Patent ductus arteriosus MRI

Introduction

Overview

Overview

Magnetic resonance imaging can be helpful as a diagnostic tool in conditions where the echocardiographic findings are inconclusive.

MRI

MRI

Magnetic resonance imaging (MRI) can be used as a diagnostic modality in congenital heart diseases.[1][2][3][4][5][6]

Advantages

Disadvantages

  • For successful MRI procedure breath-holding is required, which is sometimes difficult to achieve with small kids. Due to this, the procedure is done under general anesthesia in children.
  • In patients with patent ductus arteriosus, the usage of MRI can demonstrate the abnormality and its severity. The magnitude of the shunt can also be determined by radionuclide flow studies.
Cardiac MRI demonstrates a patent ductus arteriosus. Pulmonary angiogram shows flow from the pulmonary artery to the descending aorta through a patent ductus (arrow), measuring 8 mm wide and 15 mm in length. RV: right ventricle; MPA: main pulmonary artery; PDA: patent ductus arteriosus; Des Ao: descending aorta. Case courtesy by Jaime Alfonso M. Aherrera et al.[7]
