A Greater Help for Radiologists to Visualize Body Organs by MR-GILD
Magnetic Resonance Gated Intracranial cerebrospinal fluid (CSF) Dynamics (MR-GILD) technique is a magnetic resonance (MR) sequence. It is based on bipolar gradient pulse to show pulsatile flow in ventricles, cisterns, aqueduct of Sylvius and entire intracranial CSF pathway. This method is used to analyze CSF circulatory system dynamics in patients with CSF obstructive lesions like normal pressure hydrocephalus.
The magnetic resonance imaging (MRI) or nuclear magnetic resonance imaging (NMRI) is primarily used in radiology to visualize details of internal structure and limited functions of the body. This technique provides much greater contrast between the different soft tissues of the body that is difficult to find by computed tomography (CT) dose. It uses ionizing radiation and the powerful magnetic field aligns the nuclear magnetization of hydrogen atoms in water in the body. The signals produced by radio frequency can be manipulated by additional magnetic fields to build up enough information to construct images of the body organs.
There are several MRI specialized scans that provide clear pictures to the physicians. These MRI scan techniques are such as- Diffusion MRI, Magnetization transfer MRI, Fluid Attenuated Inversion Recovery (FLAIR), Magnetic resonance angiography (MRA), Magnetic resonance gated intracranial cerebrospinal fluid (CSF) or liquor dynamics (MR-GILD), Magnetic resonance spectroscopy (MRS), Functional MRI, Interventional MRI, Current density imaging (CDI), Susceptibility weighted imaging (SWI), etc. The Magnetic resonance gated intracranial cerebrospinal fluid (CSF) or liquor dynamics (MR-GILD) method allows physicians to visualize both arteries and venous pulsatile blood flow in vessels without using any contrast agents.
