PET-CT Clinical Usage

BRAIN        Alzheimer’s      Advancements in PET imaging have allowed for earlier diagnosis of Alzheimer’s, which can increase the opportunity to slow the progression of the disease
Seizure Disorders      The use of PET-CT has significantly assisted in being able to pinpoint the site or origin of the disorder within the brain, which may lead to a surgical removal of the involved tissue and possibly lead to stopping the seizures or lessening the impact.
Parkinson's Disease
(investigational at this time)
Assist in the analysis to determine if a muscle tremor is indication of Parkinson’s disease or some other disorder.
CANCER Types of cancers Diagnosing cancers involving lung, colorectal, esophageal, head, and neck
Lymphoma PET-CT imaging has been found to be very effective in evaluating Hodgkins Lymphoma and non-Hodgkins Lymphoma cells.
Melanoma PET-CT has been reported to be effective in staging melanoma, and very valuable in detecting and/or ruling out the metastases of the diseases to other regions of the body.
NODULE WORKUP Lung Specific Proven beneficial in the characterization of lung nodules to discover the likelihood of cancer, reducing unnecessary surgeries and biopsies.
HEART Myocardial Imaging PET-CT can demonstrate how much of the heart can be expected to recover after a revascularization procedure such as angioplasty or bypass. PET-CT may also be used in the evaluation of coronary artery disease.
