​​​​Bone densitometry is used to assess your bone health and fracture risk. This handout explains how the exam works, how to prepare for it, what to expect during the exam and how to get your results.

Interventional Radiology (IR) is one of the most exciting and advanced fields in medicine, but it is also one of the least well known. IR uses the latest in imaging technology to perform minimally invasive procedures throughout the body. Procedures that once required large incisions, general anesthesia, and days or weeks in the hospital can now be done on an outpatient basis with an incision so small that it does not require stitches.

Please select a procedure from the following list:

CT imaging—sometimes called CAT scanning—is a noninvasive test that helps physicians diagnose and treat medical conditions. CT combines special X-ray equipment with sophisticated computers to produce multiple images or pictures of the inside of the body. These cross-sectional images of the area being studied can then be examined on a computer monitor or printed.

A mammogram is an imaging test to find breast cancer. It uses X-ray to take images of the breasts. There are two types of mammograms: Screening mammograms are used to find breast cancer in women who do not have breast symptoms or complaints. Diagnostic mammograms are used to look for the cause of a symptom, such as a lump in the breast.

​Fluoroscopy is an imaging technique that uses X-ray to obtain real-time moving images of the internal structures of a patient through the use of a fluoroscope. A video camera allows the images to be recorded and played on a monitor. Please choose from the list below to learn more about the various fluoroscopy procedures: 

An X-ray (radiology exam) is a medical test that produces images (pictures) of a part of a body. These images help doctors diagnose health conditions. Doctors use bone X-ray to view and assess broken bones, skull fractures and spine injuries. Bone X-ray may also be used to guide orthopedic surgery (surgeries that involve bones, joints, ligaments or muscles), treat sports-related injuries and diagnose advanced forms of bone cancer. 

Magnetic resonance imaging (MRI) is a noninvasive medical test that helps physicians diagnose and treat medical conditions. MRI uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures.

Our Diagnostic Imaging team uses computed tomography, or CT, to produce a series of detailed, three-dimensional images of parts of the body. The CT is a painless, fast scan that uses both special x-ray equipment and computers to produce images that often can provide more detailed information than regular X-rays.

A CT scan can produce detailed images of organs, bones, soft tissues and blood vessels. CT scans are used to diagnose conditions such as cancer, musculoskeletal disease and trauma to certain areas of the body. The detailed results of a CT can eliminate or reduce the need for surgical biopsies and exploratory surgery.

Our diagnostic imaging staff uses magnetic resonance imaging (MRI) to develop detailed pictures of the inside of your body without the use of invasive techniques or x-ray radiation. The tests are performed using a strong magnetic field and radio waves to produce a clear, detailed view of a patient’s internal organs and tissues. An MRI is painless and extremely safe.

An MRI can be used to assess a variety of situations – from knee or head injuries to tumors or blood and vessel disorders. MRIs have proven valuable for the diagnosis of a broad conditions in all parts of the body, including heart and vascular disease, stroke, and cancer, to name a few. In many cases, other imaging procedures, such as ultrasound or CT, may detect a problem and MRI is then used to evaluate that problem further.

A nuclear medicine examination produces images that can help a physician diagnose a specific disease or disorder, or capture images of infections or tumors in specific organs. A patient is given a small amount of a radioactive compound that localizes in specific body organ systems. This compound gives off energy, which a special camera can detect and use to produce an image that can be viewed on a computer. Nuclear medicine exams are commonly used to evaluate blood flow and function of the heart, respiratory and blood flow to the lungs, kidney functions and the presence of cancer, among others. The radiation levels that a patient receives are generally comparable to that of a standard X-ray exam.

Ultrasound is a medical imaging technique that uses high-frequency sound waves similar to the sonar that dolphins and submarines use. Ultrasound imaging is used to study many of the body’s organs by using high frequency sound waves instead of radiation. When sound waves are recorded, they are immediately displayed on a monitor in real time. Although most individuals are familiar with an ultrasound as the device that allows them to see a picture of an unborn child, physicians also use ultrasound to see images and movement inside the patient’s body, including the body’s blood flow, and the size and function of many internal organs including the heart, pancreas, liver, bladder and kidneys.

Vascular and interventional radiology (VIR) specialists deliver minimally invasive image-guided treatments for numerous conditions occurring throughout the body.

VIR specialists utilizes many non-surgical, minimally invasive treatments as alternatives to open surgical procedures. VIR radiology procedures are generally easier for the patient because they involve small incisions, minimal pain and shorter recovery times.

VIR radiologists use their expertise in X-rays, computed tomography (CT) scans, ultrasound, and other medical imaging technology to guide small instruments, such as catheter tubes, through the blood vessels or other pathways to treat medical conditions, rather than open surgery.

Examples of vascular and interventional radiology procedures include vertebroblasty, kyphoplasty, radio frequency ablation of tumors, angiography, balloon angioplasty and stenting to open clogged blood vessels, uterine fibroid embolization, spinal pain injections, and needle biopsy, among others.
