Medical technology has evolved endlessly in the past few years. With a machine, one can see what is going inside their body so easily. With the introduction of Artificial Intelligence and machine learning, there is limitless potential for medical technology to grow exponentially. To monitor, and diagnose any injury or disease. The diagnosis of cardiovascular diseases, cancer, internal bleeding, and other complications has gotten extremely efficient and easy because of the non-invasive methods of medical imaging that we use today. In this article, we will read about different types of medical imaging and the facts about them.
What is medical imaging?
It is a method for doctors to examine, monitor, and diagnose ailments and complications in the body of the patient. This is possible because imaging provides the doctors with a view of the internal structure of the patient. Some but not all imaging include the use of radiation. Types of imaging include:
Computed Tomography
Ultrasound
Mammography
Cardiac-Interventional Radiography
Vascular-Interventional Radiography
Magnetic Resonance
Sonography
Angiography
The First Radiation Imaging
Wilhelm Conrad Röntgen, a German physicist and engineer, discovered and produced the use of electromagnetic radiation in a wavelength range known as X-rays or Röntgen rays in medical imaging, in the year 1895. The first-ever X-Ray was captured by Röntgen of her wife’s hand. Röntgen earned his Nobel Prize for his revolutionizing discovery and invention. The clinical use of X-Rays started to occur from the following year. It was immediately adopted and widely used.
Fun fact: Madam Curie would design vehicles especially to transport these X-Ray machines to battlefields during World War I
Sound Imaging
Ultrasound imaging uses different waves of sounds to produce pictures of the inner structure of the body. It is used to help diagnose and examine the causes of pain, swelling, and infection in the body's internal linings and organs. Also to monitor and examine the fetus inside pregnant women and the brain and hips in infants. It's also used as a guide for biopsies, diagnosis of cardiovascular diseases, and assessment of the damage after a heart attack. Ultrasound is safe, non-invasive, and does not use ionizing radiation.
Fun Fact: Ultrasound was adapted from the same technology used for SONAR used in oceans.
Magnetic Waves Imaging
Magnetic resonance imaging (MRI) is a medical imaging technique that involves the usage of a magnetic waves field and computer-generated radio waves for the creation of detailed images of the internal structure of our body like tissues and organs. When you lie inside the MRI tube machine, the magnet realigns the cells in the body and the radio waves force these aligned cells to pass faint signals that cause the imaging of the internal structure. MRI is the most frequently used imaging test of the brain and spinal cord.
Fun Fact: MRI images are three-dimensional that help the doctors to view the image from different angles.
