Menisci are cartilaginous cushion like structures encountered in the knee joints. These are two in number and located in the medial and lateral compartments of the knee joint, one each in one compartment. Meniscus is notorious for sustaining injuries in sport-related injuries, but the clinical diagnosis of a meniscal injury in the form of a tear is very difficult…

Therefore, prior diagnosis of the location, disposition, depth, orientation, and extent of the meniscal tear becomes of utmost importance, since this would facilitate the optimum treatment and outcomes within the shortest possible time.
This specific dilemma has two parts, one questionable accuracy magnetic resonance imaging studies and failure of appropriate interpretation of the images to lead to a definitive diagnosis unequivocally (Luhmann, Schootman, Gordon, & Wright, 2005). On the other hand, delay for allowance of development of suggestive clinical signs or symptoms may lead to permanent damage. Before going into the details of these issues, it would thus be necessary to establish the facts that are known in each of these issues with an attempt to find relevance between these two, so the evidence base may be available for guiding practice. This issue has been dealt with in adequate detail in prior researches, and thus there is a need for extended literature review to glean what is known. Apart from establishing evidence from the known, it would also serve the purpose of identification of the gaps, so further research may be conducted on these suggestions.
Rationale of the Literature Review
Mesiha et al. (2006) indicated the tricky nature of human meniscal healing following injury. It has been observed that meniscus often fails to heal when the injury has caused a tear of more than 1 cm. similar phenomena have been observed when the tear involves the internal two-thirds of the meniscus (Mesiha, Zurakowski, Soriano, Nielson, Zarins, & Murray, 2006). Menetrey and colleagues (2002) reported failure of healing of peripheral meniscal tears. The failure of recognition of meniscal tears is so rife that, some authors suggested very high meniscal repair failure rates (Menetrey, Siegrist, & Fritschy, 2002). As Venkatachalam et al. (2001) indicated the healing failure may be very high since many patients remain asymptomatic even with an existing tear of the meniscus (Venkatachalam, Godsiff, & Harding, 2001) .
It can be deduced from these studies that although magnetic resonance imaging is available as a diagnostic imaging modality for meniscal injuries, it is questionable whether routine magnetic resonance imaging would be advisable for all suspected cases of meniscal injury or whether in all such cases even after the imaging is done, it would be rational for a radiologist to interpret the image in order to arrive at a diagnosis.
Research Question
This leads to the research question for this study which is whether routine magnetic resonance imaging for all suspected cases of meniscal tears is optimal, appropriate, or necessary diagnostic modality

...? MRI Institute MRI Answer no Elbow is the joint of the upper limb. It is located between the distal end of humerus and the proximal end of forearm. It connects the humerus with the two forearm bones, Radius and Ulna. The connection these bones form is known as the elbow joint. It is a complex type of joint of hinge- pivot variety. A number of bony surfaces are involved in the formation of the elbow joint. The distal end of humerus has two condyles, one on its medial side and another on the lateral side. These condyles, along with their epicondyles provide the site for the attachment of the ligaments and tendons. Apart from these condyles, which are bony prominences, the distal end of humerus has two depressions as well. The bony... . The...

Many of these injuries are caused by activities in day-to-day living and this injuries result in the reduction of the work force. In human body, there is a fluid called bursa sac, which exists between the joints of the body, in order to smooth out movements and minimize the friction. Inflammation of this liquid result in one of the most common repetitive motion injuries called Bursitis (Vigorita et al., 2007). Bursa is never inflamed on its own but when it is used for a long period, or there is an injury on a joint that exerts a pressure... on it, then...

Traumatic Injuries

...? Traumatic Injuries Question 1a: How you would prevent traumatic injuries from slips and falls at the company. Firstly, risk assessments of tasks and associated workplace should be conducted so that safe work policies and procedures can be developed. Risk assessments identify potential safety problems for each task performed. Slips and falls are common when there are liquid chemicals involved in the production (Workplace Safe, 2008). In case of microchip plants, chemicals used in the processing go through conduits (Intel, 2008). Spillage may thus occur if there are defective tubes that can lead to fluid leaks. This can be prevented by doing a regular check-up on these lines. In addition, Aside from these...

...) and diagnosis of soft tissue problems such as brain tumours, multiple sclerosis, torn ligaments, shoulder injuries and earlier stages of stroke. MRI offers multiple privileges to probe deep into soft tissues which CT scans or X-ray do not provide. Secondly, they don’t use any ionising radiations and are thus claimed safe as radio waves are found all around and do not damage the tissues. (Berger, 2002) Thirdly, MRI offers diagnosis of a specific area in the patient at various planes unlike CT scan that is limited only to one plane. (WebMD, 2009) However, there are several limitations to it such as 1) high cost of an MRI scan; 2) victims of claustrophobia are hesitant to...

...of a knee sample and will present some of the MRI images obtained with several mechanisms of the system inside the field of the MRI. Injury in knee Knee injury can occur by a twisting or turning that is quick and sudden, and most likely when the foot is planted while the knee is bent; tearing the meniscus. A meniscus tear can also occur when lifting a heavy object from a low surface or when playing sports. As we get older, the meniscus gets worn out, so one has a higher risk of having a meniscus tear. A meniscus is a rubbery, c- shaped disc that cushions the knee. Each knee has 2...

...MRI MRI, i.e. Magnetic Resonance Imaging is a tried and tested technique to record the activities of brain. MRI is used to diagnose brain tumours using the functional magnetic resonance imaging (fMRI) scans (Reese, 2005). There are other imaging techniques like Ultrasound, computer-assisted tomography (CT), and X-ray, but MRI is considered the most reliable of them all. MRI is mainly used to diagnose tumours in softer tissues in human body parts. This type of imaging produces a variety of images. These images help in configuring the human body in distinctive manner which in turn helps in detecting pathology. The spatially variable data within the human...

Meniscus of the Knee

...during participation in recreational activities such as skiing, dancing, or racquetball. There are two different mechanisms for tearing a meniscus. Traumatic tears result from a sudden load being applied to the meniscal tissue which is severe enough to cause the meniscal cartilage to fail and let go. These usually occur from a twisting injury or a blow to the side of the knee that causes the meniscus to be levered against and compressed. Degenerative meniscal tears are best thought of as a failure of the meniscus over time. There is a natural drying-out of the inner centre of the meniscus that can begin in the late 20's and progresses with age. The...

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...

Sports injuries

... Sports Injuries Sports injuries occur during play or exercises. They can be caused by poor training, accidents and improper protective gear. In some cases, they can arise from secondary health effects, particularly chronic conditions. Lack of warm-up exercises before playing can also cause injuries. Concussion Concussion refers to a minor form of traumatic brain injury that is caused by blows, pumps, or jolts to the head. It can also be caused by heavy blows on the body that can make the head shake rapidly. It triggers an immediate loss of consciousness that is accompanied by amnesia. Although most people do not lose their consciousness, there is a tendency to forget events prior to or immediately after concussions. In some cases... ...
