New Ultrasound Imaging Technique Detects Prostate Cancer with More Accuracy, Study Says
A variation of ultrasound imaging, called shear wave elastography (SWE), may help detect signs of prostate cancer with higher accuracy and reliability than current methods, according to new research. The study, “Performance characteristics of transrectal shear wave elastography (SWE) imaging in the evaluation of clinically localised prostate cancer: a prospective study,” was published in the Journal of Urology. Prostate cancer diagnosis now relies on a blood test that measures the amount of a marker, called prostate specific antigen (PSA), along with physical examination of the prostate, known as a digital rectal examination. These methods, however, are far from perfect: PSA test results may be unreliable, and the physical examination is unable to distinguish a benign from a malignant tumor. As a result, patients often undergo magnetic resonance imaging (MRI) scans — which is expensive and not always readily available — and ultimately a biopsy of the prostate tissue — an invasive and expensive surgical procedure. "Prostate cancer is one of the most difficult to pinpoint. We are still in a position where our diagnosis of prostate cancer is extremely inefficient, leading to unnecessary treatments for many patients,” Ghulam Nabi, professor of Surgical Uro-oncology at the University of Dundee in Scotland and the study's lead author, said in a press rele
