Positron Emission Tomography (PET) is an emerging modality in lung cancer staging. It allows for combination fo functional and anatomic assessment of lesions, especially useful in detecting nodal involvement or metastatic spread. Tumor cells have a higher than normal metabolism, detect on PET by their increased glucose uptake, which makes PET an excellent modality to classify indeterminate lesions, thus reducing the rate of unnecessary biopsies.

Combined PET/CT machines are a new area of research that allow for the functional metabolic discrimination of PET to be overlaid on high-resolution CT scans. Early research shows that TNM staging is more accurate with PET/CT machines than with CT alone. PET alone, or visual correlation between PET and CT. Although not widespread, combined PET/CT has the potential to be invaluable in staging and therapeutic planning.

In some instances, PET is limited by availability and expertise.  However, Diagnostic Imaging Services has been providing PET/CT examinations for three years.  We are accredited by the American College of Radiology, meeting or exceeding standards set for quality and safety.  We are the ONLY outpatient imaging provider that has every PET/CT study read by two physicians, one of whom is well-known internationally for his work and teaching in the area of nuclear medicine and PET/CT.

PET/CT examinations are completed every Friday at the D.I.S. West Bank facility located at 925 Avenue C in Marrero.
