Brain Imaging01:14

Brain Imaging

734
Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Long-term Depression01:05

Long-term Depression

33.3K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Regional Terms

15.5K
Regional terms describe anatomy by dividing the body parts into different regions that contain structures involved in contributing similar functions. Using these terms helps increase the accurate description and identification of the particular region of interest or region affected by the disease.
Primarily, the human body has two major regions, the axial and appendicular regions. The axial region comprises regions from the head to the abdomen and makes up the central body axis. In contrast,...

Long-Term Memory01:18

Long-Term Memory

674
Long-term memory is a relatively permanent type of memory, capable of storing vast amounts of information over extended periods. Its storage capacity is generally considered unlimited.
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...

Area of Science:

  • Neonatal neurology
  • Medical imaging
  • Pediatric radiology

Background:

  • Brain imaging is crucial for diagnosing and managing sick term neonates.
  • Ultrasound and CT offer limited information compared to MRI.
  • Neonatal encephalopathy, often due to hypoxic-ischemic injury, requires precise brain assessment.

Purpose of the Study:

  • To outline the principles, roles, and limitations of key brain imaging modalities in term neonates.
  • To provide recommendations for the appropriate use of brain imaging in this population.
  • To focus on imaging for term infants with neonatal encephalopathy, including hypoxic-ischemic encephalopathy.

Main Methods:

  • Review of principles, roles, and limitations of ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI).
  • Focus on application in term neonates, particularly those with neonatal encephalopathy.
  • Evidence-based recommendations for imaging modality selection.

Main Results:

  • Magnetic resonance imaging (MRI) is identified as the most sensitive technique for detecting and quantifying brain abnormalities in neonates.
  • MRI does not involve ionizing radiation, making it safer for infants.
  • Ultrasound and CT have specific, albeit more limited, roles.

Conclusions:

  • MRI is the brain imaging modality of choice for term neonates due to its high sensitivity and safety profile.
  • Appropriate use of imaging modalities, guided by clinical context, is essential for optimal neonatal care.
  • This statement provides a framework for selecting the best imaging approach for neonatal brain conditions.
