Comparative StudyF-18 FDG-PET imaging and correlation with CT in staging and follow-up of pediatric lymphomas.
We hypothesized that F-18 FDG-PET could be a useful, functional imaging modality for assessing the initial staging, response to therapy and follow-up of children diagnosed with lymphoma. ⋯ F-18 FDG-PET imaging is a useful technique for the staging and follow-up of pediatric patients with lymphoma.

Percutaneous US-guided biopsies of peripheral pulmonary lesions in children.
A wide variety of diseases in children can present with peripheral lung lesions. Minimally invasive percutaneous techniques are preferred diagnostic tools when thoracoscopic resection is not indicated. Significant improvements in US resolution have increased the range of its applications for many diagnostic and therapeutic purposes. ⋯ This small retrospective study suggests that US-guided lung biopsies are a safe and adequate method to sample peripheral pulmonary lesions in children, with a high rate of technical success and low morbidity, even for lesions with a small pleural surface (<5 mm).

Comparison of lingual tonsil size as depicted on MR imaging between children with obstructive sleep apnea despite previous tonsillectomy and adenoidectomy and normal controls.
Cine MRI has become a useful tool in the evaluation of patients with persistent obstructive sleep apnea (OSA) despite previous surgical intervention and in patients with underlying conditions that render them susceptible to multilevel airway obstruction. Findings on cine MRI studies have also increased our understanding of the mechanisms and anatomic causes of OSA in children. ⋯ Enlargement of the lingual tonsils is relatively common in children with persistent obstructive sleep apnea after palatine tonsillectomy and adenoidectomy. This is particularly true in patients with Down syndrome.
