Three-dimensional (3D) imaging results in highly impressive images that clearly depict internal anatomic structures and can provide diagnostic information beyond what is available in other radiologic imaging modalities. However, the postprocessing image reconstruction needed to create these studies can require considerable staff resources and advanced training. This article will describe the current role of 3D technologists, discuss the different challenges presented with onsite or outsourced 3D postprocessing, and present relevant case studies in a variety of medical applications currently aided by 3D postprocessing.
As technological advancements in breast imaging continue to emerge, the ability to detect small, early stage breast cancers is significantly improving. The importance of making an accurate tissue diagnosis of these early breast cancers is paramount. This article provides a brief description of the most common breast imaging modalities, a description of the most common diagnostic biopsy procedures, and a description of the most popular, current, and forthcoming therapeutic procedures.
Radiography is commonly used in the collection of forensic evidence and is especially useful for confirming the identity of both living and deceased subjects, identifying pre-existing skeletal trauma, assisting in the determination and/or confirmation of cause of death, and locating hidden foreign bodies, such as fragments of explosives and packages of illegal substances. The following article discusses the appropriate forensic imaging protocols for each situation and the legal and ethical issues involved, as well as new developments in technology, in an effort to provide the radiographer with the tools needed to function as part of the forensic team.
Breast cancer has a considerable impact on public health in the United States, and early detection through regular screening efforts has been critical in improving long-term outcomes for individuals affected by the disease. Radiologic science professionals play an important role in the breast cancer screening process, and are often the only professionals that individuals encounter during their examination. Technologists should therefore have an understanding of current mammography and magnetic resonance imaging practices, as well as the use of advanced modalities in screening applications, so that they are in a position to answer questions that arise and put their clients at ease. This article will review standard breast cancer screening modalities, risk factors that require additional screening efforts, and advanced modalities that are under development to improve the quality and utility of breast imaging.
