CT - LEFT KNEE How does CT work? CT uses X-rays to perform its work. These X-rays come from an X-ray tube which is placed inside a square machine called the gantry. The part of your body to be scanned goes inside a hole in this gantry. Why is CT such a good modality? Ordinary X-ray pictures are one-dimensional representations of body parts but CT allows us to section the body to view its inner parts. Thus, the skull X-ray only shows us the outer part, whereas CT shows us the inner parts of the brain. Where is CT useful? All parts of the body can be scanned with CT. For each part, there are specific indications or reasons for scanning. Your referring doctor and the consultant radiologist are the best judges of the usefulness of CT scanning in a specific situation and areas. Are there any dangers of CT scanning? Though X-rays involve radiation, there are no dangers, in practice. In women who are pregnant, however, CT scanning should be done after weighing all the risks. What is the injection that I may receive? Majority of the patients will be injected with a "dye" which enhances the ability of CT scans to pick up abnormalities. This is routine. The dye used is a non-ionic contrast medium, which is much safer than the routine, cheaper, ionic dyes. Are there any complications because of the "dye"? 0.5% of patients may get nausea and redness of the skin. Though severe reactions are known, these are very rare and uncommon.


Why is CT - LEFT KNEE done ?

A CT scan can quickly create more detailed pictures of the knee than standard x-rays. The test may be used to detect:

  • Abscess or infection
  • Broken bone
  • Examine fractures and pattern of fractures
  • The cause of pain or other problems in the knee joint(usually when MRI can't be done)Masses and tumors, including cancer
  • Healing problems or scar tissue following surgery

A CT scan may also be used to guide a surgeon to the right area during a biopsy.

Why is CT - LEFT KNEE ?

A computerized tomography scan (CT or CAT scan) uses computers and rotating X-ray machines to create cross-sectional images of the body. These images provide more detailed information than normal X-ray images. A computed tomography (CT) scan is a type of X-ray that shows cross-sectional images of a specific area on your body. CT Left knee would help doctors diagnose disease or inspect serious injuries such as fractures or dislocations on your right knee. During a CT scan, you lie in a tunnel-like machine while the inside of the machine rotates and takes a series of X-rays from different angles. These pictures are then sent to a computer, where they�re combined to create images of slices or cross-sections of the body. They may also be combined to produce a 3-D image of a particular area of the body.

A Computed Tomography (CT) Scan of :

  • Spine creates a visual model of your cervical spine. The cervical spine is the portion of the spine that runs through the neck. Spine is divided into cervical spine (neck), thoracic spine (middle back) and lumbar spine (lower back).
  • Orbit creates detailed pictures of the eye sockets (orbits), eyes and surrounding bones
  • PNS brings out in-depth images of air-filled spaces within the bones of the face, surrounding the nasal cavity. It usually includes the upper area of the throat
  • Chest creates detailed pictures of airways, lungs or lymph nodes in the chest for abnormalities
  • SI (Sacroiliac Joints) creates visual model of lower back . SI is to blame in 15 to 30 percent of people with chronic lower back pain
  • Abdominal CT helps your doctor see the organs, blood vessels and bones in your abdominal cavity
  • A cardiac CT scan is used to view your heart and blood vessels. During the test, a specialized dye is injected into your bloodstream. The dye is then viewed under a special camera in a hospital or testing facility. A heart CT scan may also be called a coronary CT angiogram if it�s meant to view the arteries that bring blood to your heart. The test may be called a coronary calcium scan if it�s meant to determine whether there�s a build-up of calcium in your heart
  • Lumbar spine CT scan let's your doctor can see a cross-section of your lower back. The lumbar portion of the spine is a common area where back problems occur. The lumbar spine is the lowest portion of your spine. It�s made up of five vertebral bones. Below the lumbar spine is the sacrum and below the sacrum is the coccyx (tailbone). Large blood vessels, nerves, tendons, ligaments, and cartilage are also part of the lumbar spine
  • A shoulder CT scan can help doctors see the bones and soft tissues in the shoulder in order to detect abnormalities
  • Pelvis CT creates cross-sectional pictures of the area between the hip bones. This part of the body is called the pelvic area. Structures inside and near the pelvis include the bladder, prostate and other male reproductive organs, female reproductive organs, lymph nodes and pelvic bones
  • A triphasic, or triple-phase,CT scan is an enhanced CT technique mostly used to evaluate liver lesions. This technique acquires images at 3 different time points or phases, following the administration of a CONTRAST
  • CT of the spine is a diagnostic imaging test used to help diagnose or rule out spinal column damage in injured patients. CT scanning is fast, painless, non-invasive and accurate. In emergency cases, it can reveal internal injuries and bleeding quickly enough to help save lives
  • Spine CT is a diagnostic imaging test used to help diagnose or rule out spinal column damage in injured patients. CT scanning is fast, painless, non-invasive and accurate. In emergency cases, it can reveal internal injuries and bleeding quickly enough to help save lives
  • Mastoid CT is CT of your mastoid bones
  • CT of brain is a diagnostic test which makes use of X-rays to create images of brain. These images are then studied to determine whether any abnormal changes have taken place in the brain or any of its parts
  • A CT scan of the arm is an imaging method that uses x-rays to make cross-sectional pictures of the arm.

A CT scan can be performed with or without CONTRAST dye. This CONTRAST material helps your doctor analyze and identify important vessels and structures, and makes it possible to identify abnormalities that cannot be seen without the dye. CT angiography combines a CT scan with the injection of dye. This technique is able to create pictures of the blood vessels in your belly (abdomen) or pelvis area.
