The doctor will perform a physical exam. The doctor may see signs of dementia and abnormal movements. Reflexes may be abnormal. The gait is often "prancing" and wide. Speech may be hesitant or enunciation poor. A head CT scan may show loss of brai...

A cranial CT scan is computed tomography of the head, including the skull, brain, orbits (eye sockets), and sinuses.
|
 |
Computed tomography (CT) scans are completed with the use of a 360-degree x-ray beam and computer production of images. These scans allow for cross- sectional views of body organs and tissues.

Injury to the head may damage the scalp, skull , or brain . The most important consequence of head injury is traumatic brain injury.

CT imaging equipment includes conventional, spiral, multi-slice, and electron-beam computed tomography full-body scanners, which use x rays to acquire cross-sectional images and computer workstations to reconstruct acquired image data for display on a viewing monitor or printed on film. Also referred to as computerized axial tomography (CAT) scanning equipment.

Computed tomography (also known as CT, CT scan, CAT, or computerized axial tomography) scans use x rays to produce precise cross-sectional images of anatomical structures. With the development of modern computers, the scans enhanced digital capabilities allowed the development of computed tomography imaging (derived from the Greek tomos , meaning " to slice " ).

Certain inherited genetic conditions increase the risk of cardiovascular disease, so having a genetic test may show whether a person is at risk for heart disease, especially if a family member has one of the conditions.

During a physical examination, a health care provider studies a patient's body to determine the presence or absence of physical problems. A typical physical examination includes: Inspection (looking at the body; Palpation (feeling the body with hands; Auscultation (listening to sounds; Percussion (producing sounds.

An MRI of the head is a noninvasive procedure that uses powerful magnets and radio waves to construct clear, detailed pictures of brain tissues. Conventional radiography and computed tomographic (CT) imaging use potentially harmful radiation (x-rays) that passes through a patient to generate images. Magnetic resonance imaging (MRI) is based on the magnetic properties of atoms, and there is no exposure to the same type of radiation used in x-rays and CT scans. A powerful magnet generates a magnetic field roughly 10,000 times stronger than the Earth's. A very small percentage of hydrogen atoms within the body will align with this field. Radio wave pulses are broadcast towards the aligned hydrogen atoms in tissues of interest, returning a signal of their own. The slight differences of those signals from different tissues enables MRI to tell the difference between various organs, and potentially, provide contrast between benign and malignant tissue. Any imaging angle, or "slice", can be projected, and then stored in a computer or printed on film. MRI can easily be performed through clothing and bones. However, certain types of metal in or around the area of interest can cause significant errors in the reconstructed images. These errors are called artifacts.

Positron emission tomography (PET) is an imaging test that uses a radioactive substance (called a tracer) to look for disease in the body. Unlike magnetic resonance imaging (MRI) and computed tomography (CT) scans, which reveal the structure of organs, a PET scan shows how the organs and tissues are functioning. See also: Bone scan; Lung scan; Nuclear ventriculography; Pulmonary ventilation/perfusion scan; Renal scan; Thyroid scan.

|
Positron emission tomography (PET) is a noninvasive scanning technique that utilizes small amounts of radioactive positrons (positively charged particles) to visualize body function and metabolism. PET is the fastest growing nuclear medicine tool in terms of increasing acceptance and applications.

PET Scan Use in Cancer Diagnosis and Treatment MonitoringFinding cancer at its earliest stage can give the best chance of being able to cure it. Different tests are used to find cancers and to help find out if the cancer has spread.

Positron emission tomography (PET) is a scanning technique used in conjunction with small amounts of radiolabeled compounds to visualize brain anatomy and function. A PET scan showing brain activity while patient recognizes faces- left sides at left/right sides at right.

 |
Positron emission tomography (PET) is a highly specialized imaging technique using short-lived radiolabeled substances to produce powerful images of the body ' s biological function. Purpose Besides being used to investigate the metabolism of normal organs, PET has also become the technique of choice to investigate various neurological diseases and disorders, including stroke, epilepsy, Alzheimer ' s disease, Parkinson ' s disease, and Huntington ' s disease.
|
|
Rather than showing the structure of a body part, PET images show the chemical function of an organ or tissue. PET can show changes in how an organ or tissue works. This can help your healthcare provider diagnose problems and develop a treatment plan for you.

Positron emission tomography (PET) is a highly specialized imaging technique using short-lived radiolabeled substances to produce extremely high resolution images of the body ' s biological function. Purpose Besides being used to investigate the metabolism of normal organs, PET has also become the technique of choice to investigate various neurological diseases, including stroke , epilepsy, Alzheimer ' s disease , Parkinson ' s disease, and Huntington ' s disease.
