In-vitro
experiments
of hyperpolarized
13
C
substrates is a valuable tool to study normal and
pathogenic metabolic processes. Commonly these
experiments are performed in cell suspensions containing
between 25 100 million cells. We developed a low
volume, low number of cells setup. Using two prostate
cancer cell lines we show that accurate quantification
of metabolic conversion and perfect resolution (< 1Hz
linewidth) can be obtained with as little as two million
cells. Our setup expands the use of hyperpolarized MR
beyond immortalized cell lines, such as primary cell
cultures, for which high number of cells cannot be
obtained.
