How is Medical Imaging for Patients With Multiple Conditions Complicated
When a patient arrives with several active medical conditions, the right protocol is only the beginning. Their ability to tolerate the exam often depends on clinical details set long before the scan.
Unfortunately, not every relevant detail reaches the radiology team. A 2025 clinical study reported incomplete or incorrect information in 16% of MRI safety assessments involving active implants. In a separate 2026 study, 40.58% of implanted devices identified during an institutional audit hadn't been disclosed on MRI request forms.
Although both studies focus on device documentation, they highlight a wider concern about information available during examination planning. For patients with multiple organ dysfunction, cognitive limitations, or complex equipment needs, incomplete preparation can affect examination feasibility and safety.
In this article, we will discuss the physiological, mechanical, and operational factors worth a closer look, particularly those easily missed during ordering and scheduling.
The Patient’s Ability to Tolerate Imaging
A patient can look stable on the ward and still struggle once the scan begins. Borderline oxygen saturation, labile blood pressure, or intermittent arrhythmia may only surface after thirty minutes flat inside the bore.
The consequences aren't limited to patient safety. Respiratory distress, for example, may prevent adequate breath-holding during abdominal MRI, producing motion artifacts that obscure important findings.
A 2025 report from the Radiological Society of North America emphasized this problem, particularly the difficulty of predicting breath-holding capacity before an examination. The report also examines acquisition techniques that can reduce respiratory motion artifacts.
Addressing these limitations requires more than adjusting imaging parameters. Radiologists need current clinical information to determine whether the examination requires additional monitoring, modified positioning, or alternative acquisition techniques.
Getting that information to radiology in time is a serious coordination task. Taking the assistance of a nurse with advanced training in care coordination can be useful in such cases.
Many of these nurses earn their expertise through a specialized Associate Degree in Nursing (RN) to Master of Science in Nursing (MSN) bridge program. The pathway focuses on graduate study in research, clinical reasoning, and diagnosis, notes Wilkes University.
Many accredited universities now offer RN to MSN online programs, reflecting the rising demand for nurses who connect bedside assessment with procedural planning. Before scheduling, these nurses can review oxygen requirements, recent hemodynamic trends, and cognitive status, then pass a short tolerance summary to radiology.
With this summary in hand, the team can determine breath-hold capacity, positioning, and monitoring needs well ahead of the exam. Nurses who complete the Psychiatric/Mental Health Nurse Practitioner (PMHNP) concentration can add another layer of support in such cases.
They’re trained to assess anxiety, agitation, and delirium, which are common reasons a patient can’t stay still or follow breath-hold commands. They can flag these risks early, coordinate with the ordering team, and recommend a sedation or monitoring plan before the day of the scan.
Cognitive and Behavioral Factors Affecting Image Acquisition
A well-planned protocol still depends on a patient who can follow it. Dementia, delirium, anxiety, and sensory sensitivity can each make stillness and breath-holds hard to achieve.
In patients with multiple conditions, these factors compound. For instance, a patient with dementia or acute delirium may struggle to remain motionless during a brain MRI. Similarly, an autistic patient with sensory sensitivities may experience considerable distress from scanner noise, unfamiliar surroundings, or physical positioning.
The problem usually shows up well before the examination itself. Ben Potts, a diagnostic radiographer researching neurodivergent patient experiences, highlighted this concern in comments to the Society of Radiographers. “Research has shown that 51 per cent of autistic people find waiting rooms unbearable - they’re too much of a sensory experience. That’s compared with 8 per cent of non-autistic people.”, he noted.
Sadly, a patient’s cognitive status remains largely undocumented at the point of referral. A 2026 study of 20 MRI encounters in Ireland found cognitive status undocumented on 85% of referrals. Only 25% of those patients fully understood instructions, and 15% of exams were aborted.
Radiologists can address some of these challenges by reviewing previous examination experiences and identifying sensory or communication needs before scheduling. Quieter waiting areas, clear explanations, caregiver involvement, and shorter acquisition protocols may improve tolerance.
When sedation is necessary, coexisting neurological or respiratory conditions require careful assessment with the anesthesia team.
Clinical Information Lost Between Referral and Imaging
An imaging referral may identify the suspected diagnosis without providing enough information about the patient's current condition. This becomes particularly problematic when several specialists are managing different aspects of care.
Consider a patient scheduled for contrast-enhanced CT who develops acute kidney injury after the original request. Their renal function now requires reassessment, although the imaging order may remain unchanged.
Incomplete referrals present another concern. A recent study by Insights into Imaging evaluated 1,291 emergency CT referrals. It found that only 22.2% met the criteria for adequate clinical information.
Researchers also identified an association between poorer referral quality and less accurate clinical reasoning, assessed against the final CT diagnosis. Although the study didn't examine changes in patient condition between referral and imaging, it highlights the limitations of relying on the initial request alone.
Radiologists can address this through targeted reviews of recent laboratory findings, clinical notes, and changes in treatment. Direct communication with referring physicians becomes particularly important when the patient's condition has changed. These checks can clarify whether the planned protocol remains appropriate and whether additional preparation or monitoring is needed.
FAQs
How should a limited or incomplete exam be documented in the report?
State which sequences or phases were affected and why, whether from motion, intolerance, or missing history. Then explain how this limits confidence in the findings and whether a repeat study or alternative modality would help. This keeps referring teams from over-reading a compromised exam.
Who decides whether a patient needs sedation for imaging?
The decision is usually shared among the radiologist, the ordering clinician, and the anesthesia or sedation team. They weigh airway and breathing status, neurological condition, expected scan time, and urgency. Local policy determines who administers sedation and how the patient is monitored afterward.
What can the team do when a patient becomes distressed mid-scan?
The technologist can pause the sequence and speak calmly with the patient through the intercom. The team then checks monitoring, comfort, and positioning, and brings in a nurse or caregiver. Together they decide whether to resume, shorten the protocol, or reschedule with added support.

The Ideal Scan Isn't Always the Right Scan
A completed examination doesn't always mean the clinical question has been answered. Sometimes, the more useful outcome comes from recognizing a limitation early enough to make a better decision.
Radiologists work within circumstances that aren't entirely predictable, particularly when patients have several competing medical needs. No amount of preparation can eliminate every complication, nor should every unusual requirement become a reason to postpone imaging.
The goal is to make informed decisions with the clinical information available, while recognizing when more context is needed. Ultimately, good imaging care leaves room for both diagnostic precision and the individual circumstances of the patient.
