This process, while potentially stressful, can lead to a rewarding career. This article aims to demystify the NRMP Match for IMGs by outlining its distinct phases, from the United States Medical Licensing Examination (USMLE) completion and the Educational Commission for Foreign Medical Graduates (ECFMG) certification to application preparation, interviews, ranking, and Match Week, including the Supplemental Offer and Acceptance Program (SOAP). It highlights common hurdles IMGs face, such as navigating visa requirements, securing U.S. clinical experience, obtaining strong letters of recommendation, and articulating unique strengths from international training. Actionable strategies are provided, emphasizing proactive planning, strategic program research and signaling, effective communication, and network building. The importance of understanding tools like program and geographic preference signaling is also discussed. While acknowledging the evolving nature of Match dynamics and the subjective aspects of some advice, this guide underscores that informed preparation and strategic engagement can significantly enhance an IMG's prospects. IMGs bring valuable diversity and skills to the U.S. healthcare system, and with a well-planned approach, they can successfully navigate the competitive radiology Match process.","PeriodicalId":93969,"journal":{"name":"Current problems in diagnostic radiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145208587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Computed tomography (CT) imaging is the cornerstone for diagnostic evaluation, reliably identifying characteristic radiographic patterns such as organizing pneumonia, hypersensitivity pneumonitis-like reactions, and diffuse alveolar damage. The diagnostic challenge lies in distinguishing these immune-mediated pulmonary injuries from infectious etiologies, radiation-induced lung injury, and neoplastic progression, each requiring distinct therapeutic interventions. Contemporary management protocols employ glucocorticoid therapy dosed according to toxicity severity, while investigational approaches explore targeted immunomodulators. This review synthesizes current evidence regarding radiographic manifestations, diagnostic pathways, and therapeutic algorithms, offering radiologists a structured approach to evaluating ICI-associated pulmonary complications. We highlight recent advances, including quantitative CT analysis and serum biomarkers, that promise to refine early detection and risk stratification.","PeriodicalId":93969,"journal":{"name":"Current problems in diagnostic radiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145182435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultrasound SWE was performed on the placenta, and mean SWE and velocity values were derived from six measurements. Both the cases and controls were followed to record Apgar scores and NICU admission. Statistical analysis was done, and the SWE values were compared to correlate these values with perinatal outcomes.Results: A positive correlation was observed between SWE values and maternal fasting blood glucose (FBS) levels (rho = 0.32, p = 0.001), indicating that higher glucose levels are associated with increased placental stiffness. In the control group, the mean SWE was 2.48 kPa, while in the GDM group, it increased to 7.74 kPa, reflecting the impact of a diabetic environment on placental stiffness. The mean velocity was also higher in the GDM group (1.47 m/s) as compared to the control group (mean = 0.87 m/s). A moderate negative correlation between APGAR (1-min) and mean SWE was found at <32 weeks of gestation (rho = -0.48, p = 0.017). No significant correlation was found with NICU admissions.Conclusion: Placental stiffness differs significantly between GDM and controls, with higher values in GDM. Ultrasound SWE can substantially contribute to the management of GDM and improve the outcomes. A negative correlation between SWE and 1-minute APGAR score at <32 weeks of gestation is associated with a lower score, indicating the effect of increased placental stiffness on perinatal outcomes.","PeriodicalId":93969,"journal":{"name":"Current problems in diagnostic radiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145182405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This evaluation is intended to help formulate the most effective preoperative plan and guide clinical decision-making. A retrospective study of 350 HPT cases in King Abdul-Aziz University Hospital over a period spanning 2012 to 2023 was carried out. Sensitivity, specificity, and receiver operator characteristic curve AUC were used to determine the diagnostic performance of ultrasonography, 99mTc-sestamibi scintigraphy, and combined imaging to the standard of biochemical PTH levels. The statistical tests involved the McNemar test and logistic regression to evaluate the predictors such as chronic kidney disease (CKD). The combined imaging demonstrated diagnostic accuracy of 0.69 compared to 0.74 and 0.64 of scintigraphy and ultrasonography respectively. The scintigraphy had a total of 161 true positives and 73 false negative results whereas ultrasonography had a total of 139 true positives and 95 false negative results. CKD was also a good determinant in HPT (odds ratio = 1.988, p = 0.026). According to the McNemar test, there was no significant difference between ultrasonography and scintigraphy (p = 0.494). The diagnostic inaccuracy of ultrasonography is lower in diagnosing HPT as compared to scintigraphy, however using combined imaging may provide more reliability in diagnosis hence it can be used in preoperative planning, especially in patients with CKD.","PeriodicalId":93969,"journal":{"name":"Current problems in diagnostic radiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145042778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic resonance imaging (MRI) is considered the gold standard but is often limited by cost and availability. This study aimed to prospectively compare the diagnostic performance of full-field digital mammography (FFDM), digital breast tomosynthesis (DBT), contrast-enhanced mammography (CEM), and MRI for tumor detection and size estimation in patients eligible for upfront surgery.Materials and methods: This single-center, prospective study included 46 women with histologically confirmed early-stage invasive breast cancer. All patients underwent FFDM, DBT, CEM, and MRI within one week prior to surgery. Histopathology served as the reference standard. Tumor size measurements were compared using Pearson's correlation coefficients (r), with concordance defined as a size difference within ±10 mm. Detection rates, size accuracy, and ability to identify multifocal lesions were evaluated.Results: The mean patient age was 55.4 years. FFDM identified the primary tumor in 89.1% of cases, DBT in 97.8%, and both CEM and MRI in 100%. Tumor size correlation with pathology was highest for MRI (r=0.811), followed by CEM (r=0.660), DBT (r=0.636), and FFDM (r=0.314). Concordance with pathology was 80.4% for MRI, 71.7% for CEM and DBT, and 58.7% for FFDM. Multifocal disease was detected in 15.2% of cases by MRI, 8.7% by DBT, and 6.5% by CEM.Conclusion: CEM and DBT showed strong diagnostic performance and may serve as accessible and cost-effective alternatives to MRI for preoperative staging in early-stage breast cancer. These modalities offer valuable imaging options in settings where MRI is limited or contraindicated.","PeriodicalId":93969,"journal":{"name":"Current problems in diagnostic radiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144983578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
