چکیده

Ultrasonografia będzie nadal wiodącą metodą w biopsji transrektalnej gruczołu krokowego pod kontrolą ultrasonografii (transrectal ultrasound, TRUS). Niemniej jednak obrazy ultrasonograficzne są gorszej jakości i mniej dokładne niż obrazy MR. Poza większym kontrastem tkanek miękkich i uzyskiwaniem obrazów o dużej rozdzielczości, rezonans magnetyczny umożliwia kompleksową ocenę tkanek: na przykład na obrazach T2-zależnych – anatomii/ topografii, w badaniu po dożylnym podaniu kontrastu oraz obrazowaniu zależnym od dyfuzji (diffusion-weighted imaging, DWI) – patofizjologii (tkanka/guz, perfuzja/dyfuzja), a w spektroskopii – metabolizmu/cząsteczek. Badanie MR jest względnie zależne od operatora, a wyniki są powtarzalne. Udowodniono wyższą czułość, swoistość i dokładność tej metody w wykrywaniu oraz ocenie zaawansowania raka stercza(3,4). In response to the article of Szopiński et al.(1) we want to compliment the authors for a very thorough and sound review article. The authors listed the most signifi cant developments and trends in prostate ultrasound, and mentioned the increasing role of MRI in prostate cancer diagnosis and staging.

The future perspectives in transrectal prostate ultrasound guided biopsy

Prostate cancer is one of the most common neoplasms in men. Transrectal ultrasound (TRUS)-guided systematic biopsy has a crucial role in the diagnosis of prostate cancer. However, it shows limited value with gray-scale ultrasound alone because only a small number of malignancies are visible on TRUS. Recently, new emerging technologies in TRUS-guided prostate biopsy were introduced and showed hi...

بررسی ارزش Diffusion Weighted Imaging در تصاویر MRI برای تشخیص سرطان پروستات

Background: Prostate cancer is the third leading cause of death and is the most common cause of cancer in elderly men. Regarding to the low accuracy of screening methods such as prostate-specific antigen (PSA), Digital Rectal Examination (DRE) and trans rectal ultrasound (TRUS) in detection and localization of tumor, Magnetic Resonance Imaging (MRI) and Diffusion Weighted Imaging (DWI) attracte...

The role of imaging in the diagnosis of primary prostate cancer

Ultrasound and magnetic resonance imaging (MRI) are key imaging modalities in prostate cancer diagnosis. MRI offers a range of intrinsic contrast mechanisms (T2, diffusion-weighted imaging (DWI), MR spectroscopy (MRS)) and extrinsic contrast-generating options based on tumour vascular state following injection of weakly paramagnetic agents such as gadolinium. Together these parameters are refer...

MR-guided interventions for prostate cancer.

MR imaging is currently the most effective diagnostic imaging tool for visualizing the anatomy and pathology of the prostate gland. Currently, the practicality and cost effectiveness of transrectal ultrasound dominates image guidance for needle-based prostate interventions. Challenges to the integration of diagnostic and interventional MR imaging have included the lack of real-time feed-back, t...

Optimization of clinical target volume delineation using magnetic resonance spectroscopic imaging (MRSI) in 3D conformal radiotherapy of prostate cancer

Background: For the purpose of individual clinical target volume assessment in radiotherapy of prostate cancer, MRSI was used as a molecular imaging modality with MRI and CT images. Materials and Methods: The images of 20 prostate cancer patients were used in this study. The MR and MRSI images were registered with CT ones using non-rigid registration technique. The CT based planning (BP), CT/MR...
