PURPOSE We tested the performance and clinical applicability of combined protocols for brain imaging studies acquired on a new whole-body hybrid PET/MR scanner. PATIENTS AND METHODS Fifteen patients [6 male and 9 female patients; mean (SD) age, 51 (30) y; range, 6-89 y] were scanned on a Philips Ingenuity TF PET/MR. Standard imaging protocols of both(More)
PET and MRI are established clinical tools which provide complementary information, but clinical workflow limits widespread clinical application of both modalities in combination. The two modalities are usually situated in different hospital departments and operated and reported independently, and patients are referred for both scans, often consecutively.(More)
Several studies have reported on the use of high-resolution Y PET/CT scans in the evaluation of the biodistribution of Ylabelled glass or resin based microspheres after radioembolisation of malignant liver lesions [1–4]. PET/MR is an emerging technology providing particularly high soft tissue contrast and no inherent radiation exposure. A 67-year-old man(More)
Magnetic resonance imaging (MRI) is the examination method of choice for the diagnosis of a variety of diseases. MRI allows us to obtain not only anatomical information but also identification of physiological and functional parameters such as networks in the brain and tumor cellularity, which plays an increasing role in oncologic imaging, as well as blood(More)
In patients with pharmacoresistant focal epilepsy, resection of the epileptic focus can lead to freedom from seizures or significant improvement in well-selected candidates. Localization of the epileptic focus with multimodal concordance is crucial for a good postoperative outcome. Beyond the detection of epileptogenic lesions on structural MRI and focal(More)
BACKGROUND In chest computed tomography (CT), iterative reconstruction (IR) algorithms maintain diagnostic image quality (IQ) while significantly reducing the dose. PURPOSE To evaluate the impact of IR on IQ of chest CT at effective doses below 0.3 mSv. MATERIAL AND METHODS Twenty chest CT scans performed at effective dose below 0.3 mSv (CT1) were(More)
UNLABELLED Fusion of information from PET and MR imaging can increase the diagnostic value of both modalities. This work sought to improve (18)F FDG PET image quality by using MR Dixon fat-constrained images to constrain PET image reconstruction to low-fat regions, with the working hypothesis that fatty tissue metabolism is low in glucose consumption.

Methods A pilot study of eleven patients (6 fixed hypoperfusion on cardiac SPECT and 5 healthy volunteers) performed an imaging study using a hybrid PET/MRI (Philips). Viability assessed by 18F-FDG was performed in diseased patients along with MRI anatomic, functional and viability assessment as determined by transmural extent of late gadolinium enhancement(More)
