Sample lung water density images. Comparison of lung water density in a healthy control and patient with heart failure after removal of blood vessels and insertion of missing pixels using linear interpolation. Using the rectangular profile analysis method (Fig. 2), the lung water density was 16.5% in the control subject and 27.1% in the patient. The patient had an elevated left ventricular end-diastolic pressure of 31 mmHg (normal ≤12 mmHg) on cardiac catheterization and a brain naturetic peptice (BNP) of 1467 pg/ml (normal < 100 pg/ml)
