Lymphoma

Brief summary

Hypothesis: Does a 50% reduction in radiation in dose significantly affect the diagnostic quality of chest CT

Detailed description

Patients with Lymphoma are recruited and have a follow up CT performed at 50% of the standard exposure parameters. The studies are compared for image quality with a recent (\<3 months) thoracic CT performed at standard exposure parameters.
