Extract of sample "Fundamental Musculoskeletal MRI"

Download file to see previous pages The anterior elbow, on the other hand, has two fossae: medial coronoid fossa and lateral radial fossa. However, similar to the posterior elbow, only one capsular attachment covers these two fossae. The proximal end of the ulna has two processes, the olecranon and coronoid, with the former being the site of attachment of the triceps tendon. Aside from the head, the radius also has a tuberosity, located beneath the medial aspect of the neck (Bhutani, 2011).
The structure of the elbow is maintained by a weak fibrous tissue that envelopes the whole joint. The synovial membrane lines the inner surface of the capsule, and in between the synovial membrane and capsule are several fat pads. The collateral ligament complexes on the elbow are found to overlie the capsule. The radial or a lateral collateral ligamentous complex consisting of the radial ligament, annular ligament, lateral ulnar collateral ligament, and accessory ligament attaches superiorly to the lateral epicondyle and inferiorly to the radial notch of the ulna and the annular ligament. On the other hand, the ulnar or medial collateral ligament spans from the medial epicondyle to the coronoid and olecranon processes. At the elbow is another joint, called the radioulnar joint, which is between the radial head and the radial notch of the ulna (Bhutani, 2011).
In conducting elbow MRI, the patient can be positioned prone or supine, with the arm overhead. Taking the latter is more comfortable for the patient (Vahlensieck, Genant, Reiser, 2000). Imaging is from 10 cm above the elbow joint to the bicipital tuberosity (Bhutani, 2011). The elbow MRI imaging options are axial, sagittal, coronal, oblique, and reformatted thin-section gradient-echo images. The axial image is necessary to assess neurovascular, tendon, and muscle anatomy. The sagittal view is also taken for biceps and triceps tears or to define the extent of a lesion seen on axial MRIA. ...Download file to see next pages Read More

Apart from these condyles, which are bony prominences, the distal end of humerus has two depressions as well. The bony depression on the anterior side is known as coronoid fossa, while the posterior depression is known as olecranon fossa. The areas where the bones connect to each other are referred to as articular surfaces. The elbow joint is articulated at Radioulner, Radiohumeral and Ulnohumeral joints. These articular surfaces are covered by the hyaline cartilage. A joint capsule, which is lined by Synovial membrane, encloses the entire joint in such a way that all three joint cavities remain in communication with each other. The elbow joint is stabilized by ligaments. These include Radial and Ulnar Collateral ligaments and th...

Musculoskeletal Disorders

... Musculoskeletal Disorders Musculoskeletal disorders (MSDs) denote various forms of disorders, injuries or damages that occur to tissues or joints in the back or lower and upper limbs. The commonly affected tissues include tendons, muscles, cartilage, spinal discs, nerves and joints. Commonly affected parts of the human anatomy include the upper and lower limbs as well as the neck, back and shoulders. MSDs are commonly caused by incidences that lead to overworking of the tissues involved. Overworking in this case implies engagement of muscles or supportive tissues in bearing loads and forces that they are originally not designed to bear (CDC, 2012). Musculoskeletal disorders may be caused by multiple factors, but most of them are work...

Musculoskeletal MRI

...? MUSCULOSKELETAL MRI By Presented to [Your Femoroacetabular Impingement (FAI) Femoroacetabular Impingement (FAI) is the condition during which there is a lot of friction at the hip joint. In more explicit terms, the femoral head (ball) and the acetabulum (socket) rub against one another in an abnormal manner, which leads to the damage of the hip joint (HipFAI 2013). The damage from the friction is caused on the articular cartilage, which is the smooth, white coloured surface of the socket or the ball; the adjacent labral cartilage. The labral cartilage is the soft tissue-matter bumper, which is located at the socket (HipFAI 2013). FAI occurs in two forms that include pincer and cam. The cam form derives from the relationship between...

...?Introduction The acronym MRI stands for Magnetic Resonance Imaging is one of the best knows methods of medical imaging and tissue characterization. This theory was proposed by two eminent scholars of science, Raymond Damadian and Paul Lauterbur, who had been working independently and proposed this new concept roughly in late 1960s. This technique is basically nuclear magnetic resonance imaging, which involves computation of resonance signals obtained when an atomic nucleus is exposed to static magnetic field. MRI makes use of the natural magnetic proprieties of atoms within the body. Due to huge abundance of water in the body, hydrogen atoms are focused upon in this process. Upon applying the magnetic field, the hydrogen atoms align...

Musculoskeletal System

...A Journal Review of the Musculoskeletal System: Understanding common disorders and their management Introduction 'Assessing and Managing Patients with Musculoskeletal Conditions' is a journal article in the September 2007 issue of Nursing Standard. Its author Nicola Judge is a lecturer in adult nursing in the St. Bartholomew School of Nursing and Midwifery. The article discusses the anatomy and physiology of the musculoskeletal system and the management of conditions that affect this system. The article is also able to give brief discussions on the common conditions that affect this system and common management techniques that can help alleviate pain associated with these conditions. Summary The musculoskeletal system is responsible...

Slice thickness, is one important parameter, which divides the body part being examined into sections of varying width or thickness. The result of examination depends on the slice thickness. If it happens to be a minute problem, then the slice thickness will be small, because a larger slice thickness might result in erasing small lesions or pathologies.
MRI is mainly used to look into the brain and the nervous system of human body to figure out the inconsistencies using the functional magnetic resonance imaging, as these parts happen to be the most delicate parts of human body. Prasad (2005, 292) states that the 'MR images are in effect computer generated visual reconfigurations of physical data such as the relaxation times o...

...MAGNETIC RESONANCE IMAGING by of the school/ of the Describe how MRI sequences spatially en nuclei in the read and phase direction. Spatial encoding in read direction Readout or frequency encoding is achieved by encoding the signals along a direction in space with varying frequencies. Here, the spin echo signal is sampled n number of times where n is the number of projections along the frequency-encoded axis. To rebuild the distribution of the sources along the encoded direction, it is generally essential to obtain a set of signals with a suitable set of frequencies. When there are no other position encoding components present, the FT of the signal that results is simply a one-dimensional projection profile of the subject. A readout...

...MRI Brochure A to parents and carers It is suggested that parents and children study the brochure before coming for an MRI scan. Reading the brochure makes the children prepared for the examination and thus they accept the examination requirements. Children remain calmer during the examination and behave accordingly if they bring their favourite toys, pillows or blankets with them. If a child listen some favourite music, parents are advised to bring CDs or Players with them as it provides comfort during examination. In case of any apprehensions about the procedure, it is advised to discuss it with the Radiographer a technologist trained in medical imaging) or Radiologist (a doctor who specialises in medical imaging). What is the MRI...

...Musculoskeletal due: I agree with Peng Anderson about prioritizing the assessment of the patient on physical symptoms, lack of medical cover and preventive health care, stress and depression, sleep difficulties as well as drug use, BMI/waist circumference and lifestyle and family history of heart diseases, cholesterol level and cancer. The last four factors are closely interrelated in causing pain in the mid lumbar area. Lumbar disc complications such as degenerated discs can cause pain in the disc space. The pain eventually spreads to other lower parts such as buttocks, legs and feet (Buttaro, Trybulski, Polgar-Bailey, & Sandberg-Cook, 2012). Factors such as doing heavy physical work may cause degeneration of discs. Obesity, which can...
