  • Imaging Outcome [ Time Frame: Upon imaging ] [ Designated as safety issue: No ]
    Assessment of imaging parameters such as SNR, CNR


Enrollment: 15
Study Start Date: July 2011
Study Completion Date: April 2013
Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Gadofosveset Triodium
    Use of 0.03 mmol/Kg of gadofosveset trisodium (Ablavar)once with intravascular half life of up to 1 hr and optimal arterial imaging out to 20-30 minutes.
    Other Name: Ablavar
Detailed Description:

Specific Aim 1: To assess first-pass SNR and CNR of pulmonary MR angiography performed with 0.03 mmol/Kg of intravenous gadofosveset trisodium.

Hypothesis: Use of 0.03 mmol/Kg of gadofosveset trisodium in gradient recalled echo pulmonary MR angiography will provide a pulmonary artery SNR and CNR equal to or better than the SNR and CNR obtained using the same MR technique with 0.2 mmol/Kg of a conventional contrast agent (gadopentetate dimeglumine) and equal to or better than 0.1 mmol/Kg of intravenous gadobenate dimeglumine. Data will be compared to SNR and CNR of pulmonary MR angiogram images obtained at Washington University as part of the PIOPED III study.

Specific Aim 2: To assess SNR and CNR of breath-hold pulmonary MR imaging obtained immediately after the original first-pass breath-hold pulmonary MR angiography.

Hypothesis: SNR and CNR of pulmonary MR angiography performed immediately after first-pass breath-hold pulmonary MR angiography will be at least equal to the SNR and CNR obtained using the same MR technique with 0.2 mmol/Kg of a conventional contrast agent (gadopentetate dimeglumine) and at least equal to 0.1 mmol/Kg of intravenous gadobenate dimeglumine.

Specific Aim 3: To assess SNR and CNR of lower extremity MR venogram (MRV) performed immediately after the two pulmonary MR angiograms, described above.

Hypothesis: SNR and CNR of passive lower extremity MRV performed after pulmonary MR angiography will be equal to or better than the SNR and CNR obtained using the same passive MRV technique with 0.2 mmol/Kg of a conventional contrast agent or 0.1 mmol/Kg of gadobenate dimeglumine. Again, data will be compared to SNR and CNR of lower extremity
