The purpose of our educational exhibit is to: 1.
illustrate the normal anatomy and normal CT/MR-US fusion appearance of the lumbar spine with a special focus on facet joints,
nerve roots and sacroiliac joints.
describe a systematic technique forfusion-guided interventional procedures around the spine
interventional procedures around the spine,
such as facet joint injections,
nerve root blocks and sacroiliac joint injections,
in a low back pain condition,
were performed under fluoroscopy or CT guidance (fig.
that are considered the gold standard to achieve accurate guidance of the needle but expose the patient to a significant radiation dose,
even considering the possibility to repeat the therapeutic treatment over time. Ultrasound suffers from poor visualization of the...
Imaging findings OR Procedure Details
We present proceduresperformed with a newly developed echo-navigator (Masmec,
Italy) which enables probe-oriented or needle oriented procedures,
integrating the virtual tracking with fusion imaging (fig.4). The patient is placed in a prone position on the bed,ready to perform the fusion imaging infiltration. Step 1Ultrasound equipment and setting We used a newly 'ECO-NAV’ fusion imaging system (MASMEC,
Italy),equipped with needle-tip sensors and 3-5 MHz convex probe withintegrated...
Real-time fusion-guided needle insertion resulted a valuable procedure,
which allows for a quick,
safe and effective injection around lower spine.This procedure,using a single MRI data-set and avoiding radiation exposure,
itcan be of specific benefit in younger patients with chronic lower back pain,
in whom repeated injections are necessary over time .
