Hepatic vascular tumor screening is better from an economic standpoint with CT and better from a diagnostic accuracy standpoint with MRI.
Currently available imaging tests to diagnose hepatic hemangiomas include both CT and MRI. However, enhanced MRI is more specific in diagnosing hepatic hemangiomas. MRI is also much more expensive than CT in terms of price point.
Enhanced magnetic resonance examination of hepatic hemangioma shows low signal in T1-weighted signal and high signal in T2-weighted signal, with uniform intensity and clear edge, which is its specific manifestation and is called light bulb sign. Enhanced CT shows obvious enhancement or edge nodular enhancement in the arterial phase, and the contrast agent gradually fills the center in the venous and delayed phases, but it lacks the specific manifestation of hepatic hemangioma.
Imaging examination for hepatic hemangioma can be chosen in accordance with the specific situation. If the economic conditions do not allow, the more economical CT examination is preferred; if the economic conditions allow, the accuracy of magnetic resonance examination is higher.
