PET/CT Scan For Cancer Diagnosis

A PET scan (Positron emission tomography and computed tomography) scan is crucial diagnostic procedure for cancer detection and evaluating the extent of cancer. This diagnostic procedure uses low radiation and a radioactive tracer to detect malignant growth in any part of the body. This test detects the cellular changes in organs and tissues as well as identifying the abnormally active cells. It helps in detecting the cancer and its spread. PET CT scans provide the clear insight needed to diagnose the problem and determine the treatment options.

The price of a PET CT scan for a cancer problem is Rs. 22000 to Rs. 30000. At different PET CT Scan Centre, locations in different cities, the price varies.

Conclusion

PET CT scan for cancer is a very useful imaging procedure for detecting or diagnosing cancer and treating it effectively.
