Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Statistics
  • Radiology

Nathaniel M. Alpert focuses on Neuroscience, Cerebral blood flow, Cognitive psychology, Mental image and Audiology. His Cerebral blood flow study incorporates themes from Blood flow, Orbitofrontal cortex, Psychiatry, Neuroimaging and Anxiety disorder. His Blood flow research includes themes of Positron emission tomography, Emission computed tomography, Hemodynamics and Heart rate.

His Cognitive psychology research includes elements of Semantic memory and Broca's region. His Mental image study integrates concerns from other disciplines, such as Perception, Mental representation and Visual cortex. His Frontal lobe research focuses on Prefrontal cortex and how it relates to Context and Verbal learning.

His most cited work include:

  • A symptom provocation study of posttraumatic stress disorder using positron emission tomography and script-driven imagery (824 citations)
  • Regional Cerebral Blood Flow Measured During Symptom Provocation in Obsessive-Compulsive Disorder Using Oxygen 15—Labeled Carbon Dioxide and Positron Emission Tomography (762 citations)
  • Regional Cerebral Blood Flow in the Amygdala and Medial Prefrontal Cortex During Traumatic Imagery in Male and Female Vietnam Veterans With PTSD (642 citations)

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

Nathaniel M. Alpert mostly deals with Nuclear medicine, Positron emission tomography, Neuroscience, Internal medicine and Blood flow. His Positron emission tomography research focuses on Pharmacokinetics and how it connects with Pathology. His research investigates the connection between Neuroscience and topics such as Cognitive psychology that intersect with issues in Frontal lobe.

His work deals with themes such as Endocrinology and Cardiology, which intersect with Internal medicine. Nathaniel M. Alpert interconnects Hemodynamics and Cerebral blood flow in the investigation of issues within Blood flow. The study incorporates disciplines such as Anxiety disorder, Psychiatry and Audiology in addition to Cerebral blood flow.

He most often published in these fields:

  • Nuclear medicine (23.36%)
  • Positron emission tomography (20.87%)
  • Neuroscience (17.76%)

What were the highlights of his more recent work (between 2010-2021)?

  • Nuclear medicine (23.36%)
  • Positron emission tomography (20.87%)
  • Membrane potential (3.43%)

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

The scientist’s investigation covers issues in Nuclear medicine, Positron emission tomography, Membrane potential, Blood flow and Imaging phantom. Many of his research projects under Nuclear medicine are closely connected to Materials science with Materials science, tying the diverse disciplines of science together. His work often combines Positron emission tomography and Biomarker studies.

His Blood flow research incorporates elements of Dynamic contrast-enhanced MRI and Single scan. The various areas that Nathaniel M. Alpert examines in his Imaging phantom study include Sensitivity, Curve fitting, Iterative reconstruction and Conjugate gradient method. The Neuroimaging study combines topics in areas such as Cognitive psychology, Orbitofrontal cortex, Functional connectivity, Ventral striatum and Neurocognitive.

Between 2010 and 2021, his most popular works were:

  • MRI-Based Nonrigid Motion Correction in Simultaneous PET/MRI (145 citations)
  • Nonrigid PET motion compensation in the lower abdomen using simultaneous tagged-MRI and PET imaging. (93 citations)
  • Neurovascular coupling to D2/D3 dopamine receptor occupancy using simultaneous PET/functional MRI (82 citations)

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

  • Internal medicine
  • Radiology
  • Statistics

His main research concerns Nuclear medicine, Positron emission tomography, Biomedical engineering, Imaging phantom and Neuroimaging. His study in the field of PET-CT is also linked to topics like Materials science. Nathaniel M. Alpert works mostly in the field of Positron emission tomography, limiting it down to topics relating to Blood flow and, in certain cases, Single scan and Cardiac PET.

His Imaging phantom research includes themes of Proton therapy, Iterative reconstruction and Perfusion. His Neuroimaging study integrates concerns from other disciplines, such as Cognitive psychology, Orbitofrontal cortex, Functional connectivity, Dopamine and Brain chemistry. His Basal ganglia study is related to the wider topic of Neuroscience.
