Body scans used to produce images of bones can be difficult to interpret if metal implants, screws and plates have been inserted during surgery. The metal obscures the healing area of the bone and can produce spurious signals (artefacts) that confuse the results of an examination. These researchers aim to produce special computer programs to remove interference produced by metal implants. This should enable the junction between bone and metal to be seen in all dimensions on CT (computed tomography) scans. The research is especially relevant to children following spinal and limb corrective surgery, to the elderly following hip replacements and to those with difficult non-uniting fractures. Far greater detail should be available to assess the healing process and improve treatment.
