You may thus request that your data, should it be inaccurate, incomplete, unclear, outdated, not be used or stored, be corrected, clarified, updated or deleted.
Diagnosing cases of PE presents particular challenges, however; pregnancy-related physiological changes have the potential to impair image quality to such an extent that a diagnosis may no longer be possible.
Researchers conducted a survey to find out whether other imaging facilities had a specific protocol for CT pulmonary angiography in pregnant women and how satisfied they were with the quality of these types of examinations.
angooscanner In addition to the survey, the department also retrospectively analyzed examinations and the conditions in which they were performed. During CTPA, radiologists and radiographers subjectively evaluate injection quality to check for sufficient contrast enhancement of the pulmonary arteries.
