an examination

Eyeball protrusion, orbital trauma, foreign body localization

Vertical diameter

35 ~ 40mm

Test solution

40% lipiodol or 60% diatrizoate 1-2ml

The X-ray of the eye routinely uses the X-ray fluorescence effect to place the patient between the bulb and the fluorescent screen, and the observation is called perspective.

Check and confirm

Often referred to as a plain scan or non-enhanced scan, it refers to a scan without intravenous injection of contrast agent or contrast. Normally, the scan is performed first. Ordinary scans of the abdomen and pelvic cavity usually take a certain amount of contrast agent to fill the gastrointestinal tract before the scan to increase the contrast between the internal organs such as the gastrointestinal cavity and the surrounding tissues.

Eye X-ray and CT enhanced scan

It is a method of injecting a water-soluble organic iodine contrast agent into a vein before scanning. The injection method can be drip, bolus, or a combination of both. Enhanced scanning is mainly used to: find lesions not shown on plain scan; identify edema and diseased tissue; further clarify the size of the lesion and its relationship with surrounding tissues to provide information for the treatment plan; and provide further differential diagnosis information for difficult cases.

Eye X-ray and CT scan

Is the method of organ or tissue imaging, and then scan. For example, inject 8 to 10 ml of iodotrexam into the cistern or inject 4 to 6 ml of air into the cerebellar angiography and then scan, which is called a cerebellar angiography CT examination.
