PET/CT Study in the Diagnosis of Coronary Plaque (PET/CT)

This study has been completed.

Robert Gropler, Washington University School of Medicine Identifier:
First received: February 20, 2009
Last updated: May 2, 2014
Last verified: May 2014
This study is being done to determine if a picture taking test of the heart, positron emission tomography/computed tomography (or cardiac PET/CT), can identify the blockages in the heart arteries that lead to heart attacks when compared to the standard of heart catheterization.

Condition Intervention
Myocardial Infarction Coronary Artery Disease Cardiac Catheterization Radiation: Positron Emission Tomography Radiation: 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose Radiation: Computed Tomography Drug: CT Contrast Dye

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: x Comparison of Cardiac Positron Emission Tomography/Computed Tomography (PET/CT) With Coronary Angiography (CA) in the Diagnosis and Characterization of Coronary Artery Plaque

Further study details as provided by Robert Gropler, Washington University School of Medicine:

Primary Outcome Measures:
  • To determine if a combined non-invasive cardiac imaging test (PET/CT) can determine coronary plaque severity, morphology and metabolic activity when compared to the gold standard of coronary angiography and intravascular ultrasound. [ Time Frame: 1.5 years ]

Enrollment: 3
Study Start Date: October 2007
Study Completion Date: September 2009
Primary Completion Date: September 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: PET/CT
If enrolled in this study, the participant will have a PET/CT along with their Cardiac Catheterization to compare usability of images in diagnosis of heart vessel disease.

Radiation: 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose
maximum of 10mCi of 18F-FDG will be injected for imaging purposes
Other Name: 18F- FDG
Radiation: Computed Tomography
image scan
Other Name: CT.
Drug: CT Contrast Dye
used for obtaining images. weight based dose
Other Name: CT contrast

Detailed Description:

Heart catheterization, in which a thin plastic tube, or catheter, is placed into an artery in the arm or leg and advanced into the heart arteries, is the procedure that you and your doctor have decided to pursue to look for heart artery blockages. It is being performed as part of your standard care and not for research purposes. The research procedure (cardiac PET/CT), which will be performed at a later date is a combination of heart CT (a test that involves the use of x-rays to identify heart artery blockages) and heart PET (an imaging test that uses a radioactive drug to look at how the heart uses fuel (sugar and fats) These tests will be combined (PET/CT) to look for the presence and type of blockage in your heart arteries.

It is important to develop a test that can determine if and what type of blockage you have in your heart arteries as the presence and type of heart artery blockage is a very important predictor of heart attack and death from heart attack.
