Factors affecting patient enrollment in radiology clinical trials: a case study of the American College of Radiology Imaging Network.
RATIONALE AND OBJECTIVES: This study was designed to identify factors that affect the enrollment of patients into American College of Radiology Imaging Network clinical trials. MATERIALS AND METHODS: A quality improvement study was performed. Brainstorming produced an exhaustive list of factors that could affect the interest of sites in participating in American College of Radiology Imaging Network trials, as well as factors that could influence patient recruitment. Surveys, structured interviews, and benchmarking were used to validate and rank the importance of these factors. RESULTS: Site participation was influenced mainly by the support of the department chair and the interest of the investigator. Patient recruitment was affected primarily by the ease of identifying candidates and the perceived experience level and skill of the support staff. CONCLUSION: Because radiologists do not control patient referrals for imaging tests, a premium must be placed on developing systems to maximize the identification and enrollment of candidates for clinical trials. Other factors considered critical to success in patient enrollment include the supportiveness of the departmental leadership, the experience and skill level of study personnel, and the availability of site-specific infrastructure to support the study.

Challenges and opportunities for in vivo imaging in oncology.
Advances in genomics, proteomics and technology are changing medicine in fundamental ways. There are increasing clinical and laboratory requirements to obtain cellular and molecular information in vivo. This is particularly true in oncology, where the behavior of tumor cells is inextricably linked to their milieu. If cancer cells are removed from their microenvironment, their pattern of gene expression changes. Therefore, non-invasive, quantitative means of detecting gene and protein activity are essential. In vivo imaging is one methodology for achieving this. Marked advances in tracer methods for PET scanning or single-photon nuclear medicine techniques have occurred in the past few years. MRI contrast agents that reflect physiologic information are also being developed, although larger mass quantities of injectable material are required. The useful concept of "activatable agents" was pioneered in MRI. Similarly, ultrasound and computed tomography are being re-engineered to reflect information at the cellular level. In vivo optical imaging technologies have matured to the point where they are indispensable laboratory tools for small animal imaging. Human applications are in the feasibility testing stage, and the future for clinical optical imaging techniques looks bright. Merging these molecular imaging techniques with minimally or non-invasive image-guided therapeutic delivery techniques is a subsequent goal in the fight against cancer.
