A variety of imaging modalities, including ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI), nuclear medicine, and angiography are currently used in evaluating patients with various liver diseases. During the past few years, technical progress has been considerable and novel applications of US, multidetector (MD)CT, MRI have been implemented in the clinic. For example, imaging studies play a crucial role in the diagnosis and staging of HCC and currently, improvements in imaging technology make a noninvasive and reliable diagnostic assessment of hepatocellular nodules possible in the cirrhotic liver. Currently available advanced US techniques in the evaluation of liver diseases are various harmonic imaging techniques with contrast agents, volume imaging, and recently, US elastography, that has been developing and might play a role in staging of liver fibrosis and characterizing liver nodules in the future. The most recent advance in CT is the MDCT scanner. Recently, a 256 or 320 detector CT was introduced. Recently studies describe the high sensitivity of double arterial phase imaging in hepatic tumor detection and the usefulness of CT angiography by using MD CT in a detailed assessment of hepatic arterial anatomy using 3 dimensional dataset. In addition, perfusion CT imaging is being developed recently, and can be used for the functional evaluation of liver diseases as well as liver tumors before and after treatment. Dual -energy CT with new technology is also continuously progressing. Recent advance in MR technology, including hardware and pulse sequence implementation, allows acquisition times to be reduced to the time frame of one breathhold ,providing multiphasic dynamic MRI. Further improvement of imaging technologies including functional imaging such as elastography, perfusion imaging and diffusion imaging, and development of new contrast media will undoubtedly improve the detection and characterization of liver diseases as well as focal liver lesions. In this presentation, I will present a summary of the most recent information on the state of the art liver imaging.
