Contrast-enhanced ultrasound for prostate cancer imaging
• Need for targeted instead of blind biopsies, in order to reduce false negatives and to improve grading and staging • Need for accurate grading, staging and prognosis, in order to a) reduce side effects by enabling active surveillance and treating only relevant cases and b) avoid recurrence as a result of understaging and inappropriate treatment • Need for targeted therapies (focal local treat...
متن کامل[Transrectal ultrasound in the diagnosis of prostate cancer].
Arguably the most important step in the prognosis of prostate cancer is early diagnosis. More than 1 million transrectal ultrasound (TRUS)-guided prostate needle biopsies are performed annually in the United States, resulting in the detection of 200,000 new cases per year. Unfortunately, the urologist's ability to diagnose prostate cancer has not kept pace with therapeutic advances; currently, ...
متن کاملContrast - enhanced Ultrasound in Prostate Cancer
Previous reports have demonstrated that contrast-enhanced US (CEUS) investigations of the blood flow of the prostate allow for prostate cancer visualisation and therefore for targeted biopsies. Comparisons between systematic and CEUS-targeted biopsies have shown that the targeted approach detects more cancers with a lower number of biopsy cores. CEUS has also been shown to detect cancers with h...
متن کاملThe Utility and Limitations of Contrast-Enhanced Ultrasound for the Diagnosis and Treatment of Prostate Cancer
In association with the widespread use of prostate specific antigen (PSA) screening, the numbers of men identified with early-stage prostate cancer (PCa) are increasing in the developed countries, including Japan. However, the accurate localization of PCa lesions in diagnostic imaging is still difficult because PCa has a tendency to be multifocal in the prostate gland. Contrast-enhanced ultraso...
متن کاملContrast-enhanced transrectal ultrasound for prediction of prostate cancer aggressiveness: The role of normal peripheral zone time-intensity curves
To assess the role of time-intensity curves (TICs) of the normal peripheral zone (PZ) in the identification of biopsy-proven prostate nodules using contrast-enhanced transrectal ultrasound (CETRUS). This study included 132 patients with 134 prostate PZ nodules. Arrival time (AT), peak intensity (PI), mean transit time (MTT), area under the curve (AUC), time from peak to one half (TPH), wash in ...
