Why do we need lung enhancement CT?

Lung space-occupying lesions first need to do lung enhanced CT reasons are relatively many, generally speaking, according to the actual CT film to judge, such as space-occupying lesions in the lungs, lung nodules or lung cancer, in this case ordinary CT may not be able to make a clear diagnosis, need to do enhanced CT. In addition, some lung inflammation after treatment effect is not good, in this case need to do enhanced CT to rule out the possibility of other lesions. In addition, for some tumor patients, enhanced CT is also needed for reexamination after treatment, which can rule out whether there is metastasis, so whether enhanced CT is needed for patients depends on the condition.
