  1. Repetition Time
    • According to 3 sources
    TR (Repetition Time) in Magnetic Resonance Imaging (MRI) is the time interval between successive pulse sequences applied to the same slice. Specifically, TR is the duration between the application of one RF (radiofrequency) pulse and the next.

    The repetition time (TR) is the time from the application of an excitation pulse to the application of the next pulse. It determines how much longitudinal magnetization recovers between each pulse. It is measured in milliseconds.

    What is tr in MRI?
    Specifically, TR is the duration between the application of one RF (radiofrequency) pulse and the next. Measured in milliseconds (ms), TR primarily governs the extent of longitudinal relaxation (T1 relaxation) before the subsequent pulse, making it a vital parameter that significantly influences image contrast and signal characteristics in MRI.

    How is an MRI performed?

    During an MRI (Magnetic Resonance Imaging) procedure, you lie on a table that slides into a large tube-shaped machine. This machine generates a strong magnetic field and uses radio waves to create detailed images of your body's internal structures. It is a non-invasive and painless procedure, but you need to remain still throughout the scan. In some cases, a contrast dye may be administered through an IV to enhance the imaging. The entire process is closely monitored by a trained technologist or radiologist to ensure safety and image quality.

    What physics underlying TR and Te in MRI?
    The physics underlying TR and TE in MRI involves the interaction between the magnetic field, the RF pulses, and the hydrogen nuclei (protons) in the body. Here’s a detailed breakdown: Main Magnetic Field (B0): When a patient is placed in the MRI scanner, they are exposed to a strong static magnetic field (B0).

    What is tr in RF imaging?
    TR is the time interval between two successive RF pulses. It is determined by the characteristics of the tissue being imaged and the desired image contrast. Longer TR values can improve the signal-to-noise ratio (SNR), as more time is allowed for the relaxation of spins between excitation pulses, resulting in a stronger signal.

    What is MRI based on?
    MRI is based on the magnetization properties of atomic nuclei. A powerful, uniform, external magnetic field is employed to align the protons that are normally randomly oriented within the water nuclei of the tissue being examined.

    What is Te in MRI?
    TE refers to the time between the excitation pulse and the peak of the MRI signal generated by the hydrogen atoms in the body. After the RF excitation pulse is applied, the hydrogen atoms in the body produce a detectable signal that decays over time due to various factors such as T1 and T2 relaxation times.
