History of allergic asthma. 7 Suspected lesions or suffering from any of the following CNS diseases/lesion types as the main indication for MRI: • Meningeal disease (focal enhancement) • Pituitary adenomas (macro and micro) • Tumors of the choroid plexus • Tumors of the pineal gland • Dermoid/epidermoid tumors • Infectious disease (e.g. brain abscess, cisticercosis, etc.) • Venous angiomas • Subacute/chronic ischemia • Encephalitis • Multiple sclerosis (acute and chronic) • Optic neuritis • Chordomas • Von Hippel Lindau syndrome • Hypertensive leukoencephalopathy. 8. Receipt of any contrast agent <72 h prior to the study MRIs, or planned receipt of any contrast agent within 72 h after the second study MRI. 9 Planned or expected biopsy or any interventional therapeutic procedure from the first study MRI up to 24 h after the second study MRI. 10. Planned or expected change in any treatment or procedure between the two study MRIs that may alter image comparability and /or chemotherapy which is changed between the two MRI procedures.
11. Has been previously enrolled in this study.
12. Has received any investigational product within 30 days, or within 5 times half-life of the investigational product, whichever is shorter, prior to enrolling in this study. Note: Participants who have entered the follow-up period of or have been discontinued from an investigational study may participate as long as it has been 30 days after the last dose of the previous investigational product, or 5 times half-life of that investigational product, whichever is shorter.
13. Contraindications to the administration of gadobutrol (depending on local product label).
