## Overview

[edit | edit source]

PET scan can be very useful to detect tumor size, grade and location. Primary tumor size, tumor histologic grade, and tumor anatomic locations have been shown to correlate with patient outcome in general sarcoma tumor populations.

## PET

[edit | edit source]

* Positron emission tomography (PET) scan is used in clinical practice in order to detect tumor location, histological grade and size, there is a correlation between patient outcome in sarcomas and these criteria. Larger tumors have shown to uptake more radioisotope on PET scan. A more accurate description of tumor is provided and guide physicians in their treatment options. [1]

## Bone Scan

[edit | edit source]

* Whole body bone scan or PET-CT scan are widely available and most sensitive and specific methods to detect metastasis to bones. [2]
