Description

The proposed radiomics signature predicted the correct histology with 94.5% accuracy (76.4% accuracy in 10-times leave group out cross-validation method).

To define and validate a radiomics model to predict histological grade in patients affected by PDAC The various species of Aspergillus are ubiquitous in the environment, and usually do not cause any human pathology, provided the lungs are structurally normal and the host immunity is intact. If either of these is abnormal, then there is the possibility that this otherwise benign fungus may cause pathology. Role of immunity in aspergillosis Radiomics developed with a combination of nonenhanced and portal venous phases shows good discrimination and calibration of preoperatively predicting tumour grading in patients with grade 1/2 NF-pNETs. Despite the above limitations, radiomics could potentially have an important role in providing reliable risk stratification (for both outcomes or complications), facilitating surgical choices, predicting clinical response after treatments, allowing differential diagnosis between cancer and other benign pancreatic abnormalities and predicting histological examination, disease differentiation grade or specific gene mutations.

To identify patients affected by PDCA against patients with healthy pancreas using a CT-based radiomics model The infection is primarily caused by the aerobic gram-negative bacillus Legionella pneumophila (thought be responsible for around 80% of cases) and, to a lesser extent, by organisms such as A novel radiomics-based formula was developed and validated for predicting POPF in patients who underwent pancreaticoduodenectomy.

Radiographics. 2001;21(4):825-37. doi:10.1148/radiographics.21.4.g01jl03825 both axonal subtypes are thought to be due to antibodies to gangliosides which result in macrophages invading the axons at the nodes of Ranvier 3

CT-based features were found able to distinguish PC from normal pancreatic tissue 23, 28 and to detect cancer in the context of intraductal papillary mucinous neoplasm (IPMN) 27, 30; CT- and PET-CT-based radiomics could discriminate PC from pancreatitis, 24 – 26, 31, 32 while MRI was able to discriminate pancreatic neuroendocrine tumours (pNETs) from solid pseudopapillary tumours in one study. 29 Six studies (10.7%) analyzed technical feasibility and reproducibility aspects of radiomics analysis. Yamashita et al. 33 demonstrated that the variation between contrast-enhanced CT scans (e.g. scanner model, pixel spacing and contrast administration rate) affects radiomic feature reproducibility more significantly than the variation in segmentation. Mori et al. 34 confirmed the minimal impact of delineation uncertainty of pancreatic neuroendocrine neoplasms (panNEN) on CT radiomics features extraction. Plautz et al. 35 observed statistically significant changes over the radiotherapy course time in patients’ radiomics feature values, describing interesting delta-radiomics applications also in PC. Chu et al. 36 compared the diagnostic performances between a commercial and an in-house radiomic software. Loi et al. 37 evaluated the impact of interpolation and discretization on the robustness of radiomics features. The reproducibility of radiomics features in patients affected by pNETs was analyzed by Gruzdev et al. 38 Section of Scienze Radiologiche, Department of Medicine and Surgery (DiMeC), University of Parma, Parma, Italy.

Imaging features can be variable although changes are often described as multifocal and bilateral. There may be a middle and lower zone predominance 5.

RF extracted from clinical CT images is associated with genotype, the number of altered genes and stromal content in PDAC.Zmeili O & Soubani A. Pulmonary Aspergillosis: A Clinical Update. QJM. 2007;100(6):317-34. doi:10.1093/qjmed/hcm035
