On behalf of either a plaintiff or defendant, law firm clients frequently call on Cahn Litigation Services to locate an imaging expert witness to support litigation. An imaging expert witness needs substantive expertise, as well as possess the ability to explain evidence to a judge and jurors. An imaging expert witness could provide expertise in intellectual property matters, such as a patent litigation, a trade secret dispute, or a patent case or proceeding in the International Trade Commission (ITC). An expert in imaging technology might also provide testimony in a torts matter like product liability, or a medical malpractice case or personal injury case.

Expert witness services by an imaging expert witness could include an imaging study, failure analysis, expert opinion, expert report, and courtroom testimony at a trial. In a high-profile case, or litigation involving a significant financial stake, a law firm may request a subject matter expert with prior expert witness testimony experience. In addition, clients may seek an imaging industry expert for pre-litigation consulting work. Cahn Litigation Services reviews each project in detail, and can help determine if the ideal expert should be a radiology expert witness, medical expert witness, interventional radiologist, physician, or diagnostic radiologist. Whether the case involves diagnostic radiology, medical imaging, diffusion tensor imaging, interventional radiology, magnetic resonance imaging (MRI), neuroradiology, traumatic brain injury or ultrasound, Cahn Litigation Services has the experience required to turn an expert witness search around quickly and provide the right balance of expertise and testimony to support each project and it nuances.
