Cross-sectional and vertical images of the brain for visualization and evaluation of tumors, edema, and herniated disks are produced by
A) lumbar puncture
B) positron emission tomography
C) magnetic resonance imaging
D) electroencephalogram

Question

Quizplus · Accepted Answer

Magnetic resonance imaging (MRI) is a non-invasive technique which produces detailed cross-sectional and vertical images of the brain. It uses a strong magnetic field and radio waves to generate images of the body's internal structures. This technique is useful in visualization and evaluation of tumors, edema, and herniated disks. Lumbar puncture (A) is a procedure used to collect cerebrospinal fluid (CSF) for diagnostic purposes, whereas positron emission tomography (B) is a medical imaging technique that uses radioactive substances to visualize metabolic processes in the body. An electroencephalogram (D) is a test that measures electrical activity in the brain and is used to diagnose conditions such as epilepsy or seizure disorders.
