Answer

Answer

The spatial resolution of MRI is generally considered to be lower than that of CT. For this reason, a group of nodes may sometimes be falsely mistaken as a single large node. Also, because of the inability to detect calcium with MRI, enlarged and calcified benign nodes may be mistaken for pathologic nodes. The cost of MRI and the artifacts due to cardiac and vascular pulsation and respiratory movements limit its usefulness in evaluating primary lung cancer in most cases; however, MRI may be useful in special circumstances.
