We sought to identify and describe the characteristics of molecular imaging (MI) programs in the United States and to determine the factors considered critical for their future.
In a cross-sectional study, a validated survey was sent to members of the Society of Chairmen in Academic Radiology Departments (SCARD) in the United States, and 26 variables were studied.
The response rate was 40.3%; 67.9% of the departments surveyed have an MI program. The main focus of 47.4% of departments is oncology. The number of radiologists working for the department was the only variable found to be significantly positively correlated with (1) number of researchers in the MI program, (2) number of MI modalities available, (3) total number of grants, and (4) having ongoing MI clinical trials. These four variables plus the number of federal grants and the space used by MI programs were independent of the geographical region, hospital size (number of beds), and department size (number of radiological examinations per year). All the MI programs received grants during 2005. Only 16.1% have no alliances with industry. Among all the departments, 82% identified staff training and recruitment as the keys for success; 78.57% considered oncology the most important future application of MI and cancer management the hospital service most affected by MI.
MI programs are starting to be more widespread throughout the United States, and the trend is for more academic radiology departments to become engaged in MI activities; their development is independent of department characteristics. Radiology departments strongly agreed about the key components for success of MI initiatives and the areas that will be most affected by MI applications.
我们试图识别并描述美国分子成像（MI）项目的特征，并确定对其未来发展至关重要的因素。
在一项横断面研究中，向美国学术放射科主任协会（SCARD）的成员发送了一份经过验证的调查问卷，并对26个变量进行了研究。
回复率为40.3%；67.9%的受访科室设有MI项目。47.4%的科室主要关注肿瘤学。发现该科室放射科医生的数量是唯一与以下方面显著正相关的变量：（1）MI项目中的研究人员数量；（2）可用的MI模式数量；（3）资助总数；（4）正在进行的MI临床试验。这四个变量加上联邦资助的数量以及MI项目使用的空间与地理区域、医院规模（床位数）和科室规模（每年的放射检查数量）无关。所有MI项目在2005年都获得了资助。只有16.1%与行业没有联盟关系。在所有科室中，82%认为员工培训和招聘是成功的关键；78.57%认为肿瘤学是MI未来最重要的应用领域，癌症管理是受MI影响最大的医院服务领域。
MI项目开始在美国更广泛地开展，趋势是更多的学术放射科参与MI活动；其发展与科室特征无关。放射科强烈认同MI项目成功所需的关键要素以及MI应用将产生最大影响的领域。
