Abstract
PURPOSE: To propose a positron emission tomography (PET)/computed tomography (CT) protocol including early-dynamic and late-phase acquisitions to evaluate graft patency and aneurysm diameter, detect endoleaks, and rule out graft or vessel wall inflammation after endovascular aneurysm repair (EVAR) in one examination without intravenous contrast medium. TECHNIQUE: Early-dynamic PET/CT of the endovascular prosthesis is performed for 180 seconds immediately after intravenous injection of F-18-fluorodeoxyglucose. Data are reconstructed in variable time frames (time periods after tracer injection) to visualize the arterial anatomy and are displayed as PET angiography or fused with CT images. Images are evaluated in view of vascular abnormalities, graft configuration, and tracer accumulation in the aneurysm sac. Whole-body PET/CT is performed 90 to 120 minutes after tracer injection. CONCLUSION: This protocol for early-dynamic PET/CT and PET angiography has the potential to evaluate vascular diseases, including the diagnosis of complications after endovascular procedures.

Purpose: To analyze the literature comparing ultrasound [duplex (DUS) or contrast-enhanced (CEUS)] or magnetic resonance imaging (MRI) with computed tomography angiography (CTA) for endoleak detection and aneurysm diameter measurement after endovascular aneurysm repair (EVAR). Methods: A systematic review identified 31 studies that included 3853 EVAR patients who had paired scans (DUS or CEUS vs CTA or MRI vs CTA) within a 1-month interval for identification of endoleaks during EVAR surveillance...

Abstract Purpose The purpose was to show the feasibility of F-18 choline positron emission tomography (PET) angiography for the evaluation of abdominal and iliac arteries. Methods Thirty-five patients were examined and image quality was scored. Findings were correlated with contrast-enhanced computed tomography. Results Image quality was best in the aorta and common iliac arteries (100% and 93% of vessels). Negative predictive values of PET angiography were excellent (100%), and positive predict...

Objective Positron emission tomography (PET) angiography utilizes early dynamic PET acquisitions for depiction of the arterial vasculature. The aim of this study was to assess image quality and to evaluate feasibility of F-18 FDG PET angiography of the abdominal arteries.

OBJECTIVE. Early dynamic PET/CT is primarily used for oncologic perfusion studies. The purpose of this article is to show how the modality can be applied for angiography with data reconstructed in time-based frames for direct visualization of arterial vessels. CONCLUSION. Our initial data suggest that PET angiography can be used to establish patency and delineate relevant stenoses and occlusions. It therefore may be a useful complement to conventional angiography.

Dynamic CT angiography after endovascular aneurysm repair revealed that the peak enhancement of the endoleaks is significantly different than that of the aorta and that endoleaks may not be adequately evaluated with conventional biphasic CT angiography protocols.

Results The 30-day operative mortality was 1.8% in the endovascular-repair group and 4.3% in the open-repair group (adjusted odds ratio for endovascular repair as compared with open repair, 0.39; 95% confidence interval [CI], 0.18 to 0.87; P = 0.02). The endovascular-repair group had an early benefit with respect to aneurysm-related mortality, but the benefit was lost by the end of the study, at least partially because of fatal endo graft ruptures (adjusted hazard ratio, 0.92; 95% CI, 0.57 to 1....

PURPOSE: To study the potential of integrated positron emission tomography and computed tomography (PET/CT) to identify aneurysm wall inflammation. METHODS: The level of F18-fluorodeoxyglucose (FDG) uptake was studied in aneurysmal and normal-sized aortas of 34 male patients [17 with abdominal aortic aneurysm (AAA) and 17 age-matched controls] identified in a database of 278 consecutive patients evaluated for staging of primary lung cancer. The maximal standardized uptake value (SUV) was calcula...

PET molecular imaging of 15 O-labeled water is the gold standard for measuring blood flow in humans. However, this requires an on-site cyclotron to produce the short-lived 15 O tracer, which is cost-prohibitive for most clinical PET centers. The purpose of this study was to determine if the early uptake of 18 F-FDG could be used to measure regional blood flow in tumors in the absence of 15 O-water. Methods: PET scans were obtained in patients being evaluated for tumor perfusion and glucose metab...

: We present a case of a type Ia endoleak detected using F-FDG PET/CT 10 years after an abdominal aortoiliac endovascular aneurysm repair in an 83-year-old man. The F-FDG PET/CT scan was performed to evaluate a solitary pulmonary nodule but, in addition, demonstrated unexpected blood pool activity outside the stent graft and within the abdominal aortic aneurysm sac, indicating an endoleak; no FDG activity should be present within the aneurysm sac after stent graft placement. A subsequent CT angi...
