To evaluate the clinical value and impact of radiological imaging in published medial case reports. ⋯ • Radiology was the most important specialty for finding the final diagnosis. • CT was the most successful problem-solving imaging modality followed by MRI. • MRI and CT had the best solution rates of more than 30%.

Structural connectivity analysis is an ideal tool to study connections in brain malformations. We aimed to characterize the topological network measures and study sub-networks in children with agenesis of the corpus callosum (AgCC). We hypothesized a more segregated structural network in children with AgCC. ⋯ • The structural connectivity analysis quantifies white-matter networks within the brain • In callosal agenesis there is reduced global and increased local connectivity • In callosal agenesis, alternative decussating pathways are used for interhemispheric connectivity.

The objective is to use multidetector computed tomography (MDCT) to differentiate phytobezoar impaction and small-bowel faeces in patients with small-bowel obstruction (SBO). ⋯ • MDCT examination helps to differentiate phytobezoar and small-bowel faeces. • A higher grade of obstruction is commonly associated with phytobezoar impaction. • Mesenteric fatty stranding and intraperitoneal fluid are frequently associated with small-bowel faeces. • Quantitative measurement of the obstructed bowel adds the diagnostic accuracy.

To evaluate the influence of scan duration on pharmacokinetic parameters and their performance in differentiating benign from malignant breast lesions. ⋯ • Scan duration of DCE-MRI breast imaging has a significant impact on pharmacokinetic parameters • A scan duration of less than 2 min results in spurious parameter estimates • The initial 2 min are important for both benign and malignant lesions • In malignant lesions the impact extends to 4 - 6 min • The differentiation ability of parameters may not be affected by scan duration.

Observational Study
Percutaneous consolidation of loosened spine arthrodesis under CT and fluoroscopy guidance by radiologists: a new useful technique.
The objective was to evaluate percutaneous computed tomography (CT) and fluoroscopy-guided injection of bone cement for consolidation of loosened posterior arthrodesis performed by radiologists. ⋯ • PLIF is one of the surgical techniques for spinal arthrodesis. • Treatment indications are degenerative disease or instability following trauma, tumour, or infection. • Screw loosening is a frequent complication that can occur after surgery. • Percutaneous facet consolidation under dual guidance seems to be a feasible technique. • The procedure is performed under local anaesthesia using a minimally invasive approach.
