    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.

    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 x-ray 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 for...

    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 x-ray is an imaging test to look at cervical vertebrae. These are the seven bones of the spine in the neck. This test is done in a hospital radiology ...

    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 x-ray is a picture of the bones around both the hips. The pelvis connects the legs to the body. The test is done in a radiology department or in the...

    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 x-ray examination of the bladder in which contrast dye is placed into the bladder through the urethra. The urethra is th...

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

    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.
