In recent years, computerized tomography (CT) has become one of the most important imaging modalities in evaluation of patients with acute gastrointestinal disorders. Its role, diagnostic accuracy, indications, and limitations in some of the most commonly encountered acute abdominal conditions are succinctly presented and reviewed. CT should not be used indiscriminantly, but is best considered a valuable primary or complimentary diagnostic tool in critically ill patients. Its selective use in a variety of emergency abdominal diseases will significantly improve accuracy of clinical diagnoses, leading to a prompt and adequate medical or surgical management.

Right coronary sinus of Valsalva pseudoaneurysm after a motorcycle accident: A case report.
Medicine (Baltimore)
January 2025
Department of Radiology, West China Hospital, Sichuan University, Chengdu, Sichuan, China.
Rationale: Traumatic pseudoaneurysm of the sinus of Valsalva (PSV) is a rare but life-threatening condition, often resulting from blunt chest trauma. Rapid progress and a high risk of rupture highlight the importance of prompt diagnosis and intervention. We present a case of a rare pseudoaneurysm linked to the right coronary sinus after blunt chest trauma.

Department of Medical Imaging, Jincheng People's Hospital, Shanxi, China.
Rationale: Thrombus is the most common occupying lesion in the cardiac chambers, it is often distinguished from cardiac neoplastic occupations. Among them, the most common is cardiac myxoma, whose imaging manifestations are often confused with thrombus. However, the 2 types of lesions have different therapeutic strategies and are both potentially high-risk sources of embolism, so early differentiation between intracardiac thrombus and cardiac tumor is essential.

Department of Radiology, Guang'anmen Hospital, China Academy of Chinese Medical Sciences, Beijing, China.
To evaluate the diagnostic accuracy of artificial intelligence (AI) assisted radiologists and standard double-reading in real-world clinical settings for rib fractures (RFs) detection on CT images. This study included 243 consecutive chest trauma patients (mean age, 58.1 years; female, 166) with rib CT scans.

Cancer Rep (Hoboken)
January 2025
Department of Thoracic Surgery, Affiliated Hospital of Zunyi Medical College, Zunyi, People's Republic of China.
Background: Neuroendocrine tumors of the thymus (NETT) are rare and malignant tumors that arise in the anterior mediastinum. These tumors can exhibit aggressive behavior and may involve surrounding critical structures, such as the superior vena cava. This case contributes to the literature by presenting a recurrent thymic carcinoma with invasion of major blood vessels, including the superior vena cava, and the complexities involved in its surgical management.

CNS Neurosci Ther
January 2025
Department of Radiology, Affiliated Hangzhou First People's Hospital, Westlake University School of Medicine, Hangzhou, China.
Aims: To develop a transformer-based generative adversarial network (trans-GAN) that can generate synthetic material decomposition images from single-energy CT (SECT) for real-time detection of intracranial hemorrhage (ICH) after endovascular thrombectomy.
Materials: We retrospectively collected data from two hospitals, consisting of 237 dual-energy CT (DECT) scans, including matched iodine overlay maps, virtual noncontrast, and simulated SECT images. These scans were randomly divided into a training set (n = 190) and an internal validation set (n = 47) in a 4:1 ratio based on the proportion of ICH.
