To accurately assess tumour response to treatment using imaging, measurement of the repeatability of an imaging biomarker – defined as the variation of repeated measurements in an experiment performed under the same conditions – is essential. With this aim, three US institutions have quantitatively evaluated ¹⁸F-NaF PET-derived standardized uptake value (SUV) metrics to determine their repeatability in individual bone lesions (J. Nucl. Med. doi: 10.2967/jnumed.116.177295). {read more here}

Mammograms have been responsible for alerting hundreds of thousands of women of the presence of breast cancer, but a new test is even more effective for women with dense breasts. The process, called molecular breast imaging, is performed in conjunction with a traditional mammogram and helps identify cancer that test may have missed.  {read more here}

A new study conducted by a team of investigators affiliated with the University of Toronto provides evidence to the contrary, and findings indicate that microglial activation is not present in untreated patients diagnosed with first-episode psychosis. These findings were published in The American Journal of Psychiatry. {read more here}
