Hemangiomas, especially typical or larger ones, can generally be identified or diagnosed through a CT scan. However, for smaller hemangiomas, a plain CT scan usually cannot conclusively diagnose the condition. For a definitive diagnosis of a hemangioma, an enhanced CT scan can be conducted. This type of CT scan can typically diagnose the disease and also help differentiate hemangiomas from other types of tumors. Therefore, for patients with hemangiomas, if they wish to use CT for diagnosis and examination, it should be combined with some color Doppler ultrasound and, if necessary, some MRI or enhanced CT scans for further diagnosis.
