Cerebral blood flow measurement

The determination of cerebral blood flow provides objective indicators for studying the functional indicators of human brain under different pathological and physiological conditions, and is also helpful for studying the pharmacological effects of cerebral circulation drugs. The patient inhales a certain radioisotope, and the instrument device has a multi-probe function measuring device belt and a camera attached to the computer. The cerebral blood flow was measured. Try to find a relative and friend to accompany you. Oral potassium perchlorate 400mg should be taken 30-60 minutes before the injection of the imaging agent to block the choroid plexus and the thyroid gland to reduce interference. Basic Information Specialist Category: Cardiovascular Examination Category: Other Examinations Applicable gender: whether men and women apply fasting: not fasting Tips: 1 or 2 days before the examination, try to stop the expansion of cerebrovascular drugs to increase the sensitivity of the examination. Normal value The whole brain blood flow of healthy adults is 700-1000 ml/min. Clinical significance Abnormal results: The whole brain blood flow is greater than or less than 700 ~ 1000ml / min, indicating that the cerebral vascular obstruction or certain brain diseases. Need to check the population with cerebral infarction, cerebral hemorrhage, aneurysm, congenital arteriovenous and other brain diseases. High results may be diseases: adult ADHD, cerebral ischemic disease precautions Forbidden before examination: 1 or 2 days before the examination, try to stop the expansion of the cerebral vasculature to increase the sensitivity of the examination. Requirements for inspection: Try to find a relative and friend to accompany you. Oral potassium perchlorate 400mg should be taken 30-60 minutes before the injection of the imaging agent to block the choroid plexus and the thyroid gland to reduce interference. 5-10 minutes before and after the injection, the patient should rest as much as possible to reduce the sound and light stimulation. Inspection process The patient inhales a certain radioisotope, and the instrument device has a multi-probe function measuring device belt and a camera attached to the computer. The cerebral blood flow was measured. Not suitable for the crowd Inappropriate crowd: No.
