The main difference between tomography computadorizada (TC) and ressonance magnetica (RM) is their methods of imaging. The former uses radio waves to produce images while the latter uses rays-X. Both methods are good for diagnostic purposes and can also be used to monitor the efficacy of treatment.Tomography computadorizada is more accessible and inexpensive than magnetic resonance imaging. It can also differentiate moles and air. Moreover, it is more accurate and reliable than MRI, which is more invasive. You can decide which method you'd like to undergo depending on your preferences and your budget.
