When Atlanta-based The Radiology Group was founded in 2006, it looked like a traditional private radiology practice, albeit a family affair. Anand Lalaji, MD, a musculoskeletal radiologist, his wife Tejal Lalaji, MD (a neuroradiologist and breast imager) and his father-in-law Mahendra Patel, MD, (a body imager) grew the practice over the subsequent three years into a thriving enterprise with multiple hospital and imaging center clients in Northeast Georgia. 

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.

Serving the community of upstate New York’s Capital Region, Adirondack Radiology Associates (ARA) recently expanded patients’ access to state-of-the-art, high-field open bore MR imaging technology, replacing two systems, an older low-field open system and a closed 1.5T system, with the Hitachi Oasis high-field open MR at their Saratoga Imaging Center. Since the installation, ARA has experienced an increase in procedure volumes and patient satisfaction as well a reduction in costs. 

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.
