Bone densitometry, sometimes called a DEXA Scan or Bone Mineral Density Test, is an x-ray that measures bone density. It is primarily used to determine the strength of your bones and whether you have or are likely to develop osteoporosis. The lower the calcium and mineral content in your bones, the greater the chance that you could fracture a bone in a fall.

Bone densitometry is quick and painless. Usually, you lie down on a special table, and your spine, lower arm, and hip are scanned. You will have to change positions during the scan.

Your results will be compared to the bone densities of healthy young adults and to adults of your own age and ethnicity. If you have been tested before, your last scan results will also be used to see if you have gained or lost bone mass.

Bone Densitometry Hours:

Monday, Tuesday, Wednesday, Friday
9 am – 4 pm

9 am – 6:30 pm

Bone Densitometry services are also available at our Croton and Dobbs Ferry locations.

A CT (computed tomography), or CAT, scan uses x-rays to take detailed pictures inside the body. Each picture, or slice, is put together digitally to create a 3-dimensional image. It can be used on almost any body part, and it is often used to pinpoint a cause for unexplained pain.

CT scans are painless. They are faster to perform than some other tests, like MRIs. Some CTs require contrast, which may be given by mouth or as an injection or enema. This contrast helps the radiologist better see certain body structures during the test. If you have questions about the contrast material ordered as part of your CT, please check with your healthcare provider.

In addition to a 64-slice GE VCT CT scanner, Phelps has a 128-slice Siemens SOMATOM Definition Edge CT scanner.  The scanner’s high-speed imaging is very low dose and creates a very high image quality. It has has advanced capabilities for cardiac diagnostics and all types of angiograms, as well as a fluoroscopy function for biopsies.

CT Scan Hours:

Monday – Friday
7 am – 6 pm

8 am – 1 pm

The Breast Imaging Center at Phelps offers two different kinds of mammograms to help catch breast cancer early. We use digital mammogram technology that produces clear, sharp images and can zoom in to find small changes that may be cancerous. We also use Computer Aided Detection (CAD) software. It works as a second set of eyes to help our radiologists when making a diagnosis.

Our mammogram techs strive to make your experience a positive one. While some women may find the exam somewhat uncomfortable, our advanced, digital mammogram systems generally use less pressure than older machines. Each image takes only a few seconds to obtain.

Phelps offers two types of mammograms:

  • 2D mammogram creates a flat, or two-dimensional, image of the breast. Phelps offers 2D mammograms at the Breast Imaging Center and at all radiology department locations.
  • 3D mammograms, or breast tomosynthesis, convert digital breast images into thin slices. These slices are stacked together digitally to make up a 3-dimensional model of the breast. Some experts believe this type of mammogram is more accurate and may find cancer earlier than a 2D mammogram. 3D mammograms are performed the same way as 2D mammograms.

Many insurance plans now cover 3D mammograms. Please check with your insurance provider. We offer 3D mammograms at the Breast Imaging Center, as well as at Phelps Radiology in Croton-on-Hudson and Phelps Radiology in Dobbs Ferry.

Phelps also offers stereotactic biopsy, ultrasound-guided core biopsy, needle localization, ultrasound-guided fine needle aspiration (FNA), breast ultrasound, Breast MRI and MRI-guided breast biopsy.

Mammography Hours:

Monday, Thursday
7 am – 7:30 pm

Tuesday, Wednesday
7 am – 5 pm

7 am – 4 pm

8 am – 1 pm

Mammography services are also available at our Croton and Dobbs Ferry locations.

Magnetic Resonance Imaging (MRI) exams use magnetic fields and radio waves to produce detailed images. An MRI may be ordered for many different conditions, from bone problems to brain issues to diseases of various organs.

MRI is painless, although MRI machines can be quite loud. (We provide hearing protection.) Some MRIs require contrast, which may be given by mouth or as an injection. This contrast helps the radiologist better see certain body structures during the test. If you have questions about the contrast material ordered as part of your MRI, please check with your healthcare provider.

With both 3T and 1.5T MRIs, the Phelps MRI Center offers advanced diagnostic capabilities, including enterography, featuring excellent visualization of the small bowel and elastography, which enables non-invasive detection of liver disease by measuring soft tissue stiffness. The MRI Center also has the latest technology for prostate, breast and cardiac imaging.

The Phelps MRI Center offers:

  • Faster scanning and a quieter atmosphere than conventional MRIs
  • A spacious MRI that is more open than traditional MRIs, allowing the head to be outside of the machine for many types of exams
  • Music and decorative mood lighting of the patient’s choice
  • High-resolution images with optimal detail
  • Specialized board certified radiologists — quick report turn-around and expert diagnosing

MRI Hours:

Monday – Friday
6:30 am – 9 pm

Saturday, Sunday
8 am – 4 pm

Nuclear medicine uses small amounts of radioactive materials to learn more about how an organ or body system is functioning. Sometimes, nuclear medicine is used together with MRI or X-ray.

During a nuclear medicine test, a very small amount of a radioactive substance, called a tracer, is injected. The tracer attaches to the organ or system being studied. The rate at which the tracer attaches can give valuable information about the type of problem you might have. Sometimes, nuclear medicine is used to treat diseases, like hyperthyroidism.

Nuclear Medicine Hours:

Monday – Friday
8 am – 5 pm

Ultrasound imaging, or sonography, uses sound waves to take pictures of the body. Ultrasound can be used to examine nearly any body part or structure.

Ultrasound is painless, although firm pressure may be needed for the technologist to see certain organs or structures inside your body. A water-based gel is applied to the skin to help produce high-quality images during the test.

Ultrasound Hours:

Monday, Tuesday, Wednesday, Friday
7:30 am – 6 pm

7:30 am – 7 pm

8 am – 1 pm

This service is also available at our Croton and Dobbs Ferry offices.

An x-ray is used to create a picture of the inside of your body in shades of black and white. X-rays are used for many purposes, including examining areas of pain, monitoring diseases or to see if treatments are working.

Phelps offers state-of-the-art digital x-ray services. Digital x-rays are faster to obtain than traditional films, so they expose patients to less radiation. They also allow doctors to send, receive, and examine x-rays on a computer.

X-Ray Hours:

Monday, Tuesday, Wednesday, Friday
8 am – 6 pm

8 am – 7 pm

8 am – 1 pm

X-Ray services are also available at our Croton and Dobbs Ferry locations.
