Purpose To develop and evaluate an automated MRI segmentation model for robust segmentation of major anatomic structures independent of MRI sequence. Materials and Methods In this retrospective study, an nnU-Net model (TotalSegmentator MRI) was trained on MRI and CT scans to segment 80 anatomic structures relevant for use cases such as organ volumetry, disease characterization, surgical planning, and opportunistic screening. Images were randomly sampled from routine clinical studies to represent real-world examples. Dice scores were calculated between the predicted segmentations and expert radiologist segmentations to evaluate model performance on an internal test set and two external test sets and against two publicly available models and TotalSegmentator CT. The Wilcoxon signed rank test was used to compare model performance. The proposed model was applied to a separate internal dataset containing abdominal MRI scans to investigate age-dependent volume changes. Results A total of 1143 scans (616 MRI, 527 CT; median patient age, 61 years [IQR, 50-72 years]) were split into a training set (<i>n</i> = 1088; CT and MRI) and an internal test set (<i>n</i> = 55; MRI only). The two external test sets (AMOS and CHAOS) contained 20 MRI scans each, and the aging-study dataset contained 8672 abdominal MRI scans (median patient age, 59 years [IQR, 45-70 years]). The proposed model had a Dice score of 0.839 for the 80 anatomic structures in the internal test set and outperformed two other models (Dice score of 0.862 vs 0.759 for 40 anatomic structures and 0.838 vs 0.560 for 13 anatomic structures; <i>P</i> < .001 for both). On the TotalSegmentator CT test set (89 CT scans), the performance of the proposed model almost matched that of TotalSegmentator CT (Dice score, 0.966 vs 0.970; <i>P</i> < .001). The aging study demonstrated a strong correlation between age and organ volume (eg, age and liver volume: ρ = -0.096; <i>P</i> < .0001). Conclusion The proposed open-source, easy-to-use model allows for automatic, robust segmentation of 80 structures, extending the capabilities of TotalSegmentator to MRI scans from any MRI sequence.

Purpose To evaluate large language models (LLMs) for automatically generating clinical histories for oncologic imaging requisitions from clinical notes and compare them with original requisition histories. Materials and Methods In total, 207 patients with CT performed at a cancer center from January to November 2023 and with an electronic health record clinical note coinciding with ordering date were randomly selected. A multidisciplinary team informed selection of 10 parameters important for oncologic imaging history, including primary oncologic diagnosis, treatment history, and acute symptoms. Clinical notes were independently reviewed to establish the reference standard regarding presence of each parameter. After prompt engineering with seven patients, GPT-4 (version 0613; OpenAI) was prompted on April 9, 2024, to automatically generate structured clinical histories for the 200 remaining patients. Using the reference standard, LLM extraction performance was calculated (recall, precision, F1 score). LLM-generated and original requisition histories were compared for completeness (proportion including each parameter), and 10 radiologists performed pairwise comparison for quality, preference, and subjective likelihood of harm. Results For the 200 LLM-generated histories, GPT-4 performed well, extracting oncologic parameters from clinical notes (F1 = 0.983). Compared with original requisition histories, LLM-generated histories more frequently included parameters critical for radiologist interpretation, including primary oncologic diagnosis (99.5% vs 89% [199 and 178 of 200 histories, respectively]; <i>P</i> < .001), acute or worsening symptoms (15% vs 4% [29 and seven of 200]; <i>P</i> < .001), and relevant surgery (61% vs 12% [122 and 23 of 200]; <i>P</i> < .001). Radiologists preferred LLM-generated histories for imaging interpretation (89% vs 5%, 7% equal; <i>P</i> < .001), indicating they would enable more complete interpretation (86% vs 0%, 15% equal; <i>P</i> < .001) and have a lower likelihood of harm (3% vs 55%, 42% neither; <i>P</i> < .001). Conclusion An LLM enabled accurate automated clinical histories for oncologic imaging from clinical notes.

Purpose To characterize MRI features of type 2 leaks, correlate them with intraoperative observations, and evaluate their diagnostic value. Materials and Methods Patients with SIH and type 2 leaks diagnosed between January 2021 and February 2023 were retrospectively identified. Characteristic imaging features from heavily T2-weighted MR myelography (T2-MRM) images were reevaluated (independently and blinded) in the type 2 leak sample mixed with a sample of 40 patients with SIH and type 1 (ventral) leaks. Available intraoperative data were reviewed for lateral dural tears, arachnoid outpouching, and ruptured spinal meningeal diverticula. Results Twenty-eight patients with SIH (mean age, 37.3 years ± 8.2 [SD]; 22 [79%] female patients) had 29 type 2 leaks between the T7 and L2 levels without side predominance. Characteristic cystic lesions with a broad dural base on the exiting nerve root sleeve were identified at T2-MRM; this \"bud-on-branch\" sign reflects an arachnoid outpouching herniating through a lateral dural tear, distinct from a meningeal diverticulum, which yielded a sensitivity of 79% (22 of 28; 95% CI: 59, 92) and a specificity of 100% (40 of 40; 95% CI: 91, 100) for leak location. Arachnoid outpouching was confirmed intraoperatively in 23 of 25 patients (92%; 95% CI: 81, 100), originating from the nerve root sleeve axilla in most patients (19 of 25, 76%; 95% CI: 59, 93); two of 25 patients (8%; 95% CI: 0, 19) had a dural tear only, and none had an underlying ruptured meningeal diverticulum. Conclusion This study showed that type 2 leaks are actually due to a lateral dural nerve root sleeve tear through which the arachnoid herniates, which contrasted the common perception that these leaks result from ruptured meningeal diverticula.

Free-breathing phase-resolved functional lung (PREFUL) MRI may be useful for assessing lung function in pediatric patients with PCC. Purpose To detect lung changes in children and adolescents with PCC compared with healthy control participants using PREFUL MRI. Materials and Methods In this single-center, prospective, cross-sectional study conducted between April 2022 and April 2023, children and adolescents (age ≤17 years) with PCC and age- and sex-matched healthy participants underwent MRI. Subgroup analysis was performed in participants with PCC who had cardiopulmonary symptoms. Regional ventilation, flow-volume loop correlation metric (FVL-CM), quantified perfusion, ventilation and perfusion defect percentages, and ventilation-perfusion ratios were compared between participants with PCC and controls using the Wilcoxon signed rank test. Correlation of imaging parameters with spirometry, heart rate, respiratory rate, and Bell score (fatigue severity) in participants with PCC was assessed using the Spearman rank correlation coefficient. Results The final study sample included 54 participants (27 participants with PCC and 27 matched control participants; median age, 15 years [IQR, 11-17 years]; 14 male participants). Twenty-one participants had cardiopulmonary symptoms.

Participants with PCC and cardiopulmonary symptoms had lower FVL-CMs (median, 0.99 arbitrary units [au] [IQR, 0.98-0.99 au] vs 0.99 au [IQR, 0.99-0.99 au]; <i>P</i> = .01) and higher ventilation defect (median, 7.6% [IQR, 4.5%-15.1%] vs 5.4% [IQR, 2.7%-7.1%]; <i>P</i> = .047) and perfusion defect percentage (median, 3.2% [IQR, 2.4%-4.2%] vs 2.3% [IQR, 1.8%-3.5%]; <i>P</i> = .02) compared with matched control participants.
