Neuroimaging Flashcards
What is the primary advantage of MRI over CT for brain imaging?
MRI provides better soft tissue contrast.
Fill in the blank: The ________ is a structure in the brain responsible for coordination and balance.
cerebellum
Which imaging technique is preferred for detecting brain tumors in pediatric patients?
MRI
What is the purpose of contrast agents in MRI?
To enhance the visibility of certain structures.
Identify the structure: It is the largest part of the human brain and is involved in higher cognitive functions.
Cerebrum
True or False: The brainstem controls basic life functions such as breathing and heart rate.
True
What does T1-weighted MRI emphasize?
Fat and anatomical detail.
Which pediatric brain structure is most commonly associated with hydrocephalus?
Ventricles
Multiple Choice: Which of the following is NOT a part of the limbic system? A) Hippocampus B) Amygdala C) Cerebellum D) Thalamus
C) Cerebellum
What imaging technique is often used to assess acute head trauma in children?
CT scan
Fill in the blank: The ________ is the thin layer of tissue covering the brain.
meninges
Identify the structure: This part of the brain is responsible for processing visual information.
Occipital lobe
What is the significance of the corpus callosum?
It connects the left and right cerebral hemispheres.
Multiple Choice: Which imaging modality is safer for children due to no radiation exposure? A) CT B) MRI C) X-ray D) PET
B) MRI
What does DTI stand for in the context of MRI?
Diffusion Tensor Imaging
Fill in the blank: The ________ lobe is primarily responsible for auditory processing.
temporal
Identify the structure: This part of the brain regulates hormones and is involved in homeostasis.
Hypothalamus
True or False: Pediatric brains are more susceptible to radiation damage than adult brains.
True
What is the role of the thalamus in the brain?
It acts as a relay station for sensory information.
Multiple Choice: Which structure is primarily involved in memory formation? A) Cerebellum B) Hippocampus C) Brainstem D) Basal ganglia
B) Hippocampus
What is one common indication for performing a brain MRI in children?
Suspected brain tumor or lesion.
Identify the structure: This part of the brain is essential for voluntary motor control.
Basal ganglia
What is the abbreviation for Focal aware seizure?
FAS
What is the abbreviation for Focal impaired awareness seizure?
FIAS
