Summary

This study tests a new computer method called P-MAR that helps reduce the blur or streaks metal objects (like implants or fillings) cause in CT scans. About 120 adults with metal in their body will get standard CT scans, and the new method will be compared to existing techniques. The goal is to see if P-MAR makes images clearer and helps doctors feel more confident in their diagnosis.

Inclusion Criteria: * Subjects scanned by FDA-cleared and marketed Philips Incisive CT or CT 5300 systems, and according to the department standard of care clinical protocols. * Subject age: Above 18 years old. * Scans with metal present (orthopedic implants/joint prothesis, dental filling/implants, spine screw(s), pacemaker, coils, radiotherapy beads, surgical clips/staples, metal objects either outside the body or near air, etc.) Exclusion Criteria: * Subject age: 18 years old and below. * CT scans with no metal present. * CT scans with metal with motion artifacts. * Surview or Locator/Tracker. * CT scans performed utilizing respiratory gating (e.g., "pulmo gating"). * CT scans performed utilizing cardiac gating. * CT Perfusion scans. * CCT scans. * Scans that the site radiologists have deemed as non-diagnostic image quality in standard practice (e.g. patient movement). * Scans that are not completed due to technical difficulties.
