Applied Change Management in Interventional Radiology-Implementation of Percutaneous Thermal Ablation as an Additional Therapeutic Method for Small Renal Masses.

Interventional radiology (IR) has the potential to offer minimally invasive therapy. With this potential, new and arising IR methods may sometimes be in competition with established therapies. To introduce new methods, transformational processes are necessary.

Common celiomesenteric-renal trunk - First description of a rare combined variation of abdominal visceral arteries.

Different variations and anomalies are known of the abdominal visceral branches of the aorta, whereas concomitant variations including both renal and inferior phrenic arteries are exceedingly rare. We report the case of a 28-year-old female, presenting with stomachache, nausea and emesis. Computer tomography revealed a large common trunk consisting of the celiac trunk, both inferior phrenic and renal arteries and the superior mesenteric artery.

Cervical spine fractures in patients 65 years and older: a clinical prediction rule for blunt trauma.

Purpose: To determine clinical predictors of cervical spine fracture in the elderly and to develop a clinical prediction rule to guide appropriate imaging in high-risk patients.

Materials And Methods: Institutional review board approval was received with waiver of informed consent. A retrospective case-control study was performed on blunt trauma patients 65 years and older with cervical spine fractures and on randomly selected control subjects without fracture.

Stereotactic 11-gauge vacuum-assisted breast biopsy: influence of number of specimens on diagnostic accuracy.

Purpose: To determine whether number of specimens obtained at stereotactic 11-gauge vacuum-assisted breast biopsy with the patient prone influences diagnostic accuracy and to determine whether this number varies depending on mammographic appearance of lesions as masses or microcalcifications.

Materials And Methods: Biopsy was prospectively performed in 100 patients (median age, 55 years; range, 31-81 years) with 100 lesions that were mammographically evident as masses (n = 50) and microcalcifications (n = 50) with standardized protocol to acquire 20 specimens per lesion in three 360 degrees probe rotations at one skin entry site. Specimens were histologically evaluated sequentially, and findings were compared with results of surgical excision or of mammographic follow-up for at least 24 months.

Orbital apex injury: trauma at the junction between the face and the cranium.

Orbital apex injury is usually seen in multiply and severely injured patients who are subject to high-energy trauma. Orbital apex injury rarely occurs in isolation. By proximity, the face, the skull base, or their combination are the most likely regions to be injured in association with orbital apex trauma.

Web-based image review and data acquisition for multiinstitutional research.

Objective: In this article, we describe a user-friendly Web-based interface that allows review of images combined with integrated data collection and entry for use at multiple sites involved in a large multicenter research project.

Conclusion: The Web-based system that we present uses a commercially available Internet browser and Web platform and allows automated data entry that can be easily uploaded into standard data analysis programs. The system simplifies the complex logistics of using multiple sites and reviewers for radiology research and can preserve human subject confidentiality.
