Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Pathology
  • Neuroscience

His primary scientific interests are in Internal medicine, Putamen, Caudate nucleus, Dopamine and Pathology. His study in Internal medicine focuses on Dopamine receptor D2 and Raclopride. His biological study spans a wide range of topics, including Dopaminergic, Parkinson's disease and Striatum.

His Dopamine study results in a more complete grasp of Endocrinology. His Endocrinology study integrates concerns from other disciplines, such as Frontal lobe and Apparent oxygen utilisation. His studies deal with areas such as Positron emission tomography, Multiple sclerosis, Blood flow and Blood volume as well as Pathology.

His most cited work include:

  • Long-term changes of striatal dopamine D2 receptors in patients with Parkinson's disease: A study with positron emission tomography and [11C]raclopride (179 citations)
  • Long-term changes of striatal dopamine D2 receptors in patients with Parkinson's disease: A study with positron emission tomography and [11C]raclopride (179 citations)
  • Long-term changes of striatal dopamine D2 receptors in patients with Parkinson's disease: A study with positron emission tomography and [11C]raclopride (179 citations)

What are the main themes of his work throughout his whole career to date?

K. L. Leenders focuses on Internal medicine, Positron emission tomography, Pathology, Endocrinology and Putamen. His Internal medicine and Central nervous system disease, Dopamine receptor D2, Raclopride, Parkinson's disease and Central nervous system investigations all form part of his Internal medicine research activities. His studies in Positron emission tomography integrate themes in fields like Ictal, Blood flow, Blood–brain barrier and Meningioma.

His Degenerative disease and Brain tumor study in the realm of Pathology interacts with subjects such as Distribution Volume. His study in Putamen is interdisciplinary in nature, drawing from both Levodopa, Caudate nucleus and Substantia nigra, Dopaminergic. His Caudate nucleus research includes themes of Basal ganglia and Striatum, Dopamine.

He most often published in these fields:

  • Internal medicine (51.19%)
  • Positron emission tomography (38.10%)
  • Pathology (27.38%)

What were the highlights of his more recent work (between 1998-2009)?

  • Central nervous system disease (22.62%)
  • Positron emission tomography (38.10%)
  • Nuclear medicine (20.24%)

In recent papers he was focusing on the following fields of study:

K. L. Leenders spends much of his time researching Central nervous system disease, Positron emission tomography, Nuclear medicine, Neuroscience and Putamen. His study with Central nervous system disease involves better knowledge in Internal medicine. The Internal medicine study combines topics in areas such as Gastroenterology and Endocrinology.

The study incorporates disciplines such as Pharmacokinetics, Washout, Blood plasma and Meningioma in addition to Positron emission tomography. His work in Putamen is not limited to one particular discipline; it also encompasses Levodopa. His work deals with themes such as Associative learning, Verbal fluency test, Trail Making Test and Raclopride, which intersect with Caudate nucleus.

Between 1998 and 2009, his most popular works were:

  • Metabolic Network Abnormalities in Early Huntington’s Disease: An [18F]FDG PET Study (146 citations)
  • Reproducibility of regional metabolic covariance patterns: comparison of four populations. (107 citations)
  • Imaging Brain Tumor Proliferative Activity with [124I]Iododeoxyuridine (93 citations)

In his most recent research, the most cited papers focused on:

  • Internal medicine
  • Neuroscience
  • Pathology

Nuclear medicine, Neuroscience, Positron emission tomography, Huntington's disease and Central nervous system disease are his primary areas of study. His Nuclear medicine research is multidisciplinary, relying on both Pharmacokinetics, Washout, Blood plasma and Meningioma. His research in Striatum, Medial frontal gyrus, Midbrain and Limbic lobe are components of Neuroscience.

His Positron emission tomography research incorporates elements of Internal medicine, Disease, Pathology and Metabolic network. His studies in Huntington's disease integrate themes in fields like Caudate nucleus, Basal ganglia, Verbal fluency test and Raclopride. His Central nervous system disease research is multidisciplinary, incorporating elements of Fluorodeoxyglucose, Brain network and Cohort.
