“…The detection of cancers having extracapsular extension (ECE) might be improved by using high power field MRI. Three tesla MRI (3T-MRI) is reported to have higher sensitivity and specificity (66.7% and 100%) for detection of ECE in PCa than 1.5T-MRI [10].…”

“…As with 1.5T MRIs, ERCs cause significant changes in the prostate dimensions and a significant volume decrease, making image registration with the radiation treatment planning CT challenging [4]. Some investigators have suggested the resolution provided by 3T MRI without an ERC is as good as the 1.5T MRIs with an ERC [5][6][7][8]. Although performing 3T MRI without an ERC would have a number of advantages, including less patient discomfort, lower costs, and better correlation with RT planning, it is not widely available.…”

Radiation therapy (RT) for prostate cancer has made huge strides over the past two decades. The addition of image guidance has allowed radiation oncologists to ensure accurate delivery of increasingly precise radiation treatment plans using newer conformal therapy methods such as three-dimensional conformal RT, intensitymodulated RT, and proton beam RT. Regardless of the specific treatment technique, patients can depend on the treatment to target the moving prostate effectively while significantly sparing adjacent tissues, thereby reducing the morbidity of having to undergo prostate cancer therapy. This review summarizes the recent technical advances made in radiation dose delivery, including target volume definition, treatment planning, treatment delivery methods, and positional verification methods during RT.

“…Owing to the large variety of study conditions, in particular with respect to patient groups, readers and methodology, it is generally difficult to evaluate the results independently. For 3 T studies without an endorectal coil, however, it can be observed that either the sensitivity [8, 20,23] or specificity was found to be below 80 % [6] while both values were higher than 80 % [8,18] in two studies with an endorectal coil, at least for experienced prostate MRI readers (3 years, 250 cases). The good local staging accuracy of 3 T MRI with an endorectal coil, with sensitivities and specificities for ECE and SVI detection largely above 80 %, is confirmed in this study.…”

Purpose: To assess the accuracy of endorectal 3?T magnetic resonance imaging (MRI) in detecting extracapsular extension (ECE) and seminal vesicle invasion (SVI) of prostate cancer (PCa). Materials and Methods: 38 consecutive patients with biopsy-proven PCa underwent multiparametric endorectal MRI at 3?T prior to prostatectomy. Two readers (A with nine years of experience and B with four) used established criteria for ECE and SVI to diagnose the extent of local disease in six regions (apical, dorsolateral, basal; left and right each) with the highest chance of ECE. The standard of reference was provided by intraoperative frozen section analysis and prostatectomy specimens. Results: Histopathology revealed ECE in 15 of the 222 regions (10 of 37 patients) and SVI in 8 of 74?potential regions (5 of 37 patients). The sensitivity, specificity, and accuracy in detecting ECE for reader A/B were 93?%/67?%, 92?%/95?% and 92?%/93?% per region and 90?%/80?%, 74?%/82?% and?78?%/81?% per patient, respectively. The corresponding values for the detection of SVI were 80?%/100?%, 96?%/99?% and 95?%/97?%, respectively. Conclusion: Endorectal 3?T MRI is a highly reliable noninvasive technique for the local staging of PCa. Key points: ??Endorectal 3?T MRI provided high accuracy for the local staging of prostate cancer. ??The sensitivity in detecting extracapsular tumor growth per patient was 80?% or higher. ??The specificity in detecting extracapsular extension (pT3 stage) was good.

Accuracy of 3-Tesla magnetic resonance imaging for the staging of prostate cancer in comparison to the partin tables

Abstract: 3T MRI showed a high accuracy for the staging of clinically localized prostate cancer, and it was significantly more accurate in predicting the final pathological stage than the Partin tables.
