AI-driven tools, especially in deep learning and machine learning, have shown remarkable potential in enhancing image recognition, analysis and decision-making. This technological advancement allows for the automation of routine tasks, improved diagnostic accuracy, and the reduction of human error, leading to more efficient workflows. Moreover, the successful implementation of AI in healthcare requires comprehensive education and training for young clinicians, with a pressing need to incorporate AI into residency programmes, ensuring that future specialists are equipped with traditional skills and a deep understanding of AI technologies and their clinical applications. This includes knowledge of software, data analysis, imaging informatics and ethical considerations surrounding AI use in medicine. By fostering interdisciplinary integration and emphasising AI education, healthcare professionals can fully harness AI's potential to improve patient outcomes and advance the field of medical imaging and therapy. This review aims to evaluate how AI influences radiology, nuclear medicine and radiation oncology, while highlighting the necessity for specialised AI training in medical education to ensure its successful clinical integration.","PeriodicalId":16218,"journal":{"name":"Journal of Medical Imaging and Radiation Oncology","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144591404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ultrasound is the first line of imaging for female pelvic masses. However, due to its inherent drawbacks, ultrasonography cannot delineate the origin of large masses that distort the normal relations between the pelvic organs. Contrast-enhanced MR imaging (CE-MRI) is a problem-solving tool due to its multidimensional imaging capabilities and soft tissue contrast. Imaging features such as the anatomical location, signal intensity of mass on T2W images, displacement/mass effect on adjacent pelvic/vascular structures and enhancement patterns are studied for making this distinction. A key aspect of this differentiation is the analysis of vascular anatomy, displacement of vessels and the patterns of enhancement. This pictorial essay discusses how the vascular supply, displacement of vessels and enhancement pattern of masses on MRI provide imaging clues which help in distinguishing uterine from adnexal masses.","PeriodicalId":16218,"journal":{"name":"Journal of Medical Imaging and Radiation Oncology","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144540518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients aged ≥ 85 years with histopathological solid malignancy. Demographic characteristics and comorbidities as well as performance status (ECOG), tumour characteristics, imaging modalities and treatment choices were variables. Patients were categorised according to PET-CT use, and statistical analyses including Mann-Whitney U test, Bonferroni correction and binary logistic regression were performed to identify independent predictors of PET-CT use.Results: The majority of patients had ECOG 2 (69%), thoracic (32%) cancer and metastatic (70%) at diagnosis, with a median age of 89 years (range: 85-99). Comorbidities were common (73%), and the most common organ dysfunctions were renal (25%) and heart failure (24%). PET-CT was performed in 47% of the patients. PET-CT was predominantly used in patients with metastatic disease, those who had received radiotherapy and those who were given best supportive care. However, patients undergoing PET-CT had significantly lower rates of curative treatment (3% vs. 18%, p = 0.0016). Binary logistic regression identified best supportive care decision as the only independent predictor of PET-CT use.Conclusions: The findings indicated that PET-CT is commonly used for staging in patients who are ultimately managed with palliative care.

