A new PI-RADS version improves earlier guidelines for more consistent image acquisition, interpretation, scoring and reporting... keep reading
The renowned British poet Elizabeth Barrett Browning composed one of the most famous love sonnets of all times: How do I love thee? Let me count the ways. It is a declaration of the love she had for her husband, Robert Barrett. Had she been a 21st century radiologist with an equal gift for words, keep reading
The late physicist Stephen Hawking was one of the most brilliant minds of his time. He believed that Artificial Intelligence (AI) could serve the good of the world. He also got the world’s attention when he warned about the danger that AI could eventually outsmart humanity. He urged that its creators exercise responsibility with best keep reading
The tremendous international interest in 3T multiparametric MRI (mpMRI) brought with it the challenge of how to standardize the reporting of prostate image analysis among radiologists around the globe. The European Society of Urogenital Radiology (ESUR) proposed a numeric system called the Prostate Imaging Reporting and Data System, or PI-RADS, for prostate cancer detection. It keep reading
Let’s pretend that you are a prostate cancer patient whose doctor, a well-known robotic surgeon, recommends robotic-assisted radical prostatectomy (RRP). He makes some very persuasive points: Based on the Partin tables you have less than a 12% chance of biochemical recurrence (rising PSA) in three years after treatment. He’ll “get it all out” and you keep reading
“Change is inevitable. Progress is optional.” Tony Robbins In medicine, change sometimes happens with two steps forward but one step back. For example, in the early 20th century, delivering babies in hospitals became more popular than home births in order to have “painless” births with anesthesia. However, for many women the higher complication and infection keep reading
Two problems face men who have a high PSA or abnormal digital rectal exam (DRE). First, they are often referred for a conventional TRUS needle biopsy of the prostate because there is suspicion of prostate cancer (PCa). Second, multiparametric MRI is considered too time-consuming and expensive for routine determination of the need for a biopsy. keep reading
There are so many benefits to detecting prostate cancer (PCa) using multiparametric MRI that it’s hard to single out just one. However, the merits of mpMRI to find PCa in large glands deserve a spotlight. First, a word about prostate size. An average adult gland in younger men is about 30 – 40cc, roughly the keep reading
Terrific news and a great way to start off 2017! On January 17, the prestigious medical journal The Lancet issued online publication of a British study, “Diagnostic accuracy of multi-parametric MRI and TRUS biopsy in prostate cancer (PROMIS): a paired validating confirmatory study” (Ahmed et al., 2017[i]). This large trial validated the importance of multiparametric keep reading
Men suspected of having prostate cancer based on rising PSA or abnormal DRE are typically sent for a transrectal ultrasound (TRUS) guided biopsy using 12 or more needles. At least 30% of TRUS biopsies miss the disease that is present, not to mention the possible side effects of the biopsy itself. What happens next? The keep reading
