The image shows an axial section of a T2 brain MRI scan, at the level of the lateral ventricles, with the frontal, temporal and occipital lobes visible. On a T2 MRI scan, the grey matter is white, the white matter is darker, and the fluid is white. The blue arrow indicates the occipital horn of the lateral ventricle on the right side, because the occipital cortex can be identified either side of the median interhemispheric fissure separating the two cerebral hemispheres. It can also be identified because it is found at the level of the diencephalon which lies anterior to the occipital horns and inferior to the body of the lateral ventricles.

Occipital horn of the lateral ventricle
QuestionChoice
The image shows an axial section of a T2 brain MRI scan, at the level of the lateral ventricles, with the frontal, temporal and occipital lobes visible. On a T2 MRI scan, the grey matter is white, the white matter is darker, and the fluid is white. The frontal horns of the lateral ventricles are found in the depths of the frontal lobes, which are located in the superior aspect of the image. However, the blue arrow indicates the occipital horn of the lateral ventricle on the right side, because the occipital cortex can be identified either side of the median interhemispheric fissure separating the two cerebral hemispheres. It can also be identified because it is found at the level of the diencephalon which lies anterior to the occipital horns and inferior to the body of the lateral ventricles.

c
Frontal horn of the lateral ventricle
QuestionChoice
The image shows an axial section of a T2 brain MRI scan, at the level of the lateral ventricles, with the frontal, temporal and occipital lobes visible. On a T2 MRI scan, the grey matter is white, the white matter is darker, and the fluid is white. The temporal horns of the lateral ventricles are found in the depth of the temporal lobes – these are not visible at this level of the MRI scan, they are located more inferiorly.  However, the blue arrow indicates the occipital horn of the lateral ventricle on the right side, because the occipital cortex can be identified either side of the median interhemispheric fissure separating the two cerebral hemispheres. It can also be identified because it is found at the level of the diencephalon which lies anterior to the occipital horns and inferior to the body of the lateral ventricles.

b
Temporal horn of the lateral ventricle
QuestionChoice
The image shows an axial section of a T2 brain MRI scan, at the level of the lateral ventricles, with the frontal, temporal and occipital lobes visible. On a T2 MRI scan, the grey matter is white, the white matter is darker, and the fluid is white. The third ventricle is found in the midline of the brain, at the level of the diencephalon, in between the two thalami. It is found at a more inferior level compared to the one MRI scan shown. However, the blue arrow indicates the occipital horn of the lateral ventricle on the right side, because the occipital cortex can be identified either side of the median interhemispheric fissure separating the two cerebral hemispheres. It can also be identified because it is found at the level of the diencephalon which lies anterior to the occipital horns and inferior to the body of the lateral ventricles.

e
Third ventricle
QuestionChoice
The image shows an axial section of a T2 brain MRI scan, at the level of the lateral ventricles, with the frontal, temporal and occipital lobes visible. On a T2 MRI scan, the grey matter is white, the white matter is darker, and the fluid is white. The body of the lateral ventricle is found at a superior level compared to that of the MRI scan shown, superior to the diencephalon structures, connecting the frontal and the occipital horns. However, the blue arrow indicates the occipital horn of the lateral ventricle on the right side, because the occipital cortex can be identified either side of the median interhemispheric fissure separating the two cerebral hemispheres. It can also be identified because it is found at the level of the diencephalon which lies anterior to the occipital horns and inferior to the body of the lateral ventricles.
