This page has the list of all fields in the CHAVI database.


CHAVI hosts a wealth of clinical data related to the patients from whom the images have been obtained. This data is available in a relational database which allows you to construct complex queries to search the image data. Thus not only can you access this data of the dataset as a whole but you can also access data across different projects. The database architecture is described in the database page. This page has the list of all available database fields for which clinical data may be available. Please note that data in all fields may not be available for all patients.
