Stereotactic Interstitial Radiosurgery With the Photon Radiosurgery System (PRS) for Metastatic Brain Tumors: A Prospective Single-Center Clinical Trial

Interstitial radiosurgery with the PRS requires continued investigation. It allows for an immediate and potentially cost-efficient treatment for patients with singular, small (≤ 6.36 cm3; or ≤ 2.3 cm) spherical brain metastasis subsequent to a stereotactic biopsy.
