Hypogonadism is a condition characterized by the body's inability to produce normal amounts of sex hormones, leading to various health issues like infertility, reduced libido, and osteoporosis. It can be caused by genetic factors, injury, or diseases affecting the hypothalamus, pituitary gland, or gonads, and is often treated with hormone replacement therapy.
Pulse sequences are a series of radiofrequency pulses and gradients used in MRI to manipulate the net magnetization of hydrogen nuclei, allowing for the generation of specific image contrasts. They are crucial for determining the type of information obtained from the MRI scan, such as T1-weighted, T2-weighted, or diffusion-weighted images.
