Brief summary
Low-dose computed tomography (LDCT) is used in individuals at high risk of developing lung cancer (smokers over 50 years of age), as it allows for the identification of pulmonary nodules, which, in a small percentage of cases, may represent early-stage lung cancer. However, according to LUNG-RADS guidelines, individuals undergoing screening must repeat multiple LDCT scans, as the comparison between successive LDCT scans enables the assessment of existing nodules' progression and the identification of newly developed pulmonary nodules. This results in cumulative exposure to ionizing radiation, increasing the risk of radiation-induced cancers. This study addresses, through the implementation of new imaging techniques utilizing the latest and most advanced technological innovation (high-field 3T Magnetic Resonance Imaging (MRI) with artificial intelligence), the critical challenge of reducing radiation exposure in current LDCT-based screening programs, proposing the use of MRI as an alternative screening method to LDCT.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| the sensitivity and specificity for lung nodule detection of a Single Breath- Hold Lung non-contrast MRI scan (SBH-Lung-MRI), lasting less than 20 seconds, in comparison to LDCT | 3 years |
Secondary
| Measure | Time frame |
|---|---|
| the sensitivity and specificity for lung nodule detection of SBH-Lung-MRI, lasting less than 20 seconds, in comparison to two of the most accurate available sequences for MRI lung nodule detection, namely: 2D-UTE and spiral 3D- UTE MRI sequences. | 3 years |
Other
| Measure | Time frame | Description |
|---|---|---|
| The health impact of implementing a radiation-free MRI-based lung cancer screening program using the SBH-Lung-MRI approach compared to conventional LDCT screening. | 3 years | The following will be used to assess this outcome measures: number of lung cancer cases detected, stage distribution at detection, lung cancer-specific mortality, and overall mortality. |
| The cost-effectiveness of implementing a radiation-free MRI-based lung cancer screening program using the SBH-Lung-MRI approach tested in specific aim 1 compared to conventional LDCT screening. | 3 years | The following will be used to assess this outcome measures: total program costs, costs per scan, and scanner operational efficiency (e.g., cost per hour of scanner use). |
