Meet Dr. Lea

Dr. William Lea, MD

Dr. William Lea, MD, RPVI is a board-certified, Vascular & Interventional Radiologist. His clinical practice is divided equally between seeing patients in consultation in the office setting and performing minimally-invasive, image-guided procedures when appropriate. His extensive training and expertise allows him to provide comprehensive patient-centered care for a wide variety of conditions.

Dr. Lea is a native of Nashville, TN and graduate of both Harvard University and Vanderbilt University School of Medicine. He completed two years of general surgery residency at Indiana University, four years of diagnostic radiology residency at Indiana University, and a comprehensive fellowship in Vascular & Interventional Radiology at the Medical College of Wisconsin in Milwaukee, WI, completing his medial training in 2015.

After completion of his training, Dr. Lea continued in academic medicine for over 4 years as an Assistant Professor of Vascular & Interventional Radiology at the Medical College of Wisconsin where he trained. During this time, he was involved in numerous clinical research projects, academic publications, and speaking engagements both nationally and internationally with a primary focus on minimally-invasive therapies for primary and secondary musculoskeletal malignancies. He is a founding member of the Society of Interventional Oncology (SIO).

In the fall of 2024, Dr. Lea will be joining Cape Radiology Group, serving as the Section Chief of Interventional Radiology. CRG provides services throughout southeast Missouri, western Kentucky, and southern Illinois.

What Is Interventional Radiology?​

Interventional radiology (IR) is a medical specialty that uses minimally invasive techniques to diagnose and treat various conditions inside the body. It combines image-guided procedures with the expertise of radiologists to provide precise and targeted treatments.

Interventional radiologists are medical doctors who have completed additional specialized training in radiology and interventional procedures. They use a range of imaging techniques, such as X-rays, fluoroscopy, ultrasound, computed tomography (CT), and magnetic resonance imaging (MRI), to visualize the inside of the body and guide their procedures.

Interventional radiology procedures are performed using thin, flexible tubes called catheters, which are inserted into the body through small incisions or natural openings, such as blood vessels or the gastrointestinal tract. These catheters allow the interventional radiologist to deliver treatment directly to the affected area or perform diagnostic tests without the need for open surgery.

Some common interventional radiology procedures include:

  • Angiography: Imaging of blood vessels to diagnose and treat conditions like blockages, aneurysms, or abnormal blood vessel formations.
  • Angioplasty and stenting: Widening of narrowed or blocked blood vessels using a balloon and placement of a stent to help keep the vessel open.
  • Embolization: Blocking off blood vessels to stop bleeding, shrink tumors, or treat abnormal blood vessel growths.
  • Biopsy: Obtaining tissue samples for diagnosis by inserting a needle or catheter into the affected area under imaging guidance.
  • Drainage: Inserting catheters or tubes to drain fluid collections, such as abscesses or blocked bile ducts.
  • Thrombolysis: Dissolving blood clots using medications or mechanical devices to restore blood flow.
  • Ablation: Using heat to destroy tumors, such as liver or kidney tumors.
  • Transjugular intrahepatic portosystemic shunt (TIPS): Placement of a shunt between liver blood vessels to treat complications of liver cirrhosis.

These are just a few examples of the wide range of interventional radiology procedures available. The field continues to evolve, with new techniques and technologies constantly being developed to improve patient care and outcomes. Interventional radiology offers minimally invasive alternatives to traditional surgery, reducing risks, hospital stays, and recovery time for patients.

What makes Interventional Radiology (IR) different from other specialties?​

Interventional radiology (IR) is distinct from other medical specialties in several ways:

  1. Minimally invasive approach: One of the key differences is the emphasis on minimally invasive techniques. IR procedures are typically performed through small incisions or natural body openings, avoiding the need for traditional open surgery. This approach offers numerous advantages, including reduced pain, shorter hospital stays, faster recovery times, and decreased risks compared to more invasive procedures.

  2. Image-guided procedures: Interventional radiologists use various imaging techniques, such as X-rays, fluoroscopy, ultrasound, CT scans, and MRI, to guide their procedures in real-time. This allows for precise visualization and accurate placement of instruments or devices within the body. By relying on imaging, interventional radiologists can often diagnose and treat conditions with greater accuracy and effectiveness.

  3. Multidisciplinary collaboration: Interventional radiology often involves close collaboration with other medical specialties. Radiologists work alongside surgeons, oncologists, neurologists, gastroenterologists, and other specialists to develop comprehensive treatment plans for patients. This multidisciplinary approach ensures that the most appropriate and effective treatment options are considered, combining the expertise of different specialists to achieve optimal outcomes.

  4. Broad range of procedures: Interventional radiology covers a wide range of procedures that can be diagnostic, therapeutic, or palliative in nature. This versatility allows interventional radiologists to treat various conditions throughout the body, including blood vessel disorders, cancer, liver disease, kidney disease, and many others. They can perform procedures such as angioplasty, embolization, biopsy, ablation, and more, depending on the specific needs of each patient.

  5. Evolving field: Interventional radiology is a dynamic and rapidly evolving field. Technological advancements, such as improved imaging modalities, miniaturized instruments, and new treatment devices, continually expand the capabilities of interventional radiologists. They adapt to and adopt new technologies and techniques, staying at the forefront of medical innovation to provide the best possible care for their patients.

Overall, interventional radiology combines the precision of imaging with minimally invasive procedures to diagnose and treat a wide range of conditions. Its focus on innovation, collaboration, and patient-centered care sets it apart from other medical specialties.
