Percutaneous Radiofrequency Ablation for the Treatment of Osteoid Osteoma in Children and Adults: A Comparative Analysis in 92 Patients.

Purpose: To compare technical success, complications, and long-term clinical success following radiofrequency ablation of osteoid osteomas in pediatric and adult patients.

Materials And Methods: Ninety-two patients underwent percutaneous computed tomography-guided radiofrequency ablation for osteoid osteomas including 54 pediatric (mean age 12.9 years) and 38 adult (mean age 24.

Chest Radiograph Measurement Technique Facilitates Accurate Bedside Peripherally Inserted Central Catheter Placement in Children.

Purpose: To report the chest radiograph measurement technique for placing bedside peripherally inserted central catheters (PICCs).

Materials And Methods: Two hundred and thirty-two consecutive pediatric patients, mean age of 56.3 months (range: 0-203 months), underwent PICC placement from January 2015 to May 2017 (28 months) with a total of 232 PICCs placed.

Magnetic-resonance-guided biopsy of focal liver lesions.

Image-guided biopsy techniques are widely used in clinical practice. Commonly used methods employ either ultrasound (US) or computed tomography (CT) for image guidance. In certain patients, US or CT guidance may be suboptimal, or even impossible, because of artifacts, suboptimal lesion visualization, or both.

Image-guided percutaneous core needle biopsy of soft-tissue masses in the pediatric population.

Background: A paucity of literature describes the use of imaged-guided percutaneous core needle biopsy for the diagnosis and characterization of pediatric soft-tissue masses and lesions.

Objective: To retrospectively determine whether image-guided percutaneous core needle biopsy is adequate for diagnosing and characterizing benign and malignant pediatric soft-tissue masses and lesions.

Materials And Methods: We identified children (≤18 years old) who underwent US- or CT-guided percutaneous core needle biopsy of a soft-tissue mass or other lesion between January 2012 and March 2014.

Ultrasound-guided fine-needle aspiration biopsy of pediatric thyroid nodules.

Background: The role of US-guided fine-needle aspiration biopsy (US-FNAB) of thyroid nodules is not well-established in children.

Objective: To retrospectively assess the utility of US-FNAB of pediatric thyroid nodules.

Materials And Methods: We reviewed Department of Radiology records to identify children who underwent US-FNAB of the thyroid between 2005 and 2013.
