Beyond Anatomy: Fat-Suppressed MR and Molecular Imaging of Spinal Pain Generators
Radiol Clin North Am. 2024 Mar;62(2):247-261. doi: 10.1016/j.rcl.2023.09.005. Epub 2023 Nov 13.ABSTRACTSpine pain is highly prevalent and costly, but evaluation with clinical features and anatomic imaging remain limited. Fat-suppressed MR imaging and molecular imaging (MI) may help identify inflammatory, lesional, and malignant causes. Numerous MI agents are available, each with advantages and disadvantages. Herein, FDG PET, prostate-specific membrane antigen (PSMA), bone radiotracers, and others are highlighted. No specific pain MI agents have been identified, but mechanisms of key agents are shown in video format, and th...

Epub 2023 Nov 11.ABSTRACTCerebrospinal fluid (CSF) leak can cause spontaneous intracranial hypotension (SIH) which can lead to neurologic symptoms, such as orthostatic headache. Over time, imaging techniques for detecting and localizing CSF leaks have improved. These techniques include computed tomography (CT) myelography, dynamic CT myelography, cone-beam CT, MRI, MR myelography, and digital subtraction myelography (DSM). DSM provides the highest sensitivity for identifying leak sites and has comparable radiation exposure to CT myelography. The ...

Percutaneous Treatment and Post-treatment Management of CSF Leaks and CSF-Venous Fistulas in Spontaneous Intracranial Hypotension
Radiol Clin North Am. 2024 Mar;62(2):333-343. doi: 10.1016/j.rcl.2023.09.003. Epub 2023 Oct 20.ABSTRACTSpontaneous intracranial hypotension (SIH) is a treatable cause of orthostatic headaches secondary to pathologic loss of cerebrospinal fluid (CSF) from the subarachnoid space. SIH has several known pathologic causes including dural tears from disc osteophytes, leaks emanating from nerve root sleeve diverticula, and CSF-venous fistulas (CVFs). Depending on the type of leak, surgical repair or endovascular techniques may be options for definite treatment. However, epidural blood patching (EBP) remains first-line therapy for...

Endovascular Embolization Techniques for Cerebrospinal Fluid-Venous Fistula in the Treatment of Spontaneous Intracranial Hypotension
Radiol Clin North Am. 2024 Mar;62(2):345-354. doi: 10.1016/j.rcl.2023.10.006. Epub 2023 Nov 8.ABSTRACTCerebrospinal fluid-venous fistula (CVF) is an important cause of spontaneous intracranial hypotension (SIH), a condition characterized by low cerebrospinal fluid (CSF) volume and orthostatic headaches. The pathogenesis of CVF is thought to be direct connection of the spinal dura to one or more veins in the epidural space, allowing unregulated flow of CSF into the venous system. Herein, we provide a comprehensive review of the endovascular management of CVF in patients with SIH. We also focus on the various techniques and ...

The Anatomy, Technique, Safety, and Efficacy of Image-Guided Epidural Access
Radiol Clin North Am. 2024 Mar;62(2):199-215. doi: 10.1016/j.rcl.2023.09.006. Epub 2023 Nov 1.ABSTRACTEpidural steroid injections have demonstrable efficacy and safety in treatment of radicular pain syndromes; transforaminal access has greater evidence of efficacy than interlaminar approaches. The interventionalist must understand epidural and foraminal anatomy and imaging to insure delivery of medication to the target, the ventral epidural space at the site of neural compression. This obligates pre-procedural planning. When performed with appropriate risk mitigation strategies, epidural injections by either access are saf...

Imaging of Discogenic and Vertebrogenic Pain
Radiol Clin North Am. 2024 Mar;62(2):217-228. doi: 10.1016/j.rcl.2023.10.003. Epub 2023 Nov 11.ABSTRACTChronic low back pain is a major source of pain and disability globally involving multifactorial causes. Historically, intervertebral disc degeneration and disruption have been associated as primary back pain triggers of the anterior column, termed "discogenic pain." Recently, the vertebral endplates have been identified as another possible pain trigger of the anterior column. This "endplate-driven" model, defined "vertebrogenic pain," is often interconnected with disc degeneration. Diagnosis of vertebrogenic and discogen...
