X-Ray Imaging ‍plays a Key Role in COVID-19 Diagnosis

⁣ updated June​ 09, 2025

As the COVID-19 pandemic continues, medical imaging, including ‍X-ray technology, remains⁤ a critical tool ‍for diagnosis and assessment. While real-time polymerase chain reaction (RT-PCR) tests are the primary method‌ for detecting the SARS-CoV-2 virus, X-ray ‌imaging offers​ unique ⁣advantages, especially in specific clinical scenarios.

Navjot Singh, President –​ Medical Imaging, Trivitron Healthcare, highlighted the importance of X-ray imaging in the COVID-19⁤ assessment. The infection, ‌caused by the⁣ SARS-CoV-2 ‍virus, leads to respiratory​ distress and spreads easily.

Although ​chest X-rays have lower⁣ sensitivity (25% to 69%) compared to other imaging techniques, their specificity—the ability to correctly identify the​ absence of‍ the disease—can ⁣reach up to 90%. The timing of the X-ray in relation to the onset of symptoms‌ is⁢ crucial. Findings may not be evident within the ⁤first three days of symptoms but become ⁣more apparent after​ 10 to ‍12 days.

Common X-ray ⁤findings in COVID-19 patients include consolidation (fluid accumulation in ​the lungs), ground-glass opacity, and ​nodular shadowing, primarily affecting the peripheral⁤ and lower lung ​areas.

While computed tomography (CT) scans are ⁣often preferred,X-ray technology offers practical benefits. X-ray equipment is easier⁣ to⁢ disinfect,reducing the risk of contamination. Moreover, ‌mobile X-ray units, such as Kiran’s Ultisys‌ 3.5,can be ‌brought ​directly to a patient’s bedside,minimizing‍ the potential for viral transmission.

The integration of Picture Archiving and Communication ‍Systems ‍(PACS) with⁣ X-ray units allows for cost-effective data storage⁣ and transmission, further reducing human exposure.

What’s next

Medical ⁣societies continue to refine guidelines for ​imaging in COVID-19.While chest X-rays ‌may be ⁢less sensitive in the early⁢ stages,‌ they remain valuable for examining ​quarantined patients with advanced symptoms, ‍aiding in diagnosis and management.
