Part Description

LP70654-6   Cerebral atrophic index
The cerebral atrophic index (CAI or ATI) is the ratio of cerebrospinal fluid or infarcted brain to intracranial volume. CAI has been correlated with cognitive impairments in conditions such as alzheimers disease and ischemic vascular dementia (IVD). PMID: 7740559 Source: Regenstrief LOINC, PMID:7740559
