Overview
There is no single diagnostic study of choice for the diagnosis of stroke. But stroke can be diagnosed based on clinical presentation, CT scan, MRI findings.
Diagnostic Study of Choice
Study of choice
There is no single diagnostic study of choice for the diagnosis of stroke. But stroke can be diagnosed based on clinical presentation, CT scan, MRI findings.[1][2][3]
- Non-contrast CT scan is fast, widely-available and inexpensive. It can rule in hemorrhagic stroke (intracerebral or subarachnoid hemorrhage) with over 95% accuracy. CT scan also has the ability to rule in massive ischemic stroke in two third of cases, but is is not sensitive for minor ischemic stroke.
- MRI is the most sensitive and specific test for diagnosing ischemic stroke, specially minor ischemic stroke with limited deficits, and may help detect presence of infarction in few minutes of onset of symptoms.
Sequence of Diagnostic studies
- History and physical exam
- Non-contrast CT scan
- MRI

Head and Neck Imaging
| Class I |
| 1. All patients with suspected acute stroke should receive emergency brain imaging evaluation on first arrival to a hospital before initiating any specific therapy to treat AIS.(Level of Evidence: A) |
| 2. Systems should be established so that brain imaging studies can be performed as quickly as possible in patients who may be candidates for IV fibrinolysis or mechanical thrombectomy or both.(Level of Evidence: B-NR) |
| 3. Noncontrast CT (NCCT) is effective to exclude ICH before IV alteplase administration. (Level of Evidence: A) |
| 4. Magnetic resonance (MR) imaging (MRI) is effective to exclude ICH before IV alteplase administration. (Level of Evidence: B-NR) |
| 5.CTA with CTP or MR angiography (MRA) with diffusion-weighted magnetic resonance imaging (DW-MRI) with or without MR perfusion is recommended for certain patients.(Level of Evidence: A) |
