    Retrograde cystography

    Cystography is a detailed study of the bladder, which uses a dye and X-rays.  A catheter is inserted into the bladder in which the dye flows.  When the bladder is full, the catheter is removed and the X-rays are taken. X-rays are also taken when the bladder is empty.  The test is performed to check for the integrity of the bladder, determine the cause of infections and check for tumors or stones.

    Retrograde cystography is a detailed examination of the bladder in which contrast dye is placed into the bladder through the urethra. The urethra is the...

    Sialogram

    A sialogram is a test which takes an X-ray picture of the salivary ducts and the related glandular structures. Sialography may be performed when a disorder of the salivary ducts and/or glands is suspected.

    A sialogram is an of the salivary ducts and glands. The salivary glands are located on each side of the face. They release saliva into the mouth.

    Sinus x-ray

    The sinuses are hollow cavities within the facial bones.  Sinuses are not fully developed until after age twelve.  When people speak of sinus infections, they are most frequently referring to the maxillary and frontal sinuses.

    A sinus is an imaging test to look at the sinuses. These are the air-filled spaces in the front of the skull.

    Skull x-ray

    X-rays are a form of ionizing radiation that can penetrate the body to form an image on film. Structures that are dense (such as bone) will appear white, air will be black, and other structures will be shades of gray depending on density. X-rays can provide information about obstructions, tumors, and other diseases, especially when coupled with the use of barium and air contrast within the bowel.

    A skull is a picture of the bones surrounding the brain, including the facial bones, the nose, and the sinuses.

    Thoracic spine x-ray

    This is the spine and the sacrum with the cervical (neck), thoracic (mid-back), and lumbar (lower back) vertebra.  Notice how the appearance of the vertebra change as you look down the spine.  The change in shape and size reflect the different functions of the neck, mid-back, and lower back.

    A thoracic spine x-ray is an of the twelve chest (thoracic) bones (vertebrae). The vertebrae are separated by flat pads of cartilage called disks that...

    Upper GI and small bowel series

    An upper GI series is performed to examine the esophagus, stomach, and small intestine. The purpose of the test is to detect abnormalities in those areas.

    An upper GI and small bowel series is a set of taken to examine the esophagus, stomach, and small intestine. is a related test.

    Voiding cystourethrogram

    One method of examining bladder function is by injecting dye that is visible on X-rays through a tube (catheter) to fill the bladder. X-rays are taken while the bladder is full and while the patient is urinating (voiding) to determine if fluid is forced out of the bladder through the urethra (normal) or up through the ureters into the kidney (vesicoureteral reflux). This study is usually done with the patient lying on an X-ray table.

    A voiding cystourethrogram is an study of the bladder and urethra that is done while the bladder is emptying.

    X-ray - skeleton

    X-rays are a form of ionizing radiation that can penetrate the body to form an image on film. Structures that are dense (such as bone) will appear white, air will be black, and other structures will be shades of gray depending on density. X-rays can provide information about obstructions, tumors, and other diseases, especially when coupled with the use of barium and air contrast within the bowel.

    A skeletal is an imaging test used to look at the bones. It is used to detect , tumors, or conditions that cause wearing away (degeneration) of the bone.
