The purpose of this part the meta-analysis was to summarize data regarding associations between minimum apparent diffusion coefficient (ADCmin) and KI 67 in different tumors. MEDLINE library screened for ADCmin tumors up April 2017. Overall, 23 studies with 944 patients were identified. Associations ADC analyzed by Spearman's correlation coefficient. pooled all included ρ = -0.47. In detail, coefficients separate as follows: cerebral lymphoma: -0.61 (95% CI [-0.82; -0.41]); cervical cancer:...

Pre-surgical diffusion weighted imaging (DWI) is increasingly important in the context of thyroid cancer for identification optimal treatment strategy. It has exemplarily been shown that DWI at 3T can distinguish undifferentiated from well-differentiated carcinoma, which decisive implications magnitude surgery. This study used histogram analysis whole tumor apparent coefficient (ADC) maps. The primary aim was to discriminate carcinomas had already gained capacity metastasize lymphatically...

Numerous studies have analyzed associations between apparent diffusion coefficient (ADC) and histopathological features such as Ki-67 proliferation index in breast cancer (BC), with mixed results. The purpose of this study was to perform a multicenter analysis determine relationships ADC expression tumor grade BC.For study, data from six centers were acquired. sample comprises 870 patients (all female; mean age, 52.6 ± 10.8 years). In every case, magnetic resonance imaging diffusion-weighted...

Dynamic contrast-enhanced magnetic resonance imaging (DCE MRI) can characterize perfusion and vascularization of tissues. DCE MRI parameters differentiate between malignant benign lesions predict tumor grading. The purpose this study was to correlate findings various histopathological in head neck squamous cell carcinoma (HNSCC).Sixteen patients with histologically proven HNSCC (11 cases primary tumors 5 local recurrence) were included the study. performed all following estimated: Ktrans,...

Abstract Objective The Node-RADS classification was recently published as a system to better characterize lymph nodes in oncological imaging. present analysis investigated the diagnostic benefit of staging computed tomography (CT) images categorize and stage patients with colon cancer. Materials methods All were surgically resected histopathological analyzed. scored accordance by two experienced radiologists. Interreader variability assessed Cohen’s kappa analysis, discrimination performed...

OBJECT: Thyroid cancer represents the most frequent malignancy of endocrine system with an increasing incidence worldwide. Novel imaging techniques are able to further characterize tumors and even predict histopathology features. Texture analysis is emergent technique extract extensive data from radiology images. The present study was therefore conducted identify possible associations between texture parameters in thyroid cancer. METHODS: radiological database retrospectively reviewed for...

Abstract Background Texture analysis derived from computed tomography (CT) can provide clinically relevant imaging biomarkers. Node-RADS is a recently proposed classification to categorize lymph nodes in radiological images. The present study sought investigate the diagnostic abilities of CT texture and discriminate benign malignant mediastinal patients with lung cancer. Methods Ninety-one ( n = 32 females, 35%) mean age 64.8 ± 10.8 years were included this retrospective study. was performed...

Low skeletal muscle mass (LSMM) and visceral fat areas can be assessed by cross-sectional images. These parameters are associated with several clinically relevant factors in various disorders predictive prognostic implications. Our aim was to establish the effect of computed tomography (CT)-defined LSMM on unfavourable outcomes in-hospital mortality coronavirus disease 2019 (COVID-19) patients based a large patient sample.MEDLINE library, Cochrane, Scopus databases were screened for...

The aim of this study was to compare microwave ablation (MWA) with and without prior placement an intra-arterial catheter for the purpose application contrast medium (CM). 148 patients (45 female, 65.1 ± 14.9 years) liver tumors who underwent CT-guided MWA were included. Of these, 25 had IA placed in hepatic artery. 37 planning imaging CM. A total 86 received a standard dose 80 mL intravenous (IV) CM scans. (n = 25) 10 29 contrast-enhanced scans PV phase control needle positioning after IV...

Abstract Objectives Body composition assessment includes the parameter skeletal muscle mass, subcutaneous and visceral adipose tissue (SAT VAT). The purpose of this study was to elucidate associations body parameters with mortality in patients acute bleeding undergoing transarterial embolization (TAE). Methods A mixed cohort from 2018 2022 requiring treatment a TAE retrospectively evaluated. In every case, triphasic computed tomography (CT) diagnose source used calculate parameters. Results...

Texture analysis has the potential to deliver quantitative imaging markers. Patients receiving computed tomography (CT)-guided percutaneous bone biopsies could be characterized using texture derived from CT. Especially for breast cancer (BC) patients, it crucial better predict outcome of biopsy reflect immunohistochemistry status tumor. The present study examined relationship between features and outcomes in patients with BC CT-guided biopsies. This is based on a retrospective analysis....

Abstract Objective and background Hyperspectral imaging (HSI) is an innovative, noninvasive technique that assesses tissue organ perfusion oxygenation. This study aimed to evaluate HSI as a predictive tool for early postoperative graft function long-term outcomes in living donor (LD) deceased (DD) kidney transplantation (KT). Patients methods of allograft parenchyma from 19 LD 51 DD kidneys was obtained intraoperatively 15 minutes after reperfusion. Using the dedicated TIVITA Tissue System,...
