Update on recent developments in imaging of inflammation in osteoarthritis: a narrative review
AbstractSynovitis is an important component of the osteoarthritis (OA) disease process, particularly regarding the “inflammatory phenotype” of OA. Imaging plays an important role in the assessment of synovitis in OA with MRI and ultrasound being the most deployed imaging modalities. Contrast-enhanced (CE) MRI, particularly dynamic CEMRI (DCEMRI) is the ideal method for synovitis assessment, but for several r easons CEMRI is not commonly performed for OA imaging in general. Effusion-synovitis and Hoffa-synovitis are commonly used as surrogate markers of synovitis on non-contrast-enhanced (NCE) MRI and have been used in ...

Percutaneous spine biopsy: reaching those hard-to-reach places
 AbstractCancer is a leading cause of death, with the spine being the most common site for skeletal metastasis. The spine is also a site for primary malignancy, such as sarcoma and chordoma, as well as non-neoplastic pathologies. An accurate diagnosis of spinal neoplastic diseases is crucial in determining appropriate management. With the advent of personalised oncology, the need to establish a definitive histopathologic diagnosis to guide management is more important than ever. Percutaneous biopsy has proven to be safe and efficient in establishing a reliable histopathologic diagnosis. The spine, however, can be a chall...

Facets of facet joint interventions
This article discusses fluoroscopic and CT-guided intraarticular FJ injections, medial branch (MB) radiofrequency ablation (RFA), and lumbar facet synovial cyst (LFSC) aspiration, rupture, or fenestration. Additionally, the article will highlight medial branch blocks (MBBs) utilized to diagnose facet-mediated pain and to predict outcomes to RFA. (Source: Skeletal Radiology)

Discitis-osteomyelitis: optimizing results of percutaneous sampling
AbstractVertebral discitis-osteomyelitis is an infection of the spine that involves the intervertebral disc and the adjacent vertebral body but may also extend into the paraspinal and epidural soft tissues. If blood cultures and other culture data fail to identify a causative microorganism, percutaneous sampling is indicated to help guide targeted antimicrobial therapy. Despite limited supporting evidence, withholding antimicrobial therapy for up to 2  weeks is recommended to maximize microbiological yield, although literature supporting this recommendation is limited. During the procedure, technical factors that may impr...

Lower extremity peripheral nerve pathology: Utility of preoperative ultrasound-guided needle localization before operative intervention
AbstractHistorically, the use of ultrasound (US) in the management of peripheral nervous system (PNS) pathology has been limited to diagnostic confirmation or guidance for interventional injections. This technical case series will demonstrate the utility and versatility of preoperative US-guided needle localization for the excision of lower extremity neuromas and other pathology of the PNS. Five patients with symptomatic lower extremity PNS tumors were retrospectively reviewed. This case series corroborates the technical nuances of localizing lower extremity neuromas by US-guided needle and wire placement prior to operativ...

Rationale for fluoroscopic guidance in spine injections
AbstractSpine injections are commonly performed in the treatment of back pain. The purpose of this article is to review the current literature surrounding image guided spine injections focusing on scenarios where fluoroscopic guidance can be advantageous in addition to discussing similarities among the different modalities.

Intra-arterial injection of particulate corticosteroids: mechanism of injury
AbstractMechanism of neurologic complications after epidural spinal injections (ESI) of particulate steroids at the cervical spine include intrathecal injection, epidural hematoma, direct spinal cord injury, and brain stem or cord infarction due to an arterial spasm or inadvertent intra-arterial injection of particulate steroids. At the lumbar spine, there is evidence that a spinal cord infarction secondary to an inadvertent intra-arterial injection of particulate steroids through a transforaminal approach is the leading mechanism.Variations in the arterial supply of the spinal cord help to understand how a lumbar ESI may ...

Arterial embolization during percutaneous vertebroplasty resulting in bilateral renal infarcts and ischemic colitis
AbstractThis case report documents an arterial embolic event that occurred during vertebroplasty for a pathological compression fracture of T12 in a 54-year-old female with known metastatic breast carcinoma. A CT angiogram performed after the procedure demonstrated cement migration into the aorta, both kidneys, and the inferior mesenteric artery and its branches, with ischemic colitis involving the descending colon and sigmoid colon. A CT scan 4  months post-procedure demonstrated resolution of the colitis. Neovascularity and cortical destruction in malignant bone lesions are thought to contribute to arterial cement leak....

An update on epidural steroid injections: is there still a role for particulate corticosteroids?
AbstractEpidural steroid injections (ESIs) play an important role in the multifaceted management of neck and back pain. Corticosteroid preparations used in ESIs may be considered “particulate” or “non-particulate” based on whether they form a crystalline suspension or a soluble clear solution, respectively. In the past two decades, there have been reports of rare but severe and permanent neurological complications as a result of ESI. These complications have principa lly occurred with particulate corticosteroid preparations when using a transforaminal injection technique at cervical or thoracic levels, and only rar...

Spine injections: the rationale for CT guidance
Abstract Back pain is one of the most common medical problems and is associated with high socioeconomic costs. Imaging-guided spinal injections are a minimally invasive method to evaluate where the back pain is originating from, and to treat patients with radicular pain or spinal stenosis with infiltration of corticosteroids. CT-guided spine injections are a safe procedure, characterized by precise needle placement, excellent visualization of the relevant anatomical structures, and low radiation exposure for the patient and the interventional radiologist. In this review article, the variety of applications of CT-guided ...
