Gd-eob-dtpa Enhanced Mr Imaging: Evaluation of Enhancement Effects and Enhancement Patterns in Hepatic Hemangioma
Purpose: To assess quantitatively and qualitatively the enhancement effects and the enhancement patterns of hepatic hemangioma and normal liver tissue on contrast-enhanced MR imaging (CE-MRI) obtained with gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA). Methods and Materials: A total of 22 patients with 32 hepatic hemangiomas (high flow type=23, low flow type=9) in no...
متن کاملGd-DTPA-enhanced MR imaging of cochlear schwannoma.
The majority of eighth cranial nerve tumors are acoustic schwannomas, with greater than 90% arising from the vestibular division within the internal auditory canal. Most originate near the porus acusticus at the gliai-Schwann cell interface. The minority of vestibular schwannomas arise at other locations along the nerve, such as within the vestibule or at the fundus of the internal auditory can...
متن کاملGd-DTPA-enhanced MR of suspected spinal multiple sclerosis.
A prospective study was undertaken to evaluate the potential of Gd-DTPA-enhanced MR to differentiate active from inactive demyelinating lesions of the cervical spinal cord. Five patients with elongated high-signal-intensity lesions in the cervical cord on long TR/TE spin-echo MR images and a clinical suspicion of demyelinating disease had MR before and after IV Gd-DTPA. Delayed contrast enhance...
متن کاملGd-DTPA-enhanced MR of multiple cryptococcal brain abscesses.
A 39-year-old man with insulin-dependent diabetes presented to the emergency room with headaches, nausea, vomiting , and slight changes in mental status. CSF studies on admission showed elevated protein , normal glucose, and WBCs with a predominance of lymphocytes , consistent with chronic meningitis . Chest radiograph was normal, and a CT scan was obtained (Fig. 1 A). Repeat CSF studies again ...
متن کاملGd-DTPA-enhanced MR imaging of pituitary adenomas.
Eleven previously nonoperated patients with suspected pituitary microadenomas were scanned on a 1.5-T GE system before and after administration of IV gadolinium-DTPA (0.1 mmol/kg). Six patients had Cushing disease, four had hyperprolactinemia, and one had acromegaly. Surgical confirmation was available in all cases, and these findings were correlated with results of CT and venous sampling, when...
