Educational Objective
The purpose of this presentation is to familiarize the audience with the anatomy and physiology of  the liver, describe some of the common diseases of the liver, and how it all directs the way we image the liver. Included in the presentation will be contrast media focused on Gadolinium-based  MRI contrast agents.


  1. Liver anatomy and physiology
    1. Location, size, shape
    2. Blood supplies
    3. Venous drainage
    4. Lymph drainage
    5. Cellular level anatomy and physiology
  2. Use of T1W and T2W images
  3. Role of diffusion in liver imaging
    1. Cancer
    2. Infection
  4. Why contrast enhanced liver exam?
    1. Carcinomas
    2. Metastasis
    3. Infections
    4. Other cancer
  5. Timing of post-contrast imaging
    1. Early arterial, late arterial, venous, hepatobiliary
    2. Techniques for specific timing
      1. Guessing!
      2. TestBolus
      3. CareBolus
      4. TwistVIBE
  6. Use of hepatocyte-specific agents (HSA) and non….
    1. What is this?
      1. Multihance/Eovist
    2. How does it change the outcome
    3. Why one or the other?
      1. Hepatocytes or extracellular areas of interest?
      2. Hepatobiliary timing
      3. Opportunity for CE MRCP post-HAS
  7. Motion suppression techniques
    1. Breath-hold
    2. Trigger/gate
    4. SSTSE and SSFP GRE (TrueFISP)

About the American Registry of
Magnetic Resonance Imaging Technologists

Because MRI is a Specialty

The mission of the American Registry of Magnetic Resonance Imaging Technologists (ARMRIT) is to recognize individuals qualified as specialists and to promote high standards of patient care and safety in the diagnostic medical imaging modality of Magnetic Resonance Imaging (MRI) technology including: interventional MRI, cardiovascular MRI, functional MRI, and MRI breast imaging.

ARMRIT is the first certifying organization to:
1.    Recognize MRI technology as a distinct medical imaging specialty utilizing non-ionizing radiation.
2.    Require MRI clinical experience and competency for eligibility.
3.    Promote formal MRI education with MRI clinical training.
4.    Recognize MRI schools that offer full-time educational program leading to a career in MRI.

Certification through the Registry is open to qualified technologists in all imaging fields who have documented MR clinical experience and/or formal education completed through schools dedicated to MRI technologists.
