What is the difference between stereotactic radiosurgery and fractionated stereotactic radiotherapy?
Treatment is either applied in a single session with a high dose of radiation, known as stereotactic radiosurgery (SRS), or in a series of treatments over a period of time, known as fractionated stereotactic radiotherapy (FSRT). Fractionated stereotactic radiotherapy involves a similar total dose of radiation as stereotactic radiosurgery, but the radiation is delivered in smaller amounts. According to the experimental biology of tissue response to radiation, fractionated stereotactic radiotherapy allows the healthy tissue to recover from the impact of the radiation before the next treatment session. Your doctors will recommend the technique most appropriate for you, depending on the size and location of your tumor. For fractionated treatments, a face mask is worn instead of the metal head frame. Each face mask is formed to perfectly fit onto each patient’s head and unique facial shape.
