There are four kinds of PET-CT scans performed at Providence Imaging Center, including whole body scans, brain scans, heart scans and bone scans.
Whole body scan - This scan is used to:
This scan is used to assist physicians in diagnosing many common cancers, including breast, colorectal, esophageal, head and neck, lung, lymphoma, melanoma, ovarian, pancreatic, thyroid and muskuloskeletal tumors
Identify where the cancer is in the body
Determine if the cancer has spread
Brain scan - This scan is used to:
- Differentiate recurring brain tumors from healthy tissue for targeted radiation therapy
- Before surgery for some seizure disorders
- Differentiate Alzheimer's disease from dementia that is caused by multiple mini-strokes
Heart scan - This scan is used to:
- Distinguish healthy heart muscle from non-functioning tissue after a heart attack
- Identify whether or not there is adequate blood supply to the heartEvaluate the extent of heart disease in patients being considered for heart bypass or transplant operations
PET-CT bone scan - This scan (18F-Fluoride PET-CT bone imaging) is much more sensitive than traditional nuclear medicine bone scans (99mTc). Per Bryan Winn, PIC Radiologist, it has a higher specificity for bony metastases, due to higher spacial resolution and the ability to directly compare with anatomic CT images (fewer false positives). It is primarily used to:
- Evaluate bones for abnormalities like bony lesions and tumors
- Evaluate post operative fusion patients
