Medullary Thyroid Carcinoma: An Update on Imaging

Figure 1

Imaging of metastatic medullary thyroid carcinoma using different radiological techniques: (a) whole-body magnetic resonance imaging, diffusion-weighted sequence (DWI), (b) whole-body contrast-enhanced magnetic resonance imaging, T1 weighted images (3D rendering DCE); (c) positron emission tomography/magnetic resonance imaging (18F-FDG-PET/MR imaging fusion technique); (d) positron emission tomography/computed tomography with 18F-FDG (18F-FDG PET/CT). Please note the excellent visualization of the multiple liver metastases (yellow arrow), mediastinal metastases (red arrow), and a large left iliac bone metastasis (green arrows) on DWI and DCE, comparable with 18F-FDG PET/CT, although they interrogate completely different biophysical tissue properties. Note that the images are not quite coregistered (arms up during PET acquisition and with arms down during MR imaging).
