The practice of medicine requires the thoughtful gathering and consideration of historical and physical examination findings, allowing the clinician to synthesize an appropriate plan of care that best serves the needs of the patient and their family. The variation of presentation of disease and trauma pathology can make this process complex. In clinical practice, this process may be simplified and a working diagnosis supported or repudiated through the use of ancillary testing as a complement to this process. However, constraints of time, available institutional resources, patient financial concerns, and the innate clinician desire to arrive at a diagnosis, especially a correct one, all factor into the utilization of available testing modalities a clinician may choose from. Radiographic testing is employed quite frequently in the emergent or urgent setting. There are myriad diagnostic imaging modalities available today. This, along with advances in imaging technology and techniques, can present the clinician with a dilemma: which modality to use? Additionally, particularly in the pediatric patient, there are concerns about ionizing radiation. While the degree of ionizing radiation exposure can be attenuated by pediatric-specific imaging protocols and improved imaging techniques, it remains a significant concern. An effort should be made to employ appropriate imaging technology that minimizes ionizing radiation exposure by adhering to ALARA (As Low As Reasonably Achievable) guidelines. Difficulty potentially arises when a clinician, tasked with managing multiple patients of differing levels of clinical severity, speaking to families, and working with other medical professionals, is burdened by not always having easy access to these accepted and recommended guidelines in a concise and organized resource.
