FDG-PET/CT: Lesion Glycolysis In Patients With Lymphoma

Whether baseline metabolic tumor volume (TMTV) and total lesion glycolysis (TLG) measured by FDG-PET/CT affected prognosis of patients with lymphoma was controversial. We searched PubMed, EMBASE and Cochrane to identify studies assessing the effect of baseline TMTV and TLG on the survival of lymphoma patients. Pooled hazard ratios (HR) for overall survival (OS) and progression-free survival (PFS) were calculated, along with 95% confidence intervals (CI). 

Mini EXPLORER II: Whole Body PET/CT Project

As part of the EXPLORER total-body positron emission tomography (PET) project, we have designed and built a high-resolution, high-sensitivity PET/CT scanner which is expected to have excellent performance for companion animal whole body and human brain imaging. The PET component has a ring diameter of 52 cm and an axial field of view of 48.3 cm. 

Correction For Quantitative PET Imaging Using Dynamic MRI

Cardiac PET / MRI acquisition presents novel clinical applications thanks to the combination of viability and metabolic imaging (PET) and functional and structural imaging (MRI). However, the resolution of PET, as well as cardiac and respiratory motion in non-gated cardiac imaging acquisition protocols, leads to a reduction in image quality and severe quantitative bias. Respiratory or cardiac motion is usually treated with gated reconstruction which results in higher noise.

18F-FDG Cardiac PET Inflammation With Breast Cancer Radiotherapy

Radiotherapy for the treatment of left-sided breast cancer increases the long term risk of cardiovascular disease. The purpose of this study was to non-invasively image the progression of radiation-induced cardiac inflammation in a large animal model using a hybrid positron emission tomography and magnetic resonance imaging system.
