The SECOND way to measure is right, because the second measurement (after the length) is the transverse diameter ("from left to right"), whereas the third measurement should be the antero-posterior diameter, i.e., along the plain of the transduser, plased transvrrs to the long axis of the body.

I get a little frustrated at techs who do their sag spleen making sure they're lined up with the ribs intercostally (no rib shadows) but when they do what they call "transverse" they use the same window, rotate the transducer 180 degrees (creating essentially a mirror image of the sag, still with no rib shadows) and label it transverse. if you want a true transverse, you need to rotate 90 degrees, not 180, and you will always have rib shadow in the transverse from the same window as the sag, but that's the most accurate measurement of the splenic width.
easiest way for me is to measure length in sag, and in mid-renal transverse make sure your measurements are 90 degrees to each other. There may be disagreement over which of those is AP and which is Width, but at least you're guaranteed your renal volume measurements are spot-on.
Our hospital for some reason wants us to measure the spleens a / b length and with both in the transverse plane. I hate it and I'm not sure why they want it that way, the only other thing that we do the A/p measurements in transverse for are thyroid nodules.
