Figure Lengend Snippet: Measurement of defect diameters with MPR in 3D TEE and comparison with 2D TEE. The length ASD of the was measured as 1.78 cm on 2D TEE mid-esophageal short-axis imaging ( a ). The same defect was measured as 2.08 cm in bicaval examination with 2D TEE ( b ). Display ASD diameters in multiple planes to generate MPR from 3D TEE zoom mode examination datasets ( c , d ). Length measured from the anteroposterior (short-axis-minimum diameter) aperture plane (red line) in multi-planer examination (1.78 cm defect measured in 2D TEE) ( c , e , f ). Again, the specified length (measured by 2D TEE) from the superoinferior (bicaval-long-axis-maximum diameter) aperture plane (green line) is seen as 2.08 cm ( d – f ). Naturally, in the final image created with MPR as a result of combining the planes (indicated by red, green, and blue lines), it is seen that the defect is ellipsoid, and the real minimum diameter (D1 yellow line-short axis) is 1.48 cm, the real maximum diameter (D2 yellow line-long axis) is 2.69, measured in cm ( e ). MPR, multiplanar reconstruction; 2D, two-dimensional; 3D, three-dimensional.
