It is extremely important to make a clear diagnosis and timely treatment of endocrine tumors. Machine learning includes radiomics, which has long been utilized in clinical cancer research. Radiomics refers to the extraction of valuable information by analyzing a large amount of standard data with high-throughput medical images mainly including computed tomography, positron emission tomography, magnetic resonance imaging, and ultrasound. With the quantitative imaging analysis and ...

CONCLUSIONS: Compared to systematic TRUS biopsy, implementation of prebiopsy prostate MRI and FB allows for safe and feasible SBRT in patients with significantly larger prostate volumes without increasing SIB cancer-directed treatment volumes, oncologic outcomes, quality of life measures, or treatment-related toxicities.PMID:34657654

CONCLUSIONS: In the clinical pathway for the diagnosis of hepatocellular carcinoma in adults with chronic liver disease, CT has roles as a confirmatory test for hepatocellular carcinoma lesions, and for staging assessment. We found that using CT in detecting hepatocellular carcinoma of any size and stage, 22.5% of people with hepatocellular carcinoma would be missed, and 8.7% of people without hepatocellular carcinoma would be unnecessarily treated. For resectable hepatocellular carcinoma, we found that 28.6% of people with resectable hepatocellular carcinoma would improperly not be resected, while 8% of people without hep...

Online ahead of print.ABSTRACTProstate magnetic resonance imaging (MRI) is increasingly used prior to biopsy in response to the overdiagnosis and overtreatment of prostate cancer (CaP) associated with prostate-specific antigen (PSA) based screening. However, technical limitations in the conventional diffusion-weighted imaging (DWI) sequences as well as the high degree of radiologist-to-radiologist variability in interpreting prostate MRI result in inadequate accuracy. Specifically, the insufficient negative predictive value (NPV) of prostate...

Arch Esp Urol. 2021 Oct;74(8):790-795.ABSTRACTOBJECTIVE: To compare systematic biopsy with MRI-TRUS fusion prostate biopsy in terms of cancer detection rates.PATIENTS AND METHODS: The data of the patients who had a Prostate Imaging Reporting and Data System (PI-RADS) score of 3 or more lesions on mpMRI and underwent MRI-TRUS fusion biopsy with simultaneous 12-core standard systematic biopsy from June 2016 to June 2019 in our tertiary center were retrospectively reviewed. Clinical, radiological and pathological data were recorded. Statistical difference among the groups was determined by using McNemar tests.RESULTS: A total...
