494 Objectives The purpose of our study was to explore the influence of dental filing artifacts
in head and neck PET/MRI imaging. Methods In ongoing study, several patients were …

1409 Objectives Dental restorations (fillings) cause extensive image distortion and bias in
PET/CT data following CT-based attenuation correction (CT-AC). In PET/MRI AC is …

2335 Objectives The aim of our study was to investigate the differences between PET
images obtained on PET/MRI system, and corrected for attenuation using external CT and …

2077 Objectives The aims of the study were to evaluate the effect of dental metal prostheses
in phantom and patients on apparent tracer activity measured with PET/CT when using CT …

In patients with oral head and neck cancer, the presence of metallic dental implants
produces streak artifacts in the CT images. These artifacts negate the utility of CT for the …

PET/CT imaging is particularly performed for diagnosis and staging of head and neck
malignancies. The xray attenuation coefficient based on computed tomography (CT) images …

Germanium-68 based attenuation correction (PET Ge68) is performed in positron emission
tomography (PET) imaging for quantitative measurements. With the recent introduction of …

The purpose of this study was to investigate the clinical usefulness of PET/CT or CT-
attenuated PET in the evaluation of patients with oral cavity cancer (OCC) in whom dental …

Recent studies have shown increased artifacts in CT attenuation-corrected (CTAC) PET
images acquired with oral contrast agents because of misclassification of contrast as bone …

1299 Objectives: To demonstrate the feasibility of zero-echo-time (ZTE) MR imaging for jaw
bones and to evaluate the quantitative performance of 2-[18 F]-fluoro-2-deoxy-D-glucose (18 …
