A comprehensive 3D model of human neuronal pathophysiology leading to Alzheimer’s disease is now complete. The final model provides confirmation of how amyloid plaque build-up and tau neurofibrillary tangles are not just related to onset of disease, but that amyloid hastens tau pathology, according to a letter published online Oct. 12 in Nature.

Navidea Biopharmaceutical’s supplemental new drug application for sentinel lymph-node mapping agent Lymphoseek (technetium Tc 99m tilmanocept) has now been approved for detection of lymph node involvement in all solid tumors, the company announced today.

While CT and MR are still the mainstays of detecting ischemic stroke, several SPECT and PET imaging techniques have been developed and are on the way to add comprehensive clinical information in the case of cerebrovascular disease. With this in mind, hybrid imaging such as PET/MR could provide a best-possible map of variables involved in stroke, according to a review published Oct. 9 in the Journal of Nuclear Medicine.

A workshop for intraoperative imaging including discussion about the most novel techniques in the discipline was recently conducted during the Congress of the World Molecular Imaging Society (WMIS) in Seoul, Korea. The workshop featured presentations on intraoperative and real-time use of laser light and light-emitting agents, CCD cameras and ultraminiaturized microscopes, the WMIS announced yesterday.

A new and tiny camera steals from the sight of the powerful, all-seeing mantis shrimp in order to detect cancers that we currently cannot. The new and rather simple system relies on polarized light, which these shrimps can see in spades, to create a whole new dimension of cancer imaging, according to this report from Smithsonian.

A searchable database of 100,000 SPECT neuroimaging studies that incorporates scans from 111 different countries and subjects ranging from nine months to 101 years old was introduced today by Amen Clinics, a network of psychiatric clinics based in Costa Mesa, Calif. The intention of the database is to promote open collaboration and interdisciplinary study of psychiatric and related disorders.

Saturday marked the final day of the 2014 Nuclear Medicine and Molecular Imaging Week and, to celebrate, the World Molecular Imaging Society (WMIS) announced highlights of the recent 7th World Molecular Imaging Congress held in Seoul, Korea.

The National Cancer Institute has mounted a search for people who are dramatic outliers in their response to cancer therapies in an effort to improve treatments for common malignancies.
