Lung Ultrasound

Lung Pathology

  • Pleural effusions, types of fluid collection and Pleural Tap.
  • B lines
  • Pleural fluid (B mode and M mode) and giving qualitative estimates of the amount of pleural fluid as well as the echogenicity / nature of the fluid.
  • Pneumothorax and its mimics including absent lung sliding, the lung point and absence of B lines, and use of M-mode.
  • Pulmonary oedema and the differences between cardiogenic and inflammatory causes of oedema.
  • Pulmonary fibrosis
  • Pulmonary consolidation
  • Paralysed hemidiaphragm
  • B-pattern (formerly known as ‘lung rockets’ or ‘lung comets’)
  • Consolidation, abscess, air bronchograms, contusion, infarction
  • Pleural thickening

Views

  • Representative videos of lung bilaterally.
  • Generally anterior, lateral and posterior images are taken which should include the images of the costophrenic recesses
  • Specific videos should be recorded at sites of symptoms (e.g. pain) or signs (e.g. crackles)
  • For Pleural Effusions – Chest wall depth and either depth to lung or effusion depth should be recorded.

Credentialing Requirements

  • Completion of Accredited Course, ACEM Online module or Online Training Module (UTEC / ICN)
  • Attend our ED Workshop or arranged 1-on-1 sessions with members of US-SIG.
  • Two formative assessments, directly supervised by qualified assessor (see below) with suggestions and advice provided during the scan.
  • One summative assessment using the provided competence form.
  • 25 scans in total (including 3 directly supervised assessments).
  • At least 50% clinically indicated
  • At least 5 positive (demonstrating the above pathology)
  • All cases must be compared with gold standard findings (such as comprehensive imaging, pathological findings or if these are unavailable then clinical course).
  • Evidence of completion of logbook signed off by a suitably qualified supervisor (DDU, Radiologist, DMU or AMS or sonographer registered with NZ MRTB in the relevant field, CCPU in the relevant field or PGCert / Dip of Clinical Ultrasound).
  • Those cases that involve a procedural component must be signed off by a suitable assessor who performs those procedures themselves.

Definition of Sonologist

A sonologist is used to include practitioners who have successfully completed this credentialing process or equivalent (DDU, Radiologist, DMU or AMS or sonographer registered with NZ MRTB in the relevant field, CCPU in the relevant field or PGCert / Dip of Clinical Ultrasound).
