Remember how you are asked to remove your jewellery during scans? Similarly PFM is a porcelain fused METAL crown.
The idea of removing any metalic objects during scans is to nullify any magnetic interferences.
Therefore it depends on the type of machinery. If it is the latest CT or MRI scan machine it might not interfere. (Observe if the person taking the scan is asking you to remove any jewellery, ask them if your PFM crown can interfere). Chances are the new generation tech of CT and MRI need not require. But the old ones might.
Next Steps
Consult the person responsible for the scan. If not, go for a Zirconia crown as it doesn't interfere.
Health Tips
If the technician asks you to get it removed and come, need not worry, you can get it fixed again or prefer an other crown which doesn't interfere with scans (such as Zirconia)

Dear Practo User,
PFM crown can interfere with both CT and MRI scans.
In CT Scan if the scan excludes the head and neck region, it can be performed with minimal artifacts. However, if the focus is on the head or oral structures, the metal substructure of the PFM crown may cause distortions.In MRI Scan PFM crowns can significantly interfere with MRI imaging, leading to substantial artifacts that may compromise the quality of the scan.
For optimal imaging results, I recommend visiting a nearby dentist to have the crown temporarily removed before the scan. It can be replaced afterward to ensure both diagnostic accuracy and dental integrity.
