    Bone x-ray

    The skeleton consists of groups of bones which protect and move the body.

    Chest x-ray

    This chest x-ray shows adenocarcinoma of the lung. There is a rounded light spot in the right upper lung (left side of the picture) at the level of the second rib. The light spot has irregular and poorly defined borders and is not uniform in density. Diseases that may cause this type of x-ray result would be tuberculous or fungal granuloma, and malignant or benign tumors.

    A chest x-ray is an of the chest, lungs, heart, large arteries, ribs, and diaphragm.

    Dental x-rays

    The structure of the tooth includes dentin, pulp and other tissues, blood vessels and nerves imbedded in the bony jaw. Above the gum line, the tooth is protected by the hard enamel covering.

    Dental x-rays are a type of picture of the teeth and mouth. X-rays are a form of electromagnetic radiation, just like visible light. They are of higher energy, however, and can penetrate the body to form an image on film. Structures that are dense (such as silver fillings or metal restoration) will ...

    Extremity 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.

    An extremity is an image of the hands, wrist, feet, or all of these areas. The term “extremity” often refers to a human hand or foot. X-rays are a form of radiation that pass through the body to form an image on film. Structures that are dense (such as bone) will appear white. Air will ...

    Hand x-ray

    A hand is a medical image of one or both hands.

    Intravenous pyelogram

    The kidneys are responsible for removing wastes from the body, regulating electrolyte balance and blood pressure, and stimulating red blood cell production.

    An intravenous pyelogram (IVP) is a special examination of the kidneys, bladder, and ureters (the tubes that carry urine from the kidneys to the bladder).

    Joint x-ray

    This test is an of a knee, shoulder, hip, wrist, ankle, or other joint.

  • Test

    Neck x-ray

    These are the seven bones of the neck, called the cervical vertebra.  The top bone, seen on the right of this picture, is called the atlas, and is where the head attaches to the neck.  The second bone is called the axis, upon which the head and atlas rotate.  The vertebra are numbered from one to seven from the atlas down, and are referred to as C1, C2, C3, etc.

    A neck is an imaging test to look at cervical vertebrae, the seven bones in the neck area.

  • Test

    Pelvis x-ray

    The sacrum is a shield-shaped bony structure that is located at the base of the lumbar vertebrae and that is connected to the pelvis. The sacrum forms the posterior pelvic wall and strengthens and stabilizes the pelvis. Joined at the very end of the sacrum are two to four tiny, partially fused vertebrae known as the coccyx or "tail bone". The coccyx provides slight support for the pelvic organs but actually is a bone of little use.

    A pelvis is a picture of the bones surrounding the hip area. The pelvis connects the legs to the body.

    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 tube that carries urine from the bladder to the outside of the body.

    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.

  • Test

    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.

  • Test

    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 that cushion them.

    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.

  • 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-rays are a type of electromagnetic radiation, just like visible light. An x-ray machine sends individual x-ray particles through the body. The images are recorded on a computer or film. Structures that are dense (such as bone) will block most of the x-ray particles, and will appear white. Metal ...

    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.
