2. Fig 1
Axial CT image of the thorax, cephalad to the diaphragm in a supine patient. Solid lines indicate the extent of visualization when examining the left (L) and right (R) pleural spaces using TOE. Pleural fluid (PF) pooling in the right dorsal pleural space and pulmonary atelectasis (AT) can be seen. The aorta (Ao) and vertebral body (V) are marked.

3. Fig 2
TOE images demonstrating the ‘tiger’s claw’ appearance of chronic left (L) and right (R) pleural effusions. The presence of pulmonary atelectasis (AT) means the full extent of the pleural fluid (PF) is visualized. The aorta (Ao) is marked.

4. Fig 3
TOE images demonstrating the ‘tangerine segment’ appearance of acute left (L) and right (R) pleural effusions. The dotted line marks the circumference of the pleural fluid (PF). The area within the dotted line is the maximal cross-sectional area (CSAmax). The solid line represents the maximal depth of the pleural fluid (d). The aorta (Ao) is marked.

5. Fig 4
Scatter plots showing actual volume of pleural fluid instilled against volume calculated using TOE. (a and b) TOE volume calculated using CSAmax × AL for left and right data, respectively. (c and d) TOE volume calculated using d2 × AL for left and right data, respectively.

6. Fig 5
Bland–Altman plots showing the actual volume instilled against the difference between calculated TOE volume and actual volume instilled. (a and b) TOE volume calculated using CSAmax × AL for left and right data, respectively. (c and d) TOE volume calculated using d2 × AL for left and right data, respectively. The bold line represents the linear trend. The central dotted line represents mean bias. The upper and lower broken lines represent 95% CI.
