Purpose To validate the clinical efficacy of 7-minute threefold parallel imaging (PIx3)-accelerated DL super-resolution shoulder MRI against arthroscopic findings. Materials and Methods Adults with painful shoulder conditions who underwent PIx3-accelerated DL super-resolution 3-T shoulder MRI and arthroscopy between March and November 2023 were included in this retrospective study. Seven radiologists independently evaluated the MRI scan quality parameters and the presence of artifacts (Likert scale rating ranging from 1 [very bad/severe] to 5 [very good/absent]) as well as the presence of rotator cuff tears, superior and anteroinferior labral tears, biceps tendon tears, cartilage defects, Hill-Sachs lesions, Bankart fractures, and subacromial-subdeltoid bursitis. Interreader agreement based on κ values was evaluated, and diagnostic performance testing was conducted. Results A total of 121 adults (mean age, 55 years ± 14 [SD]; 75 male) who underwent MRI and arthroscopy within a median of 39 days (range, 1-90 days) were evaluated. The overall image quality was good (median rating, 4 [IQR, 4-4]), with high reader agreement (κ ≥ 0.86). Motion artifacts and image noise were minimal (rating of 4 [IQR, 4-4] for each), and reconstruction artifacts were absent (rating of 5 [IQR, 5-5]). Arthroscopy-validated abnormalities were detected with good or better interreader agreement (κ ≥ 0.68). The sensitivity, specificity, accuracy, and area under the receiver operating characteristic curve were 89%, 90%, 89%, and 0.89, respectively, for supraspinatus-infraspinatus tendon tears; 82%, 63%, 68%, and 0.68 for subscapularis tendon tears; 93%, 73%, 86%, and 0.83 for superior labral tears; 100%, 100%, 100%, and 1.00 for anteroinferior labral tears; 68%, 90%, 82%, and 0.80 for biceps tendon tears; 42%, 93%, 81%, and 0.64 for cartilage defects; 93%, 99%, 98%, and 0.94 for Hill-Sachs deformities; 100%, 99%, 99%, and 1.00 for osseous Bankart lesions; and 97%, 63%, 92%, and 0.80 for subacromial-subdeltoid bursitis. Conclusion Seven-minute PIx3-accelerated DL super-resolution 3-T shoulder MRI has good diagnostic performance for diagnosing tendinous, labral, and osteocartilaginous abnormalities. © RSNA, 2025 <i>Supplemental material is available for this article.</i> See also the editorial by Tuite in this issue.</p>","PeriodicalId":20896,"journal":{"name":"Radiology","volume":"314 2","pages":"e241351"},"PeriodicalIF":12.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143441739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Purpose To evaluate the impact of SARS-CoV-2 infection on coronary inflammation and plaques by using coronary CT angiography (CCTA) and the impact on clinical outcomes. Materials and Methods This retrospective analysis of a prospective study included consecutive patients who underwent serial CCTA between September 2018 and October 2023. The quantitative total and compositional percent atheroma volume (PAV) and annualized PAV change, presence of high-risk plaque, and attenuation of lesion-specific pericoronary adipose tissue (PCAT) at baseline and follow-up were compared between lesions in patients with and without SARS-CoV-2 infection. Relationships between SARS-CoV-2 infection and target lesion failure, which is a composite of cardiac death, target lesion myocardial infarction, and clinically driven target lesion revascularizations, were assessed with Cox models and log-rank tests. Results In 803 patients (mean age, 63.9 years ± 10.1 [SD]; 543 [67.6%] male patients), 2108 coronary artery lesions were evaluated in patients with SARS-CoV-2 infection (<i>n</i> = 690) and 480 coronary artery lesions were evaluated in patients without SARS-CoV-2 infection (<i>n</i> = 113). Compared with lesions in patients without SARS-CoV-2 infection, lesions in patients with SARS-CoV-2 infection demonstrated more rapid progression of overall PAV (0.90% per year ± 0.91 vs 0.62% per year ± 0.68, respectively; <i>P</i> < .001) and noncalcified PAV (0.78% per year ± 0.79 vs 0.42% per year ± 0.45, respectively; <i>P</i> < .001). The incidence of becoming high-risk plaque (21.0% [442 of 2108] vs 15.8% [76 of 480]; <i>P</i> = .03) and PCAT attenuation of -70.1 HU or higher (27.1% [571 of 2108] vs 19.8% [95 of 480]; <i>P</i> < .001) at follow-up was also greater in lesions in patients with SARS-CoV-2 infection (<i>P</i> < .001), despite similar prevalence at baseline. Lesions in patients with COVID-19 had a higher risk of target lesion failure (10.4% vs 3.1%, respectively; adjusted hazard ratio, 2.90; 95% CI: 1.68, 5.02; <i>P</i> < .001). Conclusion SARS-CoV-2 infection was associated with a more rapid progression of lesion-based plaque volume and an increase in incidence of becoming high-risk plaque. Coronary plaques among patients who experienced COVID-19 were more prone to having an elevated risk of target lesion failure. Clinical trial registration no.

