Through the advanced and specialized practice of radiology, RAPA has the unique power to see and do more than ever thought possible in an outpatient setting. Using extraordinary technology, minimally invasive interventional techniques, our imaging modalities render powerful diagnostic information that in turn gives hope for a more beneficial therapeutic outcome.

At RAPA, our ability to utilize technology to foster greater physical, spiritual and mental well being has inspired us to never stop searching for new ways to improve the lives of those we serve.


A computed tomography (CT) scan makes use of computer-processed combinations of many X-ray images taken from different angles to produce cross-sectional (tomographic) images (virtual “slices”) of specific areas of a scanned object, allowing the user to see inside the object without cutting.


Magnetic Resonance Imaging (MRI) is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body in both health and disease. MRI scanners use strong magnetic fields, radio waves, and field gradients to generate images of the inside of the body.


Diagnostic Ultrasound is a diagnostic imaging technique based on the application of ultrasound. Ultrasonic images also known as sonograms are made by sending pulses of ultrasound into tissue using a probe. It is used to see internal body structures such as tendons, muscles, joints, vessels and internal organs.


Endovenous laser therapy treats varicose veins using an optical fiber that is inserted into the vein to be treated, and laser light, normally in the infrared portion of the spectrum, shines into the interior of the vein. This causes the vein to contract, and the optical fiber is slowly withdrawn.


Angiography is a medical imaging technique used to visualize the inside of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers. This is done by injecting a contrast agent into the blood vessel and imaging using X-ray (fluoroscopy), computed tomography (CT), or magnetic resonance (MR).


Bone Densitometry, also called Dual-energy X-ray absorptiometry (DXA) is a means of measuring bone mineral density (BMD). Two X-ray beams, with different energy levels, are aimed at the patient’s bones. When soft tissue absorption is subtracted out, the BMD can be determined from the absorption of each beam by bone. Dual-energy X-ray absorptiometry is the most widely used and most thoroughly studied bone density measurement technology. The DXA scan is typically used to diagnose and follow osteoporosis.


Mammography is the process of using low-energy X-rays to examine the human breast, which is used as a diagnostic and screening tool. The goal of mammography is the early detection of breast cancer, typically through detection of characteristic masses and/or microcalcifications.


Nuclear medicine is a medical specialty involving the application of radioactive substances in the diagnosis and treatment of disease. Nuclear medicine, in a sense, is “radiology done inside out” or “endoradiology” because it records radiation emitting from within the body rather than radiation that is generated by external sources like X-rays. In addition, nuclear medicine scans differ from radiology as the emphasis is not on imaging anatomy but the function and for such reason, it is called a physiological imaging modality.


Positron emission tomography (PET) is a nuclear medicine, functional imaging technique that is used to observe metabolic processes in the body. The system detects pairs of gamma rays emitted indirectly by a positron-emitting radionuclide (tracer), which is introduced into the body on a biologically active molecule. Three-dimensional images of tracer concentration within the body are then constructed by computer analysis. In modern PET-CT scanners, three dimensional imaging is often accomplished with the aid of a CT X-ray scan performed on the patient during the same session, in the same machine.


Interventional Radiology is a sub-specialty of radiology providing minimally invasive image-guided diagnosis and treatment of diseases in every organ system. Although the range of procedures performed by interventional radiologists is broad, the unifying concept behind these therapies is the use of the most modern, least invasive technique available in order to minimize risk to the patient and improve health outcomes. RAPA Interventional Radiology services include biopsy, pain relief treatments, aneurysm occlusion, TIPS, and more.

RAPA is committed to providing our patients with the best diagnostic imaging tools available including digital mammography, dedicated breast ultrasound, breast MRI, and computer-aided detection.

Additionally, our imaging tools facilitate accurate needle biopsies when you need definitive answers.



If performed annually as recommended, screening mammography is the key to detecting breast cancer early and saving lives. Women 40 years of age and older with no symptoms of breast disease, should schedule their screening mammogram appointments annually. A physician referral is not required for this exam. However we must have the name of your physician to send your results.

