"Medical imaging is the technique and process of imaging the interior of a body for clinical analysis and medical intervention."
The interpretation of radiographic images to diagnose medical conditions.
Anatomy: Knowledge of human anatomy is essential for interpreting radiographic images. Understanding different body systems and their structures can help in identifying abnormalities or injuries seen in images.
Physiology: A basic understanding of physiological processes and how they affect the body can be useful in radiology. For example, knowing how different organs function can help in identifying changes in radiographic images.
Radiographic technique: Understanding the different types of radiographic techniques and how they are performed can help in interpreting images. Knowledge of exposure settings, film processing techniques, and image quality evaluation is also necessary in radiology.
Terminology: Radiology has its own set of technical terms and abbreviations, which must be learned for effective communication in the field.
Radiographic anatomy: This topic covers the appearance of normal anatomical structures on radiographic images.
Radiographic positioning: This involves different techniques used to position patients during radiographic imaging for improved image quality and exposure.
Radiographic pathology: This topic involves the recognition and interpretation of abnormal radiographic images, including different types of pathologies, injuries, and other changes.
Imaging modalities: There are various types of imaging modalities used in radiology, such as X-rays, CT scans, MRIs, and ultrasound. Understanding the principles and differences between these modalities is important when interpreting images.
Radiology safety: Radiation safety, patient safety, and occupational safety are crucial factors to consider in radiology, and understanding the guidelines and precautions is necessary for proper practice.
Quality assurance: This topic involves evaluating and monitoring the quality of radiographic images produced, ensuring that they meet certain standards for diagnostic accuracy.
Radiology reporting: This involves communicating the results of radiographic examinations to other medical professionals and patients. Skills in report creation, documentation, and communication are needed to convey accurate and relevant information.
Professionalism: Being professional and ethical in radiology is important, including skills in patient care, communication, and interdisciplinary teamwork. A strong work ethic is also required for maintaining a high level of performance in the field.
X-ray Radiography: Uses electromagnetic radiation to produce images of dense tissues such as bones in the body.
Computed Tomography (CT): Combines X-rays with computer technology to produce more detailed images of body tissues.
Magnetic Resonance Imaging (MRI): Uses a strong magnetic field and radio waves to produce images of body tissues.
Ultrasound: Uses high-frequency sound waves to produce images of internal body structures.
Nuclear Imaging: Uses radiopharmaceuticals to produce images of body tissues.
Fluoroscopy: Uses X-rays to produce real-time moving images of body tissues.
Mammography: Specialized X-ray imaging used to image breast tissue for detection of breast cancer.
Angiography: Uses X-rays to image blood vessels in the body.
Positron Emission Tomography (PET): Uses a radiotracer to produce images of metabolic activities of body tissues.
Digital Radiography (DR): A type of X-ray imaging where the image is produced digitally and can be manipulated using software.
"Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease."
"Medical imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities."
"Electroencephalography (EEG), magnetoencephalography (MEG), electrocardiography (ECG), and others."
"These technologies can be considered forms of medical imaging in another discipline of medical instrumentation."
"As of 2010, 5 billion medical imaging studies had been conducted worldwide."
"Radiation exposure from medical imaging in 2006 made up about 50% of total ionizing radiation exposure in the United States."
"Medical imaging equipment is manufactured using technology from the semiconductor industry, including CMOS integrated circuit chips, power semiconductor devices, sensors, and processors."
"As of 2015, annual shipments of medical imaging chips amount to 46 million units."
"In the case of medical ultrasound, the probe consists of ultrasonic pressure waves and echoes that go inside the tissue to show the internal structure."
"The term 'noninvasive' is used to denote a procedure where no instrument is introduced into a patient's body."
"No instrument is introduced into a patient's body, which is the case for most imaging techniques used."

"Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease."
"Medical imaging also establishes a database of normal anatomy and physiology to make it possible to identify abnormalities."
"Although imaging of removed organs and tissues can be performed for medical reasons, such procedures are usually considered part of pathology instead of medical imaging."
"Measurement and recording techniques, such as electroencephalography (EEG), magnetoencephalography (MEG), electrocardiography (ECG), and others."
"In the case of projectional radiography, the tube uses X-ray radiation."
"X-ray radiation is absorbed at different rates by different tissue types such as bone, muscle, and fat."
