Sella lateral view

The lateral position of the sella is a lateral filming of the sella to check whether the sella has a tumor lesion. The size of the saddle varies from person to person. The front and rear diameters of the saddle are 8 to 16 mm, with an average of 11.5 mm and a depth of 7 to 14 mm, with an average of 9.5 mm. The people who need to be examined have people with pituitary gland endocrine disorders, vision loss, visual field defects, and blindness. Basic Information Specialist classification: Oncology examination classification: X-ray Applicable gender: whether men and women apply fasting: not fasting Tips: Lead protective equipment 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. Normal value The size of the saddle varies from person to person. The front and rear diameters of the saddle are 8 to 16 mm, with an average of 11.5 mm and a depth of 7 to 14 mm, with an average of 9.5 mm. Clinical significance Abnormal results: In the case of senile bone atrophy, the contour of the sella is less pronounced due to sparse bone. The tumor in the saddle causes the compression of the parietal bone wall to expand it in a spherical shape. In severe cases, the bone structure can be absorbed and destroyed. Para-saddle tumors often shorten the erosion of one side of the saddle, the shape of the saddle is butterfly-shaped, the upper mouth is wider, the anteroposterior diameter is increased, and the bone can be absorbed and destroyed. People who need to be examined: people with pituitary gland endocrine disorders, vision loss, visual field defects, blindness, etc. 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, etc. 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 Inappropriate crowd: pregnant women, teenagers. Adverse reactions and risks Nothing.
