Dear AuntMinnie Member,
PET/MRI is one of the most exciting new technologies in medical imaging, and this week in our Molecular Imaging Digital Community we're highlighting new research out of Germany that investigates the hybrid modality for head and neck cancer.
Like PET/CT, the benefit of PET/MRI is that it combines PET's expertise in functional imaging with the anatomical resolution of another modality, in this case MRI. PET/MRI could be superior to PET/CT due to MRI's better ability to visualize soft-tissue structures.
The researchers tested PET/MRI in a small group of patients with head and neck tumors, and compared their results to PET/CT. Learn more about this study by clicking here, or visit molecular.auntminnie.com.
Thyroid shielding cuts CT dose
Another hot topic has been radiation dose, and a new article in our CT Digital Community this week offers guidance on how to reduce it for thyroid studies.
South Korean researchers used a commercially available bismuth-based shield placed on patients' necks during thyroid scans. They then measured radiation dose that patients received during the exams, and for good measure assessed whether the shield had an impact on the amount of noise in CT images.
How well did it work? Find out by clicking here, or visit the CT Digital Community at ct.auntminnie.com.
