Large vessel vasculitis (LVV) is defined as a disease mainly affecting the large arteries, with two major variants, Takayasu arteritis (TA) and giant cell arteritis (GCA). GCA often coexists with polymyalgia rheumatica (PMR) in the same patient, since both belong to the same disease spectrum. FDG-PET/CT is a functional imaging technique which is an established tool in oncology, and has also demonstrated a role in the field of inflammatory diseases. Functional FDG-PET combined with anatomical CT ...

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-fluor...

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.

Abstract Two patients with aortoiliac occlusive disease underwent dynamic and late-static positron emission tomography/computed tomography (PET/CT) acquisitions with 257 and 244 MBq F-18 FDG (CT scan parameters 50 mAs, 120 kV, pitch 1.25). Three-dimensional reconstructions revealed an occluded aortic stent and a high-grade aortic stenosis and demonstrated the relations of vascular pathologies to adjacent structures. Early-dynamic PET can be performed without additional radioactive tracer and may...

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.

Background Necroscopic and surgical studies have suggested that giant cell arteritis (GCA) may target the aorta and its main branches. Imaging techniques are able to detect large vessel vasculitis (LVV) non-invasively in patients, but the prevalence of LVV in GCA has not been clearly established. Objective To assess prospectively the prevalence, characteristics and topography of LVV in patients with newly diagnosed GCA and to determine the associated clinical and laboratory features. Methods CT ...

Objective: To quantify 18-fluorodeoxyglucose (FDG) accumulation in large vessels in patients with polymyalgia rheumatica by positron emission tomography (PET), and to compare these data with serological markers of inflammation. Methods: 13 untreated patients with active polymyalgia rheumatica underwent FDG positron emission tomography; eight were analysed in a second PET when in clinical remission. Six patients with other highly inflammatory conditions served as controls. For quantitative analys...

Abstract Pseudoaneurysm formation is a known complication of peripheral arterial access procedures. Although standard contrast angiography has been considered the diagnostic study of choice to identify pseudoaneurysms, isotope angiography has been described as an alternative method. In this study, we examined the role of99mTc-tagged red blood cell scans in the diagnosis of traumatic pseudoaneurysm. Forty patients underwent scans; 25 scans were reported as abnormal and 15 as normal. There were no...
