Rapid in Vivo Adc Mapping of Hyperpolarized C Metabolites on a Clinical 3t Mr Scanner
Introduction: Apparent diffusion coefficient (ADC) maps of water have become useful for prostate cancer identification and characterization. Differences in local water mobility create contrast in these images, which in turn give an indication of the local tissue microstructure. The growing field of hyperpolarized C has also proven to be useful in identifying tumors by measuring the real-time me...

متن کاملHyperpolarized C-13
Where tanh is the hyperbolic tangens function, h the Planck constant, BBo is the main magnetic field strength, kBB the Boltzmann constant and T is the temperature. At a magnetic field of 1.5 T the polarization of the protons (H) at body temperature is only ∼5 x 10 and for C ∼1.0 x 10. The polarization is proportional to the magnetic field strength. Consequently, a 3 T scanner will result in a d...
متن کاملHyperpolarized (13)C MR Angiography.
Magnetic resonance angiography (MRA) is a non-invasive technology that can be used for diagnosis and monitoring of cardiovascular disease; the number one cause of mortality worldwide. Hyperpolarized imaging agents provide signal enhancement of more than 10, 000 times, which implies large reduction in acquisition time and improved spatial resolution. We review the role of hyperpolarized 13C agen...
متن کاملApparent diffusion coefficient of normal adrenal glands*
OBJECTIVE To assess the feasibility and reliability of apparent diffusion coefficient (ADC) measurements of normal adrenal glands. MATERIALS AND METHODS This was a retrospective study involving 32 healthy subjects, divided into two groups: prepubertal (PreP, n = 12), aged from 2 months to 12.5 years (4 males; 8 females); and postpubertal (PostP, n = 20), aged from 11.9 to 61 years (5 males; 1...
