The ALARA (As Low As Reasonably Achievable) Concept in Pediatric Interventional and Fluoroscopic Imaging: Striving to Keep Radiation Doses as Low as Possible during Fluoroscopy of Pediatric Patients—A White Paper Executive Summary
A diverse cadre of 74 pediatric radiologists, medical physicists, radiologic technologists, researchers, pediatric subspecialists and vendors met to examine the risk of radiation exposure from fluoroscopic and interventional procedures, identify means by which to reduce ionizing radiation exposure, and explore future technologic modifications that could optimize imaging while further reducing radiation exposures.

CT Imaging of Colitis
While thickening of the colonic wall is a nonspecific sign on CT images and can be seen in inflammatory, ischemic, or neoplastic processes, some CT features such as amount of wall thickening, extent of disease, pericolonic reaction, presence of ascites, formation of fistulae, and type of complication can be used to narrow the differential diagnosis.

Clinical Breast Examination in a Comprehensive Breast Cancer Screening Program: Contribution and Cost
Screening clinical breast examination is complementary to screening mammography in demonstrating breast cancer in asymptomatic patients; clinical breast examination accounted for 14 (3%) of 453 cancers detected in our study population, and the cost of detecting these cancers was approximately $122,598 per cancer.

Bayesian Network to Predict Breast Cancer Risk of Mammographic Microcalcifications and Reduce Number of Benign Biopsy Results: Initial Experience
In our pilot study, we demonstrated that a Bayesian network can (a) predict the likelihood that microcalcifications at mammography are malignant, (b) perform as well as a subspecialty-trained mammographer in estimating the probability of malignancy, and (c) improve the positive predictive value of the decision to perform biopsy.
