Ultrasound guided biopsy of the prostate is the basis of prostate cancer diagnosis, but 60% of the time no cancer is detected. There are numerous investigations aimed at better selecting the patients who ought to undergo prostate biopsy, therefore avoiding unnecessary biopsies.

Currently, early diagnosis of prostate cancer (PCa) depends largely on the result of the prostate specific antigen (PSA) blood test along with a digital rectal examination. Both tests are non-specific, so a positive result can trigger performance of a prostate biopsy to confirm diagnosis.
For example, PSA can be elevated in patients without prostate cancer, including in those who have a large prostate due to benign prostatic hyperplasia, older men with BPH, and those who have prostatitis or a urine infection.
Ultrasound guided prostate biopsy is the basis for diagnosis of PCa. But, of those patients who undergo biopsy due to digital rectal examination and/or a PSA suggestive of prostate cancer, 60% have no malignancy detected on histology. In other words, of every 100 patients who undergo prostate biopsy due to suspected PCa (suspicious digital rectal examination and/or raised PSA), only 40 have prostate cancer. The remaining 60 have undergone an invasive procedure, with possible adverse effects, but have a benign result.
The high percentage of initially negative biopsies, which are then repeated afterwards, involve considerable healthcare costs and impact negatively on patients’ quality of life due to the complications which can occur.
3 TESLA MRI OFFERS HIGHER PRECISION IN A SHORTER TIME.
The 3 Tesla MRI machine has a more powerful magnet, producing better images of the organs and soft tissue than other types of MRI. The high-quality images obtained allow radiologists to precisely differentiate between benign and malignant lesions, with more certainty, leading to an earlier and more accurate diagnosis. The equipment improves the capacity to see smaller prostate tumours.
From the healthcare point of view, patient comfort is improved, as higher quality images are obtained in a shorter time, reducing patient waiting times. Within the area of molecular imaging, it provides new possibilities for early cancer diagnosis.
Whilst innovative diagnostic imaging is being implemented widely due to scientific endorsement, it is certainly still not available in all centres. At HC Marbella we already provide 3T MRI, ensuring an improved and faster diagnosis whilst improving patient experience.
