Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
We are doing the research to see if a CT scan without the dye can help find pulmonary emboli. If you agree to join the study, you will be asked to sign this consent form before we do any research procedures. If you join the research, we will ask you to blow into a small device known as a spirometer to train you to hold your breath after you inhale and exhale. Spirometer is a small handheld device to find out how well your lungs work when you inhale and exhale. For this research, we will obtain two extra sets of CT images at very low levels of radiation dose. The two extra sets of images will take less than 1 minute. Your total participation time is about 5 minutes. We will also review your medical record for up to 30 to 90 days after your CT scan. The main risks of being in the study are exposure to ionizing radiation which may have health risks, and minor inconvenience from the spirometer test. You will not benefit from taking part in this research study. If you take part in this study, your participation may help people in the future. If you decide not to be in the study, you will still have the standard-of-care chest CT with the dye ordered by your doctor. You will not be paid for taking part in this research study.
