Cardiac CT Anatomy
- J.F. Paul
Knowledge of the coronary anatomy is mandatory for interpreting coronary CT
angiography, since the localization of lesions may have important implications on patient care. It
is also important for recognizing anatomical variants and distinguishing benign from malignant
ones. A malignant course may be the cause of sudden death, especially in young persons during
physical activity.

Technical Considerations
In an in vitro study of prosthetic heart valve imaging, researchers examined
the impact of tube voltage variation, metal artifact reduction filter use, and iterative image
reconstruction as possible means to reduce artifacts and optimize quality.

Chest
A retrospective study explores how MDCT can be used to evaluate endobronchial
stenosis, support decisions on stent choice, and assess patients after stent placement. With an
editorial comment on the history of stenting and the importance of this new study.
