DOTA-NOC PET/CT raises the bar in neuroendocrine imaging

By Jonathan S. Batchelor

Receptors for the naturally occurring neuropeptide somatostatin have been shown to have a high concentration on neuroendocrine tumors. Indium-111-labeled octreotide has long been the preferred agent for imaging somatostatin receptors on neuroendocrine tumors in vivo. But a recent study by German researchers indicates that there may be a new radiotracer of choice for neuroendocrine carcinoma imaging, Ga-68 DOTA-NOC.

PET plays universal role in pre- and post-treatment for head and neck cancer

By Shalmali Pal

Predicting the success of head and neck cancer treatment, staging it, and addressing its side effects are the focus of three recent papers. German investigators devised a tumor control model using repeat PET scanning during radiotherapy, while a group from Stanford University offered practical PET/CT guidelines for this disease. Finally, the North Central Cancer Treatment Group tested zinc sulfate in preventing dysgeusia in patients undergoing radiation to the oral pharynx.

By Eric Barnes

You'll need more than CT and MRI scanners to run a decent stroke center, according to a stroke practice expert from Germany. You'll need staff with expertise in diagnosing and treating the full range of ischemic and hemorrhagic stroke presentations, and enough skilled interventionalists to care for patients who show up at midnight on a holiday.
