Radiology (at Wikipedia)
Radiology is the branch or speciality of medicine that deals with the study and application of imaging technology like x-ray and radiation to diagnosing and treating disease.
Originally it was the aspect of medical science dealing with the use of electromagnetic energy emitted by X-ray machines or other such radiation devices for the purpose of obtaining visual information as part of medical imaging. Radiology that involves use of x-ray is called roentgenology. The modern day radiological imaging is no longer limited to the use of x-rays, and now includes technology-intensive imaging with high frequency sound waves, magnetic fields, and radioactivity.
Wilhelm Conrad Röntgen (English spelling Roentgen) first discovered x-radiation on 8 November 1895 at the Physical Institute of Würzburg University.[1] He named the radiation he had discovered "X-radiation". This term is still in use today in the Anglo-American region. His work was first published in a meeting protocol of the Würzburg Physical-Medical Society in the 1895 volume; the article was submitted by W.C. Röntgen on 28 December 1895. Roentgen received the first Nobel Prize for Physics for the discovery of X-rays in 1901.
Today, following extensive training, radiologists direct an array of imaging technologies (such as ultrasound, computed tomography (CT) Computer Assisted Tomography, nuclear medicine, Positron Emission Tomography (PET) and magnetic resonance imaging (MRI)) to diagnose or treat disease. Interventional radiology is the performance of (usually minimally invasive) medical procedures with the guidance of imaging technologies. The acquisition of medical imaging is usually carried out by the radiographer or radiologic technologist. Outside of the medical field, radiology also encompasses the examination of the inner structure of objects using X-rays or other penetrating radiation
Radiology
Radiology is the branch of medicine that uses radioactive substances, electromagnetic radiation and sound waves to create images of the body, its organs and structures for the purpose of diagnosis and treatment. Images can also show how effective the body and its internal organs and structures are functioning.
Radiology was discovered a little over 100 years ago and has evolved into a high-tech science with state-of-the-art equipment to aid in imaging every aspect of the body.
While, there has been concern over the potential harmful side effects associated with the use of radiation, it is believed that the small risks are greatly outweighed by the information gained about patients' conditions and the contribution to medical science.
Radiology offers both diagnostic and therapeutic services. The following specialty areas of radiology include:
Diagnostic Radiology - An area of radiology that uses external radiation to produce images of the body, its organs, and other internal structures for medical diagnostic purposes.
Nuclear Medicine - A specialized area of diagnostic radiology that uses very small amounts of radioactive materials to create an image of the body, its organ functions and structure, for diagnostic and treatment purposes.
Therapeutic Radiology (Radiation Oncology) - A specialized area of radiology that uses applications of radiant energy to study, treat, and manage cancer and other diseases.
Interventional Radiology - A specialized area of radiology that uses various imaging techniques to guide the insertion of small instruments and tools through the body to identify and treat a medical disorder without requiring conventional surgery.
Therapeutic Radiology (Radiation Oncology)
Therapeutic radiology (also called radiation oncology) is the treatment of cancer and other diseases with radiation. High energy x-rays are used to kill the cancer cells by preventing them from multiplying. Therapeutic radiology may be used to cure or control cancer, or to alleviate some of the symptoms associated with cancer.
The level of radiation will be determined by the radiation oncologist based on the type of cancer, location of the tumor, and sensitivity of the surrounding tissue.
Although each hospital may have specific protocols in place, generally, radiation oncology procedures follow this process:
Simulation - to help set up the actual treatment, the treatment team first "maps" out the position the patient will be in for each treatment with the aid of molds, headrests, or other devices. Sometimes the area on the body to be treated will be marked to ensure the radiation will be given in the exact area. In addition, special shields may be made to help focus the radiation and protect surrounding tissue.
Treatment plan - once the simulation has taken place, the radiation oncologist will determine the exact type of treatment.
Radiography
Radiographs are image created with X-rays, and used for the evaluation of many bony and soft tissue structures. Fluoroscopy and angiography are special applications of X-ray imaging. Fluoroscopy is a technique where a fluorescent screen or image intensifying tube is connected to a closed-circuit television system to image internal structures of the body. Angiography uses methods to demonstrate the internal structure of blood vessels, highlighting the presence and extent of obstruction to the vessel, if any. In medical imaging, contrast media are substances that are administered into the body, usually injected or swallowed, to help delineate the anatomy of blood vessels, the genitourinary tract, the gastrointestinal tract, etc. Contrast media, which strongly absorb X-ray radiation, in conjunction with the real-time imaging ability of fluroscopy and angiography help to demonstrate dynamic processes, such as the peristalsis of the digestive tract or blood flow.
