This CME activity will present and discuss online an accepted manuscript in JCMR with the title, "Pulmonary blood volume measured by cardiovascular magnetic resonanc: influence of pulmonary transit time methods and left atrial volume."
What is the current state/problem in practice?
Objective quantification of congestive heart failure is challenging. The current state is that most cardiologists and other health care providers, including those within the field of CMR, does not know that it is possible to quantify pulmonary blood volume (PBV) as a biomarker of congestive heart failure, and that this measure can be achieved as a by-product of first-pass perfusion sequences by multiplying the pulmonary transit time with the cardiac output.
What is the ideal state if the problem is gone?
Measurement of the pulmonary blood volume (PBV), as a by-product of standard first-pass myocardial perfusion and cardiac output, becomes standard procedure and provides incremental value in terms of diagnosis, staging of various heart diseases, and evaluation of therapeutic response.
Following this activity:
1. Learners need to know that 1) an increase in pulmonary blood volume (PBV) is a biomarker of congestive heart failure, 2) that the PBV can be quantified by CMR whenever myocardial first-pass perfusion exams are performed, and 3) that the PBV assessed by first-pass perfusion is overestimated by the volume of the left atrium.
2. Learners need to apply calculation of the pulmonary transit time (PTT) and pulmonary blood volume (as PTT x cardiac output) when first-pass perfusion exams are performed.
3. Learners need to assess when to incorporate the pulmonary blood volume into clinical reports and to clarify if the left atrial volume (LAV) is included in the PBV measurement.
