A PET detector combining time-of-flight (TOF) and depth-of-interaction (DOI) capabilities has been developed by a US-Italian collaboration. A high timing resolution of around 200 ps, along with accurate DOI estimates and good energy resolution, was demonstrated by the detector. The technology promises to significantly boost PET image quality, with whole-body imaging applications, such as scans for cancer metastases, set to benefit most (J. Med. Imag. 3 043501). {read more here}

With its ability to achieve a high level of specificity, the combination of carbon-11-labeled Pittsburgh Compound B (PiB) with PET imaging is showing early promise in distinguishing meningiomas from other intracranial tumors, according to a study presented recently at RSNA 2016. {read more here}

A German multicenter study, initiated by the German Society of Nuclear Medicine, demonstrates that lutetium-177 (Lu-177)-labeled PSMA-617 is a promising new therapeutic agent for radioligand therapy (RLT) of patients with metastatic castration-resistant prostate cancer (mCRPC). The study is published in the January 2017 issue of the Journal of Nuclear Medicine and is the featured article. {read more here}

The study retrospectively compared vascular and subcutaneous adipose tissue inflammation, as assessed by FDG-PET/CT in 12 patients with moderate-to-severe psoriasis and 24 matched controls without psoriasis. At the conclusion of the study, psoriasis was demonstrated to be associated with significantly increased aortic and subcutaneous adipose inflammation. The results of this study further corroborate that there may be a link between psoriasis skin inflammation, vascular inflammation, cardiovascular disease, and obesity. {read more here}
