PET protocols from head to toe
SAN DIEGO - Patient preparation and image acquisition techniques can maximize the benefit of using FDG-PET for tumor diagnosis and staging. At the University of Texas, M.D. Anderson Cancer Center in Houston, the modality has been used to stage or identify tumors as well as to distinguish recurrence from post-treatment changes and to monitor response to therapy.

Could elastography replace conventional ultrasound-guided FNAC?
By Amerigo Allegretto
Strain elastography does not have additional benefits over conventional elastography-guided FNAC for diagnosing malignancy in thyroid nodules.
October 15, 2024
Images depict a 43-year-old woman with a solitary left-sided thyroid nodule classified at gray-scale ultrasound as category U3, upgraded to category U4 at strain elastography, and classified as category Thy4 at cytopathologic examination. Subsequent surgical histopathologic examination confirmed papillary cell carcinoma. (A) Longitudinal view of the left thyroid lobe demonstrates the low reflective nodule (between arrows) measuring 13 × 12 × 11 mm (not shown) and with a halo. (B) A longitudinal image with side-by-side visualization of the nodule (arrow) at gray scale (left) and strain elastography (right). The nodule is predominantly blue, indicating increased stiffness. (C) A longitudinal view shows the needle (arrows) within the stiffer aspect of the nodule for cytology sampling. U and Thy categories are according to British Thyroid Association system.
