As a result of this collision, Plaintiff sustained injuries. Defendants retained [Dr. Ryan T. Fitzgerald](https://expertwitnessprofiler.com/expert-witness/Ryan-Fitzgerald/1553150), a radiologist, and [Dr. Everett G. Robert](https://expertwitnessprofiler.com/expert-witness/Everett-Robert/1521670), a neurosurgeon, to testify as expert witnesses.  Robert opined that he would not recommend surgery and that Plaintiff’s injuries were not related to the automobile collision. Fitzgerald reviewed Plaintiff’s diagnostic imaging and he is expected to testify that the imaging “of the cervical and thoracic spine obtained post-Accident on February 19, 2022 revealed no objective findings of trauma but rather, exhibited chronic multilevel degenerative disease and numerous potential degenerative pain generators unrelated to the Accident.” As a result, the Plaintiff filed a _[Daubert](https://www.law.cornell.edu/wex/daubert_standard)_ motion _in limine_ to exclude or limit Ryan T. Fitzgerald’s testimony. ## **Radiology Expert Witness** [Ryan T. Fitzgerald](https://expertwitnessprofiler.com/expert-witness/Ryan-Fitzgerald/1553150) earned his medical degree from the University of Arkansas for Medical Sciences (UAMS) College of Medicine. He****specializes in neuroradiology. Fitzgerald joined Radiology Consultants in July of 2017 and is a member of the Radiology Support Communication and Alignment Network (R-SCAN) committee.

According to Plaintiff, allowing Fitzgerald to testify would confuse the jury, waste time, and present repetitive evidence, which could unfairly prejudice Plaintiff. Alternatively, Plaintiff requested that Fitzgerald’s testimony be limited to avoid redundancy with Robert’s testimony. Defendants asserted Fitzgerald’s testimony would benefit the jury by adding clarity and fostering the jury’s understanding of the complex imaging presented to them at trial. They pointed out that Plaintiff did not raise a _Daubert_ challenge to Fitzgerald’s testimony. Since Fitzgerald and Robert have different specialties, Defendants asserted that they formed their respective opinions based on different vantage points. A review of Robert and Fitzgerald’s expert reports reveals that their separate specialties led the doctors to approach their analyses of Plaintiff’s medical conditions from different vantage points. Robert is a neurosurgeon who performed an independent medical examination of Plaintiff. Fitzgerald is a radiologist, whose review was limited to the diagnostic imaging. Although Robert also referenced the diagnostic imaging, Fitzgerald has specific expertise in that area as a radiologist. Therefore, while there may be some overlap in their testimony, the Court held that the reports of Robert and Fitzgerald are not cumulative of each other. Coming to the same conclusion does not make the reports duplicative. Any objection to Robert and Fitzgerald’s conclusions are best addressed on cross examination. Considering that exclusion of evidence under [Rule 403](https://www.law.cornell.edu/rules/fre/rule_403#:~:text=The%20court%20may%20exclude%20relevant,or%20needlessly%20presenting%20cumulative%20evidence.) should occur only sparingly, the Court will allow Defendants to call both experts. However, testimony at trial may be limited to the extent that it is cumulative and causes undue delay. ## **Held** The Court denied Plaintiff Shaun E. Howard’s_ Daubert_ motion _in limine_ to exclude or limit the testimony of Ryan T. Fitzgerald. ## **Key Takeaway:** Robert is a neurosurgeon who performed an independent medical examination of Plaintiff. Fitzgerald is a radiologist, whose review was limited to the diagnostic imaging. Although Robert also referenced the diagnostic imaging, Fitzgerald has specific expertise in that area as a radiologist. Therefore, while there may be some overlap in their testimony, the Court held that the reports of Robert and Fitzgerald are not cumulative of each other. **Please refer to the blog previously published about this case:** [Neurosurgery Expert Witness’ Testimony Admitted Despite Lack of Textual Support](https://expertwitnessprofiler.com/neurosurgery-expert-witness-testimony-admitted-despite-lack-of-textual-support) ## **Case Details:** --- ## **You Might Also Like** ![Corrections Expert's Standard of Care Testimony Admitted](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-23T161938.085.jpg) [**Corrections Expert’s Standard of Care Testimony Admitted**](https://expertwitnessprofiler.com/radiology-expert-witness-testimony-admitted-despite-claims-of-cumulative-testimony/corrections-experts-standard-of-care-testimony-admitted)![Human Resources Expert Allowed to Opine on Termination](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-22T200052.311.jpg) [**Human Resources Expert Allowed to Opine on Termination**](https://expertwitnessprofiler.com/radiology-expert-witness-testimony-admitted-despite-claims-of-cumulative-testimony/human-resources-expert-allowed-to-opine-on-termination)![Neuropsychology Expert Not Allowed to Opine on Cognitive Decline](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-22T144728.528.jpg) [**Neuropsychology Expert Not Allowed to Opine on Cognitive Decline **](https://expertwitnessprofiler.com/radiology-expert-witness-testimony-admitted-despite-claims-of-cumulative-testimony/neuropsychology-expert-not-allowed-to-opine-on-cognitive-decline)![Human Factors Expert Not Allowed to Opine on the Tile](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-21T191749.960.jpg) [**Human Factors Expert Not Allowed to Opine on the Tile**](https://expertwitnessprofiler.com/radiology-expert-witness-testimony-admitted-despite-claims-of-cumulative-testimony/human-factors-expert-not-allowed-to-opine-on-the-tile)![Insurance Expert Not Allowed to Opine on Legal Duties](https://ewp-blog.expertwitnessprofiler.org/wp-content/uploads/2026/04/blog-pic-640X480-2026-04-21T155751.487.jpg) [**Insurance Expert Not Allowed to Opine on Legal Duties**](https://expertwitnessprofiler.com/radiology-expert-witness-testimony-admitted-despite-claims-of-cumulative-testimony/insurance-expert-not-allowed-to-opine-on-legal-duties)
