Interventional Radiology expert witnesses

Interventional radiology involves a discrete set of image-guided procedures that no other medical specialty performs in quite the same way. When litigation turns on whether an arterial access was correctly placed, whether a hepatic embolization was indicated, whether a pneumothorax following a CT-guided biopsy was a recognized complication or a departure from standard care, the opinion needs to come from a physician with hands-on experience in those specific techniques. A general radiologist can address image interpretation, and a vascular surgeon can address operative anatomy, but neither can fully occupy the standard-of-care space reserved for a subspecialty-trained interventional radiologist. Retaining the correct expert early prevents gaps in the liability or causation narrative that opposing experts will be positioned to exploit.

Beyond standard-of-care opinions, an interventional radiologist expert witness can assess informed-consent documentation, evaluate whether complication rates disclosed to the patient aligned with published benchmarks for the specific procedure, and address whether post-procedure monitoring met institutional and specialty-society guidelines. These dimensions of the case often determine damages framing as much as the primary liability theory.

The majority of interventional radiology cases that reach litigation fall into several recurring categories. Vascular access complications — arterial injury, arteriovenous fistula formation, or retroperitoneal hematoma following catheter-based procedures — represent a significant portion of plaintiff matters. Biliary and drainage procedure complications, including bile duct injury or catheter dislodgement, arise in both hospital-defense and malpractice contexts. Image-guided biopsy cases involve questions of targeting accuracy, pneumothorax management, and whether the correct lesion was sampled. Embolization procedures — hepatic, uterine fibroid, peripheral vascular — generate cases around non-target embolization, ischemic complications, and patient selection. Inferior vena cava filter placement and retrieval cases involve both device-related and technique-related claims, and often intersect with product liability theories alongside standard-of-care analysis. Finally, thrombolytic and thrombectomy cases in acute stroke or peripheral arterial occlusion settings raise questions about procedural timing, patient selection, and hemorrhagic conversion risk.

Every interventional radiology profile in this directory goes through a structured credential review before activation. The process checks ABR board certification status, including whether the physician holds primary certification in interventional and diagnostic radiology or a Certificate of Added Qualification in vascular and interventional radiology. State medical license standing is verified in each state where the expert holds or has held a license, using publicly available board records. The CV is reviewed for documented fellowship training at an accredited program, clinical practice history, and any prior medicolegal experience. Publicly accessible disciplinary records, board actions, and malpractice settlement disclosures required by state law are reviewed and noted in the internal profile record. Experts are not listed based on self-attestation alone — each claim is checked against a primary source where one exists.

A typical engagement begins with a record review phase, during which the expert works through imaging studies, procedure reports, nursing notes, informed-consent documentation, and any relevant institutional protocols. Interventional radiology cases almost always require the expert to review the actual imaging — DICOM files or high-resolution digital studies — rather than relying on radiology reports alone, because the opinion often turns on what the images show compared to what was documented. Expect the record review to take longer than in purely cognitive-specialty cases, particularly when the study volumes are large or when pre- and post-procedure imaging comparisons are central to the causation theory.

Following record review, the expert will typically produce a written report setting out the standard of care as understood in the relevant clinical context, the specific deviation or conformity identified, and the causal link to the claimed injury. In deposition, interventional radiology experts are frequently questioned on procedural volumes, fellowship training, current practice setting, and familiarity with the specific device or technique involved. Selecting an expert whose clinical background closely mirrors the setting of the procedure at issue — academic medical center versus community hospital, high-volume versus moderate-volume practice — materially reduces surface area for impeachment on these points.

Under FRE 702 and the framework established by Daubert, a court will assess whether an interventional radiology expert's methodology is grounded in sufficient facts, reflects reliable principles and methods, and has been reliably applied to the facts of the case. For procedural specialties like interventional radiology, the reliability inquiry often centers on whether the standard-of-care opinion is traceable to published guidelines from recognized specialty societies, peer-reviewed procedural literature, or broadly accepted institutional benchmarks rather than solely to the expert's personal practice style. Counsel should confirm that the retained expert can identify the evidentiary basis for each element of the opinion and is familiar with current Society of Interventional Radiology quality improvement standards and practice guidelines, which courts have accepted as relevant reference points in defining the standard of care. Experts who maintain active membership and continuing education in subspecialty societies are better positioned to demonstrate that their methodology reflects the current state of the field rather than an outdated or idiosyncratic standard.
