Neurointerventional radiology / invasive radiology are a special branch of radiology that uses imaging techniques to identify the nature of a problem. The imaging techniques can include X-rays, CT, MRI and ultrasound for guidance. The technology not only detects but with the help of it, the doctors can perform many invasive procedures. The particular branch of physicians is also called a Neurointerventional radiologist, who performs surgeries without making a surgical incision. These types of treatments without surgery are also known as vascular intervention or vascular radiology. Interventional Diagnostic treatments have evolved and are very much helpful in providing minimum risk to the patients and a very less hospital stay. Also, there will be no scar as a result of these invasive procedures. The person's hospital stay is also very minimal. Neurologists can treat a broad range of disorders due to this. Some of them include Stroke, Brain aneurysms, and other abnormal blood vessels, cardiovascular diseases, certain type of seizures and benign and malignant tumors. The technique uses a pencil-thin tube which will be inserted into the body, and the patient is treated at the source of the disease. Since only a puncture hole is all that is required, the recovery time for undergoing such procedures is also very minimal, and the patient can get back to his normal activities without any discomfort.
