AI Article Synopsis
- Vascular graft infection (VGI) is a rare but serious complication after vascular surgery that can lead to high morbidity and mortality, making diagnosis challenging due to varied symptoms.
- Computed tomography (CT) is the preferred method for diagnosing advanced VGI, but it often returns false-negative results, especially in milder cases.
- F-Fluorodeoxyglucose positron emission tomography with contrast-enhanced CT (F-FDG PET-CT) can effectively diagnose VGI and accurately locate the site of infection, as illustrated by three case studies demonstrating its utility.
Article Abstract
Vascular graft infection (VGI) is a rare and severe complication after vascular surgery associated with significant morbidity and mortality, but the diagnosis is not always straightforward due to its variable and nonspecific clinical signs. Computed tomography (CT) scan is considered to be the diagnostic tool of choice for advanced VGI, but there is a high incidence of false-negative results, especially in low-grade infections. F-Fluorodeoxyglucose positron emission tomography with contrast-enhanced CT (F-FDG PET-CT) imaging can serve as an effective alternative tool for assessment of suspected VGI and also provide accurate anatomic localization of the infective focus. Here, we describe three cases of VGI with various clinical presentations where the site of infection was diagnosed, confirmed, and documented with the help of F-FDG PET-CT imaging.

Background: Positron emission tomography (PET) imaging greatly impacted Alzheimer's disease (AD) research and diagnosis. which makes predicting PET brain imaging alterations using blood data is of high interest. Additionally, integrating PET and omics data can provide new insights into AD pathophysiology.

Background: Disturbed sleep has been associated with Alzheimer's disease (AD) dementia. Nevertheless, limited information is yet available for the relationship between sleep experiences and longitudinal changes of brain pathologies related to AD. This study aimed to investigate the association between late-life sleep experiences and the prospective changes of in vivo AD pathologies and cerebrovascular injury over 2 years in cognitively normal (CN) old adults.

The study investigates the prognostic value of [F]fluorodeoxyglucose (FDG) PET/CT in patients with idiopathic pulmonary fibrosis (IPF). A total of 346 IPF patients who underwent FDG PET/CT between 2007 and 2020 were analyzed. Pulmonary FDG uptake [target to background ratio (TBR)] was binarized by optimal cut-off value based on survival analysis.

Objectives: to investigate the capability of F-fluorodeoxyglucose positron emission tomography/computed tomography ([F]-FDG PET/CT) derived volumetric parameters to predict human epidermal growth factor receptor 2 (HER2) status in breast cancer patients.
Methods: retrospective study enrolled 47 female patients with breast cancer. All patients had pretreatment [F]-FDG PET/CT.
Imaging of unicentric hyaline-vascular variant of Castleman disease: Emphasis on perilesional fat stranding and fatty proliferation.

Department of Radiology, Institute of Medicine, University of Tsukuba, Ibaraki, Japan.
The hyaline-vascular variant of Castleman disease (HVCD) is relatively uncommon and demonstrates no specific clinical or laboratory findings; therefore, its preoperative diagnosis warrants a radiological evaluation. This study aimed to review imaging findings of HVCD, focusing on perilesional fat stranding and fatty proliferation. Patients with a pathologically confirmed HVCD diagnosis who had undergone CT were recruited from five hospitals from January 2000 to March 2023.
