Radiology is the medical discipline that uses medical imaging to diagnose and treat diseases within the bodies of animals and humans. A variety of imaging techniques such as X-ray radiology residency personal statementultrasoundcomputed tomography CTnuclear medicine including positron emission radiology residency personal statement PETfluoroscopyand magnetic resonance imaging MRI are used to diagnose or treat diseases.
Interventional radiology is the performance of usually minimally invasive medical procedures with radiology residency personal statement guidance of imaging technologies such as those mentioned above. The modern practice of radiology involves several different healthcare professions working as a team, radiology residency personal statement. The radiologist is a medical doctor who has completed the appropriate post-graduate training and interprets medical images, communicates these findings to other physicians radiology residency personal statement means of a report or verbally, and uses imaging to perform minimally invasive medical procedures.
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. Radiographs originally called roentgenographs, named after the discoverer of X-raysWilhelm Conrad Röntgen are produced by transmitting X-rays through a patient, radiology residency personal statement.
The X-rays are projected through the body onto a detector; an image is formed based on which rays pass through and are detected versus those that are absorbed or scattered in the patient and thus are not detected.
Röntgen discovered X-rays on November 8, and received the first Nobel Prize in Physics for their discovery in In film-screen radiography, an X-ray tube generates a beam of X-rays, which is aimed at the patient. The X-rays that pass through the patient are filtered through a device called a grid or X-ray filterto reduce scatter, and strike an undeveloped film, which is held tightly to a screen of light-emitting phosphors in a light-tight radiology residency personal statement. The film is then developed chemically and an image appears on the film.
Film-screen radiography is being replaced by phosphor plate radiography but more recently by digital radiography DR and the EOS imaging, radiology residency personal statement. In digital radiography the sensors shape a plate, but in the EOS system, which is a slot-scanning system, a linear sensor vertically scans the patient. Plain radiography was the only imaging modality available during the first 50 years of radiology.
Due to its availability, speed, and lower costs compared to other modalities, radiography is often the first-line test of choice in radiologic diagnosis. Also despite the large amount of data in CT scans, MR scans and other digital-based imaging, there are many disease entities in which the classic diagnosis is obtained by plain radiographs. Examples include various types of arthritis and pneumonia, bone tumors especially benign bone tumorsfractures, congenital skeletal anomalies, and certain kidney stones.
Mammography and DXA are two applications of low energy projectional radiography, used for the evaluation for breast cancer and osteoporosisrespectively. Fluoroscopy and angiography are special applications of X-ray imaging, in which a fluorescent screen and image intensifier tube is connected to a closed-circuit television system. Radiocontrast agents are usually administered by swallowing or injecting into the body of the patient to delineate anatomy and functioning of the blood vessels, the genitourinary systemor the gastrointestinal tract GI tract.
Two radiocontrast agents are presently in common use. Barium sulfate BaSO 4 is given orally or rectally for evaluation of the GI tract, radiology residency personal statement. Iodine, in multiple proprietary forms, is given by oral, rectal, vaginal, intra-arterial or intravenous routes.
These radiocontrast agents strongly absorb or scatter X-rays, and in conjunction with the real-time imaging, allow radiology residency personal statement of dynamic processes, such as peristalsis in the digestive tract or blood flow in arteries and veins. Iodine contrast may also be concentrated in abnormal areas more or less than in normal tissues and make abnormalities tumorscystsradiology residency personal statement, inflammation more conspicuous.
Additionally, in specific circumstances, radiology residency personal statement can be used as a contrast agent for the gastrointestinal system and carbon dioxide can be used as a contrast agent in the venous system; in these cases, the contrast agent attenuates the X-ray radiation less than the surrounding tissues.
CT imaging uses X-rays in conjunction with computing algorithms to image the body. CT is acquired in the axial plane, with coronal and sagittal images produced by computer reconstruction. Radiocontrast agents are often used with CT for enhanced delineation of anatomy. Although radiographs provide higher spatial resolution, CT can detect more subtle variations in attenuation of X-rays higher contrast resolution. CT exposes the patient to significantly more ionizing radiation than a radiograph.
