Validation of Low Dose CT for Diagnosis of Lung Nodules

Validation of an Extremely Low Dose Computed Tomography Protocol for Diagnosing Lung Nodules in Children and Young Adults

The investigators have developed an extremely low dose computed tomography (CT) protocol that on preliminary testing has an effective dose in the range of two chest radiographs. The investigators plan to test this exam in patients with known or suspected cancer undergoing clinically indicated chest CT.

Inclusion Criteria:

• Pediatric and young adult patients (ages 4 to <21 years)
• Known or suspected malignancy other than lymphoma
• Undergoing clinically indicated CT of the chest

Exclusion Criteria:

• Pregnancy identified by routine Department of Radiology verbal screening
• Prior enrollment in the same study (no patient will be enrolled more than once)
• Inability to provide consent and/or assent
• Lymphoma
