Standard wellness checks are not providing sufficient detail to give patients a thorough understanding of their state of health according to the European Scanning Centre.
The current level of health check done in a wellness check is not enough to provide a sufficient level of detail for advisers and insurance companies, lacking sufficient complexity and possibly creating a false sense of security.
Paul Jenkins, medical director at the European Scanning Centre, said: "To understand what is really happening inside the body a number of different approaches are needed. Basic GP-style checks are fine in principle but to have a comprehensive understanding a series of scans are needed."
Current wellness assessments, with costs sometimes over £600 include checks on blood pressure, BMI and glucose levels.
The European Scanning Centre was set up 12 years ago and is based in Harley Street and staffed by preventive and diagnostic medical staff.
He added: "For example an MRI cannot fully image the lungs to detect early stage lung cancers, or inside the heart arteries to detect early stage atherosclerosis, which a CT scan can do. This can prevent critical illnesses occurring because we can detect them at a very early stage.
"To be able to look at someone's musculoskeletal images, either when they are in an open upright position or an image of an actual moving joint, is very beneficial for diagnosing pain and difficultly with movement."
