Radiologist examining MRI or CT Scan report


Columbia Radiology offers a full menu of radiology services in friendly, convenient locations. You'll have access to the most current technology and image-guided therapies along with radiologists and technicians who perform and interpret more than 500,000 procedures and scans each year. Our radiologists have experience diagnosing a range of diseases and conditions, often catching important details that might otherwise go unnoticed.

We have several state-of-the-art facilities located throughout Manhattan and Westchester, with many of our services offered on a walk-in basis. Our commitment to expert, personal care means that your radiologist will partner with your physician to provide you with quick, accurate results. We are here to answer your questions about exams and procedures.

Our Services

Bone Density Scan (DEXA)

A bone density scan helps determine if you have osteoporosis. The most advanced form of bone densitometry, DEXA, is a non-invasive and painless X-ray test of the spine, hip, and arm bones that gives doctors precise information about the amount of calcium in the bones.

Computed Tomography (CT)

Computed tomography (CT) is an X-ray exam that uses specialized equipment to produce cross-sectional pictures of the body. CT is critical to the rapid diagnosis of many conditions including traumatic injuries, stroke, heart disease, infections, and cancer. It is also used to plan and guide procedures and to monitor the effectiveness of therapy for diseases such as cancer and infection.


Fluoroscopy is an X-ray imaging technique doctors use to observe both the structure and function of organs in real time, including the bladder, kidneys, reproductive organs, and parts of the gastrointestional (GI) tract. During the exam, a specialized X-ray machine called a fluoroscope creates a sequence of images that are projected onto a monitor, enabling doctors to capture a moving image of your organs. To obtain the best images your doctor may have you take a liquid contrast agent (often barium) by mouth, intravenously, or via an enema. This agent enhances the clarity and definition of the area being examined.

Interventional Radiology

Interventional radiologists use image guidance and minimally-invasive tools to perform procedures that would otherwise require open surgery. The imaging techniques—X-ray, ultrasound, CT, and MRI—enable interventional radiologists to view specific areas inside the body and to place catheters, insert medical devices, and treat specific areas of disease. Most of the time, this means that our patients go home on the day of their procedure with a Band-Aid instead of an incision. Our interventional radiologists perform thousands of procedures each year, including treatment for cancer, fibroids, enlarged prostate, varicose veins, and kidney disease. Our HHT Center provides comprehensive, multidisciplinary treatment for hereditary hemorrhagic telangiectasia.

Lung Cancer Screening

Early detection through low-dose computed tomography (LDCT) can find lung cancer at a stage when it is still curable through treatment. We offer lung cancer screening to eligible smokers or those who have smoked heavily in the past. Talk to your doctor about the benefits and risks of lung cancer screening to decide whether screening is right for you.

Lung Cancer Screening Program

Magnetic Resonance Imaging (MRI)

Magnetic resonance imaging (MRI) uses strong magnetic fields and radio waves to produce cross-sectional images of organs and internal structures in the body. Doctors use MRI to diagnose brain and nervous system disorders; problems affecting tendons, cartilage, ligaments, and bone marrow; inflammatory bowel disease and other gastrointestinal disease; and heart problems, such as congenital heart disease. MRI is also used to diagnose cancer and monitor response to treatments for cancer and other conditions.

Mammography and Breast Imaging

We provide the highest quality screening and diagnostic breast care in supportive, private, and comfortable settings. We use the most advanced imaging technologies available, including tomosynthesis (also called "3D" mammography), contrast-enhanced mammography, breast ultrasound, MRI, and biopsy. A radiologist (imaging doctor) with expertise in breast imaging evaluates every exam.

Musculoskeletal Imaging and Pain Management

We use advanced imaging techniques to diagnose arthritis, trauma, sports injuries, rheumatologic conditions, and bone tumors. Our musculoskeletal radiologists also perform image-guided procedures and minimally invasive pain management therapies—including barbotage, Morton's neuroma injections, steroid injections, and platelet rich plasma—that often provide an alternative to surgery.

Positron Emission Tomography (PET)

PET is a type of “nuclear imaging” test. In this group of imaging procedures, the patient receives a small injection of a radioactive “tracer” that is absorbed by the organs and tissues being examined. This powerful non-invasive imaging tool can reveal abnormal molecular activity caused by many forms of cancer and diseases and disorders of the brain and heart. PET can show these changes before they become visible on imaging tests such as CT and MRI, which show structural but not biochemical changes. PET is often combined with CT in a dual-purpose PET-CT imaging device. The scans are done simultaneously and can be viewed separately or as a single, overlapping "fused" PET-CT image. 


Ultrasound imaging (also called sonography) uses sound waves to create images of internal organs, structures, and tissues. Diagnostic ultrasound is used help determine the causes of pain, swelling, and infection in the body's internal organs. It can also be used to guide procedures, such as a breast biopsy. Musculoskeletal ultrasound is used to diagnose orthopedic and sports injuries by looking at real-time images of muscles, tendons, ligaments, nerves, and cartilage.

X-Ray and Fluoroscopy

We offer X-Ray services on a walk-in basis at our midtown Manhattan and Tarrytown locations.
