To compare two- and three-dimensional (2D and 3D) ultrasound of the gallbladder in an adult cohort. In this observational, cross-sectional study, gallbladder volumes were measured using 2D and 3D ultrasound. Examinations were performed in the fasting state and at predefined time intervals after ingestion of a standardized nutritional drink. At each time point, measurements were performed twice using 2D and twice using 3D ultrasound. Volumes were calculated using the ellipsoid method for 2D ultrasound. For 3D, manual tracing was performed.

Foot foreign body injuries are prevalent among pediatric populations, posing diagnostic and management challenges. X-ray examination is the first choice used by emergency physicians for localization and removal of foreign objects but it has limited value when the foreign body is not radiopaque, leading to missed diagnoses of non-radiopaque foreign bodies, we recommend simultaneous use of point-of-care ultrasound (POCUS) to rule out foreign body in every case especially when history and clinical exam highly suggestive of foreign body. This case series highlights the diagnostic utility of X-ray and POCUS in the emergency department and its sensitivity in detecting radiopaque and as well radiolucent foreign objects.

Transesophageal echocardiography enables visualization of structures within the spinal canal, particularly in the upper thoracic and lower cervical regions, but its diagnostic performance and clinical roles remain unclear. To systematically review studies evaluating the ability of transesophageal echocardiography to depict spinal canal anatomy and its potential diagnostic, monitoring, and interventional applications.

Prostate cancer is the most prevalent non-cutaneous malignancy in men. Mucinous adenocarcinoma is a rare histological variant, accounting for less than 0.5% of cases. Its distinctive imaging and histopathological features present unique diagnostic challenges.

Congenital heart disease (CHD) is the most common congenital malformation. Most CHD cases are classified as major, which means they require immediate care in the postpartum period by pediatric cardiology and pediatric cardiac surgery teams, not least because they are a leading cause of perinatal mortality. Threedimensional (3D) ultrasound of the fetal heart allows accurate assessment of cardiac anatomy.

To identify anatomical variations in the cervical vagus nerve using ultrasonography and assess their relationship with age, sex, side, site, and proximity to the thyroid gland. A crosssectional observational study was conducted on 347 patients undergoing routine or clinically indicated neck ultrasonography.

Pneumothorax is a potentially life-threatening condition whose diagnosis can be challenging. Ultrasound chest examination is generally fast and user-friendly, but in non-expert hands or with uncooperative patients, it may still be difficult and time-consuming. Adding another tool to support the suspicion of pneumothorax might be useful, potentially enhancing the diagnostic accuracy of standard ultrasound chest examination.
