The diagnostic role of ultrasonography, computed tomography, magnetic resonance imaging, positron emission tomography/computed tomography, and real-time elastography in the differentiation of benign and malignant salivary gland tumors: a meta-analysis

ConclusionBased on the results of the meta-analysis, MRI may be the first choice for the differential diagnosis of benign and malignant salivary gland tumors for its relatively high diagnostic value. PET/CT tends to have greater accuracy than CT. Ultrasonography and RTE may help achieve better diagnostic outcomes if they are used in conjunction.

CONCLUSIONS: Functional imaging represents an attractive and non-invasive modality to assess complex biological phenomena in solid tumors. Larger tumor volume and increasing hypoxia emerged as putative prognostic imaging biomarkers in HNSCC. PMID: 31496204 [PubMed - as supplied by publisher]

AbstractBackground.In endometrial carcinoma (EC), preoperative classification is based on histopathological criteria, with only moderate diagnostic performance for the risk of lymph node metastasis (LNM). So far, existing molecular classification systems have not been evaluated for prediction of LNM. Optimized use of clinical biomarkers as recommended by international guidelines might be a first step to improve tailored treatment, awaiting future molecular biomarkers.Aim.To determine the diagnostic accuracy of preoperative clinical biomarkers for the prediction of LNM in endometrial cancer.Methods.A systematic review was p...

Conclusion We ascribe the incorrect diagnosis to insufficient understanding on imaging manifestations of brain neoplasm as well as clinical features of parasitosis. Thus, we review the MRI, FDG-PET-CT, MRS and DTI data of this case according to the timeline, refer to relevant studies, and point out the pitfalls. With a long course of slowly progressing, this was a rare case of secondary glioblastoma with the absence of isocitrate dehydrogenase 1 (IDH1) gene mutation.

Authors: Shao T, Josephson L, Liang SH Abstract Nonalcoholic fatty liver disease (NAFLD) is a significant public health challenge afflicting approximately 1 billion individuals both in the Western world and in the East world. While liver biopsy is considered as gold standard in the diagnosis and staging of liver fibrosis, noninvasive imaging technologies, including ultrasonography, computed tomography, single-photon emission computed tomography (SPECT), magnetic resonance imaging, and positron emission tomography (PET) could offer more sensitive, comprehensive, and quantitative measurement for NAFLD. In this review...

Our preference is to complete systemic staging to identify evidence of any other metastatic disease and repeat brain imaging workup with computed tomography (CT) and magnetic resonance imaging for hemorrhagic infarct versus hemorrhagic metastasis.1 If CT of the chest/abdomen/pelvis or positron emission tomography/CT is negative, then in the absence of pathology, our preference would be a neurosurgical consult for pathology. Based on the Patchell et  al study, the potential for nonmalignant pathology could be 11%.

Conclusions No clinically significant brain injury (requiring intervention) was seen in this cohort. These findings support delaying imaging in neurologically intact children to obtain MRI after hospital admission, thus, limiting radiation exposure.

AbstractRadiomics is an emerging field which extracts quantitative radiology data from medical images and explores their correlation with clinical outcomes in a non-invasive manner. This review aims to assess whether radiomics is a useful and reproducible method for clinical management of hepatocellular carcinoma (HCC) by reviewing the strengths and weaknesses of current radiomics literature pertaining specifically to HCC. From an initial set of 48 articles recovered through database searches, 23 articles were retained to be included in this review after full screening. Among these 23 studies, 7 used a radiomics approach i...
