Radiomics under 2D regions, 3D regions, and peritumoral regions reveal tumor heterogeneity in non-small cell lung cancer: a multicenter study
La radiologia medica - - 2023
Lung cancer has significant genetic and phenotypic heterogeneity, leading to poor prognosis. Radiomic features have emerged as promising predictors of the tumor phenotype. However, the role of underlying information surrounding the cancer remains unclear. We conducted a retrospective study of 508 patients with NSCLC from three institutions. Radiomics models were built using features from six tumor......
Stent graft in TIPS: technical and procedural aspects
La radiologia medica - Tập 111 - Trang 709-723 - 2006
Transjugular intrahepatic portosystemic shunt (TIPS) is a nonoperative therapeutic option for the management of portal hypertension, variceal bleeding, recurrent ascites, Budd–Chiari syndrome. In view of the many issues surrounding the use of TIPS, in 1994 the US National Digestive Diseases Advisory Board convened a scientific conference to review the current data available and to establish the in......
Intradiscal ozone therapy: fluoroscopic guidance reduces operative time in comparison with CT guidance in patients with lumbar disc herniation
La radiologia medica - Tập 127 - Trang 526-533 - 2022
To compare clinical success and operative time for percutaneous intradiscal ozone therapy in patients with lumbar disc herniation using fluoroscopic guidance versus computed tomography (CT). During the year 2019, 68 percutaneous single-level intradiscal ozone therapies were performed on patients complaining of low back pain and/or sciatica due to lumbar disc herniation, using fluoroscopic or conve......
Critical issues in radiology requests and reports
La radiologia medica - Tập 116 - Trang 152-162 - 2010
This study evaluated the appropriateness and accuracy of 500 radiology requests and their matched reports in order to identify recurring errors in both areas. A randomly chosen sample consisting of 167 computed tomography (CT), 166 ultrasonography (US) and 167 radiographic examinations were collected and analysed according to national referral guidelines and to the principles of justification and ......
Apparent diffusion coefficient value of hepatic fibrosis and inflammation in children with chronic hepatitis
La radiologia medica - Tập 119 - Trang 903-909 - 2014
This study was done to prospectively evaluate the usefulness of apparent diffusion coefficient (ADC) in the diagnosis and grading of hepatic fibrosis and inflammation in children with chronic hepatitis. Institutional Review Board approval was obtained. This prospective study was carried out on 50 children with chronic hepatitis (mean age 8.3 ± 3.2 years; 33 boys and 17 girls) and 20 age- and sex-m......
Assessment of salivary gland tumors using MRI and CT: impact of experience on diagnostic accuracy
La radiologia medica - - 2017
To analyze the accuracy of radiological diagnosis in MRI and CT studies of salivary gland tumors depending on the radiologist’s experience. Three radiologists with differing experience (R1 > 20, R2 > 11, and R3 > 7 years, respectively) retrospectively reviewed 128 cases (116 MRI, 12 CT studies) with suspected salivary gland tumors regarding dignity and classification using histopathology as a refe......
Impact of DWI and ADC values in Ovarian-Adnexal Reporting and Data System (O-RADS) MRI score
La radiologia medica - Tập 128 - Trang 565-577 - 2023
Introduce DWI and quantitative ADC evaluation in O-RADS MRI system and observe how diagnostic performance changes. Assess its validity and reproducibility between readers with different experience in female pelvic imaging. Finally, evaluate any correlation between ADC value and histotype in malignant lesions.
In total, 173 patients with 213 indeterminate adnexal masses (AMs) on ultrasound were su......
Image-based artificial intelligence for the prediction of pathological complete response to neoadjuvant chemoradiotherapy in patients with rectal cancer: a systematic review and meta-analysis
La radiologia medica - - 2024
Artificial intelligence (AI) holds enormous potential for noninvasively identifying patients with rectal cancer who could achieve pathological complete response (pCR) following neoadjuvant chemoradiotherapy (nCRT). We aimed to conduct a meta-analysis to summarize the diagnostic performance of image-based AI models for predicting pCR to nCRT in patients with rectal cancer. This study followed the P......