Spiral multidetector CT uses 16, 64, or more detectors during continuous motion of the patient through the radiation beam to obtain fine detail images in a short exam time.
With rapid administration of intravenous contrast during the CT scan, these fine detail images can be reconstructed into three-dimensional 3D images of carotid, cerebral, coronary or other arteries. The introduction of computed tomography in the early s revolutionized diagnostic radiology by providing Clinicians with images of real three-dimensional anatomic structures.
CT scanning has become the test of choice in diagnosing some urgent and emergent conditions, such as cerebral hemorrhage, pulmonary embolism clots in the radiology residency personal statement of the lungsradiology residency personal statement, aortic dissection tearing of the aortic wallappendicitisdiverticulitisand obstructing kidney stones. Continuing improvements in CT technology, including faster scanning times and improved resolution, have dramatically increased the accuracy and usefulness of CT scanning, radiology residency personal statement, which may partially account for increased use in medical diagnosis.
Medical ultrasonography uses ultrasound high-frequency sound waves to visualize soft tissue structures in the body in real time. No ionizing radiation is involved, but the quality of the images obtained using ultrasound is highly dependent on the skill of the person ultrasonographer performing the exam and the patient's body size.
Examinations of larger, overweight patients may have a radiology residency personal statement in image quality as their subcutaneous fat absorbs more of the sound waves. This results in fewer sound waves penetrating to organs and reflecting back to the transducer, resulting in loss of information and a poorer quality image.
Ultrasound is also limited by its inability to image through air pockets lungs, bowel loops radiology residency personal statement bone. Its use in medical imaging has developed mostly within the last 30 years. The radiology residency personal statement ultrasound images were static and two-dimensional 2Dbut with modern ultrasonography, 3D reconstructions can be observed in real time, effectively becoming "4D".
Because ultrasound imaging techniques do not employ ionizing radiation to generate images unlike radiography, and CT scansthey are generally considered safer and are therefore more common in obstetrical imaging.
The progression of pregnancies can be thoroughly evaluated with less concern about damage from the techniques employed, allowing early detection and diagnosis of many fetal anomalies. Growth can be assessed over time, important in patients with chronic disease or pregnancy-induced disease, and in multiple pregnancies twins, triplets, etc. Color-flow Doppler ultrasound measures the severity of peripheral vascular disease and is used by cardiologists for dynamic evaluation of the heart, heart valves and major vessels.
Stenosisfor example, of the carotid arteries may be a warning sign for an impending stroke. A clotembedded deep in one of the inner veins of the legs, can be found via ultrasound before it dislodges and travels to the lungs, resulting in a potentially fatal pulmonary embolism, radiology residency personal statement.
Ultrasound is useful as a guide to performing biopsies to minimize damage to surrounding tissues and in drainages such as thoracentesis. Small, portable ultrasound devices now replace peritoneal lavage in trauma wards by non-invasively assessing for the presence of internal bleeding and any internal organ damage.
Extensive internal bleeding or injury to the major organs may require surgery and repair. MRI uses strong magnetic fields to align atomic nuclei usually hydrogen protons within body tissues, then uses a radio signal to disturb the axis of rotation of these nuclei and observes the radio frequency signal generated as the nuclei return to their baseline states. An advantage of MRI is its ability to produce images in axialcoronalsagittal and multiple oblique planes with equal ease.
Radiology residency personal statement 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 become an important tool in musculoskeletal radiology and neuroradiology.
One disadvantage is the patient has to hold still for long periods of time in a noisy, cramped space while the imaging is performed. Recent improvements in magnet design including stronger magnetic fields radiology residency personal statement teslasshortening exam times, wider, shorter magnet bores and more open magnet designs, have brought some relief for claustrophobic patients.
