Perfusion

The perfusion technique is a dynamic study of the perfusion of an organ at the level of small vessels, which detects regions with pathological perfusion.

In oncology, this helps identify tumours (high/low perfusion) and to assess more aggressive regions, since the total extent of the tumour can be estimated.
Through this procedure, the perfusion technique helps select the most appropriate treatments (surgery, radiotherapy or chemotherapy), as well as design/plan radiotherapy once the exact tumour volume is known.

Another significant possibility the technique offers, besides the response degree to the therapy, is the early detection of relapse regions.
