JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. Localized Hyperthermia with Iron Oxide–Doped Yttrium Microparticles: Steps toward Image-Guided Thermoradiotherapy in Liver Cancer

Andrew C. Gordon, BA , Robert J. Lewandowski, MD , Riad Salem, MD, MBA , Delbert E. Day, PhD, MS , Reed A. Omary, MD, MS , Andrew C. Larson, PhD

Purpose: To test whether iron oxide (IO)–containing yttrium aluminosilicate (YAS) microparticles (MPs) can generate localized therapeutic hyperthermia (≥ 43°C) when injected intratumorally in an animal model of liver cancer and whether MP distributions could be visualized with magnetic resonance (MR) imaging.

AMERICAN JOURNAL OF ROENTGENOLOGY. Applying the Society of Radiologists in Ultrasound Recommendations for Fine-Needle Aspiration of Thyroid Nodules: Effect on Workup and Malignancy Detection

Hasan A. Hobbs, Manisha Bahl, Rendon C. Nelson, James D. Eastwood, Ramon M. Esclamado and Jenny K. Hoang

OBJECTIVE. The Society of Radiologists in Ultrasound (SRU) recommendations on thyroid nodules are intended to “diagnose thyroid cancers that have reached clinical significance, while avoiding unnecessary tests and surgery in patients with benign nodules.” The aim of our study was to determine the proportion of thyroid nodules undergoing ultrasound-guided fine-needle aspiration (FNA) that do not meet SRU recommendations.
