The use of CT lung imaging for COVID-19 has been the diagnostic standard for the last few months of the current epidemic. CT has the disadvantage of logistics (staff, patients, transport) and radiation exposure. Respiratory distress creates motion artifacts on images that may simulate pulmonary inflammation. Since the disease mutates often, frequent imaging may be required. Viral pneumonia is not diagnostically distinguishable from other viral inflammations in the lung so the argument for a screening modality is useful to separate the critically ill from those needing outpatient treatment. Dr. Klaus Lessnau, author of CHEST ULTRASOUND (Springer 2003), employs both CT and ultrasound imaging in clinical practice.

has been able to identify pulmonary viruses directly
Lung ultrasound has been used in emergency rooms since it was introduced to the Mt Sinai Med School (New York) Emergency Department in 2014 and is now used nationwide to diagnose pneumonia (viral or bacterial) in children which spares them unnecessary x-rays since it is so caccurate. It is like an electronic stethoscope since lung disease and heart failure producing pulmonary fluid buildup are diagnosed or confirmed with portable ultrasound units at the bedside. This is considered the best imaging tool to diagnose a collapsed lung in seconds which has proven lifesaving as a time saver for on the spot detection. While it was assumed that children are carriers and not clinically affected, Dr. Buonsenso is actively investigating this population and there are findings that are concerning with the expanded use of lung ultrasound in this understudied group.

ROBERT L. BARD, MD, PC, DABR, FASLMS - Advanced Imaging & Diagnostic Specialist
Having paved the way for the study of various cancers both clinically and academically, Dr. Robert Bard co-founded the 9/11 CancerScan program to bring additional diagnostic support to all first responders from Ground Zero. His main practice in midtown, NYC (Bard Diagnostic Imaging- www.CancerScan.com) uses the latest in digital Imaging technology has been also used to help guide biopsies and in many cases, even replicate much of the same reports of a clinical invasive biopsy. Imaging solutions such as high-powered Sonograms, Spectral Doppler, sonofluoroscopy, 3D/4D Image Reconstruction and the Spectral Doppler are safe, noninvasive, and does not use ionizing radiation. It is used as a complement to find anomalies and help diagnose the causes of pain, swelling and infection in the body’s internal organs while allowing the diagnostician the ability to zoom and ‘travel’ deep into the body for maximum exploration.
