Simulation center training as a means to improve resident performance in percutaneous noncontinuous CT-guided fluoroscopic procedures with dose reduction.
The purpose of this study was to evaluate the effectiveness of a multifaceted simulation-based resident training for CT-guided fluoroscopic procedures by measuring procedural and technical skills, radiation dose, and procedure times before and after simulation training. ⋯ CT simulation training decreases procedural time, decreases radiation dose, and improves resident efficiency and confidence, which may transfer to clinical practice with improved patient care and safety.

Improvement in diagnostic accuracy of ultrasound of the pediatric appendix through the use of equivocal interpretive categories.
The purpose of this article is to evaluate the diagnostic performance of ultrasound of the pediatric appendix using standardized structured reports that incorporate equivocal interpretive categories. ⋯ Appendix ultrasound examinations interpreted according to a scheme that incorporates equivocal categories better convey diagnostic certainty and increase diagnostic accuracy compared with a binary interpretive scheme.

1. CT radiation dose optimization is one of the major concerns for the scientific community. 2. ⋯ Tube current is the most common parameter used to reduce radiation dose along with iterative reconstruction. 5. Tube potential (kV) is also used for dose optimization with iterative reconstruction in CT angiography protocols and small patients.

Comparative StudyRadioactive seed localization versus wire localization for lumpectomies: a comparison of outcomes.
The purpose of this study was to compare outcomes of radioactive seed localization (RSL) versus wire localization using surgical margin size, reexcision and reoperation rates, specimen size, radiology resource utilization, and cosmesis as measures. ⋯ RSL is an acceptable alternative to wire localization and offers significant improvements in workflow.

Dysphagia secondary to anterior cervical fusion: radiologic evaluation and findings in 74 patients.
The objective of our study was to assess the frequency, cause, and time course of dysphagia after anterior cervical fusion (ACF). ⋯ Dysphagia is an underrecognized but significant complication of ACF. After ACF, 4.1% of patients presented for radiologic evaluation of dysphagia. Although ACF procedures are most frequently performed in the lower cervical spine, dysphagia is a more common clinical problem after ACF in the mid cervical spine. Radiologic examinations should be specifically tailored to evaluate ACF patients.
