A thorough understanding of the physics of artifacts is critical to producing good quality images that give a true understanding of the underlying structures of the prostate. Artifacts in ultrasound can be defined as depictions of structures or processes that do not accurately reflect the true ...
(31), the location of tumor nodules can significantly influence whether the dose escalation will, or will not, lead to improved outcomes. When the tumor borders with a critical organ, dose escalation may not be possible. As we continue our ultrasound-guided prostate dose escalation project, we...
Talk to your healthcare provider: Ask the healthcare provider who found or suspects your cancer for recommendations. Ask for two or three names and what their specialties are. Don't be afraid to ask, "If you or someone you loved were in my situation, whom would you go to for treatment?
To describe our experience with transrectal ultrasound (TRUS)-guided needle biopsy of pelvic malignancies. Eleven patients with clinical suspecion of advanced malignant pelvic tumor were referred to our institution with a history of unsuccessful CT-guided biopsy, although a target lesion was demonstrated...
Transrectal ultrasound (TRUS) is used for many prostatic interventions including prostate biopsy, brachytherapy, cryotherapy, to monitor the application of high intensity focused ultrasound (HIFU), and during the investigation of male factor infertility and hemospermia....
For a urological evaluation of such complaints in men, the International Prostate Symptom Score (IPSS) is used worldwide. Previous quantitative studies have revealed serious problems in completing this questionnaire. In order to gain insight into the nature and causes of these problems, we conducted...
For classification tasks, a sigmoid or a softmax activation function is typically used to calculate class probabilities, providing the final output of the CNN [25,26]. A sigmoid function is commonly employed in binary classification, producing a single probability score indicating the likelihood of ...
Simple Summary: Prostate cancer screening has traditionally been accomplished by a blood test for prostate serum antigen (PSA) followed by biopsy. MRI is very accurate at finding cancer, but ultrasound provides real-time guidance for biopsy. Using magnetic resonance imaging (M...
We analyze the main imaging techniques (transrectal ultrasound, Magnetic Resonance Imaging and Position Emission Tomography) that are currently used in the...vekri
Rationale and key points This article aims to help nurses to support patients who require a prostate biopsy to diagnose or exclude prostate cancer. Nurses will also gain an understanding of the procedure for transrectal biopsy.Charles...
