Meeting the COVID Crisis with Ultrasound Diagnosis
Studies are now recommending the use of an ultrasound machine for early diagnosis in COVID-19 patients. An ultrasound scan can give similar results to a CT scan of the chest, with many additional advantages. COVID-19 generally begins near the plueral line in the lung which can be clearly observed by an ultrasound of the lung.
Advantages of Lung Ultrasound in COVID-19 Cases:
- Can be performed at bedside
- Reduce exposure to healthcare workers
- No radiation exposure
- Lower cost than other tests
- Easy application and repeatable
- Easier to disinfect
Indications of COVID-19 in Ultrasound Imaging:
- Thickened pleural line
- B lines (multifocal, discrete, or confluent)
- Confluent B lines
- Small (centomeric) consolidations)
- Both non-translobar and translobar consolidation
- Multilobar distribution of abnormalities
- Pleural effusion is rare
Early Stage with mild infection: Focal B lines.
Progressive Stage with critical infection: Alveolar interstitial syndrome.
Pulmonary Fibrosis in patients: A lines found in the convalescence; pleural line thickening and uneven B lines.
