Provocative discography is an imaging-guided procedure in which a contrast agent is injected into the nucleus pulposus of the intervertebral disc. It provides both anatomical and functional information about a disc suspected to be diseased. Following intradiscal contrast injection, disc morphology is usually assessed on radiographs or computed tomography (CT), or both. The functional evaluation consists of pain provocation and careful assessment of the patient's response to pain. The discography results influence the surgical decision-making process and selection of disc levels to be operated on.

It is the most widely used psychometric test for measuring adult psychopathology in the world. The MMPI-2 is used in mental health, medical and employment settings. The test developers Hathaway and McKinley used an empirical test construction technique to develop the MMPI. This involved basing the test scales (for example the hypochondriasis scale) on the actual test items that differentiate people with hypochondriasis from 'normals.' Often, the questions that do this most reliably are not concerned with health issues as such. This has two advantages. First, it makes it very difficult for subjects to 'fake' responses, deny problems or give a particular impression. Second, the MMPI-2 is based on empirical research and not on a clinician's assumptions about what answers indicate particular personality traits. elibrary.judiciary.gov.ph/thebookshelf/showdocsfriendly/1/61305 21/25
