What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Multisection^W contrast IV. It is commonly used with the system or sample type Chest>Lung parenchyma.

When is it used?

  • Used in lab systems, EHRs, and clinical data exchange.
  • May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
  • Status: ACTIVE
  • Order vs observation: Both
  • Method: CT

What it does not mean

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

Key facts

  • CT Lung parenchyma W contrast IV
  • Multisection^W contrast IV
  • High-resolution computed tomography (CT) uses thin-section axial tomography and a computer-image reconstruction algorithm, which produces less smoothing at interfaces, thus providing better delineation of small structures and detail. HRCT differs from the conventional CT in that it uses a very narrow x-ray beam collimation (1-1.3mm slice thickness compared to conventional 8-10mm) and a so-called 'high spatial frequency reconstruction algorithm'.
