Article Synopsis
- The study evaluated the repeatability of 18F-FDG PET/MR imaging for measuring glucose uptake in the liver, focusing on standardized uptake values normalized for body weight and lean body mass.
- 35 patients participated in the tests, and various locations in the liver were analyzed for PET/MR accuracy.
- Results showed that the most consistent measurements were taken below the portal vein, indicating it as the best spot for assessing liver glucose uptake.
Background: Pulmonary infiltrates (PIs) detected in patients with non-Hodgkin lymphoma (NHL) may present a diagnostic challenge due to their wide differential diagnosis, including infection, pulmonary lymphoma and immunochemotherapy-associated pulmonary toxicity.
Objectives: To characterize therapy-associated PIs by positron emission tomography/computed tomography (PET/CT) imaging.
Methods: We conducted a historical analysis of fluorodeoxyglucose-PET/CT (18F-FDG-PET/CT) PIs in NHL patients treated with combined immunochemotherapy including rituximab.
Purpose: To prospectively determine whether fluorine 18 fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) early dynamic blood flow estimates could be used to discriminate hepatocellular carcinoma (HCC) from background liver and to characterize HCC in patients with and those without angioinvasion; and to evaluate the association between blood flow measures at FDG PET/CT with metabolism in HCCs.
Materials And Methods: Institutional review board approval and written informed consent were obtained for this prospective study. Twenty-one consecutive patients (mean age, 65 years) with 30 established HCCs (mean size, 5.
Article Synopsis
- The study aimed to analyze the significance of accessory spleen-like mass (ASLM) in oncology patients using PET/CT imaging.
- The findings revealed that ASLM occurred in 14.8% of patients, with a higher incidence in lymphoma patients compared to those with solid tumors, and some ASLMs showed pathological uptake indicative of malignancy.
- The conclusion suggests that while ASLMs can represent cancer in lymphoma patients, those with other types of cancer can be confidently diagnosed as having accessory spleen without further concern.
Unlabelled: We combined (18)F-FDG PET and CT enterography in a single examination and compared the level of (18)F-FDG uptake measured by maximal standardized uptake value (SUVmax) with the CT enterography patterns of disease activity found in patients with Crohn disease (CD).
Methods: Twenty-eight patients (mean age, 37.5 y; 11 male and 17 female) suspected of having active CD underwent PET/CT enterography.
The metabolic spectrum of venous thrombotic disorders found on PET/CT.

Objective: Thrombotic disorders detected on PET/CT are usually incidental findings and may change the treatment strategy and patient's disease prognosis. The purpose of this article is to present the spectrum of venous thrombotic disorders found on PET/CT.
Conclusion: The division of thrombotic disorders into metabolically nonactive and active thrombus may be helpful for differential diagnosis of underlying diseases causing thrombus formation.
Objective: The purpose of this article is to illustrate the spectrum of common benign intraarticular and extraarticular disorders associated with focal (18)F-FDG uptake in the shoulder and pelvic areas in oncology patients referred for PET/CT.
Conclusion: A wide spectrum of benign musculoskeletal disorders associated with focal FDG uptake may be detected in cancer patients. This incidental uptake usually does not seem to be a clinically significant finding, but it can affect quality of life.
