MR Imaging–Guided Prostate Biopsy Techniques

Magnetic Resonance-Guided Prostate Biopsy

“…Both transrectal and transperineal approaches have been reported using this technique. [12][13][14][15] Prebiopsy MP-MR imaging is performed to identify target lesions. Patients are placed in the prone, supine, or decubitus position.…”

“…Needle localization may be reconfirmed and tracked by further scanning after tissue sampling. 12 When the robotic device is used for MR-GB, it is fixed typically to the scanner table and the needle guide is inserted into the rectum or perineum. After registration of the robot and the needle guide with localization sequences, the robot is controlled remotely to achieve the MR-Guided Prostate Biopsy desired angulation for inserting the needle to target the suspicious lesion.…”

Current prostate biopsy procedures for in the detection of cancer

“…Кроме того, одним из недостатков является то, что пациент во время процедуры не должен двигаться, даже дыхательные движения могут исказить данные [27].…”

The emerging role of extracellular vesicles as biomarkers for urogenital cancers

“…Although surgical treatment and chemotherapy for urogenital cancers have improved in the last decade, the prognoses for these diseases remain poor, as existing tests are not sufficiently sensitive or specific to diagnose uro genital cancers at early stages, and none has been shown to signifi cantly decrease overall mortality. Current diagnostic procedures include general examinations and biopsies, such as image-guided prostate biopsy, 3 cystoscopy and transurethral resection of the bladder, 4 nephrectomy and percutaneous renal tumour biopsies, 5 all of which lack sensitivity and can be associated with significant health complications (for example, biopsies are invasive procedures associated with bleeding and risk of infections). Moreover, the location of uro genital cancers deep within the pelvic region makes them hard to access.…”
