Comparative Study
Accuracy of CT angiography in the assessment of the circle of Willis: comparison of volume-rendered images and digital subtraction angiography.
Computed tomography angiography (CTA) is increasingly used for non-invasive imaging of the cerebrovascular diseases. ⋯ CTA is highly accurate in the assessment of anatomical variations of the circle of Willis; however, its sensitivity is limited in depicting hypoplastic segments.

Wandering spleen is rare and is associated with a high incidence of splenic torsion and infarction. Presenting symptoms range from an asymptomatic, incidentally palpated abdominal mass to an acutely ill patient. Because wandering spleen is uncommon in the pediatric population, a heightened awareness of the condition is required for accurate diagnosis and appropriate management. We present a case of a 4-year-old girl who presented with acute abdomen and was surgically confirmed to have a wandering spleen with torsion and complete infarction.

Comparative Study
Evaluation of pneumonia in children: comparison of MRI with fast imaging sequences at 1.5T with chest radiographs.
Although there has been a study aimed at magnetic resonance imaging (MRI) evaluation of pneumonia in children at a low magnetic field (0.2T), there is no study which assessed the efficacy of MRI, particularly with fast imaging sequences at 1.5T, for evaluating pneumonia in children. ⋯ MRI with fast imaging sequences is comparable to chest radiographs for evaluating underlying pulmonary consolidation, bronchiectasis, necrosis/abscess, and pleural effusion often associated with pneumonia in children.
