This article presents and describes an outpatient treatment for prostate cancer using focal laser ablation. Laser catheter placement is guided by MRI-ultrasound fusion imaging in a fashion similar to prostate needle biopsy. Treatment is monitored in real-time with a thermal probe, placed adjacent to the laser fiber.

Source: Muto, A., et al. Ablation of a Neuronal Population Using a Two-photon Laser and Its Assessment Using Calcium Imaging and Behavioral Recording in Zebrafish Larvae. J. Vis. Exp. (2018) In this video, a two-photon laser ablation procedure is demonstrated, enabling the selective destruction of fluorescent neurons in agarose-immobilized zebrafish larvae. High-resolution imaging before and after the procedure confirms efficient neuronal damage, as observed by the absence of fluorescence.
FAQs
Heat, cold, electrical current, laser energy, and chemicals can each be used to produce controlled injury in abnormal tissue. Although the agents differ, the intended result is selective destruction, removal, or isolation of the targeted area. Choosing among these options depends on the condition being treated and the need to limit injury to nearby healthy structures.
Accurate targeting determines whether the abnormal tissue receives enough treatment while surrounding structures remain protected. This balance is central because ablation deliberately creates tissue injury, yet its clinical value depends on limiting unintended damage. In practice, catheter-based or image-guided approaches help clinicians focus treatment on the disease source rather than treating a larger area than necessary.
Ablation procedures can provide a localized treatment option when disease is confined to a specific area. Depending on the condition, clinicians may use minimally invasive techniques or surgery, with catheter-based and image-guided approaches offering alternatives to more extensive operations. Their potential advantages include targeting the disease source, preserving healthy tissue, and reducing symptoms.
A typical approach begins with identifying the abnormal tissue and selecting a suitable energy source or chemical agent. The clinician then reaches the target through a catheter-based, image-guided, or surgical route and applies controlled treatment to destroy, remove, or isolate it. The procedure’s success depends on precise positioning, appropriate treatment delivery, and suitable patient selection.
Clinical applications include cardiac arrhythmias, certain tumors, chronic pain, and other localized conditions. The treatment target differs by disease: abnormal cardiac tissue may be treated to address rhythm problems, while localized tumor or pain sources may be targeted to reduce disease-related effects. These applications reflect the broader principle of treating a condition at its source.
Outcomes depend substantially on whether clinicians can accurately identify and reach the abnormal tissue, select an appropriate treatment approach, and determine whether the patient is suitable for the procedure. When targeting is effective, treatment may reduce symptoms, preserve healthy tissue, or avoid more extensive surgery. Results therefore vary with the condition and its location.