Why annually? Compared to annual exams, if women get their mammograms every other year, 30% of breast cancers will go undetected. One third fewer women will die from breast cancer if they get annual mammograms. Additional information can be found Here on the Mammography Saves Lives website.

Your screening mammogram consists of routine views that will be reviewed after you leave. If your screening mammogram shows a possible abnormality, you will be called back for a diagnostic mammogram (see below). Most of these will turn out fine, often due to overlapping tissue looking like a possible abnormality.


While a screening mammogram is encouraged each year for women who do not have significant breast symptoms, your doctor may order a diagnostic mammogram if you are experiencing a problem. A diagnostic mammogram should be ordered by your doctor for any worrisome lump, changes in the breast skin, focal pain, spontaneous nipple discharge (clear or bloody), or if you have a personal history of breast cancer. It is also recommended for your first mammogram after a biopsy or procedure. Diagnostic mammography may also be performed if your screening mammogram demonstrates a possible abnormality. Patients with a benign appearing finding on their mammogram may be asked to return in 6 months for a diagnostic mammogram to assess stability.

The type and number of mammographic views taken will be customized to your situation. Any additional mammographic views and ultrasound will be done at the time of your diagnostic mammogram visit.



Breast MRI is a sophisticated technology that uses a computer, magnetic field and radio waves instead of x-rays to produce images of the soft tissues in the body. This non-invasive procedure helps our board-certified physicians to better evaluate the breast in special circumstances. When used in conjunction with screening and diagnostic mammography, it can provide valuable information for the detection and characterization of breast disease.

If MRI is used, it should be in addition to, not instead of, a screening mammogram. While an MRI is more likely to detect cancer than a mammogram, it may still miss some cancers that a mammogram would detect. MRI also has a higher false positive rate (where the test finds things that turn out to not be cancer), which would result in unneeded biopsies and other tests if performed on a large portion of women.



An ultrasound-guided biopsy is a technique most often used to guide a breast biopsy when a breast abnormality is visible on ultrasound.

You will lie on your back or turn slightly to the side. The ultrasound probe is used to locate the lesion. Local anesthetic is injected to ensure that you will be comfortable. The radiologist will then create a small nick in the skin through which the biopsy needle will be inserted, and several samples of tissue will be obtained for evaluation. A tiny metallic marking clip may be left at the biopsy site so that it can be easily relocated for surgery or follow up, if needed. We will provide you with an ice pack and post biopsy care instructions.


A stereotactic breast biopsy allows for a needle biopsy to be performed on lesions which are better seen on mammography than on ultrasound. This type of biopsy utilizes x-ray images (mammograms) of the breast tissue to guide the biopsy needle to the area of interest. Stereotactic biopsies are most commonly performed on tiny breast calcifications; but can also be utilized on breast masses in certain situations.

This minimally invasive procedure requires you to be positioned lying face down on a specially designed table used specifically for breast biopsies. Your breasts are positioned through an opening in the table and placed in compression (less than we use for a regular mammogram). We will then clean the skin and inject a local anesthetic. A tiny incision less than a quarter of an inch is made to allow insertion of the biopsy needle. The radiologist will remove several samples of tissue through this incision. A tiny metallic marking clip may be left at the biopsy site so that it can be easily relocated for surgery or follow up, if needed. We will provide you with an ice pack and post biopsy care instructions.


An MRI-guided biopsy is guided in real-time by magnetic resonance (MR) imaging and is useful when an abnormality is best seen on MRI.

You will be positioned face down on your stomach and your breasts will be positioned into a cushioned opening containing a special breast-imaging coil. Using computer software, the radiologist will determine the position and depth of the lesion for biopsy. Local anesthetic will be injected into the breast to numb it and contrast material is given in your vein. When the tissue sampling is complete, a tiny metallic marking clip may be left at the site of biopsy, so it can be easily located for surgery or future follow up, if needed.



Breast ultrasound is a non-invasive tool using high-frequency sound energy used to evaluate specific areas of concern – such as a breast lump felt by a patient or physician or an area of concern seen on a mammogram. Breast ultrasound does not replace the need for mammography in women old enough to have mammograms.