Although hormonal regulation of BPE at breast MRI has been investigated, information regarding hormonal regulation of BPE at contrast-enhanced mammography (CEM) remains scarce. Purpose To investigate how BPE at CEM changes across various short- and long-term physiologic and pharmacologic hormonal effects, including menopausal status, lactation, hormone replacement therapy (HRT), and tamoxifen therapy and its cessation. Materials and Methods This retrospective study included CEM examinations performed between December 2012 and January 2024. A computational search was performed to identify CEMs performed in patients with various hormonal statuses and several subgroups of patients were identified, including premenopausal, postmenopausal, lactating, HRT, and tamoxifen subgroups. For patients who received tamoxifen therapy, the first follow-up image at treatment cessation was included, when available. The four ordinal BPE grades, ranging from minimal to marked, as reported in the official radiologic reports were used for analysis. Subgroup comparisons were performed using the Kruskal-Wallis rank sum test and χ² test or Fisher exact test.

High-yield diagnostic interpretation considers the underlying surgical approach (anterior vs posterior), the time elapsed since surgery, and the clinical status of the patient to reliably differentiate expected postoperative changes from surgical complications. As cervical anatomy, such as the foramina and nerve roots, is smaller than that of the lumbar spine, MRI acquisition challenges include the demand for higher spatial resolution. Another unique challenge for cervical spine MRI is susceptibility to motion artifacts from swallowing, breathing, and cerebrospinal fluid pulsation. Modified MRI protocols, including the use of metal artifact suppression techniques, can help mitigate susceptibility artifacts from metallic implants.

Bronchial artery yttrium 90 (⁹⁰Y) radioembolization may be a therapeutic option for these patients. Purpose To evaluate the feasibility of bronchial artery ⁹⁰Y radioembolization using technetium 99m (^99mTc) macroaggregated albumin (MAA) injection as a surrogate for ⁹⁰Y microspheres and to use SPECT/CT dosimetry to assess ^99mTc-MAA distribution and calculated anticipated ⁹⁰Y doses to tumors and OARs. Materials and Methods In this prospective clinical trial, study participants with either primary lung cancer or pulmonary metastases were enrolled between August 2020 and October 2023 from a single academic medical center. All participants underwent bronchial artery embolization for malignancy-induced hemoptysis prophylaxis. ^99mTc-MAA was injected via bronchial arteries, followed by bland embolization. SPECT/CT imaging and Monte Carlo simulations were used to evaluate ^99mTc-MAA distribution and predict ⁹⁰Y doses. Predicted ⁹⁰Y doses to tumors and OARs are reported as means ± SDs. Results Eight participants (mean age, 63.0 years ± 13.58; six [75%] male participants) were included. All had ultracentral tumors, and four had four or more tumors. SPECT/CT revealed a concentrated ^99mTc-MAA accumulation in tumors, with a mean tumor-to-normal tissue ratio of 22.71 ± 20.17. Simulations indicated that a ⁹⁰Y biologically effective dose (α/β ratio of 10 Gy) of 175.7-3173.6 Gy (mean, 778.8 Gy ± 981.9) could be delivered to all tumors while remaining under OAR toxicity thresholds. Conclusion SPECT/CT dosimetric analysis of ^99mTc-MAA injected via the bronchial artery for pulmonary malignancy suggests that bronchial artery ⁹⁰Y radioembolization is feasible and could be an alternative treatment for patients unable to receive external beam radiation therapy.
