Interventional Radiology

Interventional Radiology (IR) provides minimally invasive image-guided diagnosis and treatment of diseases in every organ system of the body. IR uses the most modern, least invasive technique available in order to minimize risk to the patient and improve health outcomes. These procedures are usually performed using needles and narrow tubes called catheters, rather than by making large incisions into the body as in traditional surgery. Many conditions that once required open surgery can now be treated non-surgically by interventional radiologists. By minimizing the physical trauma to the patient, non-surgical interventions can reduce infection rates and recovery time, as well as shorten hospital stays.


Ultrasound is an imaging technique that uses high frequency sound waves to produce pictures of body organs/tissues and blood vessels. Since it does not use any radiation, it is ideal for almost any type of exam including studies of the abdomen, pelvis, breast, neck, arms, legs, and pregnant women. A registered ultrasound technologist performs the ultrasound exam. The body is scanned with a handheld transducer enhanced with gel. The transducer is gently rubbed across the body and images are taken by the technologist and viewed on a small screen. After the exam is completed, it is reviewed and interpreted by a radiologist. A complete report is sent to the referring physician. The exam can take approximately 30 minutes to one hour to complete. Ultrasound is performed at the main hospital, Crittenton Outpatient Imaging Center at Crittenton Medical Plaza – Auburn Hills, Crittenton Barclay Imaging Center on Barclay Circle in Rochester Hills, and Crittenton Medical Plaza – Oxford. A physician’s request or referral is needed.

Magnetic Resonance Imaging (MRI)

MRI: Magnetic Resonance Imaging

Magnetic Resonance Imaging is a radiation-free, non-invasive procedure that uses strong magnetic fields to create images of body tissues. MRIs are used for diagnosis on nearly every area of the body. The MRI scan typically lasts 30-45 minutes.

Appointments may be scheduled by calling Ascension Crittenton Central Scheduling at 844-462-2462.
Hours of operation are Monday – Friday, 7 a.m. – 10 p.m., Saturday and Sunday 8 a.m. – 9:30 p.m. Same or next-day appointments are available. A physicians order is required.


The Department of Radiology offers Fluoroscopic examinations. Fluoroscopy involves viewing anatomy during a motility procedure, like a barium studies, allowing the Radiologist to view the procedure as a “motion picture”. This includes studies such as upper GI, lower GI, and esophagrams. This modality can also be utilized with intravenous contrast media injections into vessels to assess interruptions of blood flow. Fluoro studies are performed at the main hospital and Crittenton Barclay Imaging Center. A physician’s request or referral is needed.

Nuclear Medicine

Nuclear Medicine is a very safe way to detect abnormalities within the body. Patients are given an agent called a radionuclide by a Nuclear Medicine Technologist, which is injected into an arm, swallowed in the form of a pill or inhaled into the lung. It contains a very small quantity of safe radioactive material, which can be detected by a special camera. Imaging usually starts as early as 15 minutes or up to 4-6 hours later. Although it is considered a painless test, it can take awhile to complete the exam. A Nuclear Medicine Technologist will let you know the timing of the test and any special instructions. It is important to know that the radioactive material leaves the body shortly after the test is completed. Nuclear Medicine studies are performed at the main hospital only. A physician’s request or referral is needed.


Disease processes often begin with functional changes at the cellular level. That’s why our specialists combine images from a Positron Emission Tomography (PET) and a CT scan to provide incredibly detailed information regarding the anatomy of hyper-metabolic activity in your tissues and organs. This scan is usually ordered for cancer staging and treatment follow up.

The Department of Radiology also offers state of the art CT scanning with the recent addition of our Philips MX 8000 16 multi-slice scanner. The CT images are obtained by imaging the body in “slices” and displaying them for the Radiologist as a cross section. Some of these exams are done after the administration of oral and/or intravenous contrast media and some are done without either, depending on the exam ordered by your physician. CT studies are performed at the main hospital and the WellPointe Imaging Center in Rochester Hills. A physician’s request or referral is needed.

