Title
MRI of the Brain Without and With Intravenous Contrast
Clinical History
Patient-specific — populated from user input at report time. Shows "None" if not provided.
Comparison
No prior studies available for comparison.
Technique
Multiplanar multi-sequential MR imaging of the brain was performed. Non-contrast sequences include axial T1-weighted, T2-weighted, FLAIR, GRE, and DWI images; coronal FLAIR images; and sagittal T1-weighted images. ADC maps were calculated. Following intravenous gadolinium contrast administration, axial, coronal, and sagittal T1-weighted images were obtained.
Findings
Detailed examination of intracranial structures reveals normal findings throughout.
Ventricular System and Sulci:
The ventricles and sulci are normal for patient's stated age.
Diffusion-Weighted Imaging and Acute Infarction:
The diffusion-weighted images and ADC maps show no evidence of acute infarction or restricted diffusion.
Hemorrhage and Susceptibility:
The GRE/T2* images show no evidence of parenchymal hemorrhage or abnormal susceptibility artifact.
Mass Effect and Midline Structures:
There is no evidence of extra-axial collections, space-occupying mass lesion, mass-effect or midline shift.
Corpus Callosum:
The sagittal images demonstrate well formed intact corpus callosum.
Posterior Fossa and Cerebellar Tonsils:
The cerebellar tonsils appear to terminate above the level of foramen magnum. The brainstem, posterior fossa and cervicomedullary junction appear preserved.
Sellar Region and Pituitary:
The sella turcica, pituitary gland, optic chiasm and suprasellar region appear within normal limits.
Cerebellopontine Angles:
There is no gross mass lesion in the cerebellopontine angles.
Orbital Soft Tissues and Nasopharynx:
The orbital soft tissues and visualized nasopharynx appear normal.
Paranasal Sinuses and Mastoid Air Cells:
There are no fluid levels seen within paranasal sinuses and mastoid air cells.
Skull Base, Calvarium, and Upper Cervical Spine:
There is no abnormal bone marrow signal within the skull base, calvarium, and visualized upper cervical spine.
Intracranial Vasculature:
Expected flow-voids are present within the visualized intracranial vessels at the skull base level and dural venous sinuses.
Impression
No evidence of acute infarction, intracranial hemorrhage, space-occupying mass lesion, or midline shift.
