Body Imaging focuses on all areas of the body except the head, neck and spine, using techniques such as body CT, MRI, ultrasound, conventional X-ray, arthrography and image-guided biopsy. Body imaging radiologists specialize in the diagnosis and radiological treatment of various abdominal, renal, liver and pancreatic diseases.

Breast Imaging services include mammography, breast ultrasound, breast MRI, galactography, needle localization, aspiration, and ultrasound-guided, MRI-guided breast biopsy or stereotactic breast biopsy. Our radiologists are dedicated to delivering comprehensive services using state-of-the-art digital technology housed in the Kitty Degree Breast Health Center, a Breast Imaging Center of Excellence (second in the state of Louisiana, first in North Louisiana).

Interventional Radiology involves the use of minimally invasive tools and techniques to treat diseases with significantly less trauma and recovery time, and costs less than traditional surgery. Using various imaging techniques, our interventional radiologists guide small instruments such as catheters (tubes that measure just a few millimeters in diameter) through the body to diagnose and treat diseases. Interventional radiology procedures are categorized as vascular and non-vascular. Vascular techniques include angiography, angioplasty, endovascular stenting, embolization and thrombolytic therapy. Non-vascular procedures include biopsies, drainage of abscesses/cysts, feeding tube placement, vertebroplasty, myelograms, anthrograms, paracentesis, thoracentesis, diagnostic therapeutic, and radio frequency ablation.

Neuroradiology is a subspecialty of radiology focusing on the diagnosis and characterization of diseases of the central nervous system, head and neck. Neuroradiologists use a wide range of techniques, such as carotid/cerebral angiography, CT, discogram, MRI, lumbar puncture, myelography, ultrasound and fluoroscopy. This subspecialty also includes Interventional Neuroradiology, which allows for the diagnosis and treatment of vascular abnormalities, such as aneurysms and other vascular malformations within the brain, without surgery.

Musculoskeletal Radiology uses technology like MRI, CT, radiography, fluoroscopy, and ultrasound, coupled with expertise to assist referring physicians in the diagnosis and management of their patients with musculoskeletal disorders. This subspecialty is comprised of imaging and diagnosis of diseases or injuries involving the musculoskeletal system, including imaging of muscles, bones, joints and their components (cartilage, tendons and ligaments).
