PET scan is a sensitive investigation for many tumors. Angiosarcomas can also be picked up by PET scan. However, a PET scan (about Rs 20000) is relatively expensive compared to a CT scan (5000 - 10000) or MRI (~10000). If the sequential CT scans are normal and if your brother does not have any complaints on regular follow up then he might not require a PET scan. If on the other habd there is some abnormality on the CT which is difficult to make out then you can go for a PET scan especially to see if there is active tumor or fibrosis. Lot of places now offer PET scan. An idea of your location would help give a specific answer.

Hi Sangeetha,

PET scan (Positron emission tomography) is a recent advancement in the field of medicine. It helps in analyzing the spread of cancer cells in the body. A dye is injected and serial photographs are taken after sometime. The cancer cells take more of this dye and the photograph taken shows the concentration of the dye in the particular place of the body. This is how the spread of the tumor or the remnant of the tumor can be found out. Almost all the cancer centers in our country has this set-up.
