Alzheimer’s Disease Imaging

While no one test can determine if a person has Alzheimer’s disease, imaging studies can help evaluate the presence of certain symptoms that aid in a more accurate diagnosis. In Alzheimer’s disease, large numbers of neurons stop functioning and die, which leads to loss of memory and thinking skills. Positron Emission Tomography (PET) uses small amounts of a radioactive compound or “tracer” to diagnose and determine the severity of a variety of diseases. A combined PET/CT exam merges a CT scan that provides detailed anatomy of the brain with a PET scan that shows how brain tissue function. This exam can help detect the early onset of neurological disorders such as Alzheimer’s disease, and can rule out other types of dementia.

Advanced Radiology offers Connecticut’s only permanent PET-CT scanner at an outpatient facility, which means you get the peace of mind that comes from high-quality studies that provide accurate diagnostic answers. Our radiologists review the images in real time during the scan for prompt answers for your doctor.

Brain amyloid imaging

Another way PET scanning is used to diagnose and track Alzheimer’s disease is with brain amyloid imaging. By using a newly developed radioactive tracer, our radiologists can detect the build-up of beta-amyloid plaques in the brain, which is an indicator that can help to clarify a diagnosis of Alzheimer’s disease.

Preparation

A PET/CT scan requires that you refrain from strenuous exercise for 24 hours prior to the exam. You should not drink or eat for 4-6 hours prior to the exam. If you must take oral medications, please take them with a minimal amount of water, or you may bring your medication to the office and take immediately following the study. Drinking plenty of water is encouraged prior to the exam. If you have any questions, please feel free to ask us.