CT scanning
CT imaging uses X-rays in conjunction with computing algorithms to image tissues in the body. Imaging is usually performed in the axial plane; however, computer reconstructions can be rendered in other planes or to produce 3D images. Contrast media is often used to delineate anatomy and allows 3D reconstructions of structures, such as arteries and veins. Although the resolution of radiographs is higher for imaging of the skeleton, CT can generate much more detailed images of soft tissues. CT exposes the patient to more ionizing radiation.
Sonography
Medical ultrasonography uses ultrasound (high-frequency sound waves) to visualize soft tissue structures in the body in real time. No radiation is involved, but the quality of the images obtained using ultrasound is highly dependent on the skill of the person performing the exam. Ultrasound procedures are best used for ante natal checkups. It is not harmful to fetus nor to the mother.
MRI Magnetic Resonance Imaging
MRI uses strong magnetic fields to align spinning atomic nuclei (usually hydrogen protons) within body tissues, then disturbs the axis of rotation of these nuclei and observes the radio frequency signal generated as the nuclei return to their baseline status. MRI scans give the best soft tissue contrast of all the imaging modalities. With advances in scanning speed and spatial resolution, and improvements in computer 3D algorithms and hardware, MRI has the potential for great development in the next few years. One disadvantage is that the patient has to hold still for long periods of time in a noisy, cramped space while the imaging is performed.
Nuclear medicine
Nuclear medicine imaging involves the administration into the patient of substances labelled with radioactive isotopes which have affinity for particular tissues. Generally speaking, Technecium 99 is the isotope used. The heart, lungs, thyroid, liver, gallbladder, and bones are commonly evaluated for particular conditions using these techniques. While anatomical detail is limited in these studies, nuclear medicine is useful in displaying physiological function. Processes such as the growth of a tumor can be monitored this way, even when the tumor cannot be adequately visualized using any of the other imaging modalities. Nuclear medicine also involves the therapeutic administration of isotopes labeled to antibodies or other substances, therefore delivering a high dose of radiation to specific targets such as tumors or the thyroid gland
Interventional radiology
From Wikipedia, the free encyclopedia
Interventional Radiology (abbreviated IR or sometimes VIR for vascular and interventional radiology) is a subspecialty of radiology in which minimally invasive procedures are performed using image guidance. Some of these procedures are done for purely diagnostic purposes (e.g., angiogram), while others are done for treatment purposes (e.g., angioplasty). Pictures (images) are used to direct these procedures, which are usually done with needles or other tiny instruments like small tubes called catheters. The images provide road maps that allow the Interventional Radiologist to guide these instruments through the body to the areas of interest.
Nuclear medicine
From Wikipedia, the free encyclopedia
Nuclear medicine is a branch of medicine and medical imaging that uses radioactive isotopes (radionuclides) in the diagnosis of disease. Nuclear medicine thus relies on the process of radioactive decay. Molecular imaging may employ nuclear medical techniques when it uses radioisotopes to produce images that reflect biological processes that take place at the cellular and subcellular level.
Nuclear medicine procedures use pharmaceuticals that have been labeled with radionuclides (radiopharmaceuticals). In diagnosis, radioactive substances are administered to patients and the radiation emitted is detected. The diagnostic tests involve the formation of an image using a gamma camera or positron emission tomography, invented by Hal O. Anger, and sometimes called an Anger gamma camera, as well as single photon emission tomography SPECT. Imaging may also be referred to as radionuclide imaging or nuclear scintigraphy. Other diagnostic tests use probes to acquire measurements from parts of the body, or counters for the measurement of samples taken from the patient.
In therapeutic use, radionuclides may be administered to treat disease, or provide palliative pain relief. However, the use of radionuclides in therapy, once a part of classical nuclear medicine, is now often formally merged with the practice of radiotherapy (Radiation therapy medicine), where radionuclides are used by practioners who also employ other sources of radiation. See radiotherapy for discussion of the therapeutic use of radioisotopes.
Nuclear medicical tests differ from most other imaging modalities in that diagnostic tests primarily show the physiological function of the system being investigated as opposed to traditional anatomical imaging such as CT or MRI. In some centers, the nuclear medicine images can be superimposed, using software or hybrid cameras, on images from modalities such as CT or MRI to highlight the part of the body in which the radiopharmaceutical is concentrated. This practice is often referred to as image fusion or co-registration.
Nuclear medicine diagnostic tests are usually provided by a dedicated department within a hospital and may include facilities for the preparation of radiopharmaceuticals. The specific name of a department can vary from hospital to hospital, with the most common names being the nuclear medicine department and the radioisotope department. Nuclear medicine is a technologically embedded speciality that requires collaboration of not only physicians ( nuclear medicine physicians or radiologists), technologists, and support personnel, but also medical physicists, engineers, radiochemists, radiopharmacists, radiobiologists, and instrument manufacturers
