Cistern Imaging

Radionuclide brain pool imaging (Cisternography) was used to accurately diagnose the location and extent of cerebrospinal fluid leak (Cerebrospinal fluidleak CSFL), to further clarify the cause of CSFL, and to use appropriate treatment to cure. Basic Information Specialist Category: Neurological Classification: Radionuclide Applicable gender: whether men and women apply fasting: not fasting Tips: Pay attention to rest before eating and eat properly. The test was performed 40 minutes after intravenous injection of the tracer. Normal value The radioactivity count and position in the brain pool constantly change with time, and the information is continuously and automatically collected by the imaging instrument at a certain speed (such as 1 s/frame, 1 min/frame, etc.) to obtain a series of images reflecting the above dynamic process. Clinical significance Abnormal results: Brain pool imaging is used for: (1) diagnosis of traffic hydrocephalus; (2) diagnosis and localization of cerebrospinal fluid leakage. The diagnosis of hydrocephalus has no significant difference in the diagnostic value of obstructive hydrocephalus compared with X-ray examination, but the diagnosis of traffic hydrocephalus is superior to X-ray examination, especially in the early stage of the disease, X-ray examination is often negative. And this method has a specific positive sign. People who need to be examined: Patients with traffic hydrocephalus and cerebrospinal fluid leakage can be examined. Precautions Contraindications before examination: Intravenous injection of tracer for 40 minutes after examination. Requirements for inspection: should be at rest and use sedative if necessary. Inspection process The water-soluble imaging agent without stimulation and non-participation was injected into the subarachnoid space, and its dynamic tracking with ECT showed its spatial and metabolic distribution with cerebrospinal fluid, so as to understand the formation, flow and absorption of cerebrospinal fluid. Not suitable for the crowd Inappropriate people: Generally no special preparation is required. Adverse reactions and risks Nothing.
