Prostate Cancer Detection: What Should I know?

It is commonly thought that the PSA blood test detects prostate cancer. This is not the case. The PSA test is not specific for cancer. A higher result than normal can indicate many noncancerous prostate conditions besides cancer. Therefore, more information is needed. Commonly, urologists recommend an immediate ultrasound-guided needle biopsy (TRUS biopsy), an invasive procedure with risks of pain and infection. Why go through that before knowing if cancer is actually present or having the benefit of identifying a target in the prostate of where it might be?

The Sperling Solution

The Sperling Prostate Center provides a better way to detect prostate cancer before rushing to biopsy.

BlueLaser™ 3T mpMRI: Better Early Detection

If a high PSA raises suspicion of cancer, the next step before biopsy is to obtain an accurate 3D image of the gland that defines both normal and cancerous tissue. It is just as important to see what is healthy as what is unhealthy! Ultrasound doesn’t do this because it can’t reveal specific differences needed to detect what is and isn’t cancer.

Our BlueLaser™ 3T mpMRI Plus features the latest advance in multiparametric imaging sequences. It is called Restricted Spectrum Imaging (RSI) powered by AI, and it takes cancer detection to a whole new level. RSI was originally developed for brain imaging where it accurately picks up previously undetectable but telltale differences in neurological diseases. When applied to prostate imaging, potentially cancerous lesions literally stand out.

Studies now show that combining technological breakthroughs and expertise¹ makes an essential difference. By offering the increased accuracy of both RSI² powered by AI³ together with the pioneering experience of Dr. Sperling and his team, the Sperling Prostate Center remains at the forefront of prostate cancer imaging.
 

RSI-MRI+ leverages an advanced diffusion MRI technique called Restriction Spectrum Imaging, powered by AI, to enable faster, more accurate prostate cancer detection.

If BlueLaser™ 3T mpMRI rules out cancer, it gives peace of mind and avoids a biopsy or other additional testing. If, however, a suspicious area is detected and a biopsy is necessary, we offer the superiority of in-bore MRI-guided targeted biopsy.

Remember: Early prostate cancer has NO SYMPTOMS. Early detection results in better diagnosis, better treatment decisions and better outcomes.

MRI-Guided Targeted Biopsy: Better Diagnosis

Watch Carrol’s video testimonial

A real-time prostate biopsy done in the bore (tunnel) of our powerful 3T magnet excels over all other biopsy methods.⁴ Standard 12-14 needle TRUS biopsies miss 30-40% of tumors. They over-detect insignificant prostate cancer (may not require immediate treatment) and under-detect significant prostate cancer (requires immediate treatment).

In-bore biopsy with fewer needles is twice as accurate as TRUS biopsy.^{5, 6} Patients are often told that a fusion biopsy is an “MRI-guided biopsy” but this is misleading. In fact, fusion is software that relies on previous MRI images overlaid on real-time ultrasound—an image manipulation process with technical pitfalls that can compromise imaging accuracy.⁷ Compare TRUS, fusion, and real-time in-bore MRI biopsies here.

Is BlueLaser™ 3T mpMRI Right for You?

“Knowledge is power only if man knows what facts not to bother with.” -R.S. Lynd

Our BlueLaser™ 3T mpMRI empowers our patients by providing accurate knowledge about what’s going on in their bodies, both normal and disease. You should consider BlueLaser™ 3T mpMRI for the earliest possible detection if:

• You have an elevated or rising PSA
• You have an abnormal DRE
• You were treated for a prostate infection or inflammation but your PSA is still high
• You are on Active Surveillance
• You are in a high-risk category to develop prostate cancer (genetic or environmental factors)
• You have not had a PSA test but you have unusual urinary symptoms

PSA: What’s Normal, and What Does it Mean?

A higher-than-normal PSA can indicate noncancerous conditions such as aging-related enlargement, inflammation, or infection. Certain activities, such as riding a bike or having sex can trigger a temporary increase in PSA that has nothing to do with disease.

On the other hand, up to 15% of men with normal PSA levels can still have prostate cancer.⁸ Even when PSA levels are abnormal, as many as 75% of men end up not having prostate cancer yet have had unnecessary biopsies and worried for nothing.⁹

Also, the Digital Rectal Exam (DRE) is not reliable for detecting prostate cancer. The doctor can only feel the surface of the gland closest to the rectal wall, completely missing small tumors located more deeply where most prostate cancer begins. It is neither thorough nor accurate.¹⁰

Since the likelihood of having prostate cancer increases proportionately with PSA level, there is no threshold below which a man can be reassured that prostate cancer does not exist. PSA levels greater than 4 ng/mL are generally considered suspicious. As levels increase above 10.0 ng/mL, the probability of cancer increases dramatically. However, not all men with prostate cancer have elevated PSA levels, and not all normal PSA levels guarantee that no cancer is present. A small percentage (thought to be less than 15%) of prostate cancers can present with a PSA level of less than 4.0 ng/mL. This is why doctors may use lower thresholds to decide when to do a biopsy.

Excellence in Prostate Cancer Detection

The Sperling Prostate Center is a technologically-advanced, patient-oriented practice dedicated to providing the most effective techniques in prostate cancer detection and diagnosis. Unlike the PSA blood test or DRE, our approach—utilizing BlueLaser™ 3T mpMRI imaging with the newest advances in Restricted Spectrum Imaging, powered Artificial Intelligence—offers the best pathway to diagnostic superiority.
