The prevalence of DIE is estimated to be 1 to 2% in women of reproductive age. Deep endometriosis typically presents as a single nodule in the vesicouterine fold or in the lower 20 cm of the bowel. Deep endometriosis can be associated with severe pain. However, it can be present without severe levels of pain. [99]
In vivo magnetic resonance spectroscopy (MRS) is a specialized technique associated with magnetic resonance imaging (MRI). [1] [2]Magnetic resonance spectroscopy (MRS), also known as nuclear magnetic resonance (NMR) spectroscopy, is a non-invasive, ionizing-radiation-free analytical technique that has been used to study metabolic changes in brain tumors, strokes, seizure disorders, Alzheimer's ...
Typically in MRS a single spectrum is acquired by averaging enough spectra over a long acquisition time. [8] Averaging is necessary because of the complex spectral structures and relatively low concentrations of many brain metabolites, which result in a low signal-to-noise ratio (SNR) in MRS of a living brain.
New research has found that endometriosis is linked to a four times higher risk of ovarian cancer, and deep infiltrating endometriosis is tied to a 10 times higher risk of this form of cancer.

Diffusion imaging is an MRI method that produces in vivo magnetic resonance images of biological tissues sensitized with the local characteristics of molecular diffusion, generally water (but other moieties can also be investigated using MR spectroscopic approaches). [15]
Endometriosis is a condition where cells similar to the womb lining grow elsewhere in the body, causing inflammation, pain, and scar tissue. ... rarely, the brain. The most common symptom is pain ...
The first study of the human brain at 3.0 T was published in 1994, [13] and in 1998 at 8 T. [14] Studies of the human brain have been performed at 9.4 T (2006) [15] and up to 10.5 T (2019). [16] Paul Lauterbur and Sir Peter Mansfield were awarded the 2003 Nobel Prize in Physiology or Medicine for their discoveries concerning MRI.
