Dial It Down

Dial It Down Dial it Down's Goals:

To reduce confusion about medical imaging radiation as it relates to CT scans. To increase the appropriate use of low dose CT technology.

A public awareness campaign by the Testicular Cancer Society to increase awareness about low-dose Computed Tomography (CT) technology and help reduce the risk of unnecessary exposure to ionizing radiation that is a part of necessary CT scans. To responsibly give an honest and understandable explanation about radiation as it relates to risk of developing cancer. To facilitate communications between

patients, physicians and radiology departments about opportunities to reduce radiation dose in CT. To increase patient’s awareness of their radiation exposure and previous imaging studies. To increase and encourage patient preference in selecting imaging locations with low dose CT capabilities.

What do you think? Is there a role for chest CT in the diagnosis of pneumonia?

Overdiagnosis, as well as (to a lesser extent) underdiagnosis, of pneumonia on chest radiographs is common. Low-dose CT chest can potentially be helpful, especially in cases of intermediate probability of pneumonia on chest radiography.

This phantom study got us thinking. Is there a role for sub-mSv Chest CT over chest x-ray for acute conditions such as suspected pneumonia, especially in patients with systemic inflammatory response syndrome?
