	Nuclear Medicine, PET
		PET scans are used most often to detect cancer and to examine the effects of cancer therapy by characterizing biochemical changes in the cancer.
		PET scans of the heart can also be used to determine if areas of the heart that show decreased function are alive rather than scarred as a result of a prior heart attack, called a myocardial infarction.
		PET scans of the brain are used to evaluate patients who have memory disorders of an undetermined cause, suspected or proven brain tumors or seizure disorders that are not responsive to medical therapy and are therefore candidates for surgery.

	Anna Jaques Hospital - Find a Service - PET Scan
		During a PET scan, a radioactive substance called a tracer is combined with a chemical (such as glucose); this mixture is generally injected into a vein (usually in the arm) but on occasion may be inhaled.
		A PET scan is often used to detect and evaluate cancer, such as of the lung or breast.
		For example, if a PET scan shows that blood flow is reduced to a large area of the heart, but the heart's metabolism is unaffected (which means the heart tissue is not dead), a person may be a candidate for coronary artery bypass surgery.

	Positron Emission Tomography (PET) (Site not responding. Last check: 2007-09-17)
		Since PET is a type of nuclear medicine procedure, this means that a tiny amount of a radioactive substance, called a radiopharmaceutical (radionuclide or radioactive tracer), is used during the procedure to assist in the examination of the tissue under study.
		PET is most often used by oncologists (physicians specializing in cancer treatment), neurologists and neurosurgeons (physicians specializing in treatment and surgery of the brain and nervous system), and cardiologists (physicians specializing in the treatment of the heart).
		PET works by using a scanning device (a machine with a large hole at its center) to detect positrons (subatomic particles) emitted by a radionuclide in the organ or tissue being examined.

		PET has been shown to be an accurate method to diagnose and stage cancer, check for tumor recurrence and monitor cancer therapy.
		PET scanning is commonly used to diagnose and manage brain diseases such as epilepsy and Alzheimer's disease.

	Untitled Document
		PET is a nuclear medicine technique using a camera, which captures images of the human body's function.
		The PET scanner detects and records photons that arrive at the scanner's detectors simultaneously and moving in opposite directions.
		The resolution of a PET scanner is therefore approximately 2 microns.

	Positron emission tomography - Wikipedia, the free encyclopedia
		PET scans are increasingly read alongside CT scans or MRI scans, the combination ("co-registration") giving both anatomic and metabolic information (i.e., what the structure is, and what it is doing biochemically).
		The PET scanner does this via the use of radiolabelled molecular probes that have different rates of uptake, depending on the type and function of tissue involved.
		Neurology: PET neuroimaging is based on an assumption that areas of high radioactivity are associated with brain activity.

		The first Allegro whole-body PET scanner was installed at the University of Pennsylvania PET center in Fall 2001, in the Department of Radiology, and is currently being used for clinical imaging.
		The scanner was developed at the University of Pennsylvania, in collaboration with ADAC UGM in Philadelphia.
		Very high spatial resolution in PET is needed for small animal studies for two reasons; to clearly identify small structures of the activity distribution, and to enhance the contrast of tissue with higher concentration of activity from the surrounding areas.

	PET Scan
		PET is a nuclear medicine technique using a camera, which captures powerful images of the human body's function and reveals information of health and disease.
		PET detects chemical and metabolic changes in disease states, such as cancer, before anatomic and structural changes (detected by conventional imaging) have time to develop.
		PET evaluation of tissue metabolism can indicate the probable presence or absence of malignancy based on differences of biological activity, where as anatomic imaging depends on size and radiographic characteristics of lesions to determine the likelihood of malignancy.

		Detectors in the PET scanner record the relative position of the pairs of photons, identifying and locating millions of positron-electron collisions per second.
		PET scanning is particularly effective, for example, in diagnosing cancers, as it can follow the course of the cancer through the body and accurately show the extent of the disease.
		Another area of PET application that continues to develop is in the diagnosis of common neurological disorders, such as Alzheimer's disease, Hodgkins disease, and stroke.

	Permanent PET/CT Scanner and High Field Open MRI Scanner
		PET is at the cutting edge of diagnosis for many initial tumors, too, but not for tiny ones such as many breast tumors less than 1 – 2 centimeters in size.
		For general oncology, the PET scan is typically a full-body image, from the skull base to the pelvis.
		Open scanners have a particular advantage over closed equipment for musculoskeletal scans, explains Dr. Ma, “because we can place the body part exactly in the middle, not the edge, of the magnetic field.” An image of an elbow or a wrist, for example, can be better on an open high field MRI scanner.

	PET/CT Scanner
		The PET/CT systems now in wide clinical use combine a multidetector PET system with a multidetector (currently 4-16 slice) computed tomography (CT) scanner in a single unit with a patient couch which traverses the bore of both imaging components.
		Most importantly, acquiring the CT and PET data in very close temporal proximity with the patient in the same position on the imaging couch minimizes patient motion between the two acquisitions which allows more precise anatomic localization of FGD activity.
		The CT and PET data sets are fused or “coregistered” electronically by the scanner’s computer system and presented to the interpreter on a work station.
