What the Diagnostic Radiologist Needs to Know about Radiation Oncology

ÌÇÐÄ´«Ã½

Abstract

Substantial technologic advances in radiation treatment planning and delivery have made possible exquisite tailoring of three-dimensional radiation dose distributions that conform to the tumor treatment volume while avoiding adjacent normal tissues. Although such highly precise treatment can increase the therapeutic ratio, it also introduces the potential that tumor extension outside the target is missed because it is unrecognized at the time of radiation treatment planning. As a result, accurate targeting of the tumor with radiation is of utmost importance to the radiation oncologist. Communication between diagnostic radiologists and radiation oncologists is essential, particularly given the subtleties that accompany image interpretation, to optimize the care of the cancer patient.
