The phrase "a diagnostic injection" is correct and usable in written English.
It can be used in medical or technical contexts to refer to an injection administered for the purpose of diagnosing a condition or issue.
Example: "The doctor recommended a diagnostic injection to help determine the cause of the patient's pain."
Alternatives: "diagnostic shot" or "diagnostic dose".
11 To diagnose the SI joint as the pain generator, three or more positive provocation tests are required, followed by an image-guided diagnostic injection confirming the SI joint as the source of pain; also, an immediate pain reduction of 50% or greater after a local anesthetic injection is required to confirm that the pain is generated from the SI joint.
9 Determining that the SI joint is the pain generator is based on three or more positive provocation tests that indicate that the SI joint is the source of pain, followed by a confirmatory image-guided diagnostic injection of the SI joint; a 50% or greater reduction in pain immediately after the injection of a local anesthetic is used to confirm that the SI joint is the pain generator.
Due to the nature of the reference standard procedure used in this study (intra-articular ACJ diagnostic injection), a valid reference standard outcome required an intact joint capsule to minimise the possibility of anaesthetisation of extra-articular ACJ structures that may produce a false-positive result.
All patients with a positive response to diagnostic injection reported pain with at least one SIJ test.
Following a standardised clinical examination and diagnostic injection into the subacromial bursa, all participants received a fluoroscopically guided diagnostic block of 1% lidocaine hydrochloride (XylocaineTM) into the ACJ.
Based on pain drawings and patient self-report, complete abolition of the patient's primary or dominant pain was designated as reference standard B. Dominant pain location was acquired by pain drawing and direct questioning, and documented prior to clinical examination and diagnostic injection in a prospective manner.
As the outcomes of our study revealed changes in sensory hypersensitivity following a significant decrease in self-reported pain intensity in the cervical spine, one may speculate that our diagnostic injection procedures targeted a primary source of pain.
The diagnostic accuracy estimates for these clinical features were then compared with the estimates for traditional ACJ tests to determine the individual or combinations of clinical features that were most accurate for identifying an 80% PAR following ACJ diagnostic injection.
As a diagnostic tool, injection of BTX can identify those cases of whiplash disorder that are primarily myogenous in nature.
