A Window on the Lung: Molecular Imaging as a Tool to Dissect Pathophysiologic Mechanisms of Acute Lung Disease
Table 1
Main strengths and weakness of CT, PET, and MR for functional lung imaging.
| ā | Strengths | Weaknesses |
| CT | High spatial resolution | Radiation exposure | Speed of acquisition | Limited ability to image biologic processes |
| PET | Image biologic processes | Radiation exposure | Tracer kinetic modeling | Lower spatial resolution |
| MR | High spatial resolution | Requires hyperpolarized gases to image ventilation | Radiation free | Limited ability to image biologic processes |
