The 320-row multidetector computed tomography (MDCT) enables the scanning of a maximum length of 160 mm by volume scanning (VS). Dynamic volume scanning (DVS) with MDCT enables the development of a 4D dynamic image.
The 3D findings of tracheobronchial imaging in children who cannot control their breathing fail to reveal the phase of breathing in which the image was taken, which affects the accuracy of the diagnosis of tracheobronchial stenosis. Imaging by 4D-DVS enables the accurate observation of the tracheal dynamics in association with the respiratory kinetics, thus revealing the mechanism of the former. Furthermore, 4D-DVS would enable the imaging of the cardiac blood vessels by a contrast study simultaneously with the imaging of the stenosed area.
We assessed the efficacy of the 4D-DVS imaging technique in the diagnosis of pediatric tracheobronchial stenosis. Read More

Palpable masses of the scalp and neck are a common indication for imaging in children. Ultrasound serves as the first-line modality with high spatial resolution and the ability to assess vascularity without the need for ionizing radiation or sedation/anesthesia, rendering it very effective at differentiating between the many possible pathologies. This educational exhibit will outline the appropriate scanning technique, followed by a case-based review of the ultrasound appearance of some of the most common entities presenting as palpable neck and scalp masses in the pediatric population. Pathologies covered in this review include thyroglossal duct cysts, branchial cleft cysts, ectopic thymus, fibromatosis, epidermal inclusion cysts, pilar cysts, dermoid/epidermoid cysts, ranula, vascular malformations, and pseudomasses such as parotitis. This exhibit will discuss atypical features that may require further assessment with additional modalities. Lastly, relevant ultrasound anatomy, including midline neck and floor-of-mouth structures, will be reviewed as it pertains to surgical planning. Read More
