Computed tomography (CT) scans give physicians detailed images from inside the body for diagnosing injury and disease. CT scans use digital technology with a rotating x-ray to create, cross-sectional images of the body. Organs and systems examined include the lungs, liver, kidneys, pancreas, pelvis, extremities, brain, spine and blood vessels. 

Diagnostic radiology at Altru Hospital and Altru Main Clinic provides quality x-rays. Our diagnostic services include exams in fluoroscopy, portables, C-arm, trauma and routine radiography. All services are available 24 hours a day, seven days a week.

Dual x-ray absorptiometry (DEXA) measures bone mineral density (BMD). DEXA is a relatively easy procedure with low radiation exposure. DEXA scanning focuses on two main areas: the hip and the spine.

DEXA scans often help to diagnose osteoporosis. A DEXA scan can measure the BMD at one site which can help predict fractures at other sites.

Interventional radiology uses catheters and imaging equipment to diagnose and treat medical problems. While this is usually an invasive procedure, it is much safer and easier for patients than surgery. Often, conditions can be diagnosed and treated on an outpatient basis using interventional radiology.

Neuroradiology is the x-ray study of the nervous system. Specialized scans of the head and spinal cord are done using Magnetic Resonance Imaging (MRI). 

MRI uses computer-controlled radio waves and a large magnet to generate images of the body's internal organs and tissues. MRI is a non-invasive procedure used in diagnosing many medical conditions, most commonly neurological disorders, musculoskeletal problems and cancer.

Digital mammography provides patients with the highest quality of care in the prevention and early detection of breast cancer.

• Improved clarity and flexibility: The radiologist can enhance the picture by adjusting brightness, contrast and focus on specific areas of interest.
• Enhanced reliability: Digital mammograms give a clearer picture on a high resolution monitor, meaning fewer patients are called back for additional pictures.
• Fast turnaround: The picture is visualized in seconds.
• Reduced wait time: The radiologist does not have to leave the room to develop film, thus eliminating wait time. 

Compared to surgery, stereotactic breast biopsy is faster and less painful, has fewer complications, requires minimal recovery time and needs only local anesthesia.

• Safer and less invasive 
• Precisely and accurately samples tissue of suspected abnormality
• Spares women the discomfort and scarring associated with surgical biopsy

If the radiologist reading your mammogram recommends a breast biopsy, discuss this alternative with your physician.

Breast MRI is used in the management of breast cancer. Breast MRI allows physicians to better diagnose breast cancer in patients who are high risk and with a family history. This technology also benefits patients with implant complications. Additionally, it helps physicians more accurately treat breast cancer, providing better long-term results for the patient.

Although breast MRI is a great technology, mammography and breast ultrasound are used for regular check-ups. Breast MRI is reserved for patients with specific high risk situations. 

Nuclear medicine uses the injection of "radiopharmaceuticals" to study organ function. Almost all organs can be imaged. Bones, heart and lungs are most commonly scanned.

After a patient has been given the radiopharmaceutical, he or she lies on an imaging table and is scanned by a "gamma camera." These tests are usually painless and simple to perform, with very minimal radiation exposure. 

Most nuclear medicine exams are for diagnostic purposes, however, a few treatments may be used in this form of radiology.   

Ultrasound uses sound waves to produce an image or photograph of an organ, body tissue or baby. Ultrasound services at Altru include OB/Gyn, abdominal, breast and prostate biopsies, neonatal head and hips, arterial, carotid and other venous ultrasounds.
