AbstractAbstract
[en] Highlights: • Glioblastomas and metastases are the most frequent brain tumors in adult population. • Even with nowadays advanced MR techniques performed, diagnostic uncertainty remains. • Fractal and texture MRI analyses were evaluated in differentiating these tumors. • Texture features have proven to be more powerful in differentiation. • T2W images yielded the maximum different parameters, followed by CET1 and SWI. - Abstract: PurposeGlioblastomas (GBM) and metastases are the most frequent malignant brain tumors in the adult population. Their presentation on conventional MRI is quite similar, but treatment strategy and prognosis are substantially different. Even with advanced MR techniques, in some cases diagnostic uncertainty remains. The main objective of this study was to determine whether fractal, texture, or both MR image analyses could aid in differentiating glioblastoma from solitary brain metastasis.

AbstractAbstract
[en] Highlights: • ADC shows negative correlation with SUV and decreases in metastatic tumours. • TLG and MTV/ADCmin ratio have high predictive value for metastasis and advanced TNM stage tumours. • Patients with larger MTV/ADCmin have a shorter PFS and OS. - Abstract: PurposeTo correlate the clinical stage and prognosis of oesophageal squamous cell carcinoma (SCC) using the imaging biomarkers from integrated positron emission tomography (PET)/magnetic resonance imaging (MRI).

AbstractAbstract
[en] Highlights: • Interreader agreement for CEUS LI-RADS categories and major features is substantial. • CEUS LI-RADS is a promising standardized categorization system for high-risk patients. • The combination of two or three LR-M features may improve the true-negative classification of HCC diagnosis. - Abstract: PurposeThis study explored the interreader agreement and diagnostic performance of contrast-enhanced ultrasound liver imaging reporting and data system (CEUS LI-RADS).

AbstractAbstract
[en] Highlights: • Tumor stroma ratio and dominant stroma type were independent prognostic factors of solid tumors. • D and f values showed significant differences according to TSR of breast cancer. • The D value was lower in collagen dominant type than in fibroblast dominant or lymphocyte dominant type of breast cancer. - Abstract: PurposeTo determine whether imaging parameters derived from intravoxel incoherent motion (IVIM) diffusion weighted imaging (DWI) vary according to tumor-stroma ratio(TSR) or dominant stroma type of breast cancer.

AbstractAbstract
[en] Highlights: • PET parameters and CT-radiomics both have capacity on differentiating lung lesions. • Performance of PET parameters and CT-radiomics do not show significant difference. • The features of SurfaceVolumeRatio and SUVpeak were found as potential biomarker. • SurfaceVolumeRatio differentiates granulomatous lesion from inflammatory pseudotumor. - Abstract: PurposeThe study is to explore potential features and develop classification models for distinguishing benign and malignant lung lesions based on CT-radiomics features and PET metabolic parameters extracted from PET/CT images.

AbstractAbstract
[en] A prospective study of the diagnostic yield of ultrasound (US) and ERCP was made on a continuous series of 424 patients. Technical failures were slightly more frequent with US (11%) than with ERCP (8%), while US proved more accurate than ERCP in the diagnosis of focal hepatic disease -94% of correct diagnoses versus 41% (n=17). In diffuse hepatic disease (n=63) the accuracy of both methods was the same -87% of correct diagnoses with US, 83% with ERCP. US had better performances (91%), while ERCP was more accurate in the diagnosis of common duct lithiasis or tumor (98% for ERCP, 36% for US). Although ERCP has a better diagnostic yield for pancreatic diseases (92% to 100% of correct diagnoses according to the lesions) associate complications, such as pseudo-cysts, abscess formation and extravasations are better demonstrated by US (95% of correct diagnoses versus 73%). The two methods thus prove to be complementary. (orig.)

AbstractAbstract
[en] The ultrasound images of liver tumours of 28 patients were compared with their vascular images on arteriography. In addition, 17 of these patients underwent contrast computed tomography examinations, and a comparison was made between the markedly contrastenhanced tumour areas and their ultrasound images. No clear correlation was found between the echogenicity of the tumours and the vascularity seen in arteriography and/or computed tomography. The hypervascular and hypo- or avascular tumour areas could be markedly or minimally echogenic or show only diffuse alteration in the echo architecture. (orig.)
