Purpose To evaluate the relative position between lumbar plexus and access corridor of minimally invasive lateral transpsoas lumbar approach, as well as the approach safety. Methods Three-dimensional fast imaging employing steady-state acquisition (3D FIESTA) sequence images of lumbar spine were obtained...
We analyzed a total of 27 patients who had both pelvic MRI-DIXON-F and CT images within one year. The median time interval and interquartile range (IQR) between the pelvic CT scan and pelvic MRI-DIXON-F scan was 20 (−90 to 70) days. For pelvic MRI-DIXON-F image, scatter plots ...
Whole-body magnetic resonance imaging (WB-MRI) is currently used worldwide for detecting bone metastases from prostate cancer. The 5-year survival rate for prostate cancer is > 95%. However, an increase in survival time may increase the incidence of bone metastasis. Therefore, detecting bone...
Cho et al (2009) reported the results of a systematic review and meta-analysis of imaging strategies for LBP without indications of serious underlying conditions. Inclusion criteria were randomized controlled trials that compared immediate, routine lumbar imaging (or routine provision of imaging findings...
VENC: velocity encoding; FOV: field-of-view; SENSE: sensitivity encoding; TE: echo time; TR: repetition time. Image processing The PC-MRI images were post-processed using in-house software, “Flow” [8]. The software executes a semi-automatic segmentation algorithm for CSF and blood vessels...
Note the visibility of the entire length of the spinal cord on the 3D inverted MIP images and ready visibility of the dorsal nerve root ganglia of the brachial and lumbar plexuses. Focal high-signal lesions over the left chest are due to an acneiform rash on the skin. 展开 ...
homogeneous and uniform fat suppression in our breast imaging and post contrast T1 fat sat thoracic and lumbar spine images. They also help in obtaining better pre-scan shim values on abdominal/pelvic imaging of very thin patients. These pads are most definitely a worthwhile investment into image...
Non-Invasive MRI of BCSFB Function: Application to the Human Brain at 3T A proof-of-application MRI study was performed in three healthy volunteers to investigate method feasibility in the human brain at 3T. 3D FLAIR structural images clearly identify the main locus of CP tissue within the lat...
Limitations of conventional MRI for PNST diagnosis include non-specific signal alterations on T1W and T2W images and variable contrast enhancement [21, 22]. Because the presence of fat within and around nerve structures significantly obscures pathologic signal intensity on T2W imaging, use of ...
An MRI image demonstrating distribution of local anesthetic after lumbar plexus block. MRI en que se muestra la distribución del anestésico local después del bloqueo del plexo lumbar. Literature A CT or MRI scan with contrast should be performed before lumbar puncture to exclude a focal cer...
