X-rays (X-radiation) are a form of high-energy electromagnetic radiation. In many languages, it is referred to as Röntgen radiation, after the German scientist Wilhelm Conrad Röntgen, who discovered it in 1895 and named it X-radiation to signify an unknown type of radiation.
A computed tomography scan is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists.
Sir Godfrey Newbold Hounsfield was a British electrical engineer who shared the 1979 Nobel Prize for Physiology or Medicine with Allan MacLeod Cormack for his part in developing the diagnostic technique of X-ray computed tomography (CT).
Dural ectasia is widening or ballooning of the dural sac surrounding the spinal cord. This usually occurs in the lumbosacral region, as this is where the cerebrospinal fluid pressure is greatest, but the spinal canal can be affected in any plane.
A coronary CT calcium scan is a computed tomography (CT) scan of the heart for the assessment of severity of coronary artery disease. Specifically, it looks for calcium deposits in atherosclerotic plaques in the coronary arteries that can narrow arteries and increase the risk of heart attack. These plaques are the cause of most heart attacks, and become calcified as they develop.
In medicine, the Golden S sign is a sign seen on imaging of the chest that suggests a central lung mass or lung collapse. It was first described by Dr. Ross Golden (1889-1975) in 1925 in association with bronchial carcinoma, but it is also seen in metastatic cancer, enlarged lymph nodes, and collapse of the right upper lobe of the lung.
Aortography involves placement of a catheter in the aorta and injection of contrast material while taking X-rays of the aorta. The procedure is known as an aortogram. The diagnosis of aortic dissection can be made by visualization of the intimal flap and flow of contrast material in both the true lumen and the false lumen. The catheter has to be inserted through the right femoral artery, because in about two-thirds of cases the aortic dissection spreads into the left common iliac artery.
The American Journal of Roentgenology (AJR) is a monthly peer-reviewed journal that covers topics in radiology. It is published by the American Roentgen Ray Society (ARRS) and is based in Leesburg, VA. The current editor-in-chief is Andrew B. Rosenkrantz.
Thomas M. Kolb is an American radiologist specializing in the detection and diagnosis of breast cancer in young, predominantly high-risk premenopausal women. He has served as an assistant clinical professor of Radiology at Columbia University College of Physicians and Surgeons from 1994–2010. Kolb is double board certified, having received his training in pediatrics at the Albert Einstein College of Medicine in Bronx, New York, and in diagnostic radiology at the Columbia-Presbyterian Medical Center in New York.
The British Institute of Radiology (BIR) is a radiology society and charity based in London, United Kingdom. It is the oldest institute of its kind in the world, forming on 2 April 1897.
Steve Webb is a British medical physicist and writer. He is an emeritus professor of physics at the Joint Department of Physics in the Institute of Cancer Research and the Royal Marsden Hospital. He was editor-in-chief of Physics in Medicine and Biology for six years, being succeeded in 2011 by Simon Cherry.
Madan M. Rehani is an Indian-born medical physicist.
Ákos Géza Kovács was an internationally renowned Hungarian radiologist.
Charles Thurstan Holland was an English general practitioner in Liverpool who was best known by his pioneering research in the field of radiology. The Thurstan Holland sign is named after him.
Elizabeth Fleischman-Aschheim was an American radiographer who is considered an X-ray pioneer. Fleischman was the first woman to die as a result of X-ray radiation exposure.
Dawson Fyers Duckworth Turner, FRSE, FRCPE (1857–1928) was a British pioneer of radiology and patron of the arts, who died of radiation related cancer.
Dr John Haybittle was a British medical physicist.
Ronald Marc Summers is an American radiologist and senior investigator at the Diagnostic Radiology Department at the NIH Clinical Center in Bethesda, Maryland. He is chief of the Clinical Image Processing Service and directs the Imaging Biomarkers and Computer-Aided Diagnosis (CAD) Laboratory. A researcher in the field of radiology and computer-aided diagnosis, he has co-authored over 500 journal articles and conference proceedings papers and is a coinventor on 12 patents. His lab has conducted research applying artificial intelligence and deep learning to radiology.
Brian Worthington was the first radiologist to be elected a Fellow of the Royal Society and is acknowledged as a pioneer in clinical magnetic resonance imaging. He was born in Oldham, England and was educated at Hulme Grammar School, training at Guy's Hospital after graduating in physiology and medicine. After graduation his career developed rapidly, particularly in the field of MRI research and he was subsequently admitted as a Fellow of the Royal College of Radiologists.
Sydney Domville Rowland was an English physician and the world's first editor of a radiology journal. He coined the term "skiagraphy" and wrote some of the first works on X-rays in the Archives of Clinical Skiagraphy that preceded the British Journal of Radiology.
