How Interventional Radiology Changing Pain Management?
By Alnoor Diagnostic Centre | Shadman, Lahore
A Revolution in Treatment That Most Patients in Lahore Have Never Heard Of
When most people think about treating chronic pain, they think about two options — medication or surgery. Take tablets to manage the symptoms, or undergo an operation to address the underlying problem. For decades, these were the primary tools available. But a third approach has been quietly transforming pain management across the world, offering patients targeted, minimally invasive treatments that are more precise than medication and far less disruptive than open surgery.
That approach is interventional radiology — and at Alnoor Diagnostic Centre in Shadman, Lahore, we provide interventional radiology services that bring this advanced treatment capability directly to patients across the city.
What Is Interventional Radiology?
Interventional radiology — commonly abbreviated as IR — is a medical specialty that uses real-time imaging guidance to perform precise, minimally invasive procedures inside the body through tiny incisions or needle punctures rather than open surgical cuts. The interventional radiologist uses imaging technologies — fluoroscopy, ultrasound, CT, or MRI — to see exactly where their instruments are at every moment during the procedure, navigating through the body’s anatomy with a level of precision that the naked eye during open surgery cannot replicate.
The instruments used are extraordinarily small — fine needles, thin catheters, and miniature guidewires that travel through blood vessels and tissue to reach specific targets deep within the body. Through these instruments, the radiologist can deliver medication directly to a pain source, block nerves transmitting pain signals, reduce inflammation at a precise anatomical location, ablate abnormal tissue, or restore blood flow to compromised structures — all without the tissue damage, anaesthetic risk, and prolonged recovery that surgical procedures require.
How Imaging Guidance Makes the Difference
The defining feature of interventional radiology — the element that makes it fundamentally different from blind injection techniques — is real-time imaging guidance throughout every procedure. When a pain-generating structure sits deep within the spine, pelvis, or abdomen, reaching it accurately without imaging guidance is essentially impossible. A needle aimed at a facet joint, a nerve root, or a coeliac plexus without fluoroscopy or CT guidance reaches its intended target inconsistently, producing unreliable results and carrying unnecessary risk.
With imaging guidance, the interventional radiologist sees the tip of their needle in real time as it advances through tissue. They confirm its exact position relative to the target structure before any medication or treatment is delivered. This precision means the right structure receives the right treatment in the right dose — consistently, reproducibly, and safely. It transforms pain procedures from approximate to exact.
Conditions Treated Through Interventional Radiology
Spinal pain and disc disease — Back pain affecting the lumbar and cervical spine is one of the most common and most debilitating conditions in Lahore. When disc herniation, nerve root compression, or facet joint degeneration causes severe, persistent pain that has not responded to physiotherapy and oral medication, interventional radiology offers targeted solutions. Image-guided nerve root blocks deliver anti-inflammatory medication directly to a compressed nerve root, reducing inflammation and pain with a specificity that systemic oral medication cannot achieve. Facet joint injections address pain arising from degenerated spinal joints. Epidural steroid injections treat widespread nerve root inflammation causing radiating leg or arm pain. Each procedure is performed under fluoroscopic or CT guidance with the patient experiencing minimal discomfort and no surgical recovery.
Cancer-related pain — Patients with abdominal and pelvic malignancies frequently experience severe pain from tumour involvement of the coeliac or hypogastric nerve plexuses — networks of nerves that transmit pain from the abdominal and pelvic organs. Coeliac plexus neurolysis — performed under CT guidance — delivers a chemical agent directly to this nerve network, interrupting pain transmission and providing lasting relief that dramatically reduces the need for high-dose opioid medication. This procedure changes quality of life profoundly for cancer patients whose pain was previously inadequately controlled.
Joint pain — Image-guided joint injections deliver corticosteroid, hyaluronic acid, or platelet-rich plasma precisely into the joint cavity under ultrasound or fluoroscopic guidance. Whether the target is a knee, hip, shoulder, or sacroiliac joint, imaging guidance confirms needle placement within the joint before any injection is made — ensuring the treatment reaches its intended target rather than the surrounding soft tissue. This precision dramatically improves outcomes compared to landmark-guided blind injections.
Vertebroplasty and kyphoplasty — Osteoporotic vertebral fractures cause severe, debilitating spinal pain in elderly patients. Vertebroplasty and kyphoplasty are image-guided procedures in which medical-grade bone cement is injected directly into a fractured vertebral body under fluoroscopic guidance, stabilising the fracture and providing rapid, lasting pain relief. Many patients who were bedbound with vertebral fracture pain walk comfortably within days of the procedure.
Radiofrequency ablation — Radiofrequency ablation uses heat generated by radio waves to disable specific nerves transmitting chronic pain signals. Under image guidance, a fine electrode is positioned precisely at the target nerve — commonly the medial branch nerves supplying the facet joints of the spine — and radiofrequency energy is applied, interrupting pain transmission for months to years. This procedure provides lasting relief for patients with chronic facet joint pain who have responded temporarily to diagnostic nerve blocks.
Why Interventional Radiology Is Changing Pain Management
Traditional pain management relies heavily on systemic medication — oral or injected drugs that circulate throughout the entire body to reach their intended target. The systemic approach means that every organ and tissue receives the medication, not just the pain source. Side effects accumulate with prolonged use. Tolerance develops. Pain control becomes progressively less effective over time as doses escalate.
Interventional radiology delivers treatment directly and precisely to the pain source — bypassing the systemic route entirely. A fraction of the drug dose achieves a greater local effect than a much larger systemic dose, with minimal side effects because the rest of the body is not exposed. This targeted approach is more effective, better tolerated, and more sustainable for long-term pain management than systemic medication alone.
For patients who have been told they are not surgical candidates due to age, medical comorbidities, or the nature of their condition, interventional radiology frequently offers a treatment pathway that neither medication nor surgery could provide. It fills a critical gap in the pain management spectrum.
