• Abcedography / Radiography of an abscess — A specialized radiological technique consisting of taking an X-ray of an abscess cavity, performed immediately following its puncture, evacuation of pus, and subsequent injection of a contrast medium or air to delineate its size, contours, and extension.
• Actinocardiography — A rare technical or historical medical term defining a graphical method of recording or visualizing the activity and movements of the heart using radiation (X-rays or radioactive tracers). This early structural technique, a precursor to modern angiocardiography and advanced nuclear medicine methods, allowed physicians in the last century to obtain crude visual data regarding the outline and dynamics of cardiac chambers during the systolo-diastolic cycle.
• Actinography — A historical medical and scientific term used in the past as a synonym for radiography or the technique of obtaining internal structural images of solid bodies using X-rays or other active radiant beams. In old applied physics, it also defined the general method of printing or recording onto a photosensitive film the chemical effects directly caused by exposure to an electromagnetic wave flux within the ultraviolet spectrum.
• Actinoscopy — A historical medical term used in the past to designate fluoroscopy or radioscopy; a method of direct, real-time visual examination of the internal structures of the human body by projecting radiological shadows onto a fluorescent screen under the action of X-rays. This early structural technique allowed physicians in the last century to observe organ movements (such as heart pulsations or lung respiration) without developing a photographic plate.
• Adenography — An imaging method or radiological investigation technique that allows the structural visualization and detailed examination of the glandular system or lymph nodes. This medical procedure is typically performed by introducing a radiopaque contrast medium into the efferent lymphatic vessels, followed by taking successive X-rays to detect abnormalities such as tumors, structural blockages, or chronic inflammation.
• Aerocystography — A radiological method for investigating the urinary bladder consisting of performing radiographs after the bladder cavity has been distended by insufflating a controlled amount of air or another sterile gas. This imaging examination highlights the contour of the bladder walls, detecting radiolucent tumors, calculi, or diverticula, functioning as a negative contrast medium.
• Aerophotography — The technique of photographing the Earth's surface from high above, using special photographic cameras mounted on board airplanes, helicopters, satellites, or drones; the photographic image obtained through this process. It is widely used in topography, archaeology, meteorology, military espionage, and urban planning.
• Aeromammography — A historical radiological method or experimental imaging technique for examining the mammary gland, consisting of performing radiographs after the controlled introduction or insufflation of air or another sterile gas as a negative contrast medium into the periglandular tissues or milk ducts, used to highlight tumors before the advent of modern digital mammography.
• Aerosialography — A radiological method of clinical investigation consisting of the examination of salivary glands and their excretory ducts by controlled injection of a small volume of air or gas as a negative contrast medium, followed by successive radiographs. This structural procedure enables the visualization of anatomical shapes, non-stereotypical salivary stones, or potential obstructions without using liquid iodinated substances.
• Aerouretroscope — A precision urological medical instrument used for the direct visual examination of the interior of the urethra, structurally designed to allow the controlled insufflation of air or gas to dilate the urinary lumen and facilitate mucosa visualization. This technical device enables the diagnosis of strictures, cysts, or other specific urethral pathologies.
• Amidotrizoate — An iodinated organic compound with an aromatic structure, clinically used as a water-soluble, high-osmolality radiological contrast agent, also known as diatrizoate. Due to the high number of iodine atoms in its molecule, it strongly absorbs X-rays, facilitating clear structural visualization of blood vessels, the urinary tract (urography), and the gastrointestinal system during diagnostic imaging investigations.
• Amniography — A specialized clinical or historical radiological method of examining the uterine cavity and the fetus, consisting of injecting a radiopaque contrast medium directly into the amniotic fluid, followed by X-rays. It was used to delineate fetal contours, locate the placenta, or detect macroscopic malformations prior to the widespread use of modern ultrasound.
• Anechoic — Pertaining to anatomical structures, tissues, cysts, or tumor masses that produce no echoes during ultrasound examination, appearing completely black on the screen; anechoic or echo-free. This structural physical trait indicates a purely fluid-filled mass.
• Aneurysmal — Belonging to an aneurysm, referring to an aneurysm, or presenting the structural and clinical characteristics of a pathological arterial dilation. This specialized descriptive term is used to define the nature of a vascular pouch, changes in the wall of a blood vessel, or symptoms associated with an ectasia.
• Angio — A shortened form used colloquially in clinical environments for angiography or angio-MRI / angio-CT, or a primary scientific combining element indicating a direct link to blood vessels (arteries, veins) or lymphatic vessels. As an independent lexical entity in medical jargon, it denotes the high-resolution imaging investigation capable of structurally visualizing the lumen and circulatory flow of the vascular system.
• Angiocardiograph — A high-performance medical device used in radiology and interventional cardiology for the visualization and structural recording of images of the heart cavities and great blood vessels. This complex apparatus integrates advanced X-ray or digital fluoroscopy scanning systems, allowing real-time capturing of the transit of an injected contrast medium, making it essential for diagnosing stenoses and cardiac malformations.
• Angiocardiography — A radiological imaging investigation method consisting of visualizing and recording on film or digital media the heart cavities and great blood vessels, through the introduction of a contrast medium via a catheter. This clinical structural procedure is essential in cardiology for evaluating circulatory dynamics, detecting aneurysms or septal defects, and establishing surgical indications.
• Angiocardiogram — A graphical representation, radiological image, or digital recording of the heart cavities and great blood vessels, obtained following an angiocardiography with a contrast medium. This clinical diagnostic structural element allows specialist physicians to analyze with three-dimensional precision the vascular lumen diameter, bloodstream dynamics, and potential structural defects or congenital cardiac malformations.
• Angiiopardiopneumography — A highly specialized radiological imaging investigation method that allows the structural visualization and recording, using a contrast medium, of the cardiac cavities, great vessels, and the entire pulmonary vascular network. This complex clinical procedure is utilized for the detailed evaluation of cardiopulmonary hemodynamics and the precise diagnosis of severe conditions such as massive pulmonary thromboembolism or complex congenital vascular malformations.
• Angiocolecistography — A radiological imaging investigation method that allows the structural visualization and recording of the gallbladder and the intrahepatic and extrahepatic biliary tracts, through the administration of a radiopaque contrast medium. This well-defined clinical procedure serves to detect obstructions, gallstones, or anatomical anomalies of the biliary tree, while also evaluating the dynamics of secretion elimination into the duodenum.
