Nitric oxide increases the signal intensity of the T1-weighted magnetic resonance image of blood.

چکیده
Human blood was infused through a gas permeable membrane to determine if treatment with nitric oxide affects the signal intensity of its T1-weighted magnetic resonance image. Equal volumes of blood with increasing concentrations of methemoglobin were placed in glass tubes. T1-weighted images of the samples were obtained with a 1.5T magnetic resonance scanner. There was a linear correlation between the signal intensity of the T1-weighted images and the amount of methemoglobin in each sample (r2 = 0.94, p = 0.0015). Thus, blood that has been treated with nitric oxide can potentially be used as an autologous intravascular contrast agent for magnetic resonance imaging.

متن کاملNon-uniformity of Clinical Head, Head and Neck, and Body Coils in Magnetic Resonance Imaging (MRI)
Introduction Signal intensity uniformity in a magnetic resonance (MR) image indicates how well the MR imaging (MRI) system represents an object. One of the major sources of image non-uniformity in high-field MRI scanners is inhomogeneity of radio-frequency coil. The aim of this study was to investigate non-uniformity in head, head and neck, and body coils and compare the obtained results to det...
