Background
Point-of-care ultrasound (POCUS) is a relatively new and inexpensive technology that is rapidly proliferating throughout medical school education and clinical care as the 21st century’s version of the stethoscope. Emerging general medical reports support POCUS for minor bedside procedures such as thoracentesis and central venous line placement, though relatively little is published in the Radiology literature. Conventional ultrasound machine availability may be limited at bedside, as well as challenging to adequately protect from contamination from nosocomial pathogens, such as COVID-19. Most patients undergoing image guided biopsies and drainages of fluid collections have had prior diagnostic imaging studies with conventional cross-sectional imaging. We aim to demonstrate the feasibility and safety of using a commercially available POCUS device for guidance in a variety of image-guided procedures germane to an interventional radiology practice.

Educational Goals / Teaching Points
POCUS image quality is adequate for many routine image-guided vascular access and non-vascular interventional procedures. POCUS portability and ease of covering facilitate the bed-side performance of image guided procedures, which can limit the spread of the nosocomial pathogens and the contamination of medical devices in Radiology. POCUS is cost effective. POCUS availability is a useful adjunct for evaluating patients in clinic and in patient rooms, where conventional ultrasound equipment availability may be limited.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
POCUS image quality is adequate for many routine image-guided procedures. Image quality excels for vascular access, drainage of thoraco-abdominal fluid collections, and biopsies of both superficial solid organs and most superficial mass lesions; image quality may be suboptimal for routine native kidneys and smaller thyroid nodule biopsies.

Conclusion
POCUS is an inexpensive, robust, and portable technology that may be embraced in an interventional radiologist practice. Adoption of POCUS can lead to increased availability of point-of-care imaging and reduced contamination of Radiology equipment.
