Dynamic Contrast Enhanced, Pelvic Phased Array Magnetic Resonance Imaging of Localized Prostate Cancer for Predicting Tumor Volume: Correlation with Radical Prostatectomy Findings. - UroToday

-

PURPOSE: We assessed the value of pelvic phased array dynamic contrast-enhanced magnetic resonance imaging for predicting the intraprostatic location and volume of clinically localized prostate cancers. 

MATERIALS AND METHODS: Suspicious areas on prospective pre-biopsy magnetic resonance imaging in 24 patients were assigned a magnetic resonance imaging malignancy score and located with respect to anatomical features, gland side, and transition and peripheral zone boundaries. The largest surface area and volume were measured. These magnetic resonance imaging findings were compared with radical prostatectomy specimen histopathology findings.

RESULTS: Histopathology maps detected 56 separate cancer foci. The largest tumor focus was located in the peripheral zone in 14 patients and in the transition zone in 10. T1-weighted dynamic contrast-enhanced magnetic resonance imaging identified 30 of the 39 tumor foci greater than 0.2 cc and 27 of the 30 greater than 0.5 cc. T2-weighted sequences were suspicious in 22 of 30 foci greater than 0.2 cc that was identified by T1-weighted dynamic contrast-enhanced magnetic resonance imaging sequences. Sensitivity, specificity, and positive and negative predictive values for cancer detection by magnetic resonance imaging were 77%, 91%, 86% and 85% for foci greater than 0.2 cc, and 90%, 88%, 77% and 95% for foci greater than 0.5 cc, respectively. Median focus volume was 1.37 cc (range 0.338 to 6.32) for foci greater than 0.2 cc detected by magnetic resonance imaging in the peripheral zone and 0.503 cc (range 0.337 to 1.345) for those not detected by magnetic resonance imaging (p <0.05). Corresponding median values for transition zone foci were 2.54 (range 0.75 to 16.87) and 0.435 (range 0.26 to 0.58).

CONCLUSIONS: Pre-biopsy pelvic phased array dynamic contrast-enhanced magnetic resonance imaging is an accurate technique for detecting and quantifying intracapsular transition or peripheral zone tumor foci greater than 0.2 cc. It has promising implications for cancer detection, prognosis, and treatment.

fluciclovine f 18 :: Article Creator The U.S. Navy Might Be Done With The F/A-18 Super Hornet Fighter Will The U.S. Navy Receive Its Final F/A-18 Super Hornets? - Around the holidays, money can be tight, a fact that the United States Navy has also learned as its negotiations to buy the last batch of Super Hornets are reportedly stalled over the growing price tag. USNI News reported on Tuesday that the contract for the U.S. Navy to purchase the final twenty F/A-18 E/F Super Hornets from aerospace giant Boeing appears to be at a standstill. The Navy continues to work with Boeing on the contract for the 20 congressionally added Super Hornet aircraft. Ongoing contract negotiations cannot be discussed at this time," Capt. Michael Burks, the program manager for the F/A-18 and EA-18G office at Naval Air Systems Command, told USNI News in a statement. Previous estimates put the unit cost of the final batch of aircraft at $55.7 million, and la

leukemia treatment options :: Article Creator Current And Breakthrough Treatments For Chronic Lymphocytic Leukemia (CLL) Chronic lymphocytic leukemia (CLL) is a slow-growing cancer of the immune system. Because it's slow-growing, many people with CLL won't need to start treatment for many years after their diagnosis. Once the cancer begins to grow, there are many available treatment options that can help people achieve remission. This means people can experience long periods of time when there's no sign of cancer in their bodies. The exact treatment option that you'll receive depends on a variety of factors. This includes: whether your CLL is symptomatic the stage of the CLL, based on results of blood tests and a physical exam your age your overall health While there's no cure for CLL yet, breakthroughs in the field are on the horizon. Doctors typically stage CLL using a system called the Rai system. Low
