Response: It is well known that many physicians work with the pharmaceutical industry. In some cases, this can create conflicts of interest with physicians' other responsibilities. The Open Payments law, passed as part of the Affordable Care Act, recently made these relationships public, which now allows us to study them more systematically.

Dr Heike Daldrup-Link Associate Professor of Radiology Stanford University School of Medicine, Palo AltoMedicalResearch.com: Interview with: Dr Heike Daldrup-Link Associate Professor of Radiology Stanford University School of Medicine, Palo Alto   MedicalResearch.com: What are the main findings of the study? Answer: We use magnetic resonance imaging, a technology based on magnetic fields rather than radiotracers or x-rays. The underlying technology is not new – it has been used for tumor staging for many years. This is an advantage as MR scanners are available in nearly every major Children’s Hospital where children with cancer are treated. What is new about our approach is that we combined anatomical and functional images, similar to current approaches that use radiotracers and CT (PET/CT):  We first acquired scans that showed the anatomy of the patient very well and we then acquired scans that depict tumors as bright spots with little or no background information. We did that by using an iron supplement as a contrast agent: The iron supplement can be detected by the MRI magnet and improved tumor detection and vessel delineation MR scans. We then fused the anatomical scans with the tumor scans.
