Usefulness of imaging techniques in the diagnosis of zoonotic parasitic infections: A Review

Advancements in the diagnostic imaging techniques have facilitated the detection and management of parasitic zoonotic diseases more effectively. Increase in the global population and modern lifestyle has intensified the risk of exposure to contaminated food and water sources infecting millions of people across the globe. The parasitic infections may be of protozoal or helminthic origin. Non-invasive imaging techniques such as Computed Tomography, Radiography, Ultrasonography, Contrast-Enhanced Ultrasound, Magnetic Resonance Imaging along with Fundoscopy, Endoscopy, Endoscopic Retrograde Cholangiopancreatography, and Colonoscopy have revolutionized the diagnosis of parasitic diseases. These imaging techniques promotes visualization of the parasites with its location and extent of the damage across various organs. Imaging techniques along with clinical history, examination and laboratory findings helps in the early intervention, effective management, and appropriate treatment of the diseases especially in areas with denser population and poor sanitation. This review emphasizes the necessity for enhanced surveillance, community education, and collaboration across the medical and veterinary sectors in mitigation of the global burden of zoonotic parasitic infections.
