Artemis Fusion Guided Biopsy: Targeted Painless Accurate

MRI Guided Prostate Biopsy – Dr Peter Swindle QProstate

Prostate cancer can only be definitively diagnosed by means of a needle biopsy for laboratory analysis. Imaging alone cannot provide the cellular and genetic information we need to formulate a treatment plan. In fact, The Scionti Prostate Centers position is that it is unethical to put a man through treatment for prostate cancer without a needle biopsy to confirm and characterize the prostate cancer.

Many men fear the traditional TRUS guided biopsy that takes 12-14 needles. It is inaccurate up to 51% of the time and cannot accurately identify all the cancerous regions of the prostate gland. Our Center offers a painless targeted biopsy using advanced MRI fusion imaging. This has been referred to as a Smart Biopsy. Confirming the true nature of your cancer can be accomplished by selectively sampling the areas revealed by 3D MRI prostate mapping. Artemis® technology makes this possible.

The Scionti Prostate Center utilizes ARTEMIS technology to perform MRI-to-ultrasound precision fusion guided biopsy.We believe that a Smart targeted biopsy more precisely identifies the size, location and stage of a prostate cancer.

This figure illustrates the MRI-to-ultrasound fusion process.Ultrasound images on the left of the diagram are fused or superimposed on a model of the prostate made from MRI images.Biopsies can be directed to the MRI abnormalities.

What Is A Biopsy

A biopsy is a procedure that removes a sample of tissue or cells for study and are most commonly used to look for cancer.

Prostate biopsies are done with a biopsy needle that can be positioned with the assistance of ultrasound images to get samples for testing.

Your doctor might decide you need a prostate biopsy based on the results of a blood test that measures your level of PSA . A high PSA result might point to cancer, but there are other things such as non-cancerous enlargement or infection that cause PSA to rise. Tests that measure derivatives of PSA such as OPKO 4k and Prostate Health Index may be more accurate than PSA in assessing your risk for having a cancer that needs treatment.

Advanced Magnetic Resonance Mapping Targets Cancer

Using a cutting-edge technique for prostate cancer diagnosis and management, our team at University Hospitals uses MRI mapping to identify the exact location of suspicious tissue. We use images from the MRI to distinguish abnormal tissue from normal tissue. This allows our physicians to more accurately identify prostate cancer tumors and lesions, while also tracking their growth.

Although historically believed that MRI machines couldnt detect cancerous tissue, we now know that MRI images accurately identify aggressive cancers. So, with this knowledge, UH physicians developed the non-invasive fingerprinting technique to map the prostate and help distinguish normal from abnormal prostate tissue.

This breakthrough procedure lets UH physicians also monitor the prostate without making men go through unnecessary biopsies or other invasive examinations. As part of our active surveillance treatment, our team is able to monitor the growth of the tumor and determine if more interventional prostate cancer treatment is needed.

Future benefits may be even brighter: University Hospitals has been awarded a $5 million grant from the National Institutes of Health to further develop MRI mapping and the use of artificial intelligence to predict the likelihood of a cancer diagnosis.

How Does It Work

An MRI-guided prostate biopsy occurs in an MRI-positive prostate lesion.

In other words, if there is no highly suspicious lesion in an MRI, theres no reason to spend extra money on a fusion biopsy.

With that in mind, the indications of this type of biopsy include :

  • Patients who had previous transrectal ultrasound biopsies with a negative result but the suspicion is still very high.
  • Patients with a diagnosis of prostate cancer under active surveillance.

After receiving the MRI image, doctors create a prebiopsy MRI map. They use a navigation feature that provides real-time feedback to guide needle location, the optimal patient position, and more.

The doctor may choose between a transperineal or transrectal approach depending on the prostate lesion.

The doctor will usually recommend the former if the patient is susceptible to infections or had a history of .

Fusion-guided biopsy uses a medical imaging software that works by:

  • First, detecting and creating segmentation of the MRI image. In this step, the doctor outlines the prostate and the target lesions. The data is then transferred to a procedure workstation.
  • Registering the image by sweeping the transurethral ultrasound probe until it automatically records the prostate gland.
  • Rigid registration is activated, aligning both images when the patient or the probe moves. The doctor may also choose a manual alignment when necessary.
  • Robotically Assisted Mr Imagingguided Biopsy

    Mri guided prostate biopsy locations

    Robotic technology is currently undergoing evaluation for use in guiding prostate interventions and may increase the accuracy of needle placement in the prostate gland. All robotic components are constructed of nonmagnetic and dielectric materials for MR compatibility. These components are designed to accept as input the high-resolution anatomic and functional information provided by the MR imaging system and to be fully operational in the MR imaging suite.

