When it is used When a DEXA (DXA) scan is used. DEXA (DXA) scans are used to measure bone density and assess the risk of bone fractures. They're often used to help diagnose bone-related conditions such as osteoporosis (or the risk of developing it).Total body DEXA scans can also be used to measure body composition (the amount of bone, fat and muscle in the body). DEXA scan also uses a low dose of radiation, which means the risks to health are much lower than standard X-rays. Doctors use the results of DEXA scans to help them decide whether treatment for low bone mineral density is needed.

Overview Adrenal angiography or venography: injecting a contrast dye into veins or arteries, then taking X-rays to check blood flow near the adrenal glands; PET scan (positron emission tomography scan): injecting glucose (sugar) into the veins and using a rotating scanner to look for malignant cells throughout the body, not just where the cancer first started to grow

Medical Dictionary It may be put in a vein (IV) in your arm, or it may be placed into other parts of your body (such as the rectum or a joint) to see those areas better. For some types of CT scans, you drink the dye. The dye makes structures and organs easier to see on the CT pictures. A CT scan can be used to study all parts of your body, such as the chest, belly, pelvis, or an arm or leg. It can take pictures of body organs, such as the liver, pancreas, intestines, kidneys, bladder, adrenal glands, lungs, and heart. It also can study blood vessels, bones, and the spinal cord.

- A bone scan is used to examine the bones for damage caused by cancer or another disease. It is a nuclear medicine test, which means that a very small amount of a radioactive substance is used during the procedure.he scan helps find cancer that started in the bones, as well as cancer that metastasized (spread) to the bone from other parts of the body. Bone scans are also used to monitor how cancer in the bone is responding to treatment.

Pancreas Scan A pancreas scan may be performed to screen for primary or metastatic cancer of the pancreas. A pancreas scan may be used to assess response to therapy for pancreatic cancer and/or to monitor the course of the cancer. There may be other reasons for your doctor to recommend a pancreas scan.

Magnetic Resonance Imaging (MRI Scan) An MRI scan can be used as an extremely accurate method of disease detection throughout the body and is most often used after the other testing fails to provide sufficient information to confirm a patient's diagnosis. In the head, trauma to the brain can be seen as bleeding or swelling.

About This Procedure A CT angiography (CTA) scan is a special kind of CT exam that focuses particularly on the blood vessels, using a contrast material to make them show up clearly in the images. Common uses. CTA is used to examine blood vessels in areas including the brain, neck, chest and abdomen. Conditions that the exam can reveal include aneurysms and narrowing of the arteries. Safety. CT examinations improve health care and are an essential part of diagnosis and treatment planning.

Bone Densitometry (DEXA) DXA is most often performed on the lower spine and hips. In children and some adults, the whole body is sometimes scanned. Peripheral devices that use x-ray or ultrasound are sometimes used to screen for low bone mass.In some communities, a CT scan with special software can also be used to diagnose or monitor low bone mass (QCT).XA is most often performed on the lower spine and hips. In children and some adults, the whole body is sometimes scanned. Peripheral devices that use x-ray or ultrasound are sometimes used to screen for low bone mass.

Top 30 Doctor insights on: What Does An Abnormal T Wave Mean Need the numbers from the scan to tell. Dexa measures bone mineral density. If you are below normal then you may be at risk for fracture. You should discuss this with the person who ordered your test. They are being paid for that. In brief: Bone mineral density. Need the numbers from the scan to tell. Dexa measures bone mineral density.

Who should get a bone density test? The central bone density device is used in hospitals and medical offices, while the smaller peripheral device is available in some drugstores and in screening sites in the community. The DEXA scan involves a much smaller radiation exposure than a standard chest X-ray.

DEXA Scan Assesses Bone Density and Osteoporosis Risk A DEXA scan (dual energy x-ray absorptiometry) is a test that assesses whether you have normal bone density, low bone density (also referred to as osteopenia), or osteoporosis. Typically, a DEXA scan, also referred to as a central DEXA scan, measures your bone density at the hip or spine which is where most osteoporosis-related fractures occur.

- A bone scan is used to examine the bones for damage caused by cancer or another disease. It is a nuclear medicine test, which means that a very small amount of a radioactive substance is used during the procedure.sually the entire body is scanned during this procedure. If the results show bone damage that may be caused by cancer, more tests may be necessary. These tests may include a computed tomography (CT) scan, magnetic resonance imaging (MRI) , or a biopsy.

- If you are at risk for osteoporosis or have experienced a bone fracture, a doctor may recommend a bone mineral density (BMD) test. A dual-energy X-ray absorptiometry (DEXA) scan is the most common BMD test. Similar to an X-ray, this painless test measures your bone density, especially at the hip and spine.

Hybrid turf, underground heaters keep Lambeau tundra just right Associated Press. The fabled tundra of Lambeau Field will be far from frozen when the Green Bay Packers and Minnesota Vikings clash in Saturday's NFC playoff game. Temperatures are expected to be in the teens when the game starts at 7 p.m. Lambeau's underground heating system will keep the turf from freezing. Below the surface, a network of plastic pipes containing antifreeze, covered by a foot of sand, make the field of natural grass and artificial fibers playable.

Bone Densitometry (DEXA) Bone density scanning, also called dual-energy x-ray absorptiometry (DXA) or bone densitometry, is an enhanced form of x-ray technology that is used to measure bone loss.DXA is today's established standard for measuring bone mineral density (BMD).maging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging. DXA is most often performed on the lower spine and hips.

Overview A CT scan has many uses, but is particularly well-suited to quickly examine people who may have internal injuries from car accidents or other types of trauma. A CT scan can be used to visualize nearly all parts of the body and is used to diagnose disease or injury as well as to plan medical, surgical or radiation treatment.
