Maine Medical Center has invested in a full array of the most advanced technology for diagnosing cerebrovascular conditions, including:
- Bi-plane angiography – An advanced x-ray system that produces exceptionally precise anatomical images for diagnosing and treating arteriovenous malformations (AVMs) and aneurysms, as well as other vascular abnormalities. It differs from traditional angiography by providing images from two different angles at the same time, significantly reducing procedure time as well as risk to the patient since the neurosurgeon and neuroradiologist can view the brain and arteries three-dimensionally with a single injection of radiographic dye.
- CT angiography – High-speed computed tomography (CT) scanning, which enables doctors to quickly and non-invasively determine the type of stroke a patient is having.
- MR angiography – Using magnetic resonance imaging to visualize blood vessels (magnetic resonance imaging uses a special magnet and computer instead of x-rays to see inside the body).
- Perfusion imaging – A special type of CT or MRI that uses an injected dye in order to see blood flow through tissues.
- SPECT (single photon emission computed tomography) uses radioactive materials injected through a vein that pass into the brain, generating a high-resolution image. A substance called Diamox is used to increase blood flow to the brain for certain SPECT tests.
- Doppler ultrasound – This test uses reflected sound waves to evaluate blood flow.
