Comparative Study
18F-FDG-PET/MRI in preoperative staging of oesophageal and gastroesophageal junctional cancer.
To evaluate integrated 2-[18F]-fluoro-2-deoxy-d-glucose (18F-FDG) positron-emission tomography (PET)/magnetic resonance imaging (MRI), in comparison with the standard technique, integrated 18F-FDG-PET/computed tomography (CT), in preoperative staging of oesophageal or gastroesophageal junctional cancer. ⋯ Preoperative staging with 18F-FDG-PET/MRI is safe and promising with the potential to enhance tissue resolution in the area of interest. 18F-FDG-PET/MRI and 18F-FDG-PET/CT correlated well for most of the measured values and discrepancies were seen mainly in the assessment of the T-stage. These results facilitate further studies investigating the role of 18F-FDG-PET/MRI in, e.g., predicting or determining the response to neoadjuvant therapy.

To evaluate the feasibility of T1-weighted (T1W) three-dimensional (3D) fat saturated Cartesian volumetric interpolated breath-hold examination (VIBE) magnetic resonance imaging (MRI) sequence for the diagnosis of aortitis in patients with suspected large vessel vasculitis (LVV) applying fully integrated 2-[18F]-fluoro-2-deoxy-d-glucose (18F-FDG) positron-emission tomography (PET)/MRI. ⋯ T1W 3D fat saturated VIBE MRI allows diagnosis of aortitis and may aid in the management of patients with suspected LVV.
