Radiology Misreads in Oregon: Wrong or Never Read?

When a cancer or a fracture or a bleed shows up on an imaging study that was taken months earlier, the question that follows is almost always the same: was it visible then, and if it was, what happened?

That question has more than one answer, and Oregon law treats the answers differently. A radiologist who looked at the film and did not see the finding is in a different position from one who saw it and called it benign, and both are in a different position from a case where the report was correct and nobody acted on it.

This article explains those distinctions. It does not assess any particular study or case.

Three different failures that look identical from the outside

Radiology practice generally distinguishes several ways an abnormality goes unaddressed.

The first is a perceptual miss: the finding was present on the image, and the radiologist did not see it. Retrospective review of imaging routinely identifies findings that were visible but unreported at the time.

The second is an interpretive error: the radiologist saw the finding, described it, and reached the wrong conclusion about what it meant — calling a mass benign, or attributing an opacity to infection rather than tumor.

The third is a communication failure: the report was accurate and it named the abnormality, but it never reached the ordering clinician or the patient in a way that produced action.

From a patient's perspective these are indistinguishable — in every case the disease progressed. Legally they are separate questions, because they involve different conduct by different people and, in some settings, different rules.

The interpretation itself is measured against other physicians

Radiologists are physicians, and the duty in ORS 677.095(1) applies to them. A physician licensed to practice medicine or podiatry by the Oregon Medical Board "has the duty to use that degree of care, skill and diligence that is used by ordinarily careful physicians in the same or similar circumstances in the community of the physician or a similar community."¹ Subsection (2) states a parallel duty for physician associates.¹

That formulation matters in imaging cases for a reason that is easy to miss. The comparison is to ordinarily careful physicians, not to a perfect reader and not to what is obvious in hindsight to someone who already knows the diagnosis. A finding that is unmistakable on retrospective review — once the later scans have shown where to look — may or may not have been within the standard of care to identify prospectively. That gap between hindsight and contemporaneous reading is one of the central contested issues in these cases, and it is established through expert evidence rather than by the statute.

The distinction between a perceptual miss and an interpretive error tends to matter here too. A missed finding raises a question about the search. A mischaracterized finding raises a question about the reasoning applied to something the radiologist actually saw and documented.

Mammography carries its own federal notification rules

Mammography is regulated separately under federal law, and the rules reach further than the interpretation. Under 21 CFR 900.12(c)(2), "[e]ach facility shall provide each patient a summary of the mammography report written in lay terms within 30 calendar days of the mammographic examination …" — a summary the regulation requires to include specified identifying information and an assessment of breast density.²

The regulation shortens that period sharply for concerning results. Where the assessment is "Suspicious" or "Highly Suggestive of Malignancy," the facility must provide the patient the lay summary "within 7 calendar days of the final interpretation of the mammograms."² Those two deadlines run from different events, which is easy to overlook: the ordinary 30-day clock runs from the date of the examination, while the shortened 7-day clock runs from the final interpretation.

A parallel provision requires the written report to reach the patient's health care provider "as soon as possible, but no later than 30 days from the date of the mammography examination," and within 7 calendar days of the final interpretation for those same concerning assessments.² Patients who do not name a health care provider are to be sent the report itself within 30 days in addition to the lay-terms notification.²

This is a meaningful contrast with how results move in other settings. A duty that runs directly to the patient, on a fixed clock, with a shortened deadline for suspicious findings, creates a documentary record of what the facility was required to do and when.

Oregon adds a requirement on top of the federal one. The Oregon Health Authority states that 2013 Senate Bill 420 "directs health care facilities offering mammography services to provide an advisement in the form prescribed by the Oregon Health Authority to patients with dense breast tissue," and that such a facility "is required to have a written policy of when and how they will communicate cases of extreme breast density and heterogeneous breast density."³ Dense tissue reduces the sensitivity of mammography, which is why the advisement exists.

When the report was right and nothing happened

The third category is in some ways the most frustrating, because the imaging worked. The radiologist saw the finding, described it accurately, and recommended follow-up. The report then sat in a chart.

In that situation the question moves away from the radiologist and toward what happened downstream — whether the report reached the ordering clinician, whether anyone reviewed it, and whether the recommended follow-up was ever arranged. The record of transmission, acknowledgement and follow-up scheduling usually determines what is provable.

Radiology reports also frequently contain explicit follow-up recommendations, such as an interval repeat study or a biopsy. Those recommendations are part of the record, and whether they were communicated and acted on is a separate question from whether the interpretation was correct.

The deadlines

Oregon's medical-malpractice limitations period is ORS 12.110(4). An action "shall be commenced within two years from the date when the injury is first discovered or in the exercise of reasonable care should have been discovered." The subsection adds an outer limit: "However, notwithstanding the provisions of ORS 12.160, every such action shall be commenced within five years from the date of the treatment, omission or operation upon which the action is based …" Where fraud, deceit or misleading representation prevented an action within five years, the subsection allows two years from the date that conduct is discovered or reasonably should have been discovered.⁴

Imaging cases put real pressure on that structure, because the study and the diagnosis can be separated by years. The five-year period runs from the treatment or omission — here, the reading of the study — rather than from the day the true diagnosis arrives.

If the delay proves fatal, the claim moves under ORS 30.020(1), which requires the action to be commenced within three years after the injury causing the death is discovered or reasonably should have been discovered, and provides that "[i]n no case may an action be commenced later than the earliest of: (a) Three years after the death of the decedent; or (b) The longest of any other period for commencing an action under a statute of ultimate repose that applies to the act or omission causing the injury, including but not limited to the statutes of ultimate repose provided for in ORS 12.110 (4), 12.115, 12.135, 12.137 and 30.905."⁵ Because the ORS 12.110(4) repose runs from the date of the study rather than from the death, the outer deadline in an imaging case can fall earlier than three years after the death.⁴

What the file tends to show

An imaging case is unusually document-heavy. There is the study itself, which can be re-read by other radiologists. There is the report, which fixes what was described and what was recommended. And in mammography there is a federally mandated notification with a date attached to it.² Which of the three failures occurred is usually answerable from those materials, and the answer determines whose conduct is actually at issue.

This article is educational

This article describes Oregon law in general terms. It is not legal advice and does not create an attorney-client relationship.

Time limits matter. Most Oregon personal-injury and auto-accident claims must be filed within two years of the injury or accident. Medical malpractice claims must be filed within two years of when you knew or reasonably should have known of the negligence, with an outer limit of five years from the act itself (with a fraud exception). Wrongful death claims must be filed within three years of the date of death. Claims against public bodies (cities, counties, state agencies, public hospitals) require a notice of claim within 180 days. Missing these deadlines typically ends a case.
