Pulmo CT
• Examinations should be acquired at the same res-
piratory level, usually at either full inspiration or full
expiration. Studies had shown that reproducibility
is high and is unlikely to be improved by using spiro-
metric gating [1].

Siemens Reference Data
It was acquired from lung healthy individuals at 50%
vital capacity. Since Pulmo CT program does not pro-
vide spirometric triggering for the acquisition of the
data set, it is not meaningful to use Siemens reference
data for comparison unless the data is acquired under
the same conditions.
User-Specific Reference Data
It is possible to integrate in your own reference data,
e. g. data acquired at full inspiration, for the evaluation.
Please contact the local Siemens representative for
further information.
How to do it
It is recommended to end the exam first, and then
start the Pulmo evaluation.
Select the images that you want to evaluate, and
activate the program by clicking on the “Pulmo” icon.
