What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

Key facts

CT Guidance for radiation treatment of Unspecified body region-- WO and W contrast IV

Guidance for radiation treatment^WO & W contrast IV

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] or CT WO & W contrast (this term), magnetic resonance imaging (MR) [LOINC: 82123-1] , positron emission tomography (PT) [LOINC: 82126-4] and ultrasound (US) [LOINC: 82124-9].
