US-FNAB of pediatric thyroid nodules is feasible, allows diagnostic cytopathological evaluation, and correlates with surgical pathology results in resected nodules.

Image-guided percutaneous core needle biopsy of pediatric soft-tissue masses is safe, has a high diagnostic rate, and provides sufficient tissue for ancillary testing.

Hepatocellular carcinoma is the third most common cause of cancer-related death. In the past few years, staging systems have been developed that enable patients to be stratified into treatment algorithms in a multidisciplinary setting. Several of these treatments involve minimally invasive image-guided therapy that can be performed by radiologists.

The theoretical advantage of the MRI-LAARP is placing the neorectum through the entire sphincter complex without transecting the muscle. Follow-up of these patients shows good short-term results; however, long-term follow-up will be needed to best assess sphincter and bowel function.
