Which imaging finding excludes the diagnosis of TIA?
Understand the Problem
The question is asking about the specific imaging finding that would definitively rule out a Transient Ischemic Attack (TIA) diagnosis. This involves understanding the implications of various brain imaging results in the context of TIA.
Answer
Presence of acute infarction on MRI or CT scan excludes the diagnosis of TIA.
An imaging finding that excludes the diagnosis of TIA is the presence of acute infarction on MRI or CT scan.
Answer for screen readers
An imaging finding that excludes the diagnosis of TIA is the presence of acute infarction on MRI or CT scan.
More Information
A transient ischemic attack (TIA) is typically marked by temporary neurological dysfunction without permanent damage. Detection of acute infarction, which implies lasting brain tissue damage, contradicts this definition and thus excludes TIA.
