Long Coronavirus Disease and the Brain
The coronavirus disease 2019 (COVID-19) pandemic has led to a variety of health challenges, with “long COVID” emerging as a widespread and debilitating post-acute syndrome among a considerable number of…
Brain Tumor Assessment
While MR imaging is the main imaging modality to assess brain tumors, PET imaging has a specific role. Among the many tracers that have been proposed and are still being…
A Brief History and the Use of PET in the Diagnosis and Management of Schizophrenia
This article explores the role of PET in the diagnosis and treatment of schizophrenia. PET imaging can reveal neurobiologic aspects such as cerebral blood flow, glucose metabolism, receptor function, and…
Movement Disorders and Its Variants
Since the 2000s, Nuclear Medicine has primarily used SPECT with DaTSCAN and PET with [18F]-FDG to explore movement disorders. Recent advances in PET radiotracers, such as LBT 999 for dopamine…
Metabolic Brain PET Connectivity
This review examines the role of metabolic connectivity based on fluorodeoxyglucose-PET in understanding brain network organization across neurologic disorders, with a focus on neurodegenerative diseases. The article explores key methodologies…
Novel PET-CT-MR Imaging Based Quantitative Technique for Accurate Assessment of Radiation Induced Injuries
Radiation-induced injuries (RIIs) are significant complications of radiation therapy used in cancer treatments and affect organs in a systemic fashion such as the heart, lungs, liver, and bone marrow. Such…
Evolving Role of PET Imaging in Assessing Vascular and Central Nervous System Complications of Radiation Therapy in Head and Neck Cancer
Radiation therapy for head and neck cancer is a cornerstone of treatment but can come with significant and lasting complications. Reduced vascularity and fibrosis heighten the risks of stroke, infection,…
Radiation-Induced Coronary Artery Disease in Lung and Breast Cancer Patients
Radiation-induced coronary artery disease (RI-CAD) is a significant cardiovascular complication for cancer survivors treated with thoracic radiation therapy (RT). Despite advances in RT techniques, exposure to the heart during treatment…
Updates in the Role of Positron Emission Tomography/Computed Tomography in Radiation Oncology in Gastrointestinal Malignancies
Positron Emission Tomography/Computed Tomography (PET/CT) plays a critical role in managing gastrointestinal (GI) cancers within radiation oncology. It enhances tumor detection, staging, and lymph node involvement assessment, leading to better-targeted…
Integrating Prostate Specific Membrane Antigen-PET into Clinical Practice for Prostate Cancer
Prostate surface membrane antigen (PSMA)-PET imaging has significantly shaped the clinical management of prostate cancer, from localized to metastatic disease. It outperforms conventional imaging in both primary staging and detecting…
