A good elastography study is indicated by elasticity readings greater than

Elastography relies on how much the tissue deforms under applied pressure to calculate stiffness. A good study needs enough deformation to produce a clear, reliable elastography map. If the elasticity readout is very small—say under 5%—the signal is often too weak or noisy, making the measurement unreliable. If there’s no measurement at all, you can’t interpret anything. When the reading is greater than about 29%, there’s typically enough deformation captured to generate a trustworthy elasticity map, so the study is considered technically adequate. Values like exactly 50% aren’t a standard quality threshold, and saying you can’t measure isn’t a helpful readout for a reliable study.
