LOINC Code 37439-7: CT Lung parenchyma

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. 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
• Multisection
• High-resolution computed tomography (HRCT) uses thin-section axial tomography and a computer-image reconstruction algorithm, that 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'. HRCT is used to accurately assess the lung parenchyma and airways for inflammation and scarring in the diagnosis of various health problems, for example, the diagnosis and assessment of interstitial lung disease. HRCT does not image the whole lungs, therefore is unsuitable for the assessment of lung cancer or other localized lung diseases.
