Feb

Overview

Interventional radiology uses imaging to guide minimally invasive procedures. It treats vascular and non vascular conditions. It reduces recovery time compared to open surgery.

Procedures

Common procedures include embolization angioplasty and ablation. These techniques manage bleeding tumors and vascular disease. They are performed under imaging guidance for precision.

Imaging Guidance

Fluoroscopy CT and ultrasound guide interventions. Real time imaging improves safety and outcomes. Multimodality imaging supports complex procedures.

Patient Selection

Careful patient selection and multidisciplinary planning are key. Risk assessment and informed consent are required. Follow up imaging monitors treatment success.

Digital Subtraction Angiography DSA

Overview

DSA acquires images before and after contrast injection and subtracts them to highlight vascular anatomy and pathology with high temporal resolution.

Technique

Catheter based contrast delivery high frame rate acquisition and subtraction processing are key. Roadmapping aids interventions.

Clinical Uses

Cerebral peripheral and visceral angiography for diagnosis and endovascular therapy planning.

Limitations and Safety

Invasive procedure with contrast and radiation risks. Requires vascular access expertise and perioperative care.

Overview

Charles Dotter pioneered percutaneous transluminal angioplasty and image guided catheter techniques that launched interventional radiology.

Key Contributions

Developed catheter based methods to dilate stenotic vessels and introduced minimally invasive vascular therapies under imaging guidance.

Impact on Medicine

Dotter’s innovations reduced the need for open surgery and expanded therapeutic options across vascular and oncologic care.

Honors and Legacy

Recognized as a founder of interventional radiology with lasting influence on endovascular therapy and device development.
