Gradient-Echo T2WI magnetic resonance imaging (MRI) is most sensitive method for diagnosing cavernous hemangiomas.
MRI is such a powerful tool for diagnosis, it has led to an increase in diagnosis of cavernous hemangiomas since the technology's advent in the 1980s.
The radiographic appearance is most commonly described as "popcorn" or "mulberry"-shaped.
 Computed tomography (CT) scanning is not a sensitive or specific method for diagnosing cavernous hemangiomas.
Angiography is typically not necessary, unless it is required to rule out other diagnoses.
Additionally, biopsies can be obtained from tumor tissue for examination under a microscope.
It is essential to diagnose cavernous hemangioma because treatments for these lesions are less aggressive than that of cancerous tumors, such as angiosarcoma.
However, since MRI appearance is practically pathognomonic, biopsy is rarely needed for verification.

On ultrasound, cavernous haemangiomas in liver appeared as homogenous, hyperechoic lesions with posterior acoustic enhancement.
On CT or MRI scans, it shows peripheral globular/nodular enhancement in the arterial phase, with portions of attenuation of enhancing areas.
In the portal venous phase, it shows progressive centripetal enhancement.
In delayed phase, it shows retention of contrast.
It shows a high signal on T2 weighted images.
