Fusion imaging versus ultrasound-guided percutaneous thermal ablation of liver cancer: a meta-analysis. Acta Radiol. (IF 1.3) Pub Date : 2023-07-28 Yangang Sheng,Xueke Sun,Hongmei Sun,Jinyan Qi,Hua Li,Jiankui Luan,Deyin Zhai
BACKGROUND Ultrasound-guided percutaneous thermal ablation has become an alternative treatment for small hepatocellular carcinoma (HCC). Recent evidence suggests that fusion imaging (FI) may improve the feasibility and efficacy of thermal ablation for HCC, while the clinical evidence remains limited. PURPOSE To compare FI versus ultrasound-guided thermal ablation for HCC. MATERIAL AND METHODS Relevant

A novel method of measuring proptosis with computed tomography. Acta Radiol. (IF 1.3) Pub Date : 2023-07-27 Rou Sun,Ziqing Yin,Lunhao Li,Huifang Zhou,Xuefei Song,Yinwei Li
BACKGROUND Computed tomography (CT) can avoid interference factors and has been imported into some software to measure proptosis clinically as the golden standard. PURPOSE To establish a new method for semi-automatically measuring the proptosis on CT and evaluate its accuracy and reproducibility. MATERIAL AND METHODS A total of 50 orbital CT images were collected of healthy individuals, 25 patients

Extended and weightbearing wrist 3-T MRI using a novel harness and flexible 24-channel glove coil to evaluate carpal kinematics: a pilot study in 10 volunteers. Acta Radiol. (IF 1.3) Pub Date : 2023-07-20 Bili Wang,Jerzy Walczyk,Mohammad Ahmed,Stuart Elkowitz,Steven Daniels,Ryan Brown,Christopher J Burke
BACKGROUND Wrist pain in the extended or extended weightbearing positions may be incompletely evaluated using standard magnetic resonance imaging (MRI) with standard rigid clamshell coils in the neutral position. PURPOSE To evaluate a flexible 24-channel glove coil and harness when imaging the wrist in neutral, dorsally extended, and weightbearing positions. MATERIAL AND METHODS Ten wrists in 10 asymptomatic

Trade-off between the radiation parameters and image quality using iterative reconstruction techniques in head computed tomography: a phantom study. Acta Radiol. (IF 1.3) Pub Date : 2023-07-19 Elīza Lāce,Reza Mohammadian,Ainārs Āboltiņš,Dāvis Sosārs,Ilze Apine
BACKGROUND Iterative reconstruction techniques (IRTs) are commonly used in computed tomography (CT) and help to reduce image noise. PURPOSE To determine the minimum radiation dose while preserving image quality in head CT using IRTs. MATERIAL AND METHODS The anthropomorphic phantom was used to scan nine head CT image series with varied radiation parameters. CT dose parameters, including volume CT dose

Significance of marginal vessels in differentiating peripheral small-cell lung cancer and benign lung tumor. Acta Radiol. (IF 1.3) Pub Date : 2023-07-18 Xiao-Chuan Zhang,Fa-Jin Lv,Bin-Jie Fu,Zhang-Rui Liang,Zhi-Gang Chu
BACKGROUND Some peripheral small cell lung cancers (pSCLCs) and benign lung tumors (pBLTs) have similar morphological features but different treatment and prognosis. PURPOSE To determine the significance of marginal vessels in differentiating pSCLCs and pBLTs. MATERIAL AND METHODS A total of 57 and 95 patients with pathological confirmed nodular (≤3 cm) pSCLC and pBLT with similar morphological features

MRI reliability in pediatric abdominal lymph node metastases? Acta Radiol. (IF 1.3) Pub Date : 2023-07-18 Sabriye Gülçin Bozbeyoğlu,Umut Perçem Orhan Söylemez,Nesrin Gündüz
BACKGROUND Although positron emission tomography-computed tomography (PET-CT) is an effective imaging method used in the detection of lymph node metastases, repeated imaging increases X-ray exposure, especially in pediatric patients. Magnetic resonance imaging (MRI) may detect abdominal lymph nodes and provide subtle anatomic detail, and functional information without radiation. PURPOSE To evaluate

Left atrium volume and ventricular volume ratio algorithm as indication of pulmonary hypertension etiology. Acta Radiol. (IF 1.3) Pub Date : 2023-07-13 Yoav Granot,Tomer Ziv-Baran,Shlomo Berliner,Yan Topilsky,Galit Aviram
BACKGROUND Pressure overload of the right heart (pulmonary hypertension [PH]) can be an acute or a chronic process with various pathophysiologic changes affecting the dimensions of the heart chambers. The automatic four-chamber volumetric analysis tool is now available to measure the volume of the cardiac chambers in patients undergoing a computed tomography pulmonary angiogram (CTPA). PURPOSE To characterize

Pectoralis muscle predicts distant metastases in breast cancer by deep learning radiomics. Acta Radiol. (IF 1.3) Pub Date : 2023-07-12 Shidi Miao,Yunfei An,Pingping Liu,Shikai Mu,Wenjin Zhou,Haobo Jia,Wenjuan Huang,Jing Li,Ruitao Wang
BACKGROUND Sarcopenia is associated with a poor prognosis in patients with breast cancer (BC). Currently, there are few quantitative assessments carried out between muscle biomarkers and distant metastasis using existing methods. PURPOSE To assess the predictive value of the pectoralis muscle for BC distant metastasis, we developed a deep learning radiomics nomogram model (DLR-N) in this study. MATERIAL

Is Likert better than PI-RADS at predicting prostate cancer on MRI and can a mathematical algorithm achieve similar results? Acta Radiol. (IF 1.3) Pub Date : 2023-07-12 William Stevens,Catherine Parchment-Smith,Ese Adiotomre,Oliver Hulson,Atif Khan,Philip Melling,Sacha Pierre,Jonathan Smith
BACKGROUND Prostate Imaging Reporting & Data System (PI-RADS) is an internationally recognized system to quantify risk of prostate cancer on magnetic resonance imaging (MRI). However, studies have suggested methods to improve predictive accuracy. PURPOSE To assess two different methods that aim to improve the accuracy of PI-RADS scores: a subjective Likert score given by experienced reporters, and
