Zwanger-Pesiri Offer Unique MRI/PET Scanner

On November 11, at its newest facility in Lynbrook, Zwanger-Pesiri Radiology has once again led the way in medical imaging by being the first private radiology facility in the United States to acquire an MRI/PET (Magnetic Resonance Imaging/Positron Emission Tomography) scanner. The Biograph mMR, by Siemens, is the only FDA-approved device that has the ability to acquire both an MRI and a PET scan simultaneously—leading to better detection, characterization, and treatment of oncologic, neurologic, and cardiac diseases.

For many years before the Biograph mMR was available, the modality of choice had been PET/CT, a hybrid modality that performs both a PET (Positron Emission Tomography) and a CT (Computed Tomography) scan. However, because of the dangers of radiation exposure with CT and its low soft-tissue resolution, radiologists have chosen to use software techniques that combine a patient’s MRI scan with the patient’s PET scan—creating fused MRI/PET studies. Due to motion and alignment issues with fusing two exams from two different scanners, diagnosing certain diseases was problematic—but not anymore.

The simultaneous imaging of MRI and PET with the Biograph mMR scanner will:

• Eliminate CT radiation exposure that is received from PET/CT scans—which is equivalent to approximately 100 chest X-rays.

• Provide superior soft tissue information compared to PET/CT, thus increasing the sensitivity and specificity of the exam.

• Increase diagnostic confidence by eliminating motion from two separate scans.

• Reduce the number of office visits and acquisition time by combining two important imaging techniques in one system.

“These points are of the utmost importance to us here at Zwanger-Pesiri,” says CEO Steven L. Mendelsohn, MD. “Not only are we committed to giving our patients access to the most advanced imaging techniques on the market, but we are dedicated to reducing radiation exposure whenever possible. The fact that MRI/PET delivers better diagnostic information than PET/CT and reduces radiation exposure equivalent to 100 chest X-rays, is what makes this modality an integral part of who we are and what we stand for.”

Since 2011, when the Biograph mMR was first available in the United States, there have been approximately nine units installed. However, all are located in hospital environments and mostly used for academic and research purposes.

“We know that by having an MRI/PET unit at Zwanger-Pesiri, patients and physicians around the country, and even the world, will now have access to this valuable imaging modality in a more private, comfortable and family-like environment. And being that Lynbrook is only 15 minutes away from John F. Kennedy International Airport, this office will be accessible to many,” says Robert Day, chief operating officer of Zwanger-Pesiri Radiology.

Zwanger-Pesiri Radiology, one of the largest and most respected practices on Long Island, has been serving the community for over 60 years. To date, there are 18 locations in Nassau and Suffolk counties, each providing a range of radiological procedures such as MRI/PET, breast MRI, cardiac and vascular CTA, digital and 3D mammography, PET/CT, digital X-ray, nuclear medicine, ultrasound, and more.

Zwanger-Pesiri has a team of over 60 certified radiologists who have multiple subspecialties including vascular imaging, interventional radiology, neuroradiology, musculoskeletal imaging, abdominal radiology, cardiovascular radiology, and breast imaging. Zwanger-Pesiri Radiology strives to provide the most advanced technology available with a strong focus on delivering a quality of care unmatched in the industry. For more information, visit
