Chest CT is emerging as a valuable diagnostic tool for clinical management of COVID-19 associated lung disease. Artificial intelligence (AI) has the potential to aid in rapid evaluation scans differentiation findings from other entities. Here we show that series deep learning algorithms, trained diverse multinational cohort 1280 patients localize parietal pleura/lung parenchyma followed by classification pneumonia, can achieve up 90.8% accuracy, with 84% sensitivity and 93% specificity,...

The purpose of this study was to understand the extent, nature and variability current economic burden prostate cancer among Australian men. An online cross-sectional survey developed that combined pre-existing measures new questions. With few exceptions, viable acceptable participants. main outcomes were self-reported out-of-pocket costs diagnosis treatment, changes in employment status household finances. Men recruited from support groups throughout Australia. Descriptive statistical...

The purpose of this study was to prospectively evaluate Prostate Imaging Reporting and Data System version 2.1 (PI-RADSv2.1), which released in March 2019 update 2.0, for prostate cancer detection with transrectal ultrasound-MRI fusion biopsy 12-core systematic biopsy.

Patients diagnosed with high risk localized prostate cancer have variable outcomes following surgery. Trials of intense neoadjuvant androgen deprivation therapy (NADT) shown lower rates recurrence among patients minimal residual disease after treatment. The molecular features that distinguish exceptional responders from poor are not known. To identify genomic and histologic associated treatment resistance at baseline. Targeted biopsies were obtained 37 men intermediate- to high-risk before...

Abstract Purpose: For high-risk prostate cancer, standard treatment options include radical prostatectomy (RP) or radiotherapy plus androgen deprivation therapy (ADT). Despite definitive therapy, many patients will have disease recurrence. Imaging has the potential to better define characteristics of response and resistance. In this study, we evaluated multiparametric MRI (mpMRI) before after neoadjuvant enzalutamide ADT. Patients Methods: Men with localized intermediate- cancer underwent a...

ABSTRACT Localized prostate cancer is distinctively characterized by intratumoral heterogeneity, and tumors with more complex evolutionary paths display aggressive characteristics. In clinical trials of intense neoadjuvant androgen deprivation therapy (inADT), patients complete or near-complete responses experience durable remissions. However, the molecular characteristics distinguishing exceptional responders nonresponders at baseline have not been established. Here, we present integrated...

e17567 Background: Patients diagnosed with prostate cancer undergo computed tomography (CT) for pretreatment staging to rule out bone metastases. However, detection and classification of lesions on CT is challenging subject inter-reader variability. We present a cascaded deep learning algorithm automatic in patients cancer. Methods: scans from 56 histopathologically proven were included. An expert radiologist annotated the extent individual (N = 4217) labelled all regions as either benign or...

Abstract Background and purpose: Both multiparametric magnetic resonance imaging (mpMRI) prostate specific membrane antigen (PSMA)-targeting positron emission tomography (PET) have shown promise in early localization of cancer (PCa) recurrence after primary external beam radiotherapy. Detecting brachytherapy for PCa using MRI is significantly hampered by susceptibility artifacts secondary to brachy seeds. Here, we compare the efficacy 18 F-DCFPyL (2-(3-{1-carboxy-5-[(6-...
