Routine 24-hour brain imaging after intravenous tissue plasminogen activator (IV-tPA) for stroke is often standard. However, this study found that routine neuroimaging in stable patients rarely alters treatment, suggesting it may be safely avoided.
Area of Science:
- Neurology
- Radiology
- Emergency Medicine
Background:
- Current acute stroke guidelines recommend routine computed tomography (CT) brain scans 24 hours after intravenous tissue plasminogen activator (IV-tPA) treatment.
- The clinical utility of this routine neuroimaging in stable patients remains uncertain.
- This study investigated whether routine 24-hour post-treatment neuroimaging alters patient management.
Purpose of the Study:
- To evaluate the impact of routine 24-hour neuroimaging (CT or MRI) on the management of clinically stable patients treated with IV-tPA.
- To determine if routine post-treatment imaging is necessary for stable stroke patients.
Main Methods:
- Retrospective review of patients treated with IV-tPA between January 2011 and December 2013.
- Exclusion of patients who experienced neurological deterioration requiring neuroimaging.
- Abstracted data included demographics, neurological status changes, imaging results, and therapy modifications.
Main Results:
- Out of 131 included patients, 86.7% had moderate to severe initial neurological deficits.
- All patients underwent routine 24-hour neuroimaging (CT, MRI, or both).
- Only one patient (0.95%) experienced a change in management (a minor adjustment in blood pressure target) due to asymptomatic hemorrhagic transformation.
Conclusions:
- Routine 24-hour neuroimaging after IV-tPA in clinically stable stroke patients is associated with minimal changes in therapy.
- These findings suggest that routine neuroimaging may be safely omitted in stable patients.
- Avoiding routine imaging can reduce radiation exposure from CT scans and lower healthcare costs.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
