Hepatocellular carcinoma treatment response: Imaging findings and criteria

Table 1 Imaging technique

	CT	MRI	CEUS
Availability	Broadly available	Limited accessibility	Limited accessibility
Costs	Less expensive	High	Less expensive
Radiation exposure	Moderate	None	None
Time taken	Fast	Long	Fast
Advantages	Good soft tissue contrast	High soft tissue contrast; Problem-solving technique	High temporal resolution; No nephrotoxicity of contrast agents
Limits	Nephrotoxicity of contrast agents; Radiation exposure	Claustrophobia; Metal and medical implants (e.g., peace-makers) due to magnetic field pulses	High level of operator expertise; Deep lesion location Patient obesity

CT: Computed tomography; MRI: Magnetic resonance imaging; CEUS: Contrast enhanced ultrasound.
