound, and CT. Imaging findings were evaluated for calcification type, impaction site, and fistula presence. Histopathology from surgical specimens was used for correlation. Relative risk (RR) and 95% confidence intervals (CIs) were calculated, with adjustments for small sample size. Results: Rim-calcified gallstones were the most common (50%) and significantly associated with chronic inflammation (RR 1.42, 95% CI: 1.05–1.93). Cholecystoduodenal fistulas were most frequent (57.1%), with a 92.8% imaging-pathology concordance. Ileal impaction (35.7%) was linked to increased risk of bowel necrosis (RR 2.0, 95% CI: 1.1–3.6). All stones were >3 cm; two patients had recurrence. No perioperative mortality occurred. Conclusions: CT imaging demonstrates high diagnostic accuracy and strong correlation with histopathological findings in gallstone ileus. Identifying calcification patterns and impaction sites aids early diagnosis and surgical planning. Full article
