  1. Registration of Coronary Arteries through Electroanatomical Mapping System with CT Angiography

    Rochester, MN

    Registration of Coronary Arteries through Electroanatomical Mapping System with CT Angiography

    • Location:

      Observational What is this?

      Describes the nature of a clinical study. Types include:

      • Observational study — observes people and measures outcomes without affecting results.
      • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
      • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

    About this study

    This study aims to perform a prospective analysis of patients undergoing fibrillation ablations and compare the validity of the electroanatomical registration with superimposed angiography. In addition, this study aims to compare and understand the relationship between the cardiac vessels.

  2. Dynamic Assessment of Vascular Run-Offs using a Multi-phase Protocol and Reduced Contrast Bolus

    Rochester, MN

    Dynamic Assessment of Vascular Run-Offs using a Multi-phase Protocol and Reduced Contrast Bolus

    • Location:

      Interventional What is this?

      Describes the nature of a clinical study. Types include:

      • Observational study — observes people and measures outcomes without affecting results.
      • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
      • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

    About this study

    The purposes for this study are to determine the ability of volumetric dynamic 4D CTA compared to replace current single-phase CTA and eliminate venous contamination that can decrease scan accuracy. Additionally, we seek to estimate the ability of this new imaging technique (volumetric dynamic 4D CTA) to reduce the dose of intravenous iodine and radiation dose.

  3. Coronary CTA for Radiation Therapy Planning in Lymphoma Patients

    Rochester, MN

    Coronary CTA for Radiation Therapy Planning in Lymphoma Patients

    • Location:

      Interventional What is this?

      Describes the nature of a clinical study. Types include:

      • Observational study — observes people and measures outcomes without affecting results.
      • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.

    About this study

    Our purpose for this study is to help design a therapy plan that can decrease extra radiation exposure to your heart during radiotherapy. The therapy plan will use images obtained using a dual-source CT scanner

    About this study

    3D angiography (3DA) imaging is a valuable method for assessing cardiovascular anatomy prior to and following trans-catheter intervention.  Current 3DA contributes substantially to the overall patient radiation dose for these procedures.  The purpose of this work is to assess the clinical efficacy of reduced radiation dose 3DA.
