Technology & Expertise

Medical Metrics® (MMI) utilizes industry leading software solutions to accomplish multimodality image review and advanced quantitative analysis for clinical trials. These validated software packages are vendor independent, DICOM compliant, and, when integrated into MMI’s HIPAA- and 21 CFR Part 11-compliant data management system, create a seamless system for image management, analysis, and delivery of results.

MMI provides independent image analysis for an array of cardiovascular imaging modalities. Because our physicians practice within a high-volume clinical environment and are active investigators in a wide array of clinical trials and research studies, they are experienced in the analysis of both novel and SoC imaging modalities. Our physicians have expertise in the following imaging modalities:


  • Systolic/Diastolic myocardial function myocardial function
  • Valvular function (stenosis/regurgitation)
  • Chamber characteristics (hypertrophy/enlargement)
  • Extracardiac abnormalities (pericardial/aortic)

Vascular Ultrasound

  • Atherosclerotic burden
  • Vessel dimensions and/or stenosis
  • Stent and graft patency
  • Carotid Intima Thickness (IMT)

Invasive Angiography

  • Minimum lumen diameter
  • Reference vessel diameter
  • Percent diameter stenosis
  • Stenosis length
  • Pressure gradient across stenosis

Cardiac Computed Tomography

  • Cardiac anatomy and function
  • Aortic and peripheral visualization
  • Coronary atherosclerotic burden (calcified/non-calcified plaque)

Magnetic Resonance Angiography

  • Arterial stenosis
  • Venous diseases
  • Assessment of novel contrast agents
  • Assessment of atheroma volume and atheroma characteristics

Cardiac Magnetic Resonance Imaging

  • Ventricular mass, volume, and function
  • Myocardial viability and scar imaging
  • Myocardial perfusion imaging
  • Quantification of valvular regurgitation

Nuclear Imaging

  • Regional myocardial perfusion (ischemia/infarct)
  • Systolic myocardial function (ejection fraction)
  • Myocardial viability

Transcranial Doppler

  • Flow analysis for carotid intervention
  • Confirmation of patent foramen ovale (PFO) closure
  • Quantitative analysis of emboli during cardiovascular procedures

Optical Coherence Tomography

  • Adequacy of stent strut apposition
  • Edge dissection
  • Stent endothelization versus restenosis
  • Plaque fibrous capsule thickness

Intravascular Ultrasound (IVUS)

  • Atherosclerosis location, severity, and composition
  • Degree and location of neointima hyperplasia
  • Arterial remodeling
  • Stent deployment/apposition
