Novel biological therapies, including tyrosine kinase inhibitors such as sorafenib, improve the survival of patients with unresectable hepatocellular carcinoma. However, assessment of therapeutic efficacy remains challenging with conventional imaging techniques such as ultrasonography, CT or MRI that predominantly rely on size change to detect a treatment response. A beneficial tumour effect may go unrecognized in some patients who do not show tumour shrinkage and conversely, some patients may be maintained on treatment that is not active. This paper explores the use of functional imaging methods that are showing promise in the assessment of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is one of the most recurrent and lethal cancers worldwide. The low survival rate of this particular strain of carcinoma is largely due to the late stages at which it is ...
Radiological imaging plays a crucial role in the diagnosis of hepatocellular carcinoma (HCC) as the noninvasive diagnosis of HCC in high-risk patients by typical imaging findings alone is widely adopt...
To evaluate the impact of the level of inherent hepatic iron deposition on the ability of multiecho T2*-weighted magnetic resonance imaging (T2*WI) to identify hepatocellular carcinoma. This is releva...
To assess the ability of high-resolution arterial phase imaging of hepatocellular carcinoma (HCC) to provide combined vascular characterization and parenchymal evaluation.
The purpose of this study is to evaluate 3 imaging techniques and their associations : MRI, CTscanner and enhanced contrast ultrasound for the diagnosis of small (< 3 cm) hepatocellular ca...
Ethanol injection has been for many years the standard approach as percutaneous treatment of non-surgical early hepatocellular carcinoma in cirrhotic patients. Radiofrequency ablation has ...
To diagnose hepatocellular carcinoma (HCC) and to determine the extent of the disease, a triphasic CT scan or a magnetic resonance imaging are required. The characterization of hepatic nod...
This is a Phase I study, which means that the goal is to see if the combination of Temsirolimus and Sorafenib is safe in patients with Hepatocellular Carcinoma. Sorafenib is a standard tre...
Estimation of functional liver reserve in patients with hepatocellular carcinoma (HCC) in cirrhosis is of paramount importance to properly select candidates for surgical resection. Togethe...
Visualization of the heart structure and cardiac blood flow for diagnostic evaluation or to guide cardiac procedures via techniques including ENDOSCOPY (cardiac endoscopy, sometimes refered to as cardioscopy), RADIONUCLIDE IMAGING; MAGNETIC RESONANCE IMAGING; TOMOGRAPHY; or ULTRASONOGRAPHY.
Optical imaging techniques used for recording patterns of electrical activity in tissues by monitoring transmembrane potentials via FLUORESCENCE imaging with voltage-sensitive fluorescent dyes.
The use of molecularly targeted imaging probes to localize and/or monitor biochemical and cellular processes via various imaging modalities that include RADIONUCLIDE IMAGING; ULTRASONOGRAPHY; MAGNETIC RESONANCE IMAGING; fluorescence imaging; and MICROSCOPY.
Non-invasive imaging methods based on the mechanical response of an object to a vibrational or impulsive force. It is used for determining the viscoelastic properties of tissue, and thereby differentiating soft from hard inclusions in tissue such as microcalcifications, and some cancer lesions. Most techniques use ultrasound to create the images - eliciting the response with an ultrasonic radiation force and/or recording displacements of the tissue by Doppler ultrasonography.
Timing the acquisition of imaging data to specific points in the cardiac cycle to minimize image blurring and other motion artifacts.
Biological therapy involves the use of living organisms, substances derived from living organisms, or laboratory-produced versions of such substances to treat disease. Some biological therapies for cancer use vaccines or bacteria to stimulate the body&rs...
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
