Obesity is an ongoing public health problem that is difficult to treat. There is evidence that obesity has fetal origins. Body composition, including visceral, subcutaneous, brown, and hepatic fat have been found to be important predictors in obesity and metabolic syndrome. Magnetic resonance imaging (MRI) can quantify body composition that does not require radiation but is motion limited. The investigators have developed a motion-compensated MRI sequence, also known as "free breathing" MRI. In this study, the investigators plan to obtain free-breathing MRIs of pregnant women in the third trimester of pregnancy. MRIs will be obtained from healthy mothers, mothers with growth-restricted fetuses, and mothers with gestational diabetes. The different types of adipose tissue will be measured and compared between groups and correlated to birth growth parameters. The goal is this study is to assess if motion-compensated MRI can help predict early growth patterns in infancy.

Primary | Maternal Visceral Adipose Tissue Volume | MRI data will be reconstructed by Siemens scanner software to produce 3D fat-water separated images and PDFF maps. The FB-MRI radial data will be transferred to a separate workstation for custom reconstruction of 3D fat-water-separated images and PDFF maps and analysis. Visceral adipose tissue PDFF values will be directly measured from regions of interest. | During the procedure (MRI) | |
Primary | Fetal Liver PDFF | MRI data will be reconstructed by Siemens scanner software to produce 3D fat-water separated images. The distribution/extent of hepatic fat will be manually delineated/drawn on the 3D MRI images and PDFF maps. This work will be performed by PI Strobel with validation from PI Wu. | During the procedure (MRI) | |
Secondary | Fetal Subcutaneous Tissue Volume | MRI data will be reconstructed by Siemens scanner software to produce 3D fat-water separated images and PDFF maps. The FB-MRI radial data will be transferred to a separate workstation for custom reconstruction of 3D fat-water-separated images and PDFF maps and analysis. Subcutaneous adipose tissue PDFF values will be directly measured from regions of interest. | During the procedure (MRI) | |
Secondary | Maternal Subcutaneous Tissue Volume | MRI data will be reconstructed by Siemens scanner software to produce 3D fat-water separated images. The distribution/extent of subcutaneous fat will be manually delineated/drawn on the 3D MRI images and PDFF maps and used to calculate volume of subcutaneous adipose tissue. This work will be performed by PI Strobel with validation from PI Wu. | During the procedure (MRI) | |
Secondary | Maternal Hepatic Fat PDFF | MRI data will be reconstructed by Siemens scanner software to produce 3D fat-water separated images and PDFF maps. The FB-MRI radial data will be transferred to a separate workstation for custom reconstruction of 3D fat-water-separated images and PDFF maps and analysis. Hepatic adipose tissue PDFF values will be directly measured from regions of interest. | During the procedure (MRI) |
