The term SRS stands for Stereotactic Radiosurgery. It’s important to know that SRS treats various medical conditions, like tumors and vascular malformations. The name ‘radiosurgery’ might confuse you, but SRS is a non-invasive treatment that uses radiation.

History and Development of Radiosurgery

The idea of stereotactic radiosurgery started with Lars Leksell, a Swedish neurosurgeon, in the 1950s. It was first for treating certain disorders and neurological conditions. Over time, SRS has grown, thanks to tech and imaging advancements, becoming a key treatment for many diseases.

The history of SRS includes big steps, like the Gamma Knife’s introduction. Today, SRS is a key treatment option. It offers patients a non-invasive and effective choice instead of traditional surgery.

The Science Behind Stereotactic Radiosurgery

Stereotactic radiosurgery targets tumors and abnormalities with radiation therapy. It uses high doses of radiation to treat specific areas. This method aims to damage only the targeted area, not healthy tissues nearby.

How Targeted Radiation Works

Targeted radiation is key to stereotactic radiosurgery. It combines multiple radiation beams to focus on the tumor. This approach protects surrounding tissues by delivering a high dose only to the tumor.

Precision and Accuracy in Treatment

Stereotactic radiosurgery is known for its unmatched precision and accuracy. It uses imaging tests like MRI and CT scans to map the treatment area. This detailed map helps plan the treatment, ensuring the radiation hits the target exactly.

Stereotactic Mapping and Imaging

Stereotactic mapping is vital in the treatment process. It creates a three-dimensional map of the area to be treated. This map guides the radiation delivery, making the treatment both precise and effective.

Imaging Technique	Role in Stereotactic Radiosurgery
MRI	Provides detailed images of soft tissues, helping to define the target area.
CT Scan	Offers accurate information on the size and shape of the tumor and its relation to surrounding structures.
Angiography	Helps in visualizing blood vessels and assessing vascular structures near the treatment site.

Is Stereotactic Radiosurgery Actually Surgery?

The word “surgery” usually makes us think of operating rooms and cuts. But stereotactic radiosurgery is different. It uses radiation to target specific areas, like in the brain, without making cuts.

Non-Invasive Nature of the Procedure

Stereotactic radiosurgery is non-invasive. It doesn’t need to open the skull or make cuts. Instead, it uses technology to aim radiation beams at the target area from many angles.

Comparison to Traditional Surgical Approaches

Stereotactic radiosurgery is different from traditional surgery. Traditional surgery means cutting into the body, which can lead to infections and longer recovery times. Radiosurgery, on the other hand, is done in one session, with little downtime and fewer risks.

Why It’s Called “Surgery” Without Incisions

The term “surgery” in stereotactic radiosurgery means it’s precise and targeted, like traditional surgery. But it doesn’t need cuts. The SRS medical meaning shows it treats conditions with surgery-like accuracy, but without cuts.

Pain and Discomfort During Stereotactic Radiosurgery

Many patients wonder about the pain during stereotactic radiosurgery. This procedure is a precise form of radiation therapy. It targets specific areas, like the brain, with little harm to healthy tissues.
