Abstract Background A retrospective study was conducted on 71 consecutive patients with suspected prostate cancer (PCa) a mean age of 56 years and underwent mp-MRI the at 3 Tesla MRI. Two readers recognized all prostatic lesions, each lesion had score according to Prostate Imaging–Reporting Data System version 2 (PI-RADS-v2). Purpose To evaluate interobserver agreement PI-RADS-v2 in characteriz...

The usefulness of simulation and enactment in business process modelling is explored by means of studying a simple process. Two roles with interactions (contacts), rework and choices collaborate in the production of a document (loan, policies, etc.) From its Role Activity Diagram (RADs), we construct models for Discrete Event (DE) and System Dynamics (SD) simulation and Process Enactment (PE) i...

Vascular changes in a transplantable neuroblastoma of A/J mice following X-irradiation were studied. X-irradiation with doses lower than 500 rads in a single exposure caused a slight increase in the functional intravascular volume, as measured with s ' Cr-labeled red cells 1 day after the irradiation, and a gradual decrease thereafter. X-irradiation with 1000 and 2000 rads, in contrast, induced...

disease tends to recur in a treated field with a frequency which is inversely related to dose and approaches zero at a dose of approximately 4000 rads, delivered at the rate of about 1000 rads/week. Such doses make the use of megavoltage X-ray beams mandatory to avoid severe skin reactions, but are other wise well tolerated by the normal tissues. The inverse relation ship of recurrence rate to ...

Mice were unilaterally irradiated in either a fission neutron or gamma ray field at various dose rates. Jejunal crypt stem cell survival was analyzed by the multitarget single-hit survival model, which yielded excellent fitting survival curves. At the 1 percent survival level, gamma rays were found to be 20 percent more effective in destroying cells when delivered in a brief pulse of radiation ...

Bladder cancer (BC) is common worldwide, and has aggressive features high rates of relapse despite treatments. Approximately 30% patients present with muscle invasive disease, therefore, risk metastasis. This review provides an overview the state art for ‘Vesical Imaging Reporting Data System’ (VI-RADS). scoring system presents a tool local staging BC been validated across several institutions....

We investigated whether the application of the downgrade criteria to supplemental screening ultrasound (US) for women with negative mammography but dense breasts can reduce the rate of Breast Imaging Reporting and Data System (BI-RADS) categories 3 to 4a without a loss of cancer detection.This retrospective study was approved by the Institutional Review Board, and the need to obtain informed co...

PURPOSE To retrospectively evaluate interobserver variability between breast radiologists by using terminology of the fourth edition of the Breast Imaging Reporting and Data System (BI-RADS) to categorize lesions on mammograms and sonograms and to retrospectively determine the positive predictive value (PPV) of BI-RADS categories 4a, 4b, and 4c. MATERIALS AND METHODS Institutional review boar...
