Understanding Stroke Diagnosis and Imaging

Why is immediate diagnosis and treatment crucial when a stroke is suspected?

• To prevent heart attacks

• To save as much brain tissue as possible

• To avoid unnecessary hospital visits

• To ensure the patient gets enough rest

What is the primary purpose of a CT scan in stroke diagnosis?

• To assess lung function

• To look at the brain from different angles

• To provide a detailed view of the heart

• To measure blood pressure

What is a key feature of a normal brain on a CT scan?

• Well-delineated curves

• Asymmetrical structure

• Dark spots throughout

• Blurred edges

Why might a CT scan not show immediate changes after a stroke?

• CT scans are not used for brain imaging

• The scan is too quick to capture details

• The brain changes take time to develop

• The patient needs to be asleep

What does the MCA Hyperdense Sign indicate on a CT scan?

• A healthy brain

• A possible clot in the Middle Cerebral Artery

• A tumor in the brain

• An infection in the brain

What is the purpose of CT Angiography in stroke diagnosis?

• To detect skin infections

• To assess muscle strength

• To visualize blood vessels and identify blockages

• To measure brain temperature

How does CT Angiography highlight blood vessels?

• By using a magnetic field

• By using sound waves

• By injecting a special dye

• By applying pressure

What advantage does MRI have over CT scans in stroke detection?

• It is more sensitive in detecting brain ischemia

• It requires no special equipment

• It is faster to perform

• It is less expensive

What does a Flair MRI image show?

• The digestive system

• Only the brain tissue, excluding fluid

• The heart and lungs

• The entire body

What can MRI detect shortly after stroke symptoms begin?

• Changes in skin color

• Ischemic brain changes

• Increased heart rate

• Muscle spasms
