How do you contour the hippocampus?
A Step-by-Step Guide to Contouring the Hippocampus
- Step 1: Find the Slice With a Good View of the Temporal Horn.
- Step 2: Contour Inferiorly From the Level of the Temporal Horn.
- Step 3: Contour Superiorly From the Level of the Temporal Horn.
What is the function of the hippocampus?
Hippocampus is a complex brain structure embedded deep into temporal lobe. It has a major role in learning and memory. It is a plastic and vulnerable structure that gets damaged by a variety of stimuli. Studies have shown that it also gets affected in a variety of neurological and psychiatric disorders.
What is hippocampal sparing?
Hippocampal-sparing was defined as a mean dose to at least one hippocampus of less than 30 Gy. The dose delivered to the tumour was never compromised to achieve the hippocampal dose constraint. Logistic regression analyses were performed to identify predictive factors for achieving hippocampal-sparing treatment.
What procedures do radiation oncologists perform?
Radiation oncologists use a variety of treatment methods, including radioactive implantations, external beam radiotherapy, hyperthermia and combined modality therapy such as radiotherapy with surgery, chemotherapy or immunotherapy.
What is temporal horn?
The temporal horn of the lateral ventricle (inferior horn, descending horn; middle horn; medicornu), is the largest of the horns of the lateral ventricle, traverses the temporal lobe of the brain, forming in its course a curve around the posterior end of the thalamus. …
What is the right hippocampus responsible for?
The hippocampus helps humans process and retrieve two kinds of memory, declarative memories and spatial relationships. Spatial relationship memories appear to be stored in the right hippocampus. The hippocampus is also where short-term memories are turned into long-term memories.
Where is the hippocampus located and what is its function?
Hippocampus is a brain structure embedded deep in the temporal lobe of each cerebral cortex. It is an important part of the limbic system, a cortical region that regulates motivation, emotion, learning, and memory.
What do radiology oncologists do?
A radiation oncologist uses ionizing radiation and other modalities to treat malignant and some benign diseases. Radiation oncologists also may use computed tomography (CT) scans, magnetic resonance imaging (MRI), ultrasound, and hyperthermia (heat) as additional interventions to aid in treatment planning and delivery.
What are the responsibilities of a radiation oncologist?
The radiation oncologist is responsible for determining the role of radiation therapy in a patient’s care, planning the treatment, and evaluating the patient for the response to the treatment.
What causes atrophy of the hippocampus?
While hippocampal atrophy is a key feature of both hippocampal sclerosis (HS) and Alzheimer’s disease (AD), the pathology underlying this finding differs in these two conditions. In AD, atrophy is due primarily to loss of neurons and neuronal volume as a result of neurofibrillary tangle formation.
