BACKGROUND Elastographpy is a newly developed noninvasive imaging technique that uses ultrasound (US) to evaluate tissue stiffness. The interpretation of the same elastographic images may be variable according to reviewers. Because breast lesions are usually reported according to American College of Radiology Breast Imaging and Data System (ACR BI-RADS) lexicons and final category, we tried to ...

conclusion this study shows no significant improvement in the cancer detection rate by double reading; however, a lower recall rate could be a more helpful consequence. results readers had consensus on bi-rads categories in 459 breasts (71%), but diverse categories were used for 183 breasts (29%), including 132 significant and 51 non-significant discrepancies. according to weighted kappa test, ...

PurposeTo determine the prevalence and determinants of radiologic imaging requests that are inadequate quality according to Reason for exam Imaging Reporting Data System (RI-RADS).MethodsThis study included a random sample 673 examinations performed at tertiary care center. The each request was graded RI-RADS. Ordinal regression analysis association RI-RADS grade with patient age, gender, hospi...

Purpose: The Prostate Imaging Reporting and Data System (PI-RADS) was introduced to standardize prostate cancer diagnosis by MRI. However, the inter-reader agreement PI-RADS scoring is not always high. purpose of this study validate a deep-learning-based diagnostic algorithm PI-RADS. Methods: We applied Siemens Healthineers Artificial Intelligence (AI) prototype (work in progress) for fully aut...

PURPOSE The purpose of this study was to retrospectively investigate the reliability of breast ultrasound (US) Breast Imaging Reporting and Data System (BI-RADS) final assessment in mammographically negative patients with pathologic nipple discharge, and to determine the clinical and ultrasonographic variables associated with malignancy in this group of patients. METHODS A total of 65 patient...

Minimally invasive surgery (MIS) during cardiovascular interventions reduces trauma and enables the treatment of highrisk patients who were initially denied surgery. However, restricted access, reduced visibility and control of the instrument at the treatment locations limits the performance and capabilities of such interventions during MIS. Therefore, the demand for technology such as steerabl...

A study was made on the loss of the reproductive capacity of HeLa S3 cells irradiated in vitro under both oxygenated and anoxic conditions with D-T neutrons (14 Mev) at 1, 20, 30, 150 and 400 rads/minute at 25•Ž and 37•Ž and with 180 kvp X-rays at 100 rads/minute at 37•Ž. 1) RBE of neutrons measured at a range of 2 to 10% survival was 2.67-2.62 under oxygenated conditions and 3.83.4.61 under an...

The researchers reviewed 1,523 consecutive breast MRI exams performed from Jan. 1, 2003, to June 30, 2005, to identify all lesions initially detected on MRI and assessed as BI-RADS 4 or 5 for which the patient underwent subsequent imaging-guided needle or excisional biopsy. They recorded BI-RADS lesion features for each case and the risk of malignancy was assessed using generalized estimating e...

The in vitro response of 53 human diploid fibroblast strains to X-irradiation was studied using a clonogenic survival assay. The strains, derived from patients with a variety of characterized clinical conditions, most with a genetic component, ranged in Do (a measure of the slope of the survival curve) from 43 to 168 rads. The mean Do's of six strains from normal individuals was 140 to 152 rads...

A time-domain multiwavelength (635 to 1060 nm) optical mammography was performed on 147 subjects with recent x-ray mammograms available, and average breast tissue composition (water, lipid, collagen, oxy- and deoxyhemoglobin) and scattering parameters (amplitude a and slope b) were estimated. Correlation was observed between optically derived parameters and mammographic density [Breast Imaging ...
