PET/MR: a paradigm shift [PDF]

Cancer Imaging, 2013
More than a decade ago, multimodality imaging was introduced into clinical routine with the development of the positron emission tomography (PET)/computed tomography (CT) technique. Since then, PET/CT has been widely accepted in clinical imaging and has emerged as one of the main cancer imaging modalities.

Design and system evaluation of a dual-panel portable PET (DP-PET)

EJNMMI Physics, 2021
Background Integrated whole-body PET/MR technology continues to mature and is now extensively used in clinical settings. However, due to the special design architecture, integrated whole-body PET/MR comes with a few inherent limitations.

Human Papillomavirus Status and the Risk of Cerebrovascular Events Following Radiation Therapy for Head and Neck Cancer

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundRadiation therapy (RT) is a standard treatment for head and neck cancer; however, it is associated with inflammation, accelerated atherosclerosis, and cerebrovascular events (CVEs; stroke or transient ischemic attack). Human papillomavirus (HPV)

Incidence, Predictors, and Outcomes of Implantable Cardioverter‐Defibrillator Discharge Among People Living With HIV

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
Background People living with HIV (PHIV) are at an increased risk for sudden cardiac death, and implantable cardioverter‐defibrillators (ICDs) prevent SCD. There are no data on the incidence, predictors, and effects of ICD therapies among PHIV.
