Summary: DCBE is effective for providing an overview of the colon and detecting cecal nodules, but its accuracy may vary depending on the operator. REU accurately measures the distance between the rectosigmoid nodule and the anal verge, while MDCT-e is accurate in diagnosing intestinal endometriosis and assessing its characteristics. CTC performs well in diagnosing rectosigmoid endometriosis.

Summary: This study assessed the attenuation errors and image quality of abdominal virtual noncontrast (VNC) images acquired with photon-counting detector (PCD) CT compared to true noncontrast (TNC) images. The results showed consistent attenuation values in VNC images with small errors. Subjective image quality ratings were lower in VNC images, but the diagnostic quality still reached a good level.

Summary: ESGE/ESGAR strongly recommend computed tomographic colonography (CTC) for diagnosing colorectal neoplasia and suggest CTC or colon capsule endoscopy (CCE) if colonoscopy is incomplete. They provide guidelines on how to choose the appropriate imaging method in different scenarios.

Summary: The study evaluated the accuracy of preoperative CT in staging colonic diverticulitis and found that an increase in visceral obesity significantly improves the accuracy of CT. However, water enema does not have a diagnostic benefit.

Summary: Photon-counting computed tomography (PCCT) uses new detector technology to provide additional information compared to current CT and MR technologies. This review focuses on PCCT of the abdomen and its applications. It discusses the requirements and challenges for successful abdominal PCCT acquisition and highlights recent developments and protocols tested in clinical settings. PCCT has applications in imaging cystic lesions, identifying sources of bleeding, and staging cancers. It has the potential to advance beyond disease detection to quantitative staging and treatment response measurement.

Summary: Dual-energy CT (DECT) has advantages over conventional single-energy CT (SECT) in evaluating gastrointestinal diseases. Energy-and material-specific DECT image reconstructions can help improve lesion detection and disease characterization.

Summary: COVID-19 is a systemic disease with specific tropism for the vascular system, mainly affecting the lungs but can also involve other organs with variable clinical manifestations. The abdominal radiological findings in COVID-19 are nonspecific, but imaging modalities such as ultrasound and computed tomography are helpful for diagnosis and management of patients with abdominal symptoms.

Summary: Non-operative management of patients with Hinchey Ia acute diverticulitis and isolated pericolic air bubbles is feasible and safe, with a success rate of 94.9%. Only 1.2% of patients required percutaneous drainage for abscess formation, supporting the justification for conservative initial treatment in this group of patients.

Summary: The study found that in T1-CRC, the horizontal and vertical rigidities observed in barium enema examination are correlated with SM invasion depth. Horizontal rigidity may predict lympho-vascular invasion, aiding in therapeutic decision-making.

Summary: The advancement of technology has led to the development of different CT scanners for dual-energy computed tomography (DECT). One recent detector-based technology allows for data collection from different energy levels, enabling efficient material decomposition. Through post-processing techniques, these scanners can generate various conventional and virtual images. A review of the clinical application of DECT, focusing on its usefulness in gastrointestinal imaging, is necessary due to the increasing number of published studies.

Summary: This study retrospectively analyzed emergency ultrasound and CT images of patients with anisakiasis to evaluate the frequency of various signs according to the location of gastrointestinal tract involvement. The results showed that the most common CT findings in gastric cases were wall stratification and thickening, fat stranding, and ascitic fluid, while in intestinal cases, wall thickening, fat edema, and vessel engorgement were frequently observed. These different radiological signs suggest the inclusion of anisakiasis in the differential diagnosis of acute abdomen.

Summary: Gastrointestinal (GI) bleeding is a common and potentially life-threatening medical condition that often requires multidisciplinary collaboration for proper diagnosis and management. CT imaging plays a vital role in identifying the location and cause of bleeding, but interpreting CT scans in patients with GI bleeding can be challenging for radiologists.

Summary: This is a case report of a 15-year-old male with rectal prolapse who underwent surgical intervention with polypropylene sutures. The surgery was successful and the patient experienced no recurrence of prolapse after 5 years. This case highlights the importance of surgical treatment for rectal prolapse.

Summary: There is a significant disparity between science and practice in CT radiation dose. To successfully implement low-dose CT practice, it is important to provide care providers with information and education on scientific discoveries, as well as concrete guidelines for addressing practical issues.

Summary: This study aimed to determine whether CT measurements of intraluminal contents and colon diameter were correlated with chronic constipation symptoms and stool consistency. Retrospective analysis of consecutive patients who underwent CSS, BSFS questionnaires, and abdominal CT showed significant correlations between CT findings and constipation symptoms and stool consistency.