Varicoceles can present in childhood and adolescence with scrotal pain or discomfort, or may be subclinical. It involves dilatation of the pampiniform plexus related to congestion and retrograde flow in the testicular vein. If left untreated, the pain and discomfort may impact the quality of life of the paediatric patient, and in the long term, infertility may ensue. However, limited data are available on the long-term clinical outcomes and complications of Varicocele embolisation in paediatric patients.Method: Retrospective cohort study of 14 years of endovascular Varicocele embolisation at a single-operator tertiary paediatric centre.Results: Eighty-four patients with a median age of 14 years (range 8-17 years) were identified. The varicoceles were predominantly of grade 1 or 2. 99% of patients had unilateral left-sided varicoceles. One patient had bilateral varicoceles. This study demonstrated that the technical success rate of endovascular embolisation is 94% and the clinical success rate is 98%. 84% reported feeling well in the immediate postprocedural period. 86% of cases reported excellent long-term progress. A small proportion (10%) experienced long-term discomfort or pain. There were no cases of relapse.Conclusion: Endovascular embolisation is a successful technique for the management of Varicocele in paediatric patients, with good immediate and long-term clinical outcomes. It has low recurrence rates.","PeriodicalId":16218,"journal":{"name":"Journal of Medical Imaging and Radiation Oncology","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144540466","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective is not only to quantify the effect but also to provide a framework for guiding clinical interpretation and reporting.Methods: A total of 235 oncologic PET/CT scans were retrospectively analysed. Patients were categorised into four groups based on extravasation severity: Grade 0 (no extravasation), Grade 1 (minimal), Grade 2 (moderate), and Grade 3 (severe). A visual grading system was developed and applied to classify image quality degradation. Mean SUVmax and SUVmean values were recorded from liver and mediastinal blood pool regions. Statistical comparisons were conducted using ANOVA and post hoc testing.Results: FDG extravasation was observed in 75 patients (31.9%). Among the 75 patients with extravasation, 43 were Grade 1 and 26 were Grade 2. Statistically significant increases were found in both liver and mediastinal SUV values in patients with Grade 1 and 2 extravasation compared to Grade 0 (p < 0.001 for all). For example, Liver SUVmax increased from 3.13 ± 0.44 (Grade 0) to 3.58 ± 0.50 (Grade 1), and MedSUVmean increased from 1.80 ± 0.31 (Grade 0) to 2.17 ± 0.40 (Grade 2), representing up to a 20.6% difference. Grade 3 cases did not show consistent trends.Conclusion: Low-to-moderate FDG extravasation can significantly alter reference SUV values. Incorporating extravasation grading into clinical reporting or normalising reference SUV values may enhance diagnostic consistency and minimise the need for repeat imaging.","PeriodicalId":16218,"journal":{"name":"Journal of Medical Imaging and Radiation Oncology","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144540517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to investigate the safety, feasibility and benefits of SBRT for PDAC in a clinical trial setting.Methods: SPAN-C was a single centre, single-arm, phase II clinical trial. Patients with locally advanced, borderline resectable, and metastatic PDAC suitable for high dose radiation were enrolled. Fiducial marker placement was mandated. Following induction chemotherapy, patients were treated with 40-45Gy in 5 fractions of external beam radiotherapy. Freedom from local failure at 12 months was the primary endpoint. Secondary endpoints included disease recurrence endpoints, acute and late toxicity, surgical outcomes, and palliative endpoints.Results: Thirty patients were enrolled. Median follow up of alive patients was 5 years (min 31 months). Twenty-six completed treatment as per protocol. Nine patients (34.6%) underwent a resection, 5 of whom had a R0 resection and 2 had a complete pathologic response. The 12-month freedom from local failure was 100% for the resected subgroup and 76.5% for the unresected subgroup. Seven patients (26.9%) had local recurrences, with 5 of these in the unresected group (29.4%). Median OS was 37.9 months for the resected subgroup and 10.7 months for the unresected subgroup. Three patients had grade 3 acute toxicity, and no patients had late high-grade toxicity.Conclusions: SBRT was safe and feasible with high rates of local control at 12 months and low rates of toxicity.

Recurrent patients were prospectively followed up according to the RANO criteria, aiming to investigate discrepancies between ADC and FA values in recurrent regions compared to normal control tissues prior to recurrence.Results: The rADC and rFA ratio approach 1 at a distance of 3 cm beyond the cavity. At the edge of the operative cavity and 2 cm beyond, the subtotal resection (STR) group exhibited higher ADC and rADC values compared to the gross total resection (GTR) group (p < 0.05). Similarly, FA and rFA values in the STR group were lower than those in the total resection group both at 1 cm beyond and 2 cm beyond (p < 0.05). Conventional MRI did not reveal any abnormalities prior to marginal or distant recurrence; however, the ADC value within this region was higher than that of control normal tissues (p = 0.023).Conclusions: The margins of GBM tumour invasion are typically not isotropic and could be > 2 cm and sometimes up to 3 cm. We recommend appropriately larger expansion of the target volume for patients with subtotal tumour resection. The utilisation of DTI in delineating the boundary of GBM's radiotherapy clinical target volume represents a promising avenue that holds potential to enhance precision and accuracy.","PeriodicalId":16218,"journal":{"name":"Journal of Medical Imaging and Radiation Oncology","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144266435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
