I am a nuclear medicine specialist and always trying to implement innovative diagnostic and therapeutic methods in imaging. My main research interests involve infectious and inflammatory diseases, tumor-immunology, and development of new-targeted diagnostic tools for PET imaging. The latter focus is carried out in close collaboration with our radiochemists.
Within the lymphoma research Groningen team we have a close collaboration with the department of hematology. The research is focused on finding new methods for diagnosis and therapy evaluation in several types of lymphomas. We have a special interest in post-transplant lymphatic disorders (PTLD). Furthermore, we are developing and evaluating several fields of radionuclide therapy, so called theranostics.
Myocardial perfusion reserve compared with peripheral perfusion reserve: A [13N]ammonia PET study
Published in: Journal of Nuclear Cardiology
INTRODUCTION: [13N]ammonia PET allows quantification of myocardial perfusion. The similarity between peripheral flow and myocardial perfusion is unclear. We compared perfusion flow in the myocardium with the upper limb during rest and adenosine stress [13N]ammonia PET to establish whether peripheral perfusion reserve (PPR) correlates with MPR. METHODS: [13N]ammonia myocardial perfusion PET-scans of 58 patients were evaluated (27 men, 31 women, age 64 ± 13 years) and were divided in four subgroups: patients with coronary artery disease (CAD, n = 15), cardiac syndrome X (SX, n = 14), idiopathic...

Whole body amyloid deposition imaging by 123I-SAP scintigraphy
Amyloidosis is the name of a group of diseases characterized by extracellular deposition of amyloid fibrils. Deposition of amyloid can be localized or systemic. The 123I-SAP-scan can be used to image extent and distribution of amyloid deposition in patients with systemic AA, AL and ATTR amyloidosis. Images are assessed in a semi-quantitative way by comparing each organ directly or indirectly to the normal blood-pool distribution. Considerable variation is observed between the findings on 123I-SAP-scan and clinical manifestations of organ disease. Regardless, the 123I-SAP-scan still provides both an impression...
Radionuclide imaging of bone marrow disorders
Published in: European Journal of Nuclear Medicine and Molecular Imaging
Noninvasive imaging techniques have been used in the past for visualization the functional activity of the bone marrow compartment. Imaging with radiolabelled compounds may allow different bone marrow disorders to be distinguished. These imaging techniques, almost all of which use radionuclide-labelled tracers, such as (99m)Tc-nanocolloid, (99m)Tc-sulphur colloid, (111)In-chloride, and radiolabelled white blood cells, have been used in nuclear medicine for several decades. With these techniques three separate compartments can be recognized including the reticuloendothelial system, the erythroid compartment and the myeloid compartment. Recent developments in research and the...
Effect of radiotherapy and chemotherapy on bone marrow activity: a 18F-FLT-PET study
Published in: Nuclear Medicine Communications
Background Radiotherapy (RT) and chemotherapy are important treatment modalities for a variety of malignant tumor types. During therapy for malignant diseases, often the limitation for further therapy is determined by the capability of the bone marrow to withstand radiochemotherapeutic effects. Evaluation of hematologic toxicity is commonly performed with peripheral blood counts, and occasionally, sampling of marrow through a bone marrow biopsy. Neither method provides a comprehensive assessment, as bone marrow biopsy is invasive, and both are subject to sampling variability. Fluorine-18-3′-fluoro-3′-deoxy-L-thymidine-PET (18F-FLT-PET) is a noninvasive method and related...
