2024年7月6日 · The lateral ventricles are paired CSF-filled spaces in the cerebrum and part of the ventricular system of the brain. They are larger than the third or fourth ventricles but can be …

2024年7月29日 · Ventricles contain around 20% of the total average adult CSF volume, around 20-25 mL. The ventricular system consists of four ventricles (spaces), two being midline and …

2024年10月13日 · The lateral ventricles occasionally show small side to side differences in size on CT or MRI of the brain. This asymmetry of the lateral ventricles (ALV) is an anatomic …

2024年10月18日 · The ventricle is focally expanded. Any part of the ventricle proximal to it (e.g. the temporal horn of the lateral ventricle in lesions of trigone) may be dilated due to outflow …

2022年3月24日 · Trapped ventricle, also known as isolated ventricle, is a condition in which there is an obstruction to the entry and exit path of CSF through the ventricle.

2024年8月22日 · A typical MRI protocol would include three plane imaging (essential if the relationship of the mass to the ventricle is to be confidently determined) and post-contrast …

2025年2月7日 · Subependymal grey matter heterotopia, also known as periventricular heterotopia, is the most common form of grey matter heterotopia and is characterized by …

2024年10月3日 · Subependymomas are most commonly seen in the fourth ventricle, but can arise anywhere where there is ependyma. They are therefore in the differential for other …

2024年5月21日 · The anteroposterior diameter of the lateral ventricle index (ALVI) is a quantitative metric to evaluate the size of the lateral ventricles, particularly in normal pressure …

2025年2月12日 · The white matter tracts which usually cross the midline, instead are oriented vertically, separating the lateral ventricles widely, in a racing car sign configuration. These …
