Bone Scan Introduction
Bone Scan Introduction Mohamed 17,965 Views • 2 years ago

A Bone scan or bone scintigraphy is a nuclear scanning test to find certain abnormalities in bone which are triggering the bone's attempts to heal. It is primarily used to help diagnose a number of conditions relating to bones, including: cancer of the bone or cancers that have spread (metastasized) to the bone, locating some sources of bone inflammation (e.g. bone pain such as lower back pain due to a fracture), the diagnosis of fractures that may not be visible in traditional X-ray images, and the detection of damage to bones due to certain infections and other problems.

Nuclear medicine bone scans are one of a number of methods of bone imaging, all of which are used to visually detect bone abnormalities. Such imaging studies include magnetic resonance imaging (MRI), X-ray computed tomography (CT) and in the case of 'bone scans' nuclear medicine. However, a nuclear bone scan is a functional test, which means it measures an aspect of bone metabolism, which most other imaging techniques cannot. The nuclear bone scan competes with the FDG-PET scan in seeing abnormal metabolism in bones, but it is considerably less expensive.

Nuclear bone scans are not to be confused with the completely different test often termed a "bone density scan," DEXA or DXA, which is a low exposure X-ray test measuring bone density to look for osteoporosis and other diseases where bones lose mass, without any bone re-building activity. The nuclear medicine scan technique is sensitive to areas of unusual bone re-building activity because the radiopharmaceutical is taken up by osteoblast cells which build bone. The technique therefore is sensitive to fractures and bone reaction to infections and bone tumors, including tumor metastases to bones, because all these pathologies trigger bone osteoblast activity. The bone scan is not sensitive to osteoporosis or multiple myeloma in bones, and therefore other techniques must be used to assess bone abnormalities from these diseases.

URBN Dental  How do you brush your teeth properly
URBN Dental How do you brush your teeth properly Daniel Cook 1,251 Views • 2 years ago

URBN Dental is here not only to take care of your tooth decay and prevent gingivitis, but also to give you the best at home dental care instructions as well. Do you find brushing your teeth confusing, or are you unsure whether or not you are brushing correctly? The golden standard when it comes to brushing teeth is brushing twice a day for two minute sessions each. You can break down the mouth into four quadrants: upper right, upper left, lower left, and lower right. By doing this, it will be easier for you to brush for thirty seconds in each area and focus on the correct movement instead of location. It is very important to angle the toothbrush at a forty five degree angle to the tooth and gums while using circular motions to remove food debris and plaque. When it comes to your front teeth, using the brush in a vertical position and combining it with circular motions is effective. Using the dental techniques will ensure healthier teeth that are cavity free and less bleeding gums.

Dental implant surgery.
Dental implant surgery. samer kareem 2,805 Views • 2 years ago

Dental implant surgery is a procedure that replaces tooth roots with metal, screwlike posts and replaces damaged or missing teeth with artificial teeth that look and function much like real ones. Dental implant surgery can offer a welcome alternative to dentures or bridgework that doesn't fit well. How dental implant surgery is performed depends on the type of implant and the condition of your jawbone. Dental implant surgery may involve several procedures. The major benefit of implants is solid support for your new teeth — a process that requires the bone to heal tightly around the implant. Because this healing requires time, the process can take many months.

Meniscus Tear repair
Meniscus Tear repair samer kareem 5,974 Views • 2 years ago

A torn meniscus is one of the most common knee injuries. Any activity that causes you to forcefully twist or rotate your knee, especially when putting your full weight on it, can lead to a torn meniscus. Each of your knees has two menisci — C-shaped pieces of cartilage that act like a cushion between your shinbone and your thighbone. A torn meniscus causes pain, swelling and stiffness. You also might feel a block to knee motion and have trouble extending your knee fully. Conservative treatment — such as rest, ice and medication — is sometimes enough to relieve the pain of a torn meniscus and give the injury time to heal on its own. In other cases, however, a torn meniscus requires surgical repair.
