Neuroimaging Techniques Review
Review the Neuro Imaging Techniques. In particular, since MRI has become such an important tool used in medicine review the tissue image characteristics as seen by T1 and T2 scans. Can you identify a T2 scan when you see one?
Left Ventricle Hydrocephalus: horizontal MRI This is an MRI of a patient with an obstruction of the left foramen of Monroe, causing left ventricular hydrocephalus. Compare the relative size of the left and right lateral ventricles.
MRI and MR Angiograpy This image contains an MR angiogram, which uses a pulse sequence to enhance blood flowing through vessels, and the corresponding T1 MRI. Can you identify the vessels and corresponding neuroanatomy?
Horizontal MRI of Low Brainstem This is a T1 weighted MRI at the level of the low brainstem. Can you identify the structures with the pointers? (from Harvard's Whole Brain Atlas)
Horizontal MRI of Mid Brainstem This is a T2 weighted MRI at the level of the upper brainstem. Can you identify the structures with the pointers? (from Harvard's Whole Brain Atlas)
This is a multiple slice tour of the Diencephalon as seen by T2 weighted MRI's. (adopted from Harvard's whole brain atlas) On the following sections identify the mamillary bodies, red nucleus, substantia nigra, pineal gland, pituitary gland, sphenoid sinus, infundibulum, suprasellar cistern, cerebral peduncle, hypothalamus, posterior commisure, thalamus and fornix.
Horizontal MRI This is a horizontal T2 weighted MRI at the level of the basal ganglia. Can you identify all ofthe structures with the pointers? (from Harvard's Whole Brain Atlas)
The Following are T1 Coronal MRI's.
The Following are T1 Sagittal MRI's.Can you tell me which is the most median and which is the most lateral?
