Intermolecular zero-quantum coherence imaging of the human brain

Intermolecular Double-Quantum-Coherence Imaging

Introduction Recently we have demonstrated a new type of MRI based on detection of intermolecular zero-quantum coherences (iZQCs) both in vitro and in viva.‘,’ These coherences correspond to simultaneously flipping two water spins in opposite directions on molecules separated by 10 pm 10 mm. It is also possible to detect intermolecular double quantum coherences (iDQCs) corresponding to simultan...

Efficient infrared imaging upconversion via quantum coherence

We show that quantum coherence can be used to achieve marked improvement in the efficiency of the process of infrared upconversion. In one particular example which we analyze in detail, we show that it is possible to convert infrared radiation at a wavelength of 100 mm to the visible with essentially 100% efficiency while maintaining diffraction-limited imaging of the infrared field. © 2000 Ame...

In Vivo Noninvasive Detection of Brown Adipose Tissue through Intermolecular Zero-Quantum MRI

The recent discovery of active Brown Adipose Tissue (BAT) in adult humans has opened new avenues for obesity research and treatment, as reduced BAT activity seem to be implicated in human energy imbalance, diabetes, and hypertension. However, clinical applications are currently limited by the lack of non-invasive tools for measuring mass and function of this tissue in humans. Here we present a ...

Iranian Brain Imaging Database: A Neuropsychiatric Database of Healthy Brain

Introduction: The Iranian Brain Imaging Database (IBID) was initiated in 2017, with 5 major goals: provide researchers easy access to a neuroimaging database, provide normative quantitative measures of the brain for clinical research purposes, study the aging profile of the brain, examine the association of brain structure and function, and join the ENIGMA consortium. Many prestigious databases...