    Until recently, none of these systems was commercially available. The first commercially available robotically assisted MR imagingguided system was evaluated in a cadaver study , in which it was used to guide prostate interventions performed with a transgluteal approach. Preliminary results show that the use of this type of system has potential for improving prostate interventions .

    The Day Of The Biopsy

    The morning of the exam, give yourself a Fleet enema, which is available over the counter and follow the instructions on the packaging. The enema helps to clean out the rectum and to minimize the risk of infection.

    You may eat a light breakfast and a light lunch before your biopsy, and you should take your usual medications, except for the above-mentioned blood thinners if applicable.

    If you have undergone a recent artificial joint replacement you might need to take additional antibiotics about 1-2 hours prior to the biopsy. Please notify your Urologist if you have a recent history of such procedure, or if you usually take antibiotics before e.g. dental procedures.

    What Happens During An Mri

    These are done in the outpatient procedure area. Antibiotics will be given to reduce the risk of infection from the biopsy. Your doctor will be using the MRI and ultrasound images to watch where the biopsy needles are going. You may feel some discomfort or mild pain when the ultrasound probe is inserted into the rectum. Local anesthesia is used to ease the discomfort.

    What Is A Biopsy And How Effective Is It

    A needle biopsy is the only way to diagnose prostate cancer when it is suspected. But there are problems with the method most commonly used, called transrectal ultrasound guided biopsy. These problems often lead to inaccurate diagnosis.

    For the last two decades, TRUS biopsy has been used to diagnose prostate malignancy. It is actually a blind and random procedure. Specific prostate tumors, especially very small ones, cannot be identified because ultrasound cannot visually detect specific cancer sites. Therefore, it is blind to tumors. In addition, TRUS biopsies tend to target the peripheral aspects of the gland and are likely to miss 30-40% of prostate cancer located in the anterior, midline transition zone, or apex. This is called sampling error. To attempt to overcome it, TRUS biopsies typically average 12-14 needles saturation biopsies use as many as 24 needles. The more needles used, the greater the risk of discomfort, infection, and urinary or sexual side effects while tumors continued to be missed. No other type of tumor cancer is biopsied this way!

    Preparation For The Biopsy

    An Overview of MRI Guided Biopsies for Prostate Cancer

    You cannot take aspirin or other blood thinners, such as Plavix, Eliquis, Brilinta, Pradaxa, Coumadin, Warfarin, Ibuprofen, Naproxen, Aleeve, Advil, Celebrex, Ecotrin, and many others for several days prior to your scheduled biopsy. If you take any of these or other anticoagulants please discuss this with your Urologist beforehand. It might be necessary that you also consult with your Cardiologist prior to stopping.

    Targeted Prostate Biopsy: What You Should Know

    Targeted biopsy is being used at UCLA to diagnose prostate cancer. Targeted biopsy refers to using advanced imaging techniques to identify areas of the prostate suspicious for cancer, and then directly biopsying them. The traditional method of biopsy uses ultrasound imaging, with which tumors are hard to see. With targeted prostate biopsy, systematic sampling of prostate tissue is performed. The new method employs sophisticated MRI technology, developed at UCLA, to visualize prostate cancer, and fusion of the MR images with real-time ultrasound using the specialized biopsy equipment. The result is a 10-20-minute procedure, done in the clinic under local anesthesia, that is much more accurate at finding significant prostate cancer in men.

  • What is MRI with Transrectal Ultrasound Fusion-Guided Prostate Biopsy?
  • Prostate cancer has a new standard of care in MRI-guided fusion biopsy with transrectal ultrasound. While a prostate biopsy has been the only way to get a definitive diagnosis of prostate cancer, it has only been working if cancer cells are identified in the sample tissue. But in some cases, such as when the tumor occurs at the top surface of the prostate or other unusual locations, a biopsy may not give a correct diagnosis. For instance, the standard TRUS guided biopsy in which tissue samples are collected from the prostate in a systematic pattern gives a negative result with tumors located in unusual areas of the prostate. About 15-20 percent of tumor locations can be missed by the biopsy needle.
