With this scan we are looking for evidence of tiny nodules which could be the early signs of lung cancer. CT scanning is the most sensitive means of detecting lung cancers and with our experienced specialist chest radiologists, we have detected cancers as small as 1-2 mm.
It is far more sensitive than X-rays which can generally only detect tumours of 10mm in size, and MRI scanning which just cannot accurately image the chest at all.
The CT scan will also show up any areas of fibrosis or previous asbestos exposure, as well as signs of chronic infection and bronchiectasis.
