To investigate the diagnostic performance of an automatic pipeline for detection of hydronephrosis on kidney's parenchyma on unenhanced low-dose CT of the abdomen. This retrospective study included 95 patients with confirmed unilateral hydronephrosis in an unenhanced low-dose CT of the abdomen. Data were split into training (n = 67) and test (n = 28) cohorts. Both kidneys for each case were included

68Ga‐DOTATATE PET/CT: How is it reliable in imaging of cases having clinical suspicion of insulinomas? Eur. J. Radiol. (IF 3.2) Pub Date : 2024-08-08 Mostafa M. Abdelkawi, Marwa A. Romeih, Merhan A. Nasr, Eman A. NasrElDin
This retrospective study evaluates the value of Ga‐DOTATATE PET/CT in the diagnosis and localization of insulinomas, whether sporadic, malignant or MEN‐1 associated insulinoma. The study included 43 patients, having clinical (symptomatic hypoglycemia) and/or laboratory suspicion of having insulinoma (72 h fasting test with serum insulin ≥18 pmol/L), with available pre-operative Ga‐DOTATATE PET/CT and

An exploration of radiological signs in post-intervention liver complications Eur. J. Radiol. (IF 3.2) Pub Date : 2024-08-05 Faezeh Khorasanizadeh, Narges Azizi, Roberto Cannella, Giuseppe Brancatelli
The advent and progression of radiological techniques in the past few decades have revolutionized the diagnostic and therapeutic landscape for liver diseases. These minimally invasive interventions, ranging from biopsies to complex therapeutic procedures like transjugular intrahepatic portosystemic shunt placement and transarterial embolization, offer substantial benefits for the treatment of patients

The “Hungry Judge” effect on prostate MRI reporting: Chronobiological trends from 35’004 radiologist interpretations Eur. J. Radiol. (IF 3.2) Pub Date : 2024-08-05 Anton S. Becker, Sungmin Woo, Doris Leithner, Angela Tong, Marius E. Mayerhoefer, H. Alberto Vargas
To investigate the associations between the hour of the day and Prostate Imaging–Reporting and Data System (PI-RADS) scores assigned by radiologists in prostate MRI reports. Retrospective single-center collection of prostate MRI reports over an 8-year period. Mean PI-RADS scores assigned between 0800 and 1800 h were examined with a regression model. A total of 35′004 prostate MRI interpretations by

Impact of different concentration iodinated contrast media on pain and comfort in abdominal computed tomography Eur. J. Radiol. (IF 3.2) Pub Date : 2024-08-05 Yan-Xia Sun, Jing Shang, Yong Cui, Ke-Jin Zhang, Xiao-Ting Li, Dan-Ni Li, Xiao-Lei Gu, Xiao-Yu Tian, Nan Sun, Lan Zhang, Miao-Ning You, Xiao-Yan Zhang, Ying-Shi Sun
To investigate whether high concentration iodinated contrast media (CM), compared with low concentration CM, could reduce pain and discomfort levels in patients who had level II and III venous conditions. This prospective, single-center study enrolled patients who had level II and III venous conditions and underwent abdominal contrast-enhanced CT scan between July 2021 and February 2022. The venous

Deep learning reconstruction for optimized bone assessment in zero echo time MR imaging of the knee Eur. J. Radiol. (IF 3.2) Pub Date : 2024-08-04 Falko Ensle, Frederik Abel, Maelene Lohezic, Carina Obermüller, Roman Guggenberger
To evaluate the impact of deep learning-based reconstruction (DLRecon) on bone assessment in zero echo-time (ZTE) MRI of the knee at 1.5 Tesla. This retrospective study included 48 consecutive exams of 46 patients (23 females) who underwent clinically indicated knee MRI at 1.5 Tesla. Standard imaging protocol comprised a sagittal prescribed, isotropic ZTE sequence. ZTE image reconstruction was performed

Predicting efficacy of neoadjuvant chemotherapy in breast cancer patients with synthetic magnetic resonance imaging method MAGiC: An observational cohort study Eur. J. Radiol. (IF 3.2) Pub Date : 2024-08-03 Ting Zhan, Chenghao Yi, Yuanyuan Lang
MAGnetic resonance Imaging Compilation (MAGiC) is typical method of synthetic magnetic resonance imaging (MRI). The present aimed to investigate the role of MAGiC parameters of relaxation time (T1), transverse relaxation time (T2) and proton density (PD) to predict the treatment efficacy of breast cancer patients after neoadjuvant chemotherapy (NAC). The present prospective cohort study enrolled 120

To evaluate the performance of artificial intelligence (AI) in the preoperative detection of lung metastases on CT. Patients who underwent lung metastasectomy in our institution between 2016 and 2020 were enrolled, their preoperative CT reports having been performed before an AI solution (Veye Lung Nodules, version 3.9.2, Aidence) became available as a second reader in our department. A total of 167
