  • Method: PT

What it does not mean

  • The code identifies the observation or test, not the actual result.

Key facts

PT Guidance for radiation treatment of Unspecified body region
Guidance for radiation treatment
One of the first steps in radiation oncology treatment planning is radiation simulation, during which detailed imaging is done to show the precise location of a patient's tumor and the surrounding healthy tissue. This information guides treatment planning in that it is used to determine the optimal patient positioning, to mark the patient's skin with small dots of permanent ink (tattoos) to ensure that the same precise area is treated each time, and to create custom immobilization devices such as a face mask or a leg mold. Various modalities may be used for radiation simulation to guide radiation treatment planning, including computed tomography (CT) [LOINC79072-5], magnetic resonance imaging (MR) [LOINC: 82123-1], positron emission tomography (PT) [LOINC: 82126-4] and ultrasound (US) [LOINC: 82124-9].
