Interventional Radiology Tests
A variety of minimally invasive treatments are carried out by the medical speciality of interventional radiology (IR) under the direction of imaging techniques including ultrasound, computed tomography, magnetic resonance imaging, and x-ray fluoroscopy. Through extremely small cuts or openings in the body, IR carries out both therapeutic and diagnostic treatments. Infusing an imaging contrast agent into a hollow structure, such a blood artery or duct, or performing an image-guided biopsy of a tumour are examples of diagnostic IR operations that are meant to aid in making a diagnosis or directing subsequent medical therapy. Therapeutic IR techniques, in contrast, offer direct therapy; examples include catheter-based medication administration and medical device implantation (e.g., stents),angioplasty of constricted structures, etc.
The key advantages of interventional radiology procedures are that they may use tiny needles and wires to enter a body orifice or small incision and access the deep tissues of the body. Compared to open surgeries, this lessens the hazards, discomfort, and recovery time.
Real-time viewing also enables pinpoint direction to the anomaly, improving the accuracy of the surgery or diagnosis. These advantages must be evaluated against the added dangers associated with radiation exposure, including the development of cataracts and cancer, as well as the hazards of not having rapid access to internal structures in the event of bleeding or a perforation.
