- “Cinematic rendering (CR) is a new rendering algorithm that incorporates a more advanced lighting model than that used for VR, to create photorealistic 3D CT images. The post-processing tool is not yet widely available and its ultimate clinical utility has yet to be assessed in well-designed studies. Nonetheless, the striking level of detail and enhanced depiction of 3D anatomic relationships holds potential for improvements in diagnosis, interventional or operative planning and patient centered care.”

Retrospective and prospective gating can be used to address the motion artifact. For interpretation and display, this anatomic region is best evaluated with rendering algorithms that preserve the 3D relationships of these intertwined arteries. Accordingly, volume rendering and cinematic rendering are the optimal post-processing tools for pulmonary and aortic imaging.”

- “ Pulmonary CTA can be performed using a tube potential of 100 kVp in patients who weigh less than 100 Kg(220lb). Reducing the tube potential from 120 to 100 kVp results in a 37% reduction in radiation dose without a significant impact on diagnostic image quality.”

- “ Intravenous administration of low-osmolality contrast material is significantly associated with exacerbation of myasthenia gravis-related symptoms. Exacerbations most commonly manifest as new or progressive acute respiratory comprimise.”
