Imaging of acute cervical spine injuries: review and outlook
- Clinical Radiology |
|
Advances in imaging
technology have been successfully applied in the emergency trauma
setting with great benefit providing early, accurate and efficient
diagnoses. Gaps in the knowledge of imaging acute spinal injury remain,
despite a vast wealth of useful research and publications on the role of
CT and MRI...

Sonography of entrapment neuropathies in the upper limb (wrist
excluded) -
Journal of Clinical Ultrasound |
|
|
The progressive
refinement of broadband transducers with frequencies higher than 10 MHz
and improved near-field resolution has enhanced the potential of
sonography to evaluate a variety of nerve entrapment syndromes occurring
in the upper limb, such as suprascapular neuropathy in the area of the
spinoglenoid-supraspinous notch, the quadrilateral space syndrome (axillary
neuropathy), radial neuropathy in the area of the spiral groove, the
supinator syndrome... |

Sonography of the knee: Intra-articular pathology
- Journal of Clinical Ultrasound |
|
|
MRI is the
gold-standard imaging technique for evaluation of the intra-articular
structures of the knee, and the use of sonography remains controversial.
Sonography nevertheless is a useful alternative in several conditions:
Inflammatory joint diseases, where it is appropriate for early diagnosis
and follow-up of joint effusion and synovitis... |

Intense Bilateral Pectoralis Major Muscle Activity on Tc-99m MDP
Scintigraphy: The Push-up Sign
- Clinical Nuclear Medicine |
|
|
Uptake of Tc-99m MDP by
skeletal muscle may occur after strenuous physical activity and is
usually an incidental finding. The case of a 37-year-old man who
underwent bone scintigraphy for the evaluation of back pain is
presented. Although no cause for the back pain was found, delayed
imaging demonstrated bilateral symmetric Tc-99m MDP activity in the
pectoral muscles. The patient gave a history of performing upper torso
exercises 48 hours before the examination, but had no symptoms referable
to the pectoral muscles... |

Fibula Stress Fracture and Confounding Myositis Ossificans
- Clinical Nuclear Medicine |
|
|
A 26-year-old man
presented with left lower leg pain after a skiing injury. Plain
radiography was initially reported as normal at the site of the
suspected fracture but revised after the bone scan. An additional area
of calcification was described adjacent to the proximal fibula without a
conclusive diagnosis. A fibula fracture was easily apparent on Tc-99m
bone scintigraphy, and the more proximal focus of uptake in the soft
tissues was thought to be an area of myositis ossificans, subsequently
confirmed on ultrasound. The patient provided a history of trauma to the
area 1 year previously... |

Abnormal Bone Scan in an Adult With Osteopoikilosis
- Clinical Nuclear Medicine |
|
|
Osteopoikilosis is
rare, autosomal dominant bone disorder diagnosed by radiologic features.
The findings include multiple small, circumscribed round areas of
increased bone density distributed symmetrically in a periarticular
location. The lesions cluster at the ends of long bones, around the
acetabulum, and in the small bones of the hands and feet... |

Therapeutic ultrasound and fracture healing: A survey of beliefs
and practices -
Archives of Physical Medicine and Rehabilitation |
|
|
Conclusions: Some
surgeons and PT students believed that therapeutic ultrasound is
contraindicated and harmful to healing bone; however, most believed that
therapeutic ultrasound may help in assisting fracture healing, in at
least some cases. Current usage of this modality is rare, primarily due
to the perceived lack of evidence and lack of availability. Large
randomized trials are needed to define further the role of ultrasound in
fracture healing... |
