PSA (prostate specific antigen) is an enzyme that allows liquefaction of semen, which is secreted by the prostate cells. It requires a blood sample. The level of PSA is increased due to prostate cancer. Urinary catheterization, cystoscopy (viewing of the bladder with a camera system), ejaculation shortly before the test, prostatitis, prostate biopsy, prostate surgery and prostate massage may cause temporary elevation of PSA levels.
If there is an elevation of blood PSA levels, if there are any firmness/irregularities determined during the prostate exam or if there are MRI-detected suspicious areas present, a PROSTATE BIOPSY should be performed for early diagnosis.
Prostate biopsy is performed by taking multiple samples guided by rectal prostate ultrasound as standard. However, especially in case of a need for repetitive biopsy, Fusion Guided Prostate Biopsy method,which is superior in tumor detection, is recommended instead of standard ultrasound-guided prostate biopsy. Fusion Guided Prostate Biopsy combines the suspicious areas in advanced multiparametric MRI images with the live ultrasound images to take spot-on biopsy samples from the suspicious areas with minimal deviation. First, MRI images are converted to 3D images and suspicious areas are marked in these 3D images. 3D MRI images are simultaneously combined with the real-time ultrasound images to visualize the suspicious areas during biopsy and allow spot-on sampling.
With fusion guided prostate biopsy, it is possible to reduce the number of samples, thereby lowering the risk of infection and bleeding. Also, since the biopsy is performed with minimal deviation from the suspicious area, the diagnosis is made more accurately and the need for repetitive biopsies are minimized.
