Skull plain film

The skull is a photograph of the skull used to see if the skull has abnormal lesions. Localized changes in the cranial wall, brain tumors close to the cranial wall can compress or erode the cranial wall and cause localized bone destruction or bone hyperplasia. More common in the skull bone. The location of the brain tumor can be determined based on the location of the bone change. This change is more common in meningiomas. Basic Information Specialist classification: growth and development check classification: X-ray Applicable gender: whether men and women apply fasting: not fasting Reminder: X-ray examination is required for treatment diagnosis, and lead protection products should be worn. Normal value The photo did not find unusual shadows and areas. Clinical significance Abnormal results: The following positioning signs can appear on the flat film: 1 Localized changes in the cranial wall, brain tumors close to the cranial wall can compress or erode the cranial wall and cause localized bone destruction or bone hyperplasia. More common in the skull bone. The location of the brain tumor can be determined based on the location of the bone change. This change is more common in meningiomas. 2 Sella changes, pituitary tumors in the saddle, can make the saddle balloon increase, the saddle back can also move back and vertical, there is a "saddle type" change, can be diagnosed as a saddle tumor. The tumor above the sella can make the saddle back short, the flattened saddle and the opening increase, and a "saddle-up" change occurs. The parasagittal tumor can cause double images on the same side of the saddle, even on the saddle back. The saddle enlarges and the ipsilateral anterior bed is upturned or destroyed, and a "saddle-side" change occurs. 3 Rock bone and inner ear canal changes, close to the rock bone tip and the inner ear canal tumor, such as acoustic neuroma can enlarge the inner ear canal, rock bone destruction, bone defects can be formed in the late stage. 4 Calcium spots, brain tumors are more prone to calcium spots, the development rate is 3% to 15%. According to calcium spots, the location of brain tumors can be roughly determined. Note that the location and morphology of the calcium spot can also be estimated. For example, the arc-shaped or irregular-shaped calcium spots in the sellar region are mostly craniopharyngioma; the mass-like calcium spots in the meningioma are mostly oligodendrogliomas. 5 pineal body calcium spot shift, according to the pineal gland displacement direction can be roughly estimated brain tumor location. One side of the cerebral hemisphere tumor causes it to shift to the opposite side. The tumor in the frontal region is displaced backwards and downwards, and the tumor in the top region is displaced downward. The above signs can be combined. For example, meningioma can have signs of localized bone hyperplasia, massive calcium spots, and increased intracranial pressure of pineal gland. People who need to be examined: people with frequent head dizziness, headaches, and abnormal pain. Precautions Taboo before inspection: X-rays have certain radiation and need to be mentally prepared. X-ray examination is required for treatment diagnosis, and lead protection products should be worn. Protect the non-illuminated parts, especially the areas sensitive to X-ray reactions such as gonads and thyroids, and wear protective equipment. Requirements for inspection: Obey the doctor's instructions to check. When the X-ray machine is in working condition, the warning indicator on the radiation chamber door will be on. At this time, the patient will wait outside the protective door and do not wait for the film in the inspection room. If the patient does not need special care, the family should not enter the examination room to accompany them to reduce unnecessary radiation. Inspection process Preparation before photography: No special preparation is required for the skull, chest, limbs and other parts. When photographing the abdomen, lower spine, pelvis, and urinary tract, the contents of the intestine must be removed, otherwise the diagnosis will be affected. Photography steps: Carefully check the patient's name, gender, age, and location. Select the appropriate size of the cassette according to the inspection site. Place the number, date, and left and right markers. The choice of grids, where the thickness is generally more than 12 cm, requires a grid. Remove clothing or substances that affect X-ray penetration, such as hairpins, ornaments, ointments, and dressings (as appropriate). Select the appropriate exposure conditions, focus size, kilovolts, milliamps, time, focus - slice distance. The part of the photography related to breathing (such as the chest and abdomen) should be trained to exhale, inhale, and hold your breath. Position the position, measure the center line, and start the machine exposure. Recording conditions are recorded after the photography is completed. Not suitable for the crowd Pregnant women, teenagers. Adverse reactions and risks No complications.
