Title: The Evolution of Imaging Technology

  • Ever since Wilhelm Conrad Röntgen invented the
    X-ray machine, winning the Nobel Prize in Physics
    for its discovery in 1901, imaging technology has
    evolved and grown to assume a greater role in the
    practice of medicine.
  • As the safety and sophistication of radiology
    imaging services improve, these advanced machines
    have changed the way medicine is practiced.
  • Beyond direct, doctor-to-patient verbal
    communication, machines add an in-between layer
    of information and intelligence.1

3
  • Doctors determine what steps to take in order to
    diagnose and treat symptoms, often with the aid
    of one or more radiology services.
  • The various radiology machines create close-up
    patient information in the form of images which
    the doctor uses to diagnose and analyze illness.
  • Advanced radiology methods allow doctors to see
    further inside the mysteries of the complex human
    organism, detecting signs of trouble at a much
    earlier stage, and with more accuracy.
  • Appropriate treatment can be applied before an
    illness progresses too far, often resulting in
    better health outcomes.

4
  • Radiology imaging services have become an
    essential tool, relied on for potentially
    life-saving benefits through services of a
    radiologist online, in second opinion diagnoses,
    and primary read diagnostics.
  • Mammography and sonography are the most
    frequently used diagnostic radiology methods,
    forming a cornerstone for much of the current
    practice of womens medicine.
  • Mammography is primarily a wellness screening
    method to detect breast cancer, and sonography
    (or ultrasound) uses sound waves to take pictures
    of the human body, including the fetus in
    utero."2

5
  • Radiology scans continue to evolve as diagnostic
    tools that reveal the bodys inner structures.
    Specialized doctorsdiagnostic radiologistsinterp
    ret the scans, playing an essential role in
    screening for illness, assessing the progress of
    a disease, or measuring the impact of a treatment
    program.
  • New technologies arise, and existing ones are
    re-imagined into more effective methodologies.
  • Some of the most commonly used methods today
    include X-rays, CT scans, PET scans, and MRIs.

6
  • The X-ray image, which allowed doctors to see
    inside the human body non-invasively for the
    first time, is still used today. Doctors have
    learned more about the risks of over-exposure to
    X-rays, leading to development of more controlled
    methods and better protocols for limiting
    exposure over a patients lifetime.
  • Computed Axial Tomography (CAT or CT) Scans The
    combined use of X-rays with computer technologies
    to see anatomical changes, these are often
    applied in angiography to examine the health of
    blood vessels.

7
  • Positron Emission Tomography (PET) Scanning PET
    scans use nuclear medicine, injecting a small
    amount of radioactive material into the veins.
    The scan captures any metabolic changes in organs
    or tissue2, indicating the presence of cancer at
    a much earlier stage than tumor formation.
  • PET/CT Scans The combination of anatomical
    information (from a CT scan), together with the
    metabolic information (from the PET Scan), gives
    a more complete, accurate picture of patient
    health.

8
  • Magnetic Resonance Imaging (MRI) MRI uses a
    large magnetic field and radio waves to create
    complex images of the affected areas.
  • Advantages include the total lack of radiation
    exposure or of any known side effects. A great
    disadvantage has been the discomfort felt by
    claustrophobic patients due to the small,
    enclosed, tube-like space in which the MRI is
    administered. The advent of newer, Open MRI
    machines and shorter machines has improved the
    patient experience and reduced claustrophobic
    effects.

9
  • Proper analysis and interpretation of
    sophisticated radiology scans is a highly
    specialized medical field with dramatic potential
    consequences for patients. Obtaining a second
    opinion analysis can be a life-saving step when
    results are inconclusive, when patients have
    reason to question their doctors diagnosis, or
    whenever serious illness is involved.
  •  Studies have shown that second opinion diagnoses
    of radiology scans can reveal initial errors of
    interpretation and eliminate unnecessary
    procedures.
  • The radiologist interacts directly with the
    patient, communicating difficult concepts more
    clearly, and often, improving peace of mind along
    with health outcomes.3
