1. Optimizing 3D FLAIR imaging of endolymphatic hydrops: Benefits and limitations of deep learning reconstruction.
1. 优化内淋巴积水的3D FLAIR成像：深度学习重建的优势与局限性PMID:日期:2026-09-24The purpose of this study was to evaluate the influence of deep learning reconstruction (DLR) on image quality and diagnostic performance of three-dimensional (3D) fluid-attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI) of the inner ear. Fifty-three patients (32 women; mean age, 57.4 ± 16.1 [standard deviation (SD)] years) were prospectively included. All patients underwent 3D FLAIR MRI of the inner ear. Four MRI sequences were analyzed, including conventional FLAIR (acquisition time, 7 min 14 s), high-resolution FLAIR (6 min 54 s), DLR-FLAIR (6 min 54 s), and accelerated DLR-FLAIR (5 min 34 s). Signal-to-noise ratio (SNR) was measured for objective analysis. Two readers independently evaluated diagnostic performance using conventional 3D FLAIR images as the standard of reference, and image quality (i.e., motion artifacts, noise, edge sharpness, global quality). Interobserver agreement was assessed using kappa statistics and Bland Altman analysis. DLR significantly increased SNR compared to non-DLR sequences (P < 0.001), with the highest SNR values observed for DLR-FLAIR images (91.2 ± 29.2 [SD]). Subjective analysis showed significant noise reduction and improved global image quality with DLR-FLAIR images (P < 0.001). Sensitivities for the diagnosis of inner-ear findings of the different sequences ranged between 62.5% and 100% and specificities between 92.1% and 100%, with no significant differences between sequences. Interobserver agreement was substantial to almost perfect for most findings but decreased for subtle structures and with the accelerated DLR-FLAIR sequence. Bland Altman analysis showed no systematic bias but increased variability with DLR. DLR significantly improves image quality in 3D FLAIR imaging of the inner ear, without compromising diagnostic performance. However, it may influence interobserver variability, particularly for subtle findings and accelerated acquisitions, which may modify diagnostic behavior, highlighting the importance of adapted interpretation strategies.

3. Characterization of prostate MRI focal lesions by combining human reading, artificial intelligence and prostate-specific antigen density: A multi-reader study.
3. 结合人工阅片、人工智能与前列腺特异性抗原密度对前列腺MRI局灶性病变进行表征：一项多阅片者研究PMID:日期:2026-08-14The purpose of this study was to compare, across readers with varying experience, the characterisation of prostate MRI lesions as grade group (GG) ≥ 2 cancer, by using the PI-RADS version 2.1 (PI-RADSv2.1) score alone and by combining prostate specific antigen density (PSAd), the PI-RADSv2.1 score and the output of a radiomics-based algorithm (Q-CAD). The MULTI database in which 21 readers (seven experienced seniors, seven less-experienced seniors, seven juniors) had assigned a PI-RADSv2.1 score to 240 prostate MRI lesions was retrospectively used. The lesions were outlined by two independent experts to compute their Q-CAD score. For each reader, four biopsy strategies were simulated. PI-RADS and PI-RADS strategies triggered biopsy in PI-RADSv2.1 ≥ 3 and PI-RADSv2.1 ≥ 4 lesions respectively. Combined and Combined strategies triggered biopsy when at least two of the following conditions were fulfilled: positive PI-RADSv2.1 score (≥ 3 for Combined; ≥ 4 for Combined), positive Q-CAD score (≥ 0.45 in peripheral zone; ≥ 0.79 in transition zone), PSAd ≥ 0.15 ng/mL/cm. A total of 232 lesions were included. Using lesions' delineations by Expert 1 for the three readers' experience groups, the Combined strategy was significantly less sensitive for GG ≥ 2 cancers (87-88% vs. 91-96%; P = 0.026 to < 0.001), but significantly more specific (45%-55% vs. 15%-34%; P < 0.001) than the PI-RADS strategy. The Combined strategy was less sensitive than the PI-RADS strategy (84%-86% vs. 85%-91%) but the difference was significant only for less-experienced seniors (P = 0.023); it was significantly more specific (51%-63% vs. 27%-50%; P < 0.001) in all groups. The Combined strategy provided the highest net benefit for risk thresholds >12%-16%. Using lesions' delineations by Expert 2 yielded similar results. The combined strategies significantly increased specificity, at the cost of slightly reducing sensitivity for GG ≥ 2 cancers.

