WHAT IS MRI?
Magnetic Resonance Imaging (MRI) is a
non-invasive medical imaging technique. IMPORTANC
E OF MRI Used to visualize internal structures of
the body. Diagnosis, monitoring, and research
purposes.
3
MRI BASICS
Magnetization and relaxation of hydrogen
nuclei. Generation of radiofrequency signals.
Image reconstruction.
4
Types of MRI Scans
Structural MRI Functional MRI (fMRI) Diffusion
MRI Magnetic Resonance Spectroscopy (MRS)

THE ROLE OF NOISE
Introduction to Noise in MRI Noise Unwanted sign
als or interference. Presence of noise in MRI
scans. Sources of Noise Thermal noise Patient
motion Electronic components Radiofrequency
interference
6
TYPES OF NOISE
Thermal Noise Arises due to thermal motion of
particles. Radiofrequency Interference External
sources causing signal disruption. Instrumentation
Noise Originates from the MRI machine's
components
7
Impact of Noise on Image Quality
Effects of Noise on Image Clarity Reduced image
resolution. Distorted anatomy. Challenges in
accurate diagnosis.
8
Noise Reduction Techniques
Minimizing patient movement. Patient comfort and
instructions. Advanced gradient coils and
shielding. RF shielding and filtering. Noise
filtering algorithms. Reconstruction techniques.
Pre-scan Preparations Hardware
Improvements Signal Processing
