PET/CT
More than 1.4 million people will be diagnosed with cancer in 2008. There will be 36,980 new cases of cancer in Georgia alone. PET/CT imaging is the gold-standard for diagnosing and treatment planning of cancer. PET/CT scans provide complete information regarding location, size, nature and extent of cancer – anywhere in the body.
Northside began using PET (Positron Emission Tomography) in 2001 and has been utilizing PET/CT technology since 2003. PET/CT detects sites of cancer not seen by other imaging modalities, differentiating scar tissue from tumor and benign from malignant lesions. It also produces images showing metabolism or biochemical changes.
“The detailed information that a PET scan provides substantially increases the confidence that cancer diagnoses are correct and complete,” says James Weinstein, M.D., radiologist on staff at Northside Hospital.
Through use of X-rays, CT (computerized tomography) produces an accurate anatomical image of the body – a ‘slice’ of an organ or particular area. Together, PET and CT reveal a complete picture – providing both anatomic and metabolic information at one time, in stunning detail, to help physicians diagnose and localize cancer.
Before having a PET/CT scan, the patient receives a dose of a radiopharmaceutical tracer, which contains a sugar that accumulates in cancerous cells. During the scan, the tracer is detected by the system, creating an image of the patient and highlighting any abnormal physiology. This image helps physicians determine if disease is present, the location and extent of the disease and how rapidly it is spreading.

Length of procedure:
The actual PET/CT Scan will take 25 minutes. However, the entire procedure including registration, preparation for the scan, injection of the tracer, will take approximately
2 to 3 hours.