4. Association between low bone mineral density and subchondral insufficiency fractures of the knee in women, and influence of radial meniscal root tears.
4. 女性低骨密度与膝关节软骨下功能不全骨折之间的关联，以及放射状半月板根部撕裂的影响PMID:日期:2026-08-11The purpose of this study was to evaluate the association between systemic low bone mineral density (BMD) and subchondral insufficiency fracture (SIF) of the knee in women, and to explore whether this association is modified by radial meniscal tears. In this case-control study, women with and without MRI-confirmed SIF who had available dual-energy X-ray absorptiometry T-score measurements were included. Systemic BMD was categorized using T-scores. Multivariable logistic regression models with BMD as the exposure and SIF as the outcome, adjusting for age and body mass index were fitted. An exploratory stratified analysis to assess potential effect modification by meniscal radial tear status was also conducted. A total of 121 women with SIF (mean age, 69.1 ± 7.5 [standard deviation] years) and 124 controls (70.4 ± 8.3 [standard deviation] years) were analyzed. After adjustment, osteoporosis was associated with higher odds of SIF (odds ratio [OR], 2.29; 95% confidence interval [CI]: 1.03-5.09), whereas osteopenia (OR, 1.33; 95% CI: 0.69-2.55) showed no significant association. In exploratory stratified analysis to test for effect modification, there were no significant interactions between low BMD and radial root tears (P-interaction = 0.178). However, small strata likely limited the power to detect a significant effect modification, as evidenced by overlapping wide 95% CIs. Osteoporosis is associated with higher odds of SIF of the knee in women, while osteopenia is not.

5. Ultra-low dose chest-abdomen-pelvis CT with deep-learning image reconstruction for cancer follow-up: Impact on image quality and lesion detection.
5. 超低剂量胸部-腹部-盆腔CT结合深度学习图像重建用于癌症随访：对图像质量和病灶检测的影响PMID:日期:2026-08-11[中文摘要] 本研究旨在比较在肿瘤随访中，采用深度学习图像重建（DLR）算法重建的超低剂量（ULD）胸-腹-盆计算机断层扫描（CAP-CT）与标准剂量CT（STD-CT）在图像质量和病灶检出方面的差异。前瞻性纳入106例因肿瘤随访而接受CAP-CT的患者。每例患者均接受STD-CT和ULD-CT两种采集。ULD-CT图像采用两个DLR级别（Smooth/Smoother）进行重建。比较了剂量学指标、客观图像质量、主观图像质量及病灶检出情况。采用Gwet's AC1或AC2系数评估不同方案间及不同阅片者间的一致性。ULD-CT显著降低了辐射暴露，平均CTDI降低-71.5%，剂量长度乘积降低-71.5%（P < 0.05）。在大多数组织中，STD-CT与ULD-CT之间观察到微小但具有统计学意义的HU值差异。对于所有器官或组织，ULD-CT-Smooth的图像噪声显著高于STD-CT（P < 0.001），ULD-CT-Smoother的图像噪声亦显著高于STD-CT，但背侧椎体（P = 0.39）和气管（P = 0.26）除外。对于所有器官或组织，Smoother DLR级别的图像噪声显著低于Smooth DLR级别（P < 0.001）。STD-CT与ULD-CT在胸部、腹部和骨病灶检出方面的一致性几乎完美。ULD-CT对亚厘米级肝脏病灶的检出率较低，而对较大病灶（≥ 10 mm）的检出率保持相似。ULD-CT的主观图像质量较低，阅片者间一致性为中等，诊断信心低于STD-CT。两名阅片者中有一人认为19%-24%的ULD-CT检查无法判读。采用DLR的ULD-CT可大幅降低辐射剂量，但与STD-CT相比，图像质量较差，且对腹部小尺寸低对比度病灶的检出率较低。尽管胸部和骨骼病灶的检出率保持等效，但次优或无法判读检查的高比例可能限制ULD方案在肿瘤随访中的常规应用。
[英文摘要] The purpose of this study was to compare the image quality and lesion detection between ultra-low dose (ULD) chest-abdomen-pelvis computed tomography (CAP-CT) reconstructed with a deep-learning image reconstruction (DLR) algorithm, and standard-dose CT (STD-CT) in cancer follow-up. A total of 106 patients undergoing CAP-CT for the follow-up of cancer were prospectively included. Each patient underwent both STD-CT and ULD-CT acquisitions. ULD-CT images were reconstructed using two DLR levels (Smooth/Smoother). Dosimetric indicators, objective image quality, subjective image quality, and lesion detection were compared. Agreement between protocols and readers was assessed using Gwet's AC1 or AC2 coefficients. ULD-CT significantly reduced radiation exposure, with a mean CTDI reduction of -71.5% and dose-length product reduction of -71.5% (P < 0.05). Minor but statistically significant differences in HU values were observed between STD-CT and ULD-CT across most tissues. For all organs or tissues, image noise was significantly higher with ULD-CT-Smooth than with STD-CT (P < 0.001), and with ULD-CT-Smoother than with STD-CT, except for dorsal vertebra (P = 0.39) and trachea (P = 0.26). For all organs or tissues, image noise was significantly lower with the Smoother DLR level than with Smooth DLR level (P < 0.001). Agreement between STD-CT and ULD-CT regarding lesion detection was almost perfect for thoracic, abdominal, and bone lesions. Detection of infracentimetric hepatic was lower with ULD-CT, whereas detection of larger lesions (≥ 10 mm) remained similar. Subjective image quality was lower with ULD-CT, with moderate inter-reader agreement, and lower diagnostic confidence than with STD-CT. One of the two readers considered that 19%-24% of ULD-CT examinations were uninterpretable. ULD-CT with DLR offers substantial radiation dose reduction but resulted in poorer image quality and lower detection of small low-contrast abdominal lesions compared with STD-CT. Although lesion detection remained equivalent for thoracic and skeletal lesions, the high proportion of suboptimal or uninterpretable examinations may limit routine use of ULD protocols in cancer follow-up.

