For instance, patient cases with abnormally low mitochondrial adenosine triphosphate (ATP) production have been characterized using a multiparametric sequence interleaving 1H imaging and spectroscopy with 31P MRS,73 with mitochondrial diabetes clearly distinguished from peripheral arterial disease by the normal perfusion and myoglobin (Mb) resaturation profiles (Figure 3). Here, MB is linked to peripheral arterial disease.
