Stroke Diagnostics

When Stroke Strikes

Geisinger specialists use many tools to gather vital information about the site of a stroke and the person’s condition afterward. In many cases, these tests help specialists identify problems before they occur.

Transcranial Doppler — Like Doppler radar that pinpoints weather fronts, this type of ultrasound measures the speed and change of blood flow in the arteries leading to the brain.

MRI and CT — These scans generate hundreds of images in milliseconds, then create 3-D pictures of the brain for physicians to review.

Electrophysiology — EEG tests can help doctors determine how well the brain is functioning after a stroke.

Neuroradiology — When a patient is in the middle of a full-blown stroke, this imaging technique guides neurosurgeons to the blood clot or vessel that has ruptured. They insert a catheter through the groin, threading tiny repair instruments up to the site. This emergency procedure saves brain tissue — and lives. And it can only be done at select hospitals like Geisinger.

Telestroke — Diagnosis on the Line

The best place to go if you suspect you’re having a stroke is your nearest hospital emergency department. Geisinger can still be there for you if you live closer to another hospital.

Within minutes, neurologists from Geisinger’s telestroke program can connect online to emergency departments throughout the state, saving precious time.  A super-fast phone line transmits vital signs while you and your local doctor talk with your Geisinger neurologist about your symptoms. These virtual consultations have proven to save lives.
