Radiology – Technology to Diagnose and Treat

 Since the Nobel winning discovery of X-rays and Radiographs by Wilhelm Conrad Röntgen, a number of medical tools have been developed for the aid of medical diagnostics and treatment. Radiology as a medical specialty involves the use of medical imaging and radiation therapy, to diagnose and treat diseases through visualization of the body.

Among the technologies developed in the past century, but still in use to diagnose and treat are:

  • X-ray radiography – also called radiographs or roentgenographs, transmit X-rays through a patient and a filtering device to a film.
  • Fluoroscopy – special application of X-ray imaging, which uses a fluorescent screen connected to a TV system to allow real-time imaging. It requires radiocontrast agents administered to patients to delineate the anatomy.
  • Ultrasound – Using high frequency sound waves, which make the visualization of tissue structures possible.
  • Computed tomography – uses X-rays and computer algorithms to generate and image.
  • Magnetic Resonance Imaging (MRI) – Uses magnetic fields and radio signals to produce oblique planes.

Other techniques are Nuclear Medicine, Positron Emission Tomography (PET), Mammography and Teleradiology.

As high-quality imaging equipment and technological advances are becoming available at a higher rate, medical specialists can offer interventional radiology and more treatment options to more patients.

Some of the radiology treatments available thanks to these technologies are:

  • Projection Radiography: Assist in the treatment of congenital skeletal anomalies, bone tumors, arthritis, pneumonia, fractures, etc.
  • Fluoroscopy: Help treat tumors, inflammation, orthopedic surgery, leg, heart and brain vessels, urological surgery, discography
  • Ultrasound: this procedure can presage strokes, is used is biobsies, can assess the presence of hemorrhage.
  • X-ray computed tomography: Used to diagnose and assess treatments on the head, lungs, pulmonary angiogram, cardiac treatments, abdominal and pelvic issues and extremities.
  • Magnetic resonance imaging: an important tool for radiology treatments in musculoskeletal issues and in neuroradiology.
