ExamCard Purpose

ExamCard intended for use in sedated children in combination with the SENSE Cardiac coil.
Purpose of the ExamCard is to diagnose atypical septal defects such as sinus venosus defect with or wihtout partial anomalous pulmonary venous return - Morphology and shunt quantification.

All scans are adapted for high (100 beats/min) cardiac frequencies.

ExamCard Overview

C_ASD and PAPVR
Scan 1Surv 3x1
Scan 2Ref Syn-Cardiac : uses 8 NSA because no breathhold is possible
Scan 3Surv cor-sag : plan scan using single phase TFE with high TFE factor
Scan 4Inflow PE-no : gives nice pulmonary and systemic venous anatomy, as well as deliniation of atrial septum.
Scan 5Surv 2ch: plan 2 slices: 2chamber LA-LV and perpendicular to this plane and the ventricular septum.
Scan 6VFx 4ch 5sl : multislice & multiphase TFE.
Scan 7QF AAo : to assess aortic stroke volume for calculation of shunt volume and Qp/Qs ratio.
Scan 8QF MPA : to assess pulmonary stroke volume for calculation of shunt volume and Qp/Qs ratio.
Scan 9PC ASD cor : phase contrast "en-face" view of ASD. Plan in atrial septal plane.
Scan 10PC ASD sag : Phase contrast sagittal view of ASD.
Scan 11PC ASD 4ch : Phase contrast "4-chamber" view of ASD.

  Free-breathing, phase-contrast sequences used in multiple angulations to delineate

  atypical ASDs (arrows). Superior sinus venous ASD viewed in atrial septal plane (A)

  and sagittal plane (C) with corresponding phase images (B resp. D) displaying shunt

  flow through defect.

  Note in A the anomalous pulmonary veins (dotted arrows) from right upper lobe

  draining to SVC.

 

  PAPVR = partial anomalous pulmonary venous return

  SVD =  sinus venous ASD

  RA = right atrium

  LA = left atrium

  SVC = superior vena cava 

Patient preparation

Safety precautions

Personal and equipment to intubate and resuscitate must be available with any sedated procedure.

  • 6-h n.p.o.
  • iv-line for sedation
  • MR-compatible vital sign monitoring (continuous), including SpO2
  • ear protection
  • no skin-skin contact
  • no wire loops

 

Patient positioning

  • supine
  • head first
  • SENSE cardiac coil
  • respiratory belt
