Simple chest x-rays may reveal collapse due to airway obstruction. The contralateral lung may be hyperinflated. Casts can be visualized within the major airways using computerized axial tomography scans. Heavy T2-weighted MRI, and, as appropriate, intranodal lymphangiogram and/or dynamic contrast-enhanced MR lymphangiography may be useful for identifying pathological lymphatic tissue or lymphatic flow.

Cloacal exstrophy (EC) is a severe birth defect wherein much of the abdominal organs (the bladder and intestines) are exposed. It often causes the splitting of the bladder, genitalia, and the anus. It is sometimes called OEIS complex. Diagnostic tests can include ultrasound, voiding Cystourethrogram (VCUG),MRI, intravenous Pyelogram (IVP), nuclear renogram, computerized axial tomography (CAT Scan), and magnetic resonance imaging (MRI).

Biomedical Optics is the field of performing noninvasive operations and procedures to patients. This has been a growing field, as it is easier and does not require the patient to be opened. Biomedical Optics is made possible through imaging such as CAT (computerized axial tomography) scans. One example of biomedical optics is LASIK eye surgery, which is a laser microsurgery done on the eyes.

Albert Macovski is an American Professor (Emeritus) at Stanford University, known for his many innovations in the area of imaging, particularly in the medical field. He has over 150 patents and has authored over 200 technical articles. His innovations include the single-tube color camera and real-time phased array imaging for ultrasound. He has also made significant contributions to magnetic resonance imaging (MRI), computerized axial tomography (CAT scans), and digital radiography.

This technique was called pneumoencephalography. In 1927, Egas Moniz introduced cerebral angiography, whereby both normal and abnormal blood vessels in and around the brain could be visualized with great precision. In the early 1970s, Allan McLeod Cormack and Godfrey Newbold Hounsfield introduced computerized axial tomography (CAT or CT scanning), and ever more detailed anatomic images of the brain became available for diagnostic and research purposes. Cormack and Hounsfield won the 1979 Nobel Prize for Physiology or Medicine for their work.

A patient experiencing symptoms of hypoesthesia is often asked a series of questions to pinpoint the location and severity of the sensory disruption. A physical examination may follow where a doctor may tap lightly on the skin to determine how much feeling is present. Depending upon the location of the symptoms occurring, a doctor may recommend some tests to determine the overlying cause of the hypoesthesia. These tests include imaging computerized axial tomography (CT) and magnetic resonance imaging (MRI) scans, nerve conduction studies to measure electrical impulses passing through the nerves in search of damage to the nerves, and various reflex tests.

The individual in question, has all his teeth very well preserved, without any wear and tear, has "caucusian features" (brown red hair) and his hands that do not reveal that he had done hard physical work. On the part of the Computerized axial tomography (CT) that was made to this mummy revealed that the viscera were not removed to mummify it and that in fact, it conserves the brain, which contradicts some historical Castilian chronicles that tell how was the mummification process between the Guanches. The mummy was found in Barranco de Herques, in the south of Tenerife, between the towns of Fasnia and Güímar. He arrived in Madrid in the eighteenth century as a gift to King Charles III of Spain.

Medical devices are defined by the US Food and Drug Administration (FDA) as any object or component used in diagnosis, treatment, prevention, or cure of medical conditions or diseases, or affects body structure or function through means other than chemical or metabolic reaction in humans or animals. This includes all medical tools, excluding drugs, ranging from tongue depressors to Computerized Axial Tomography (CAT) scanners to radiology treatments. Because of the wide variety of equipment classified as medical devices, the FDA has no single standard to which a specific device must be manufactured; instead they have created an encompassing guide that all manufacturers must follow. Manufacturers are required to develop comprehensive procedures within the FDA framework in order to produce a specific device to approved safety standards.

Projects at the Jet Propulsion Laboratory, MIT, Bell Labs and the University of Maryland, among others, used digital images to advance satellite imagery, wirephoto standards conversion, medical imaging, videophone technology, character recognition, and photo enhancement.Azriel Rosenfeld, Picture Processing by Computer, New York: Academic Press, 1969 Rapid advances in digital imaging began with the introduction of MOS integrated circuits in the 1960s and microprocessors in the early 1970s, alongside progress in related computer memory storage, display technologies, and data compression algorithms. The invention of computerized axial tomography (CAT scanning), using x-rays to produce a digital image of a "slice" through a three- dimensional object, was of great importance to medical diagnostics. As well as origination of digital images, digitization of analog images allowed the enhancement and restoration of archaeological artifacts and began to be used in fields as diverse as nuclear medicine, astronomy, law enforcement, defence and industry.

Stark Law is a set of United States federal laws that prohibit physician self- referral, specifically a referral by a physician of a Medicare or Medicaid patient to an entity for the provision of designated health services ("DHS") if the physician (or an immediate family member) has a financial relationship with that entity. The term "referral" means "the request by a physician for the item or service" for Medicare Part B services and "the request or establishment of a plan of care by a physician which includes the provision of the designated health service" for all other services. DHS includes "clinical laboratory services"; "physical therapy services"; "occupational therapy services"; "radiology services, including magnetic resonance imaging, computerized axial tomography scans, and ultrasound services"; "radiation therapy services and supplies"; "durable medical equipment and supplies"; "parenteral and enteral nutrients, equipment, and supplies"; "prosthetics, orthotics, and prosthetic devices and supplies"; "home health services"; "outpatient prescription drugs"; "inpatient and outpatient hospital services"; and "outpatient speech-language pathology services." A "financial relationship" includes ownership, investment interest, and compensation arrangements.
