Extended biopsy schemes take 12 to 14 cores from the prostate gland through a thin needle in a systematic fashion from different regions of the prostate. [5] A biopsy procedure with a higher rate of cancer detection is template prostate mapping (TPM) or transperineal template-guided mapping biopsy (TTMB), whereby typically 50 to 60 samples are ...
Transperineal biopsies, on the other hand, offer several advantages, including greater accuracy, a lower risk of infection, and better visualization of the prostate. The patient may be given a mild sedative and the perineum will be numbed with a local anaesthetic.
a needle biopsy taken via the rectum and, surgical removal of prostate tissue: transurethral resection of the prostate - removal of extra prostate tissue to improve urination (a treatment for benign prostatic hyperplasia), radical prostatectomy - complete removal of prostate and seminal vesicles (a treatment for prostate cancer).
MRI guided techniques have improved the diagnostic accuracy of the procedure. [ 12 ] [ 13 ] Biopsies can be done through the rectum or perineum . [ 29 ] The biopsy technique includes factors such as needle angle and prostate mapping method. [ 30 ]
An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration ...
[5] [citation needed] She has worked on a combination of multi-parametric MRI and cognitive fusion transperineal biopsy, which can reduce the time taken diagnose and treat diseases. [6] [citation needed] She has found that using MRI can reduce the need for biopsies by 28%.
A similar paper in European Radiology found that when correlated with histopathology, PI-RADS v2 correctly identified 94-95% of prostate cancer foci ≥0.5 mL, but was limited for the assessment of GS ≥4+3 (significant) tumors ≤0.5 mL; in their series, DCE-MRI offered limited added value to T2WI+DW-MRI.

Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.
