Overview of Diagnostic Imaging
Our physicians work with the most sensitive high-resolution imaging available, from digital x-rays of the chest to guided needle biopsies.
If a mass on the lungs is suspected, a computed tomography (CT) scan may be recommended to provide more precise information. During a CT scan, imaging equipment rotates around the patient taking x-ray images in thin cross sections called slices. These slices are then combined to create a 2-D or 3-D image.
Positron emission tomography (PET) scans provide information about lesions by evaluating the function and structure of a specific organ or tissue. Patients receive a tiny amount of a short-acting radioactive substance through an IV, and then lie still while a painless scanner slowly moves over the area of concern, providing information about specific anatomy and how well cells and tissues are working.
In some cases of nodules or tumors, our combination PET/CT scanner joins data about how well certain types of cells are working with anatomical images to help distinguish benign from malignant tumors and to explore other forms of lung disease.
