"T1: moderately hypointense"
"T2: mildly to moderately hyperintense"
"T1 C+ (Gd): enhancement may be lesional or perilesional (enhancement outside the confines of the T1 delineated lesion) 7"
"T1 C+ (Eovist/Primovist):"
"DWI/ADC b600-800: restricted diffusion with ADC values lower than those of the surrounding parenchyma18"
"DWI/ADC b600-800: restricted diffusion with ADC values lower than those of the surrounding parenchyma18"
"number, size and location (using the Couinaud classification) of tumour(s)"
"Routine greyscale ultrasound, contrast-enhanced ultrasound, and intra-operative ultrasound all have roles to play."
"Some primaries have a tendency to produce hyper-enhancing metastases, including renal cell carcinoma, thyroid carcinoma, neuroendocrine tumours, etc. (see hypervascular liver lesions)."
"multiple hepatic cysts: no enhancement or mural nodules; can be hyper-dense/intense due to blood or infection"
"Eovist/Primovist is often useful for detection and confirmation of metastatic disease"
"hepatocellular carcinoma (HCC): hypervascular, more often solitary, possible hypoechoic US halo, cirrhotic liver, vascular invasion"
"cystic, calcified, infiltrative and echogenic appearances are all possible: see liver metastases ultrasound appearances"
"number, size and location (using the Couinaud classification) of tumour(s)"
"Liver metastases are typically hypoattenuating on unenhanced CT, enhancing less than surrounding liver following contrast 1. If there is concomitant hepatic steatosis, then the lesions may be iso- or even slightly hyperattenuating. Enhancement is typically peripheral, and although there may be central filling in on portal venous phase, the delayed phase will show washout; helpful in distinguishing a metastasis from a haemangioma 1."
"larger lesions (>1.5 cm) tend to show transient rim enhancement (i.e. with washout); helpful feature in distinguishing a metastasis from a liver haemangioma"
"multiple hepatic cysts: no enhancement or mural nodules; can be hyper-dense/intense due to blood or infection"
"multifocal fatty infiltration/focal fatty sparing: periligamentous, perivascular distribution; MRI in-out phase signal changes, vessels course through "lesions"; no mass effect"
