What imaging study should be obtained urgently if intracranial hemorrhage is suspected after thrombolysis?

• A. Non-contrast CT head
• B. MRI brain
• C. CT angiography
• D. Ultrasound of the abdomen

Answer: (A)

The urgent imaging idea here is to rapidly check for bleeding in the brain, and the fastest, most reliable way to do that is a non-contrast CT scan of the head. It can be performed within minutes, is almost universally available in emergency settings, and clearly shows acute blood as a hyperdense area. This lets clinicians quickly confirm or rule out intracranial hemorrhage, which is critical after thrombolysis because confirming a bleed will change management immediately (stopping anticoagulation, reversing effects, and guiding supportive care). MRI brain can be more sensitive in some scenarios, but it takes longer to perform, often requires transferring a unstable patient, and may delay essential decision-making. CT angiography adds vascular detail and contrast, which is useful for planning interventions or evaluating vessels, but it is not the first test when the priority is rapidly identifying an intracranial hemorrhage. Ultrasound of the abdomen doesn’t address intracranial pathology. So, non-contrast head CT is the best first step to promptly detect or exclude intracranial hemorrhage after thrombolysis.
