Answer

Contrast studies should be performed during an appropriate delay (for patients with good cardiac reserve, 50 seconds is an acceptable scan delay) when most spleens will be in the uniform phase of enhancement. [19] These postcontrast scans clearly depict the classic segmental, wedge-shaped, low-attenuation defect. [20] Less frequently, the entire spleen may be infarcted, leaving only a rim of contrast-enhancing capsule. [21]