7. Association between radial meniscal tears with and without posterior root involvement and subchondral insufficiency fracture of the knee on MRI: The mediating role of meniscal extrusion.
7. MRI上有和没有后根受累的桡骨半月板撕裂与膝关节软骨下功能不全骨折之间的关联：半月板挤压的中介作用PMID:日期:2026-08-08The purpose of this study was to evaluate the relationship between subchondral insufficiency fracture (SIF) of the knee and radial meniscal tears on magnetic resonance imaging (MRI) and to examine within the medial compartment the potential mediating role of meniscal extrusion in this relationship. A retrospective matched case-control study of knee MRI examinations obtained from November 2021 to November 2024 was performed. MRIs were reviewed for SIF, meniscal tear morphology, and meniscal extrusion grade. Associations between radial tears and SIF (overall and medial compartment) were evaluated using conditional logistic regression adjusted for age, sex, and body mass index. Medial-compartment mediation was examined using a natural effects model with medial meniscal extrusion as the mediator. The cohort included 343 patients with SIF (65.4 ± 10.1 [standard deviation] years; 226 women) and 343 patients without SIF (66.4 ± 10.0 [standard deviation] years; 224 women). Compared with knees without radial tears, odds of SIF were higher in the presence of radial root tears (odds ratio [OR], 7.62; 95% confidence interval [CI]: 4.40-13.21) and radial non-root tears (OR, 5.26; 95% CI: 2.48-11.15), with similar findings in the medial compartment. In mediation analysis, medial radial root tears showed an indirect association with medial SIF through medial meniscal extrusion (OR, 1.46; 95% CI: 1.16-1.84), accounting for 16.6% of the total effect. Radial root and non-root tears are strongly associated with SIF on MRI, particularly in the medial compartment. Meniscal extrusion explained a small proportion of this association, suggesting that additional biomechanical pathways are likely in play.

9. Development and external validation of a dual-energy CT-biochemical score for the detection of radiolucent common bile duct stones.
PMID:日期:2026-08-03The purpose of this study was to evaluate the diagnostic performance of dual-energy computed tomography (DECT) effective atomic number (Z) mapping for detecting radiolucent common bile duct (CBD) stones and to develop and externally validate a simple, combined imaging-biochemical score. This retrospective multicenter study included consecutive adults who underwent magnetic resonance cholangiopancreatography (MRCP) due to suspected choledocholithiasis after a negative conventional abdominal dual-layer DECT performed within 21 days. In the derivation cohort, Z and electron-density maps were independently reviewed by two radiologists, with consensus adjudication for interreader disagreements, using MRCP as the reference standard for CBD stones. Variables associated with MRCP-confirmed stones were entered into a multivariable logistic regression to derive a simplified score (i.e., ZBG score) based on Z map positivity, conjugated bilirubin or gamma-glutamyl transferase serum levels, which was then validated in an external validation cohort. The derivation cohort included 100 patients (mean age, 65.8 ± 19.3 [standard deviation] years; 54 men), of whom 19 had radiolucent CBD stones. The validation cohort included 101 patients (mean age, 60.2 ± 19.4 [standard deviation] years; 49 men), of whom 17 had radiolucent CBD stones. Consensus Z mapping yielded 63% sensitivity (95% confidence interval [CI]: 38-84), 86% specificity (95% CI: 77-93), and 82% (95% CI: 73-89) accuracy for the diagnosis of radiolucent CBD stones. Z map positivity (odds ratio [OR], 18.69; 95% CI: 4.22-82.68; P < 0.001) and conjugated bilirubin ≥ 50 µmol/L and/or γ-glutamyl transferase > 500 IU/L (OR, 20.67; 95% CI: 3.39-126.09; P = 0.001) were two variables that were independently associated with CBD stones. These two variables were combined into the ZBG score, with 1 point assigned to each item. The resulting ZBG score (range: 0-2) showed an area under the curve of 0.870 (95% CI: 0.801-0.939) in the derivation cohort and 0.877 (95% CI: 0.791-0.963) in the validation cohort for the diagnosis of radiolucent CBD stones. For patients with suspected CBD stones and negative conventional CT results, a simple score combining DECT Z mapping and routine cholestatic biomarkers provides accurate risk stratification for radiolucent CBD stones.
