The International Day of Radiology (IDoR) is celebrated annually on November 8th to promote the role of medical imaging in modern healthcare and mark the anniversary of the discovery of x-rays on November 8th 1895 by Wilhelm Conrad Röntgen, who effectively layed the foundation for the new medical discipline of radiology.
Radiology is the medical specialty that uses medical imaging to diagnose and treat diseases within the body.A variety of imaging techniques such as X-ray radiography, ultrasound, computed tomography (CT), nuclear medicine including positron emission tomography (PET), and magnetic resonance imaging (MRI) are used to diagnose or treat diseases. Interventional radiology is the performance of (usually minimally invasive) medical procedures with the guidance of imaging technologies.
The modern practice of radiology involves several different healthcare professions working as a team. The Radiologist is a medical doctor who has completed the appropriate post-graduate training and interprets medical images, communicates these findings to other physicians by means of a report or verbally, and uses imaging to perform minimally invasive medical procedures. The Nurse is involved in the care of patients before and after imaging or procedures, including administration of medications, monitoring of vital signs and monitoring of sedated patients. The Radiographer, also known as a “Radiologic Technologist” in some countries, is a specially trained healthcare professional that uses sophisticated technology and positioning techniques to acquire medical images. Depending on the individual’s training and country of practice, the radiographer may specialize in one of the above-mentioned imaging modalities or have expanded roles in image reporting.
The International Day of Radiology was first introduced in 2012, as a joint initiative, by the European Society of Radiology (ESR), the Radiological Society of North America (RSNA), and the American College of Radiology (ACR). The International Day of Radiology is a successor to the European Day of Radiology which was launched in 2011. The first and only European Day of Radiology was held on February 10, 2011 to commemorate the anniversary of Röntgen’s death. The European day was organised by the ESR, who later entered into cooperation with the RSNA and the ACR to establish the International Day of Radiology.
The International Day of Radiology marks the anniversary of Röntgen’s discovery of x-rays and the main theme was medical imaging in oncology. The day was celebrated with events in many countries, mostly organised by national professional societies which represent radiologists. Many public lectures on the role of imaging in oncology took place across Europe. In the UK, the Royal College of Radiologists organised a free public lecture at the Wellcome Collection by Dr. Phil O’Connor, who served as head of musculoskeletal imaging at the London 2012 Olympics. The ESR also published two booklets to mark the occasion, ‘The Story of Radiology’, which was created in cooperation with the International Society for the History of Radiology, and ‘Making Cancer Visible: the role of cancer in oncology’
World Radiography Day also takes place to mark the anniversary of the discovery of X-rays in 1895. The purpose of this day is to raise public awareness of radiographic imaging and therapy, which play a crucial role in the diagnosis and the treatment of patients and, most importantly, ensuring radiation is kept to the minimum required, hence improving the quality of patient care. The day is celebrated worldwide by various national radiographers’ associations and societies, including Nigeria’s Association of Radiographers of Nigeria, United Kingdom’s Society of Radiographers (SoR), among others. The International Society of Radiographers and Radiological Technologists have celebrated 8 November as World Radiography Day since 2007.
German mechanical engineer and physicist Wilhelm Konrad Röntgen was born 27 March 1845. He attended high school in Utrecht, Netherlands. However In 1865, he was expelled from high school and Without a high school diploma, Röntgen could only attend university in the Netherlands as a visitor. In 1865, he tried to attend Utrecht University without having the necessary credentials required for a regular student. Upon hearing that he could enter the Federal Polytechnic Institute in Zurich (today known as the ETH Zurich), he passed its examinations, and began studies there as a student of mechanical engineering. In 1869, he graduated with a Ph.D. from the University of Zurich; once there, he became a favorite student of Professor August Kundt, whom he followed to the University of Strassburg.
In 1874, Röntgen became a lecturer at the University of Strassburg. In 1875, he became a professor at the Academy of Agriculture at Hohenheim, Württemberg. He returned to Strassburg as a professor of physics in 1876, and in 1879, he was appointed to the chair of physics at the University of Giessen. In 1888, he obtained the physics chair at the University of Würzburg, and in 1900 at the University of Munich, by special request of the Bavarian government. Although Röntgen accepted an appointment at Columbia University in New York City the outbreak of World War I changed his plans and he remained in Munich for the rest of his career.
During 1895, Röntgen was investigating the external effects from the various types of vacuum tube equipment — apparatuses from Heinrich Hertz, Johann Hittorf, William Crookes, Nikola Tesla and Philipp von Lenard — when an electrical discharge is passed through them. In early November, he was repeating an experiment with one of Lenard’s tubes in which a thin aluminium window had been added to permit the cathode rays to exit the tube but a cardboard covering was added to protect the aluminium from damage by the strong electrostatic field that produces the cathode rays. He knew the cardboard covering prevented light from escaping, yet Röntgen observed that the invisible cathode rays caused a fluorescent effect on a small cardboard screen painted with barium platinocyanide when it was placed close to the aluminium window. It occurred to Röntgen that the Crookes–Hittorf tube, which had a much thicker glass wall than the Lenard tube, might also cause this fluorescent effect.
On 8 November 1895, Röntgen decided to test his idea. He carefully constructed a black cardboard covering similar to the one he had used on the Lenard tube. He covered the Crookes–Hittorf tube with the cardboard and attached electrodes to a Ruhmkorff coil to generate an electrostatic charge. Before setting up the barium platinocyanide screen to test his idea, Röntgen darkened the room to test the opacity of his cardboard cover. As he passed the Ruhmkorff coil charge through the tube, he determined that the cover was light-tight and turned to prepare the next step of the experiment. It was at this point that Röntgen noticed a faint shimmering from a bench a few feet away from the tube. To be sure, he tried several more discharges and saw the same shimmering each time. Striking a match, he discovered the shimmering had come from the location of the barium platinocyanide screen he had been intending to use next.
Röntgen speculated that a new kind of ray might be responsible. 8 November was a Friday, so he took advantage of the weekend to repeat his experiments and made his first notes. In the following weeks he ate and slept in his laboratory as he investigated many properties of the new rays he temporarily termed “X-rays”, using the mathematical designation (“X”) for something unknown. The new rays came to bear his name in many languages as “Röntgen rays” (and the associated X-ray radiograms as “Röntgenograms”). At one point while he was investigating the ability of various materials to stop the rays, Röntgen brought a small piece of lead into position while a discharge was occurring. Röntgen thus saw the first radiographic image, his own flickering ghostly skeleton on the barium platinocyanide screen. He later reported that it was at this point that he determined to continue his experiments in secrecy, because he feared for his professional reputation if his observations were in error.
Nearly two weeks after his discovery, he took the very first picture using X-rays of his wife Anna Bertha’s hand. When she saw her skeleton she exclaimed “I have seen my death!” Röntgen’s original paper, “On A New Kind Of Rays” (Ueber eine neue Art von Strahlen), was published on 28 December 1895. On 5 January 1896, an Austrian newspaper reported Röntgen’s discovery of a new type of radiation. Röntgen was awarded an honorary Doctor of Medicine degree from the University of Würzburg after his discovery. He published a total of three papers on X-rays between 1895 and 1897. Today, Röntgen is considered the father of diagnostic radiology, the medical speciality which uses imaging to diagnose disease. A collection of his papers is held at the National Library of Medicine in Bethesda, Maryland.
