LOINC Code 37441-3: CT Lung parenchyma WO contrast

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^WO contrast. 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 WO contrast
• Multisection^WO contrast
• 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'.
