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

Despite the development of new methods for the detection of Vesico Urethral Reflux (VUR), Voiding Cystourethrography (VCUG) still plays an important role in pediatric uroradiology. However, the use seems to have changed over time. International guidelines exist and the main indication is the Ultrasonography (US) finding of hydronephrosis, indicating a high grade VUR or, in boys, to exclude Posterior Urethral Valve (PUV). VUR is a common condition found in 30-40 % of children with UTI. Our department performs VCUG according to the guidelines given by the ESUR subgroup for Pediatric Uroradiology. Haukeland University Hospital (HUS) serve a population of 300000 people. At the Section of Pediatric Radiology, we observed a decrease in the use of VCUG. We therefore did a systematic review of all VCUGs performed at our department during 2013 and 2014, focusing in detail on the age group 1 year or less. We aim to be true to the image gently policy, maintaining the ALARA principle, keeping the radiation doses as low as reasonably possible. Read More
