Nassau Radiologic Group facilities feature the most advanced medical diagnosis and treatment equipment available.   These include the latest 3-dimensional treatment planning computers, computed tomography (CT scanners), magnetic resonance imaging (MRI) units, mammography units, nuclear imaging, ultrasound equipment, and more. 

GE Discovery ST 

The GE DISCOVERY ST Whole body PET/CT System is a state-of-the-art Computed Tomography and Positron Emission Tomography Scanner. The system combines the high performance of an 8 slice CT. The multislice CT scan reduces artifacts associated with respiration motion as well as metal artifact associated with dental implants and orthopedic hardware. The advanced PET scanner is optimized for routine 3D clinical studies as well as 2D for patients with large body habitus.

Discovery ST has capabilities for imaging all available PET tracers, provides superior image quality, and fast imaging times (30 minutes or less).

Discovery ST features a large bore, reducing the feeling of claustrophobia. It is an ideal solution for your radiation therapy planning and treatment needs by targeting areas of disease while sparing normal tissue.

Spiral Computed Tomography   (CT Scanning)

Computed Tomography, or CT Scanning, allows NRAD physicians to view thin cross-sections of the internal anatomy using the latest in spiral scanning techniques.  Spiral, also called Helical CT, combines x-rays and sophisticated computers to produce detailed images of the brain, spine, chest abdomen and pelvis.  The presence and extent of disease and the effects of certain traumatic events can thus be identified.  CT scanning is also helpful in the evaluation of certain musculoskeletal disorders.

Nassau Radiologic Group (NRAD) uses CT systems manufactured by GE Medical Systems and the Siemens Corporation -- both of whom are world leaders in medical imaging technology.

Magnetic Resonance Imaging   (MRI)

Magnetic Resonance Imaging (MRI) is considered one of the greatest medical breakthroughs since the discovery of x-rays in 1895.  In use since the early 1980's MRI systems use a combination of advanced magnets and radio wave technology to produce images of the human body with the clarity of anatomical textbook illustrations.  MRI is extensively used in studying the brain and spine as well as the body and the musculoskeletal system.  MRIs are also used to image blood vessels and provide insight into the chemical components of selected tissue.

Nassau Radiologic Group (NRAD) uses both Open and Closed MRI equipment manufactured by GE Medical Systems, Siemens Corporation and Hitachi -- used in the majority of the world's MRI research facilities.

Nuclear Medicine

Nuclear medicine addresses the body's physiological processes rather than the anatomical structure.  In nuclear imaging, short-lived radioactive drugs that emit gamma rays (radiopharmaceuticals) are injected into a patient's bloodstream and are attracted to the particular organ being analyzed.  A nuclear camera then takes a time-exposure image of the pharmaceutical as it enters the bloodstream and concentrates in the tissues or organs.  A nuclear physician then is able to trace the blood flow activity and analyze information about the biological activity of the organ and its related vascular system.

Nuclear Medicine has a wide variety of uses, including cancer diagnosis, heart disease, circulatory systems, kidney malfunctions, and other abnormalities in veins, tissues and organs.  Nassau Radiologic Group (NRAD) uses nuclear imaging equipment manufactured by GE Medical Systems.

Oncology Treatment Facilities

Long Island Radiation Therapy with offices in Garden City and Manhasset -- provide patients with state-of-the-art cancer treatment.  Both centers offer a bright, airy environment and feature some of the most modern oncology treatment equipment available.

Our Siemens Linear Accelerator unit pictured above is used in Cancer treatment at Long Island Radiation Therapy.

Our 3-D Treatment Planning Computers enable our radiation oncologists to develop a therapeutic regimen for each patient to optimize radiation effectiveness on treatment areas.  Our Siemens MEVASIM S Simulator allows exact localization of the treatment area.

We have four Siemens Digital MEVATRON linear accelerators, each with superior beam quality, integrated safety features and fast set-up to ensure precise treatment.  All are integrated with an IMPAC Record & Verify System capable of inter-office communication providing an additional layer of safety.

Positron Emission Tomography  (PET Imaging)

Long Island PET Imaging, an affiliate of Nassau Radiologic Group, P.C., was established in 2001 for the accurate non-invasive detection and staging of many forms of cancer, the evaluation of many brain disorders, and assessment of cardiac tissue damage.

Based in Lake Success, our state-of-the-art facilities are equipped with the latest Siemens ECAT ART PET system.  Our imaging services are staffed by professionally credentialed technologists and nurses.  All imaging studies are provided by national board-certified radiologists, with subspecialty training.

Positron Emission Tomography, known as PET imaging, enables physicians to analyze chemical or physiological changes related to metabolism.  Many diseases are biochemical in nature and functional changes will often predate or exceed a structural change in tissue or organs.  PET imaging uses radiopharmaceuticals known as "tracers" to obtain images.  PET tracers will mimic natural sugars, water, proteins, and oxygen found in the human body.  Tracers are injected into a patient and will then collect in various tissues and organs.  The PET system then takes a time-exposure of the tracer and generates an image of cellular biological activities.  PET images are used to measure many processes, including sugar metabolism, blood flow and perfusion, receptor-ligand binding rates, oxygen utilization and many other vital physiological activities.

X-Rays & Mammography

Discovered in 1895 by Wilhelm Conrad Roentgen (1845-1923, Professor of Wuerzburg University), x-rays have provided physicians with their first glimpses of internal anatomical structure without surgery since the beginning of the 20th century.  The term x-ray now applies to a broad spectrum of imaging techniques, all of which utilize x-rays to provide diagnosis imaging information.  An x-ray image is produced when a small amount of radiation passes through the body striking an image receptor such as film, an image intensifier or a digital detector.  This creates a "shadow" of the area through which the radiation has passed.

Ultrasound

Ultrasound uses high-frequency sound waves that are converted into diagnosis information using a hand-held transducer passed over an imaged area.  The resulting ultrasound is the reflection of the sound waves as they collide with the anatomy being studied.  Non-radioactive in nature, ultrasound is used extensively on OB-GYN procedures and is most commonly associated with fetal imaging.   Nassau Radiologic Group (NRAD) has established one of the largest Level II obstetrical ultrasound practices in the country, staffed by Board Certified radiologists with Fellowship training in high risk obstetrics.  Sono hysterosalpingography is offered for the work up of infertility.

Bone Densitometry (DEXA Scanning)

Bone Densitometry (Dexa Scanning) studies are currently performed at our Garden City, Manhasset and Lakeville offices.  These examinations use specially designed equipment to determine if patients have osteoporosis and require treatment.  Examination is commonly performed in less than 20 minutes.
