ACADEMIC RADIOLOGY. Comparison of Coronary Computed Tomography Angiography-Derived vs Invasive Fractional Flow Reserve Assessment

Stefan Baumann, MD, Matthias Renker, MD, Svetlana Hetjens, PhD, Stephen R. Fuller, BSc, Tobias Becher, MD, Dirk Loßnitzer, MD, Ralf Lehmann, MD, Ibrahim Akin, MD, Martin Borggrefe, MD, Siegfried Lang, PhD, Julian L. Wichmann, MD, U. Joseph Schoepf, MD

Objectives: Invasive coronary angiography (ICA) with fractional flow reserve (FFR) assessment is the reference standard for the detection of hemodynamically relevant coronary lesions. We have investigated whether coronary computed tomography angiography (cCTA)-derived FFR (fractional flow reserve from coronary computed tomographic angiography [CT-FFR]) measurement improves diagnostic accuracy over cCTA.

AMERICAN JOURNAL OF ROENTGENOLOGY. Transradial Approach for Hepatic Radioembolization: Initial Results and Technique

Vivian L. Bishay, Derek M. Biederman, Thomas J. Ward, Imramsjah Martijn J. van der Bom, Rahul S. Patel, Edward Kim, Francis S. Nowakowski, Robert A. Lookstein and Aaron M. Fischman

OBJECTIVE. The transradial approach (TRA) has been shown to reduce the morbidity and mortality associated with arterial coronary interventions. Selective internal radiation therapy (SIRT) performed via the TRA can enhance patient comfort, compared with the traditional transfemoral approach (TFA), by allowing immediate ambulation and precluding potential complications associated with the TFA, such as closure device injury or retroperitoneal hematoma. We report our initial experience with and technique for using the TRA for SIRT.
