Ultrasound is a safe procedure that uses reflected sound waves instead of radiation. The images are obtained with a small ultrasound probe passed over the patient that both sends and receives sound waves. The waves passing through the body are reflected back and computer processed to generate an image. Ultrasound is commonly used to image pregnancy, the abdomen, and pelvis. Special measurements of blood flow can also be obtained to evaluate narrowing of neck (carotid) or leg artereis and veins. Ultrasound is also used to guide needle for biopsies including breast biopsies and for directing placement of catheters (small tubes) into blood vessels. All of WRS radiologists are doctors with dedicated training in ultrasound.

PET CT Radiology
Positron Emission Tomography (PET) is a type of nuclear imaging using small amounts of radioisotopes for characterization of a variety of conditions and disease. PET is commonly used to determine the extent or stage of cancer and to determine the response to cancer treatment. It is also used for cardiac or heart imaging and for evaluation of the some brain diseases. When the PET scanner is physically joined with a CT scanner for better image quality this is known as a PET/CT.

PET/CT is performed as an outpatient procedure and requires the intravenous injection of a small amount of radioactive material. After a small amount of time, patients are scanned and both the PET and CT data is obtained. As with many imagng studies, it is important for good imaging that the patient remain still during the scan.

Magnetic Resonance Imaging (MRI)

 Magnetic Resonance Imaging

Magnetic Resonance Imaging (MRI) is a common exam used to evaluate many disease processes and musculoskeletal injuries. MRI images are obtained using a combination of radio waves and magnetic fields. Special coils are placed which act like antennas to pick up signal in the area being scanned. The MRI patient must remain still and will be given instructions by the technologist throughout the examination. The MRI units can be noisy so earphones for music or ear plugs are often used. Sometimes an injection of mri dye is needed to help the exam.

The MRI evaluation of blood vessels is an exam is referred to as magnetic resonance angiography or MRA.

Other MRI exams include Breast MRI used for breast cancer detection and diagnosis as well as screening high risk patients.

Interventional Radiology

WRS employs seven fellowship trained interventional radiologists who perform image guided procedures for the diagnosis and treatment of a range of medical condition. Some of the more common procedures are kyphoplasty for the treatment of spinal compression fractures, angiography-angioplasty-and stent placement for peripheral vascular disease, central venous access including pic lines and dialysis catheters, aortic stent grafts, ultrasound and CT guided biopsies, and uterine artery embolization for the treatment uterine fibroids. The majority of the procedures are preformed within the hospitals that we serve. In addition, at our office we perform sclerotherapy and laser vein ablation for treatment of spider and varicose veins.

Uterine Fibroid Embolization (UFE)

Uterine fibroid embolization (UFE) is an image guided minimally invasive treatment for benign tumors of the uterus known as fibroids. This procedure is performed by specially trained interventional radiologists as a non-surgical way to reduce the symptoms related to fibroids. UFE is much less invasive than open surgery done to remove uterine fibroids or the whole uterus (hysterectomy). No surgical incision is needed and patients can usually resume normal activities much earlier than if they had a hysterectomy.

Computed Tomography (CT)

Computed Tomography
Computed Tomography (CT), also known as CAT scan, is used for the evaluation of a wide range of symptoms and diseases. The patient lies on a moving table while cross sectional images are created by an x-ray tube spiraling at high speed around the body. Some exams may require oral contrast or the injection of a CT contrast dye. The CT images are generated after computer processing then sent to the Radiologist for interpretation. Some of the newest CT applications include CT colonography to screen for colon cancer, coronary artery calcium scoring to determine heart attack risk factors, and CT coronary angiography to look at the blood vessels supplying the heart.

Varicose Vein Treatment

Varicose Vein TreatmentWRS Interventional Radiologists John Tomashek, M.D. and James Beres, M.D. are performing outpatient Varicose Vein Treatment at the WRS Vein Center.

Varicose veins can be embarrassing and unsightly. But more than just aesthetics, varicose veins can be responsible for serious medical problems that include severe pain and skin ulceration.

Ordinarily the calf veins function to return blood to the heart through a series of one way valves which prevents blood pooling in the legs. But, as yet another unfortunate consequence of aging, these valves can malfunction producing the problem we know as varicose veins. Failure within the valves can occur thorough a variety of means but most valves fail through either normal aging or from disease such as blood clots (deep vein thrombosis). The failed valve often results in blood that pools in the leg veins, enlarging them and often creating unsightly ropey structures that are often painful.

Asthetic considerations aside, the alterations in the venous blood flow can sometimes make walking difficult. In some cases venous problems are severe enough to cause skin break down and skin ulcers.

Historically the treatment of problematic leg veins involved surgical “vein stripping” where surgeons made incisions and actually removed the problem veins. More recently, endovenous laser ablation has been used to seal the veins from the inside out. This procedure, used by skilled WRS Interventional Radiologists only requires local anesthesia and a tiny skin incision to pass the small catheter.

If you search the web for more information, most of the pages served up will be advertisements from medical practices, of which we are one. But how does one make an educated selection from so many different options and vein ablation providers?



How We’re Different From Other Providers

Laser Vein AblationWho does the procedure?
Laser treatments at Wisconsin Radiology Specialists are performed by Interventional Radiologists (real doctors with years of experience in diagnostic imaging that are specially trained to perform less-invasive image guided procedures)

What equipment do you use?
WRS physicians only use state-of-the-art ultrasound, and the best guiding catheters to treat venous disease without surgery.

Who does the ultrasound procedure?
Our WRS physicians perform all of the ultrasound procedures themselves – no outside sources are used. All of our doctors are board certified in both Diagnostic and Interventional Radiology.

What will my insurance cover?
Wisconsin Radiology specialists works directly with your insurance carrier to have all procedures pre-authorized, taking the burden off of you.



Our 3 Step Process Includes:

1. EVALUATION – WRS schedules an ultrasound evaluation to determine the source of your leg symptoms and to help determine if Laser Vein Ablation is right for YOU.

2. PREAUTHORIZATION – WRS Radiologists work with your insurance to obtain the proper approval and preauthorization.

3. PROCEDURE – WRS will schedule all of your evaluation, procedure, and follow up appointmens at one convenient location. We will work with you to ensure that your experience with us is positive and that your treatment is successful.
