Ultrasound features of benign paediatric lumps: radiology–pathology correlation Clin. Radiol. (IF 2.6) Pub Date : 2024-01-20 R. Patel, A. Shames, J. Sarkodieh
Ultrasonography is an appropriate first-line imaging technique for the characterisation of paediatric lumps, given its relative accessibility and absence of radiation exposure. Together with a thorough history and examination, ultrasonography can help to distinguish benign lesions from malignancy. It can also aid further characterisation of benign lesions to inform onward investigation and management

Intravoxel incoherent motion diffusion-weighted imaging of solitary pulmonary lesions: initial study with gradient- and spin-echo sequences Clin. Radiol. (IF 2.6) Pub Date : 2024-01-19 M. Yin, Guanjie Cao, S. Lv, Z. Sun, M. Li, H. Wang, X. Yue
To evaluate the feasibility and image quality of intravoxel incoherent motion diffusion-weighted imaging (IVIM) using gradient- and spin-echo (GRASE) in solitary pulmonary lesions (SPLs) compared to echo planar imaging (EPI) and turbo spin-echo (TSE) at 3 T. Forty-two patients with SPLs underwent lung magnetic resonance imaging (MRI) using TSE-IVIM, GRASE-IVIM, and EPI-IVIM at 3 T. Signal ratio (SR)

Early change in apparent diffusion coefficient as a predictor of response to neoadjuvant androgen deprivation and external beam radiation therapy for intermediate- to high-risk prostate cancer Clin. Radiol. (IF 2.6) Pub Date : 2024-01-19 F.B. Franco, J.E. Leeman, A. Fedorov, M. Vangel, F.M. Fennessy
To determine the role of serial apparent diffusion coefficient (ADC) as a biomarker for response to neoadjuvant androgen deprivation therapy (nADT) followed by external beam radiation therapy (EBRT) in intermediate- to high-risk prostate cancer (PCa) patients. This Health Insurance Portability and Accountability Act (HIPAA)-compliant, institutional review board (IRB)-approved prospective study included

Frequency and classification of addenda in paediatric neuroradiological reports as part of quality assurance Clin. Radiol. (IF 2.6) Pub Date : 2024-01-18 S.S.B. Venkatakrishna, A. Ghosh, P. Sharma, M. Miranda-Schaeubinger, A.V. Prakash, L. Addisu, R.W. Sze, S. Andronikou
To determine the frequency and classification of addenda seen in paediatric brain magnetic resonance imaging (MRI) reports. A retrospective review of the addenda of brain MRI reports from a large tertiary children's hospital was undertaken between January 2013 to December 2021 and a subset of above radiology reports was used to classify addenda over 6-month periods, October to March, spanning 2018

Effect of X-ray tube on image quality and pancreatic ductal adenocarcinoma conspicuity in pancreatic protocol dual-energy CT Clin. Radiol. (IF 2.6) Pub Date : 2024-01-18 Y. Noda, Y. Takai, T. Suto, N. Yamada, T. Mori, N. Kawai, T. Kaga, F. Hyodo, H. Kato, M. Matsuo
To compare the radiation dose, image quality, and conspicuity of pancreatic ductal adenocarcinoma (PDAC) in pancreatic protocol dual-energy computed tomography (CT) between two X-ray tubes mounted in the same CT machine. This retrospective study comprised 80 patients (median age, 73 years; 45 men) who underwent pancreatic protocol dual-energy CT from January 2019 to March 2022 using either old (Group

Flexed elbow, abducted shoulder, forearm supinated (FABS) reconstruction from three-dimensional elbow MRI: diagnostic performance assessment in biceps head anatomy and pathology Clin. Radiol. (IF 2.6) Pub Date : 2024-01-13 V.A. Aggarwal, U. Thakur, F.D. Silva, G. Ray, C. Weinschenk, M. Gandy, Y. Xi, A. Chhabra
To determine inter-reader analysis and diagnostic performance on digitally reconstructed virtual flexed, abducted, supinated (FABS) imaging from three-dimensional (3D) isotropic elbow magnetic resonance imaging (MRI). Six musculoskeletal radiologists independently evaluated elbow MRI images with virtual FABS reconstructions, blinded to clinical findings and final diagnoses. Each radiologist recorded
