Overview

Other diagnostic studies for [disease name] include [diagnostic study 1], [diagnostic study 2], and [diagnostic study 3].

Bone Scintigraphy

Bone scan uses bone-seeking radioactive materials (radiopharmaceuticals) and a computer to create a picture of the bones. It is used to look for bone [[metastases] in people who have:

Bone pain
Blood chemistry tests that suggest that cancer has spread to the bone, including higher than normal levels of

PET scan

PET scans use fluoro-18-2-deoxyglucose (FDG) to evaluate solitary pulmonary nodules.

Pulmonary ventilation/perfusion scan

A pulmonary ventilation/perfusion scan (lung scan or VQ scan) is a nuclear scan that uses 2 tests to look at the blood supply of the lungs and how well air moves through the lungs. It is used if doctors are considering surgery as a treatment option. This test helps make sure that a person’s remaining lung is healthy and that the person will be able to tolerate surgery.

A chest x-ray is done before the VQ scan so the doctors can compare the results of both tests.

In the perfusion scan, a radioisotope is injected into a vein. A scanning machine is used to look at the lungs as the blood with the radioactive particles flows through the arteries of the lungs. The pictures from the machine show any problems with the blood supply of the lungs.

During the ventilation scan, the person breathes a radioactive gas through a mask while the scanner is used to watch the air flow in the lungs.
