“…Since the early 1980s, numerous magnetic resonance (MR) techniques have been studied to determine the optimum imaging technique for the detection and characterization of hepatic lesions [1][2][3][4][5][6][7][8][9], but time constraints in routine clinical practice require the use of faster MR imaging methods [10 -11].…”

“…In contradistinction, other hepatic masses except for cysts show a relative decrease in signal intensity on more heavily T2-weighted images. However, on non-contrast-enhanced MRI, vascular metastases such as those from pheochromocytoma, carcinoid, and pancreatic islet cell tumors are occasionally indistinguishable from hemangioma because of their marked hyperintensity on T2-weighted images [35,36] . Dynamic gadolinium-enhanced MRI is helpful in making this differentiation [37–40] .…”

Distinguishing benign from malignant liver tumours

Liver masses are very common and most are benign. It is therefore important to avoid unnecessary interventions for benign lesions, while at the same time ensuring accurate diagnosis of hepatic malignancies. Many cancer patients, like the general population, have incidental benign liver lesions. In planning treatment for cancer patients, it is critical to avoid inappropriate treatment decisions based on misdiagnosis of a benign lesion as a metastasis or primary liver malignancy. This article describes the salient imaging features of the common benign liver masses and outlines a general approach to distinguishing between benign and malignant hepatic lesions.

Postcontrast images with a 0.1 mmol/kg dose of a gadolinium chelate with extracellular distribution, when acquired dynamically during breath holding, can improve both differential diagnosis and lesion recognition in liver MR imaging. Initial results at 0.3 mmol/kg, compared with 0.1 mmol/kg, suggest a substantial improvement in lesion identification at the high dose, as assessed by using signal intensity difference divided by noise. Of the gadolinium chelates with predominantly renal excretion, only gadoteridol is presently approved in the United States at the high dose, with limited clinical evaluation for liver imaging performed to date. For linear chelates, such as gadopentetate dimeglumine and gadodiamide injection, the degree to which release of free gadolinium ion occurs is a possible issue because of lower in vivo stability (42,43). Preliminary results with hepatobiliary gadolinium chelates and iron particulate agents are favorable with regard to efficacy, although these agents remain in clinical trials.
