Upper gastrointestinal studies are used for the diagnosis of intestinal malrotation, and the configuration of the duodenum and position of the DJ flexure are used for diagnosis. There are various challenges associated with diagnosing malrotation on the AP view, and obtaining a lateral view is recommended for diagnosis. To be useful, the lateral view must be of adequate quality. In addition, radiologists must be aware of the normal appearance and configuration of duodenal variants such as duodenum redundum, on the lateral view, as misdiagnosis of these may lead to unnecessary surgery. We aim to determine the proportion of lateral views considered of adequate quality for diagnosis, as well as the prevalence of a not previously described sign, the 'descending stair' and its correspondence to a diagnosis of duodenum redundum.

Suspected airway compression in symptomatic children with Lymphobronchial Tuberculosis (LBTB) can be diagnosed using modern computed tomography (CT) assisted by coronal minimum intensity projection (MinIP) reconstructions. The accuracy of plain radiographs in detecting airway compression in children with TB has not been evaluated against an imaging gold standard in a dedicated manner. We aimed to compare frontal CXR against thick-slab angled coronal CT MinIP in identifying airway stenosis at ten specific sites and to determine the agreement between the modalities regarding the degree of stenosis.

Lymphobronchial TB (LBTB) in children refers to airway narrowing by tuberculous lymphadenopathy. Diagnosis is made invasively using flexible bronchoscopy or noninvasively with CT, which can include minimum intensity projection (MinIP) reconstructions. Our aim was to generate standardized coronal minimum intensity projection CT reconstructions and compare these with flexible bronchoscopy in children with LBTB. Read More

There is no standardized system for assessment of which pediatric tumors are amenable to partial nephrectomy – a surgery that is considered in pediatric patients with bilateral renal masses and those with predisposition syndromes. The RENAL Nephrometry score is the most widely used system to assess renal tumor complexity for surgical decision making in adults. We evaluated the RENAL Nephrometry score and imaging features that might predict perioperative clinical outcomes. Read More
