Answer

CT angiography and contrast-enhanced CT scanning may be considered for helping identify patients at risk for hematoma expansion. Extravasation of contrast within the hematoma indicates high risk.

When clinical or radiologic findings suggest an underlying structural lesion, useful techniques include CT angiography, CT venography, contrast-enhanced CT scanning, contrast-enhanced MRI, magnetic resonance angiography (MRA), or magnetic resonance venography. [1]
