“…Although US can sensitively detect incomplete soft tissue injuries [6], MRI is better suited for direct imaging of the spinal cord and the subarachnoid space due to its ability to delineate different tissue types and provide accurate identification of herniations and stenosis in the lumbar and cervical spine [9]. Moreover, MRI can be obtained in multiple planes with different weights, offering a considerable amount of information.…”

The utility of ultrasound for surgical spinal decompression

Surgery is routinely performed to decompress the spinal cord. While a number of imaging modalities are currently used in the perioperative setting of surgical spinal cord decompression including computed tomography scan and magnetic resonance imaging, ultrasound (US) usage is relatively new. Therefore, only a few studies in the literature describe its value in the perioperative setting. US is a simple, safe, rapid, non-invasive, and inexpensive modality that constitutes a potential alternative when other modalities are not suitable or unavailable. It enables surgeons to generate high-resolution real-time images that can aid in diagnosing pathologies, guiding surgeries, and evaluating surgical outcomes. This review discusses the present literature and utility of pre-, intra-, and post-operative US in patients undergoing surgical spinal decompression. We also delineate three cases in which US was utilized at King Saud University hospital, which is considered one of the first centers in our region to report the use of US to guide treatment in spine surgery.

“…However, US is useful in identifying the development of tears, abscesses, and areas of fluid collection after surgery [5,9]. It can also confirm adequate positioning of shunts as well as • US enables catheter placement in the right jugular vein in preparation for posterior cervical decompression.…”

“…These include the use of high peak voltage and tube current, as well as narrow collimation and thin sections during image acquisition. The use of thick sections with lower kernel values during reformatting can also reduce streaking (Thakkar et al 2012 ).…”

“…• Laminotomy: resection of part of the lamina • Laminectomy: resection of the whole width of the lamina • Laminectomy with facetectomy: laminectomy with resection of part of the facet joint (Thakkar et al 2012 ) Normal and expected appearances following diskectomy include high T2 signal intensity within the intervertebral disk up to 2 months following surgery, as well as disk enhancement up to 6 weeks postsurgery. Changes in the endplates simulating Modic type 1 appearance of low T1 and high T2 signal intensities may also be encountered.…”
