Characterization of focal hepatic masses by dynamic contrast-enhanced MR imaging: Findings in 311 lesions

ENETS Consensus Guidelines for the Standards of Care in Neuroendocrine Tumors: Radiological Examinations

“…In the haemangioma the contrast enhancement will subsequently gradually extend towards the lesion center, and during the late contrast-enhancement phase a complete filling of the haemangioma is regularly seen. The haemangioma will then appear hyperintense compared to the normal liver whereas the washout of the CM from a liver metastasis regularly will make the lesion appear relatively hypointense [26]. Danet et al [27], who evaluated MR imaging findings on 512 metastatic lesions in 165 patients with NETs, reported that ring enhancement was observed in 72% of patients during the hepatic arterial dominant phase.…”

Acoustic radiation force impulse elastography in distinguishing hepatic haemangiomata from metastases: preliminary observations

“…MR accuracy [10] is higher than that for multiphase CT [11]. CT has a sensitivity of 75% with a specificity of 95% for haemangiomata [11].…”

Pediatric hepatic vascular anomalies

“…Optimal use of imaging modalities includes performing US studies with color Doppler and Doppler spectral analysis, abdominal CT with and without IV contrast medium and MRI with TI-weighted (T1W) sequences with and without gadolinium and fat suppression, T2W and gradient-recalled echo sequences or MRA [2,3]. As with CT, dynamic acquisition after contrast-medium administration has been shown to be useful in distinguishing between some of the hepatic tumors [4]. Angiography is used not only as a tool for endovascular therapy, but to provide precise anatomical information about these lesions.…”
