MR imaging of liver neoplasms

Surface-coil MR imaging of orbital neoplasms.

Fifteen patients with orbital neoplasms demonstrated by CT were studied with magnetic resonance (MR) using a 13 cm surface coil and a 0.6 T superconducting magnet. The use of a surface coil allowed for a reduction in slice thickness and a significant improvement in spatial resolution resulting in better demonstration and improved characterization of orbital lesions. All neoplasms (15/15) were d...

MR imaging of primary trochlear nerve neoplasms.

We present the clinical, anatomic, and MR imaging findings in six patients with seven primary trochlear nerve neoplasms, as well as the MR and clinical criteria that serve to establish the diagnosis of these rare cranial nerve neoplasms. Three patients had a history of neurofibromatosis and five patients had clinical evidence of a trochlear nerve palsy. Six of seven neoplasms produced localized...

MR imaging of hemorrhagic intracranial neoplasms.

Thirty patients with intracranial tumors containing hemorrhage of varying stages were examined with high-field-strength MR imaging and CT to determine what differences might exist between hemorrhagic tumor and pure hemorrhage. Pathology was obtained in the six patients with primary tumors and in 14 of the 24 patients with metastases. Similar to evolving intraparenchymal hematomas, hemorrhagic n...

Mr Imaging of the Liver Ii: Diseases

Hepatocellular carcinoma (HCC) is the most common primary cancer of the liver. The overall 5-year survival rate without any treatment is less than 5%.9 HCC is less frequent in Western countries than in the East or Southeast Asia. The incidence of HCC, however, is rising in Europe and North America.9, 38 In a recent study, the incidence of HCC in the United States increased from 1.4 per 100,000 ...
