Magnetic resonance neurography (MRN) is the direct imaging of nerves in the body by optimizing selectivity for unique MRI water properties of nerves. It is a modification of magnetic resonance imaging. This technique yields a detailed image of a nerve from the resonance signal that arises from in the nerve itself rather than from surrounding ...
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to form images of the organs in the body.
A skeletal survey (also called a bone survey [1]) is a series of X-rays of all the bones in the body, or at least the axial skeleton and the large cortical bones. A very common use is the diagnosis of multiple myeloma, where tumour deposits appear as "punched-out" lesions.
Contusions of both surfaces of the knee joint are known as kissing contusions. These contusions are generally found by magnetic resonance imaging and most cases are associated with ligamentous or meniscal injuries. [1]
An x-ray may be performed in addition to evaluate whether one of the bones in the knee joint was broken during the injury. [9] MRI is perhaps the most used technique for diagnosing the state of the ACL, but it is not always the most reliable technique as the ACL can be obscured by blood that fills the joint after an injury. [34] MRI is ...
The needle is radiographically guided into the glenohumeral joint space, after which the patient is evaluated by fluoroscopy, CT or MRI. The gadolinium in the contrast fluid yields a bright signal on T1 weighted images allowing for better evaluation of the joint capsule , the articular surface of the bones and, in particular, the labral cartilage.
A knee dislocation is an injury in which there is disruption of the knee joint between the tibia and the femur. [3] [4] Symptoms include pain and instability of the knee. [2] Complications may include injury to an artery, most commonly the popliteal artery behind the knee, or compartment syndrome. [3] [4] [7]
The foot is externally rotated 10-15° and the examiner supplies an anterior and external rotational force. The joint can then be evaluated for tibial anteromedial rotation, taking care to recognize the possibility of posterolateral corner instability giving similar rotational test results. As always, compare the test in the opposite knee. [4 ...
