Differential outcomes at the Fellowship of the Royal College of Radiologists (FRCR) exams according to demographic and socioeconomic factors Clin. Radiol. (IF 2.1) Pub Date : 2024-07-14 J. Pakpoor, R. Ellis, Y. Al-Tawarah, I. Bhide, K. Muthuswamy, R. Khamar, S.A. Taylor, C. Chew
In the recent years, there has been an increase in the medical education literature showing that there are barriers to postgraduate exam success for some trainee groups compared to others. To date, there is little published data on whether these differences exist in UK radiology training. In this longitudinal cohort study, we aimed to evaluate the relationship between demographic and socioeconomic

Endovascular thrombectomy provides durable, symptomatic relief in iliocaval tumor thrombosis Clin. Radiol. (IF 2.1) Pub Date : 2024-07-10 I.N. Goronzy, A. Yearwood, E. Drews, T. Brundage, M. Ranade, J.M. Moriarty
Iliocaval venous tumor thrombus is a morbid condition associated with chronic venous stasis, lower extremity edema/pain, extensive thrombus burden and high mortality secondary to critical flow obstruction, intracardiac thrombus extension and tumor embolization. Typically resistant to medical therapy, management is primarily surgical, presenting challenges for medically complex patients with widespread

Mimics of primary ovarian cancer and primary peritoneal carcinomatosis – A pictorial review Clin. Radiol. (IF 2.1) Pub Date : 2024-07-09 B. Lawson, I. Rajendran, J. Smith, A. Shakur, V. Sadler, T.J. Sadler, H.C. Addley, S. Freeman
Numerous conditions can mimic ovarian malignancy. Identifying the origin of a pelvic mass or disseminated peritoneal abnormality on imaging is important to ensure that the patient receives optimal management by the appropriate clinical team.

Comparative analysis of three-dimensional and two-dimensional models for predicting the malignancy probability of subsolid nodules Clin. Radiol. (IF 2.1) Pub Date : 2024-07-09 Y.-M. Hui, Y. Guo, B. Li, Y.-Q. Meng, H.-M. Feng, Z.-P. Su, M.-Z. Lin, Y.-Z. Chen, Z.-Z. Zheng, H.-T. Li
To construct three-dimensional (3D) and two-dimensional (2D) models to predict the malignancy probability of subsolid nodules (SSNs) and compare their effectiveness. A total of 371 SSNs from 332 patients, collected between January 2020 and January 2024, were included in the study. The SSNs were divided into a training set for constructing the models and a test set for validating the models. Models

Low energy virtual monochromatic CT with deep learning image reconstruction to improve delineation of endoleaks Clin. Radiol. (IF 2.1) Pub Date : 2024-07-09 T. Higashigawa, Y. Ichikawa, K. Nakajima, T. Kobayashi, K. Domae, A. Yamazaki, N. Kato, T. Ouchi, H. Kato, H. Sakuma
This study aimed to investigate the utility of low-energy virtual monochromatic imaging (VMI) combined with deep-learning image reconstruction (DLIR) in improving the delineation of endoleaks (ELs) after endovascular aortic repair (EVAR) in contrast-enhanced dual-energy CT (DECT). A total of 61 consecutive patients (mean age, 77 years; 46 men) after EVAR who underwent contrast-enhanced DECT were enrolled

Impact of non-invasive post-mortem micro-CT imaging on a fetal autopsy service: a single centre retrospective study Clin. Radiol. (IF 2.1) Pub Date : 2024-07-06 I.C. Simcock, O.J. Arthurs, J.C. Hutchinson, N.J. Sebire, T.S. Jacques, T. Sekar, S.C. Shelmerdine, GOSH Pathology, D. Alvarez, V. Lee, E. Yates, E. Smith, L. McMinn, L. Ward, S. Levine, L. Palm, A. Devdas, A. Kumar, A. Merve
To evaluate the impact of a new, less-invasive micro-computed tomography (CT) service on autopsy service provision. We recorded parental consent, type of autopsy performed, autopsy reporting times and time taken for the body to be released from the mortuary. A retrospective, single-centre case series was conducted for all perinatal deaths since the introduction of our micro-CT service in 2016, with
