Radiology referral quality directly impacts how radiologists interpret images and manage patient care. Our research sought to explore ChatGPT-4's ability to support decision-making regarding imaging examinations and the generation of radiology referrals within the emergency department (ED).
In a retrospective manner, five successive ED clinical notes were gathered for each of the following conditions: pulmonary embolism, obstructing kidney stones, acute appendicitis, diverticulitis, small bowel obstruction, acute cholecystitis, acute hip fracture, and testicular torsion. Forty cases were part of the overall count. Employing these notes as a basis, ChatGPT-4 was prompted to recommend the most appropriate imaging examinations and protocols. The radiology referrals were also generated by the chatbot. Two radiologists independently graded the referral's clarity, clinical significance, and differential diagnostic options, employing a scale ranging from 1 to 5. A comparative review of the ACR Appropriateness Criteria (AC) and emergency department (ED) examinations was conducted, alongside the chatbot's imaging recommendations. To evaluate the consistency of reader judgments, a linear weighted Cohen's kappa was calculated.
ChatGPT-4's imaging recommendations consistently followed the ACR AC and ED standards in all applications. Disparities in protocols were noted between ChatGPT and the ACR AC in two instances (5% of cases). Reviewers assessed ChatGPT-4-generated referrals, scoring clarity at 46 and 48, clinical relevance at 45 and 44, and a unanimous 49 for differential diagnosis. A moderate agreement existed among readers regarding the clinical significance and clarity of the findings, contrasting with a substantial agreement on the grading of differential diagnoses.
ChatGPT-4 has demonstrated its potential to facilitate the selection of imaging studies in specific clinical applications. Large language models, as an ancillary tool, can potentially elevate the quality of radiology referrals. To remain effective, radiologists should stay informed regarding this technology, and understand the possible complications and risks.
ChatGPT-4's capacity to support the selection of imaging studies for specific clinical cases is promising. As a supplementary tool, large language models may contribute to improved radiology referral quality. Proficiency in this technology requires radiologists to consistently update their knowledge, considering potential drawbacks and risks in order to provide the best patient care.

Large language models (LLMs) have achieved an impressive level of skill applicable to the medical profession. This research project aimed to investigate whether LLMs could predict the superior neuroradiologic imaging method, based on detailed clinical presentations. The authors also investigate the hypothesis that large language models might achieve superior results compared to an experienced neuroradiologist in this particular diagnostic task.
ChatGPT and Glass AI, a large language model specialized in healthcare from Glass Health, were activated. With the best suggestions from Glass AI and a neuroradiologist, ChatGPT was given the assignment of ranking the top three neuroimaging methods. 147 conditions were used to benchmark the responses in relation to the ACR Appropriateness Criteria. Docetaxel manufacturer Due to the stochasticity of the LLMs, each clinical scenario was input into each model twice. growth medium Utilizing the criteria, each output received a score on a scale of 3. Nonspecific answers received partial scoring.
ChatGPT's score, standing at 175, and Glass AI's score, at 183, demonstrated no statistically significant difference between them. A score of 219 for the neuroradiologist placed them far above the performance of both LLMs. The outputs of the large language models were evaluated for consistency, and ChatGPT's performance was found to be statistically significantly less consistent than the other model's. Significantly, statistically meaningful differences were found in the scores yielded by ChatGPT across various rank levels.
When presented with particular clinical situations, LLMs excel at choosing the right neuroradiologic imaging procedures. In a performance parallel to Glass AI, ChatGPT performed similarly, indicating that training with medical texts could lead to a considerable enhancement of its application functionality. Experienced neuroradiologists were not outperformed by LLMs, highlighting the ongoing necessity for enhanced LLM performance in medical applications.
The selection of suitable neuroradiologic imaging procedures is well-handled by LLMs when presented with detailed clinical scenarios. The identical performance of ChatGPT and Glass AI suggests that medical text training could significantly bolster ChatGPT's capabilities in this specific use case. LLMs' capabilities did not transcend those of an experienced neuroradiologist, indicating the ongoing need for development and improvement in medical technology.

A review of utilization patterns for diagnostic procedures among lung cancer screening participants within the National Lung Screening Trial.
Analyzing abstracted medical records from National Lung Screening Trial participants, we evaluated the application of imaging, invasive, and surgical procedures following lung cancer screening. Multiple imputation by chained equations was selected as the method for handling the missing data points. Analyzing procedure utilization for each type, we focused on the period within one year of the screening or up to the next screening, whichever came earlier. We considered both arms (low-dose CT [LDCT] versus chest X-ray [CXR]), and differentiated the analysis by screening results. Multivariable negative binomial regressions were also used to explore the factors that influence the occurrence of these procedures.
Subsequent to baseline screening, our sample group displayed 1765 and 467 procedures per 100 person-years, respectively, for those with false-positive and false-negative results. Surgical and invasive procedures were encountered with a degree of relative scarcity. The rate of subsequent follow-up imaging and invasive procedures among those who tested positive was 25% and 34% lower, respectively, in the LDCT screening group, in comparison to the CXR screening group. The utilization of invasive and surgical procedures was 37% and 34% lower at the first incidence screen than it was at the baseline, indicating a substantial decrease. Individuals with positive baseline results were six times more likely to have additional imaging performed than individuals with normal findings at baseline.
Screening methods impacted the application of imaging and invasive procedures for the evaluation of atypical findings, showing a lower rate of such procedures for LDCT compared to CXR. The prevalence of invasive and surgical workups decreased significantly after the subsequent screening compared to the baseline screening. Utilizations correlated with age, but this association was independent of gender, racial or ethnic identity, insurance type, or socioeconomic status.
Abnormal finding evaluations, employing imaging and invasive procedures, demonstrated a variation across different screening methods; LDCT exhibited a lower rate of utilization compared to CXR. The incidence of invasive and surgical procedures decreased significantly after the subsequent screening examinations compared to the baseline. The association between utilization and age was pronounced, but no such association was noted for gender, racial/ethnic background, insurance status, or income.

Employing natural language processing, this study aimed to develop and evaluate a quality assurance protocol for quickly resolving discrepancies between radiologists and an AI decision support system's interpretations of high-acuity CT studies, particularly when radiologists do not utilize the AI system's output.
High-acuity adult CT scans performed in a health system between March 1, 2020, and September 20, 2022, were interpreted using an AI decision support system (Aidoc) to identify instances of intracranial hemorrhage, cervical spine fractures, and pulmonary embolism. This QA workflow flagged CT studies meeting these three conditions: (1) negative radiologist reports, (2) AI DSS with a high probability of positive results, and (3) unreported AI DSS output. An automated email notification was sent to our dedicated quality team in these specific cases. In the event of discordance identified during a secondary review, signifying an initially missed diagnosis, addendum creation and communication documentation would be implemented.
A study of 111,674 high-acuity CT examinations, interpreted over 25 years alongside an AI-powered diagnostic support system, revealed a rate of missed diagnoses (intracranial hemorrhage, pulmonary embolus, and cervical spine fracture) of 0.002% (n=26). Of the 12,412 CT scans deemed positive by the AI decision support system, 4% (n=46) exhibited discrepancies, were not fully engaged, and required quality assurance review. In a review of the divergent situations, 26 out of 46 cases (57%) were considered to be accurate positives.
