  • 3T Siemens Prisma
  • 3T General Electric Discovery
  • 1.5T General Electric Signa
  • General Electric Light Speed 16-slice CT
  • General Electric LOGIQ E10 Ultrasound

Core Services:

These are the most common services we provide our users, which can be adapted to meet the needs of various studies.

MRI and MRS:

  • MRS of muscle, liver, marrow and adipose tissue with analyses for lipid profiling
  • Magnetic resonance elastography (MRE) for assessment of liver fibrosis
  • Quantification of areal and volumetric visceral and subcutaneous adipose tissue
  • Liver MRI for assessment of steatosis and fibrosis (using Perspectum Multiscan protocol)
  • Brain MRI
  • Additional custom MRI protocols available for NORCH-related research


  • QCT - helical using single- or dual-energy CT for volumetric acquisition of bone mineral density
  • QCT single-slice for quantification of visceral and subcutaneous fat, cross-sectional muscle area
  • CT analysis for body composition performed with deep learning algorithm (ideal for medium or large-scale studies or datasets requiring short-term execution)


  • Quantitative ultrasound 
  • Shear wave elastography (SWE) for assessment of liver fibrosis and steatosis

Positron emission tomography (PET) :

  • PET*
  • PET/CT*
  • PET/MRI*

* Services offered through MGH Gordon PET Core.

Individual consultation and training services:

  • Imaging analysis, including quantitative interpretation of imaging data
  • Image/Data Transfers
  • H-MRS for lipid profiling (intramyocellular lipid, intrahepatic lipid, marrow fat)
  • Help with study design and methods to include available Core techniques in human research studies.
  • Tutorials and workshops in imaging techniques used in metabolic investigation
