 Role
of magnetic resonance imaging in entrapment and compressive
neuropathy?what, where, and how to see the peripheral nerves on the
musculoskeletal magnetic resonance image: part 2. Upper extremity
Kim, Sungjun., et al. ? The diagnosis of nerve entrapment and
compressive neuropathy has been traditionally based on the clinical and
electrodiagnostic examinations. As a result of improvements in the
magnetic resonance (MR) imaging modality, it plays not only a
fundamental role in the detection of space-occupying lesions, but also a
compensatory role in clinically and electrodiagnostically inconclusive
cases. Although ultrasound has undergone further development in the past
decades and shows high resolution capabilities, it has inherent
limitations due to its operator dependency...
Is
the body-coil at 3 Tesla feasible for the MRI evaluation of the painful
knee? A comparative study
Lutterbey, G., et al. ? The purpose of this study was to compare the
in-built body coil of the 3.0-Tesla (T) scanner with a dedicated surface
coil of a 1.5 T system regarding knee imaging. We performed an
intraindividual prospective clinical trial on 17 patients with knee pain
using magnetic resonance imaging (MRI) at 1.5 and 3.0 T systems equipped
with identical gradient systems. Proton-density-weighted turbo spin echo
sequences with the same spatial resolution and comparable contrast
parameters were used. A quantitative measurement of signal to noise
ratio (SNR), relative contrast (RC) and contrast to noise ratio (CNR)
between muscle and bone marrow was performed...
Reliability
of B-mode ultrasonography for abdominal muscles in asymptomatic and
patients with acute low back pain
Asghar Norasteh M.S.P.T., et al. - The purpose of this methological
study was to develop a reliable method for measuring transversus
abdominis, rectus abdominis, external oblique and internal oblique
muscles in asymptomatic human subjects and patients with acute low back
pain (ALBP)...The results of this study indicate that the measurement of
abdominal muscle thickness with B-mode ultrasonography can be performed
reliably even in patients with ALBP...
Comparison
of musculoskeletal ultrasound practices of a rheumatologist and a
radiologist
G. Raftery, et al. - Conclusion: MSUS performed by the rheumatologist
was predominantly requested by rheumatologists to aid diagnosis of
synovial and tendon inflammation and to guide injections, while MSUS
performed by the radiologist was predominantly requested by orthopaedic
surgeons to aid diagnosis of structural pathology. Curriculums in MSUS
designed for rheumatologists may need to place appropriate emphasis on
the identification of synovial and tendon inflammation, and injection
guidance...
The
Diagnosis of Meniscus Tears: The Role of MRI and Clinical Examination
Ryzewicz, Mark MD, et al. - Magnetic resonance imaging (MRI) and
clinical examination are tools commonly used in the diagnosis of
meniscus tears. It has been suggested routine MRI before therapeutic
arthroscopy for clinically diagnosed meniscus tears will reduce the
number and cost of unnecessary invasive procedures...
Reproduction
of the Lumbar Lordosis: A Comparison of Standing Radiographs Versus
Supine Magnetic Resonance Imaging Obtained with Straightened Lower
Extremities
Marianne Logtholt Andreasen MSc, et al. - This study investigates
whether it is possible to reproduce the lumbar lordosis in the upright
position during magnetic resonance imaging (MRI) by positioning the
patient supine with straightened lower extremities and investigates
intra- and interexaminer reliability of measurements of the lumbar
lordosis on radiographs and MRI...Conclusion: The findings of this study
show that lumbar lordosis in the upright position can be reproduced by
positioning the patient supine with straightened lower extremities...
MR
imaging of osteochondral grafts and autologous chondrocyte implantation
Trattnig, S., et al. - Surgical articular cartilage repair therapies for
cartilage defects such as osteochondral autograft transfer, autologous
chondrocyte implantation (ACI) or matrix associated autologous
chondrocyte transplantation (MACT) are becoming more common. MRI has
become the method of choice for non-invasive follow-up of patients after
cartilage repair surgery...
