MRI determines the causes of hip pain that may originate from nearby structures, like the pubic bones, sacroiliac joints, or the lower lumbar spine(3). Several tendons insert around the hip and may become inflamed or degenerated. This tool can show changes in the cartilage and the underlying bone, helping doctors detect arthritis’ early signs(2). MRI is a medical imaging tool that evaluates various causes of pain surrounding the hip joint. How Does Hip MRI Work in Medical Diagnosis? This modality is considered safe, non-invasive, and depicts accurate anatomical details(1). This medical imaging method can detect stress fractures or bone bruises that a regular X-ray usually misses.Īccording to a study, MRI is the modality of choice when determining X-ray results’ abnormalities and the diagnosis of various hip conditions. Magnetic resonance imaging (MRI) utilizes magnet and radio waves to produce diagnostic images that allow a doctor to visualize the hips. This article presents a step-by-step guide to contouring the hippocampus on axial magnetic resonance images for radiation therapy treatment planning.This webpage presents the anatomical structures found on hip MRI.
The cranial-most extent of the hippocampus is at the level of the splenium of the corpus callosum. Step 3: Contour superiorly from the level of the temporal horn above the level of the temporal horn the hippocampus is the strip of gray matter bounded by cerebrospinal fluid in the lateral ventricle and ambient cistern. The caudal most portion of the hippocampus is at the level of the pons and pituitary gland. You have to guess where this boundary is by extrapolating from more superior slices.
Step 2: Contour inferiorly from the level of the temporal horn below the level of temporal horn there is no visible boundary between the hippocampus and amygdala. Step 1: Find the slice where the temporal horn-meaning the most anterior portion of the lateral ventricle-is well visualized the hippocampus is the gray matter inside the curve of the temporal horn. We explain how to contour the hippocampus on axial T1 echo sequence magnetic resonance images with intravenous gadolinium. The purpose of this article is to present a step-by-step guide to contouring the hippocampus on axial images as would be done in the standard process of planning conformal radiotherapy for brain radiotherapy. Limiting the dose to the hippocampus will likely decrease cognitive problems from brain radiotherapy.
