Drawbacks of Traditional MRI Machines

• Magnetic Resonance Imaging (MRI) is a
  non-invasive imaging technique that provides
  detailed images of the body. It is used to
  diagnose a variety of medical conditions. MRI is
  based on the principles of nuclear magnetic
  resonance (NMR), which is a branch of physics
  that deals with the magnetic properties of atoms.
  The technique uses strong magnetic fields and
  radio waves to create detailed images of the
  body. MRI is an imaging technique that uses
  strong magnetic fields and radio waves to create
  detailed images of the human body. It is
  primarily used in medical settings to get
  high-resolution images of the inside of the human
  body. MRI scanners use magnetic fields and radio
  waves to obtain cross-sectional images of the
  human body. The technique does not use ionizing
  radiation. MRI is considered a noninvasive and
  painless procedure. It is primarily used to
  diagnose and monitor medical conditions. MRI is
  also used to monitor the effectiveness of certain
  medical treatments, such as surgery and radiation
  therapy.

Principles of NMR

• Magnetic Resonance Imaging (MRI) is based on the
  principles of nuclear magnetic resonance (NMR),
  which is a branch of physics that deals with the
  magnetic properties of atoms. NMR is used to
  study the structure and properties of molecules.
  In MRI, strong magnetic fields are used to align
  the protons in the body, and radio waves are then
  used to disturb the protons, which in turn sends
  out signals that are picked up by a scanner. The
  signals are then used to create images of the
  body.

How MRI Works

• MRI scanners use magnetic fields and radio waves
  to obtain cross-sectional images of the human
  body. The technique does not use ionizing
  radiation. MRI is considered a noninvasive and
  painless procedure. It is primarily used to
  diagnose and monitor medical conditions. MRI is
  also used to monitor the effectiveness of certain
  medical treatments, such as surgery and radiation
  therapy. The technique is particularly useful for
  examining soft tissue, such as the brain and
  spinal cord, which are difficult to image using
  other techniques. MRI is also used to examine
  bones and joints.

Safety Concerns

• MRI is considered to be a safe and painless
  procedure. However, the powerful magnetic fields
  and radiofrequency waves used in the procedure
  can affect implanted medical devices and can also
  cause burns. Strong magnetic fields can also
  affect medical devices that use electricity.

Limitations of Traditional MRI
Traditional MRI machines have several
limitations, including their size and cost. They
often require patients to be placed inside a
small, enclosed space for an extended period of
time, which can cause discomfort and anxiety.
5
Open MRI

• Open MRI machines are designed to be more
  comfortable for patients and can accommodate
  larger patients. They offer increased patient
  comfort and reduced anxiety.

• ?

High Field MRI
High field MRI machines use stronger magnetic
fields to provide even more detailed images of
the body. They are particularly useful in
detecting smaller lesions and abnormalities.
6
Functional MRI

• Functional MRI is a specialized form of MRI that
  measures changes in blood flow in the brain. It
  is particularly useful in examining brain
  function and mapping brain activity.

• ?

MRI Contrast Agents
MRI contrast agents are substances injected into
the body to improve the visibility of certain
tissues or structures on MRI scans. They work by
altering the magnetic properties of the tissues
or structures.

Emerging MRI Technologies

• Emerging MRI technologies, including molecular
  imaging and real-time MRI, are advancing the
  field of MRI and expanding its potential
  applications.

Limitations and Future Directions
Despite its many benefits, MRI technology still
has limitations. We will discuss the current
limitations of MRI technology and the potential
future directions of MRI research, including the
development of new imaging techniques and
improved safety features.

Conclusion

• In this presentation, we have discussed the
  benefits and limitations of traditional MRI
  machines, the advantages of open and high-field
  MRI, and emerging MRI technologies. We have
  offered insights into the future of MRI research
  and potential improvements in patient care.
