The Revolution within a Revolution: Personal Experiences of a Young Interventional Radiologist.

Interventional radiology (IR) has undergone a paradigm shift, and has become more clinically directed. This is particularly true with the new training programs, which are all required to have outpatient clinics, admitting services, and consult services within their hospitals. Despite these changes in education, however, many jobs still require a significant amount of diagnostic imaging work, and many established groups are reticent to allow the time and resources needed to pursue this clinical model of IR practice.

Dual energy subtraction digital radiography improves performance of a next generation computer-aided detection program.

Purpose: Computer-aided detection (CAD) has shown potential to assist physicians in the detection of lung nodules on chest radiographs, but widespread acceptance has been stymied by high false-positive rates. Few studies have examined the potential for dual energy subtraction (DES) to improve CAD performance.

Materials And Methods: Institutional review board approval was obtained, the requirement for informed consent was waived because the study was retrospective, and practices conformed to Health Insurance Portability and Accountability Act regulations.
