Modified Reiff Score for Bronchiectasis CT Severity

Evaluates the extent of bronchiectasis through site, type and extent on CT imagistic.

Refer to the text below the score for more information on its interpretation and use in studies.


Since its introduction, the modified Reiff score has been used in several studies to assess the radiological severity of bronchiectasis through the number of lobes involved (with the lingula considered to be a separate lobe) and the degree of dilatation.


The modified Reiff score originates from a study by Reiff et al. investigating whether the pattern and distribution of bronchiectasis from CT scans can be used to discriminate between bronchiectasis idiopathic and specific causes.

The maximum score is 18 and the result may be interpreted as follows:

Modified Reiff Score Bronchiectasis severity
1 - 6 points Mild bronchiectasis
7 - 12 points Moderate bronchiectasis
13 - 18 points Severe bronchiectasis

Please select the degree of dilation for the lobe(s) involved, up to six.
Note that the lingula is considered to be a separate lobe.
L1What is the degree of dilation of 1st lobe?
L2What is the degree of dilation of 2nd lobe?
L3What is the degree of dilation of 3rd lobe?
L4What is the degree of dilation of 4th lobe?
L5What is the degree of dilation of 5th lobe?
L6What is the degree of dilation of 6th lobe?

Modified Reiff Score explained

High resolution CT scan of the thorax (HRCT) is the imaging gold standard for diagnosing bronchiectasis and evaluating the extent, as well as it’s progress in cystic and non-cystic fibrosis.

The modified Reiff score assesses the radiological severity of bronchiectasis through the number of lobes involved (with the lingula considered to be a separate lobe) and the degree of dilatation:

  • No bronchiectasis (0 points)
  • Tubular (1 point)
  • Varicose (2 points)
  • Cystic (3 points)

The maximum score is 18, where the higher the score the greater the degree of pulmonary affectation. Scores can be interpreted as follows:

Modified Reiff Score Bronchiectasis severity
1 - 6 points Mild bronchiectasis
7 - 12 points Moderate bronchiectasis
13 - 18 points Severe bronchiectasis

The modified Reiff score has been used in numerous studies to evaluate bronchial dilatation on a lobar basis.

 

About the original study

The modified Reiff score originates from a 1995 study by Reiff et al. investigating whether the pattern and distribution of bronchiectasis from CT scans can be used to discriminate between bronchiectasis idiopathic and specific causes.

The extent, site, type and lobar distribution and the severity of the bronchial dilatation and bronchial wall thickening were scored via this new scoring system.
