Iterative reconstruction in single source dual-energy CT pulmonary angiography: Is it sufficient to achieve a radiation dose as low as state-of-the-art single-energy CTPA?
With iterative reconstruction, objective and subjective image quality of single source DE-CTPA are preserved even though the radiation dose is lowered to that of a single-energy examination, overcoming a major limitation of the DE technique and allowing a widespread use in the clinical routine.
Whether the patient was given a handout or had visited the ASSH or other Internet web sites, the knowledge and satisfaction scores for all patients were similar. Since the physician was the common denominator in both groups, the results indicate that the patient-physician relationship may be more valuable than the Internet in providing patient education.
