Background/Objectives: Thyroid nodules are commonly observed in neck ultrasonography. Most nodules are benign; hence, several nodules require biopsy to accurately identify the malignant ones. Numerous risk classification guidelines have been developed for thyroid nodules, varying in their indications for fine-needle aspiration biopsy (FNAB). The aim of this study is to evaluate the performances of three internationally recognized thyroid imaging reporting and data systems (TIRADS) for risk stratification of malignancy in comparison to one another. Methods: A total of 225 thyroid nodules with definitive FNAB cytology or histopathological diagnoses were included in this study. Various ultrasound (US) features were classified into categories based on three TIRADS editions. The guidelines were assessed regarding sensitivity, specificity, predictive values, and diagnostic accuracy to compare diagnostic value. Results: The American College of Radiology (ACR)-TIRADS demonstrated the best diagnostic accuracy (63.1%), the highest specificity (58.7%) and positive predictive value (36.3%), among three different TIRADS systems. Korean (K)-TIRADS exhibited the highest sensitivity (94.2%), negative predictive value (96.1%), and the most favorable negative likelihood ratio (0.13). The European (EU)-TIRADS had a sensitivity of 90.4%, specificity of 48.6%, and diagnostic accuracy of 58.2%, ranking between the other two guidelines across most parameters. Conclusions: The rigorous use of the guidelines established by each of the three TIRADS systems would have markedly reduced the number of FNABs performed. The comparison of the three guidelines in our study indicated that they are effective screening methods for identifying malignant thyroid nodules. Among them, K-TIRADS showed the most effective diagnostic performance in sensitivity, while ACR-TIRADS yielded the best specificity.

Ingestion of foreign bodies is a rare clinical problem in healthy adults. Less than 1% of cases need surgery due to perforation or obstruction. Here, we describe an unusual case of a wine-cork ingestion by a 54-year-old woman with a history of chronic alcohol consumption. Computed tomography (CT) of the abdomen and pelvis revealed foreign body (FB) in terminal ileum. The proximal part of the ileum was dilated due to obstruction. Laparotomy was performed, and the FB was removed without complications. Most ingested FBs spontaneously pass through the gastrointestinal tract. However, in rare instances, the FB can cause obstruction. In case of suspicion of serious complications such as obstruction and perforation, abdominopelvic CT should be used. The application of radiographic techniques in the identification of FBs and the assessment of potential complications plays a crucial role in expediting medical interventions for patients.

Coronary computed tomography angiography (CCTA) is valuable for assessing both coronary and incidental extracardiac findings. Recognizing non-cardiac causes of chest pain and dyspnea can improve diagnostic efficiency. This study aimed to assess the prevalence of extracardiac findings in patients with normal or non-obstructive CCTA and to determine whether these findings could account for their presenting symptoms, such as chest pain or exertional dyspnea. We retrospectively analyzed 358 patients who underwent coronary computed tomography angiography between January 2021 and December 2024 due to chest pain or dyspnea. Patients with obstructive coronary artery disease, congenital coronary anomalies, valvular disease, or acute coronary syndrome were excluded. Two experienced radiologists reviewed all scans for extracardiac abnormalities and evaluated their potential relationship with patient symptoms. Extracardiac findings were identified in 236 patients (65.9%), with vertebral degenerative changes (39.1%) being the most frequent, followed by atelectasis (14.8%) and emphysema (10.6%). Findings potentially explaining chest pain were noted in 56% of patients with this symptom, while 64% of those with exertional dyspnea had relevant extracardiac abnormalities. Female sex and older age were significantly associated with higher prevalence of extracardiac findings (p