Digital Mammography

Breast cancer strikes more than 180,000 women each year, claiming more than 40,000 lives each year. At Ascension Crittenton, we are committed to early detection through mammography and patient education.

Our skilled radiologists and technologists are certified in mammography. During a mammogram, each breast is carefully positioned and compressed to increase image clarity. A mammogram usually takes just a few minutes, but may take up to an hour. The test is done under the supervision of a board-certified radiologist specializing in mammography.

If a lump is discovered, Ascension Crittenton provides quick response. Our radiologists are immediately available to provide a diagnostic ultrasound to give patients the answers they need. We also provide specially trained nurses who can teach proper breast self-examination technique. Each first-time mammography patient is offered a one-on-one session with the nurse.

Mammography is performed at the main hospital, Crittenton Outpatient Imaging Center at Crittenton Medical Plaza – Auburn Hills, Crittenton Barclay Imaging Center on Barclay Circle in Rochester Hills, and Crittenton Medical Plaza – Oxford. A physician’s request or referral is needed.

We now offer state-of-the-art digital 3D Mammography (Tomosynthesis). Also known as 3D Tomo, this is one of the most powerful diagnostic tools available for the early detection of breast cancer.  3D mammography is now available at two convenient Ascension Crittenton locations: Crittenton Medical Plaza — Center for Breast Health at 2251 N. Squirrel Road, Suite 201, Auburn Hills and Crittenton Barclay Imaging Center, 355 Barclay Circle, Suite B in Rochester Hills. A physician referral is required for a mammogram, but for more information please call 844-462-2462.


Computer-Aided Tomography

Also known as a CT Scan or CAT Scan. Ascension Crittenton’s ultra-fast scanners use x-rays to quickly produce computerized images of the body in slices. This allows your doctor to scan multiple sections and perform a rapid evaluation – an invaluable advantage for patients with a trauma to the head, spine or abdomen.

CT scans are performed at the main hospital and Crittenton Wellpointe Imaging Center. A physician request or refferal is needed.

Bone Densitometry

Conveniently offered at three outpatient locations (Oxford, Squirrel Road and Well Pointe), this is a non-invasive and painless evaluation that will assess the health and strength of your bones. This procedure will also help your doctor detect if you are at risk of low bone mass or osteoporosis.

General Radiology

Radiography, better known as X-ray, is commonly used to obtain images of the internal structure (bones) and organs. Performed by our friendly and skilled technologists, this procedure may provide your doctor with information about the presence or absence of disease, a bone fracture or other conditions they may be looking to rule out.

X-Ray services are done at the main hospital, Crittenton Squirrel Outpatient Imaging Center, Crittenton Barclay Imaging Center , Crittenton Oxford Imaging/ Diagnostic Center and Crittenton Wellpointe Imaging Center. A physician request or referral is needed.

Tumor Ablation

Click here for the Tumor Ablation Program page.

Ascension Crittenton is now offering Tumor Ablation, a minimally invasive option for thorough destruction of cancerous tumors in nearly any area of the body. An outpatient procedure, ablation is similar to a needle biopsy but is performed under CT Scan and/or ultrasound guidance for tumor visualization. Tumor ablation can be performed either with heat or cold, optimally using microwave or cryotechnology. Cryoblation can also be used to treat benign tumors, such as breast fibroadenomas, chest/abdominal wall desmoids, and endometriosis of the abdominal wall.

Image-guided tumor ablation can treat many cancerous tumors as thoroughly as other treatment options with less pain, less risk, faster recovery time, and lower recurrence rates. Tumor ablation can also be an option for high-risk patients such as those with obesity, poor heart/lung status, or those with one kidney. The program is led by Peter Littrup, MD, pioneering Interventional Radiologist and globally recognized scientist in medical imaging. Three patients have already been treated with tumor ablation at Ascension Crittenton – 2 small kidney tumors and a large adrenal metastasis. Dr. Littrup has treated over 1,000 patients with lung, liver, kidney and soft tissue tumors.
