Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Brain Imaging

Brain Imaging

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 Stimulation (TMS).

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Brain Waves

Brain Waves

Brain waves are electrical signals generated by the neurons in the brain, which are regularly monitored to measure mental activities. Brain waves and their frequency ranges can be measured using an electroencephalogram or EEG. There are four main types of brain waves, each with distinct characteristics:

Area of Science:

Neuroscience
Biomedical Imaging
Animal Models

Background:

High-field MRI enables BOLD fMRI in small animals, enhancing spatial resolution.
Susceptibility artifacts in gradient echo images pose challenges, especially in birds with air cavities.
Spin echo BOLD fMRI offers a solution to these imaging challenges.

Purpose of the Study:

To describe a protocol for spin echo BOLD fMRI in zebra finches.
To address challenges in high-field MRI for avian brain imaging.
To facilitate auditory stimulus-based fMRI studies in songbirds.

Main Methods:

Implementation of spin echo BOLD fMRI technique.
Application on small songbirds (zebra finches, 15-25 g).
Inclusion of auditory stimuli in the fMRI protocol.

Main Results:

Successfully adapted spin echo BOLD fMRI for zebra finch brain imaging.
Overcame susceptibility artifacts common in high-field MRI of avian skulls.
Established a viable method for studying brain function in response to auditory stimuli.

Conclusions:

Spin echo BOLD fMRI is effective for high-resolution brain imaging in zebra finches.
This method advances the study of auditory processing and birdsong neuroscience.
The protocol provides a foundation for future research in avian neurobiology.