However, for magnets with equivalent field strengths, there is often a trade-off between image quality and open design, radiology residency personal statement. MRI has great benefit in imaging the brain, spine, and musculoskeletal system.
The use of MRI is currently contraindicated for patients with pacemakers, cochlear implants, some indwelling medication pumps, certain types of cerebral aneurysm clips, metal fragments in the eyes and some metallic hardware due to the powerful magnetic fields and strong fluctuating radiology residency personal statement signals to which the body is exposed.
Areas of potential advancement include functional imaging, cardiovascular MRI, and MRI-guided therapy. Nuclear medicine imaging involves the administration into the patient of radiopharmaceuticals consisting of substances with affinity for certain body tissues labeled with radioactive tracer. The most commonly used tracers are technetiumm, iodine, iodine, radiology residency personal statement, gallium, indium, thallium and fludeoxyglucose 18 F 18 F-FDG. The heartlungsthyroidliverbraingallbladderand 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. The excretory function of the kidneys, iodine-concentrating ability of the thyroid, blood flow to heart muscle, etc. can be measured. The principal imaging devices are the gamma camera and the PET Scanner, which detect the radiation emitted by the tracer in the body and display it as an image.
With computer processing, the information radiology residency personal statement be displayed as axial, coronal and sagittal images single-photon emission computed tomography - SPECT or Positron-emission tomography - PET. In the most modern devices, nuclear medicine images can be fused with a CT scan taken quasisimultaneously, so the physiological information can be overlaid or coregistered with the anatomical structures to improve diagnostic accuracy.
Positron emission tomography PET scanning deals with positrons instead of gamma rays detected by gamma cameras. The positrons annihilate to produce two opposite traveling gamma rays to be detected coincidentally, thus improving resolution. In PET scanning, a radioactive, biologically active substance, most often 18 F-FDG, is injected into a patient and the radiation emitted by the patient is detected to produce multiplanar images of the body. Metabolically more active tissues, such as cancer, concentrate the active substance more than normal tissues.
PET images can be combined or "fused" with anatomic CT imaging, to more accurately localize PET findings and thereby improve diagnostic accuracy. The fusion technology has gone further to combine PET and MRI similar to PET and CT. The technology recently blossomed after passing the technical hurdle of altered positron movement in strong magnetic field thus affecting the resolution of PET images and attenuation correction.
Interventional radiology 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.
The basic concept behind interventional radiology is to diagnose or treat pathologieswith the most minimally invasive technique possible. Minimally invasive procedures are currently performed more than ever before. These procedures are often performed with the patient fully awake, with little or no sedation required, radiology residency personal statement. Interventional radiologists and interventional radiographers [9] diagnose and treat several disorders, including peripheral vascular diseaserenal artery stenosisradiology residency personal statement vena cava filter placement, gastrostomy tube placements, biliary stents and hepatic interventions.
Radiographic images, fluoroscopy, and ultrasound modalities are used radiology residency personal statement guidance, radiology residency personal statement, and the primary instruments used during the procedure are specialized needles and catheters.
The images provide maps that allow the clinician to guide these instruments through the body to the areas containing disease. By minimizing the physical trauma to the patient, peripheral interventions can reduce infection rates and recovery times, as well as hospital stays.
To be a trained interventionalist in the United States, an individual completes a five-year residency in radiology and a one- or two-year fellowship in IR, radiology residency personal statement.
The basic technique is optical density evaluation i. histogram analysis. It is then described that a region has a different optical density, e. a cancer metastasis to bone can cause radiolucency. The development of this is the digital radiological subtraction. It consists in overlapping two radiographs of the same examined region and subtracting the optical densities [1], radiology residency personal statement. The resultant image only contains the time-dependent differences between the two examined radiographs.
The advantage of this technique is the precise determination of the dynamics of density changes and the place of their occurrence. However, beforehand the geometrical adjustment and general alignment of optical density should be done [2].
Another possibility of radiographic image analysis is to study second order features, e.
