Randomized Controlled Trial Comparative Study
Detection of cerebral metastases on magnetic resonance imaging: intraindividual comparison of gadobutrol with gadopentetate dimeglumine.
Contrast-enhanced magnetic resonance (MR) imaging with gadolinium-based contrast agents is widely used for the detection of cerebral metastases with standard contrast agents. Newer developments in MR contrast agents have led to a higher relaxivity and/or concentration for these agents. ⋯ At equal gadolinium dosage, gadobutrol appears to offer significant advantages over gadopentetate dimeglumine for the visualization of brain metastases, with particular benefit for improving the conspicuity of detected lesions.

Uterine endometrial cancer is the most common gynecologic malignancy, and benign endometrial hyperplasia or polyps should be differentiated from endometrial cancer. In evaluating endometrial cancer on magnetic resonance imaging (MRI), the assessment of the depth of myometrial invasion is important because it closely correlates with the patient's prognosis. ⋯ DWI provides helpful information in evaluating benign and malignant endometrial lesions.
