The flexor retinaculum separates the carpal tunnel from the ulnar canal, which transports the ulnar nerve and artery. If the density is altered, we express that by using basic CT terminology; hyperdense, hypodense or isodense when compared to some other structure. If misdiagnosed it can limit athletes performances and lead to surgery. The most effective form of muscle training in cases of tendon problems is eccentric training because the collagen fibers will be set in the right/functional direction. 3, Sartorius muscle. The quadratus femoris is a flat, quadrilateral skeletal muscle.Located on the posterior side of the hip joint, it is a strong external rotator and adductor of the thigh, but also acts to stabilize the femoral head in the acetabulum.Quadratus femoris use in the Meyer's muscle pedicle grafting to prevent avascular necrosis of femur head.

Next, take a look at the outer surface of the brain, this thin white layer is the cortical gyri. [4] Common causes are either a direct varus force, while the tibia is externally rotated, or a sudden forced knee hyperextension with the tibia internally rotated[1][5][6] It may also be associated with hyperpronation of the foot because this causes an external rotation of the tibia[7]. 1, Patellar tendon.

Static stabilizers of the shoulder joint are the fibrous capsule, glenoid labrum and ligaments. The joint surfaces are lined with hyaline cartilage and are enclosed within a single joint cavity. This is often seen in car accidents, where the knee hits the dashboard. Cardiac refers to the heart silhouette, of which we see left and right margins. 1995;195(3):849-53. [12] Popliteus tendinopathy is often diagnosed in professional runners and triathletes. These take the same form as their palmar counterparts; dark black circles for the tendons and gray circles for the blood vessels. These are the carpal bones. MRI scanning takes longer than CT, and it can be uncomfortable for some people as the machine is very loud and requires the person to be placed in a narrow tube (problematic for people with claustrophobia). 6, Tibia. 8, Posterior cruciate ligament. PET can be used for functional examination of basically every body system - skeletal, cardiovascular, nervous, endocrine. 8, Lateral meniscus.

A lateral force to an extended knee, such as a rugby tackle, can rupture the medial collateral ligament, damaging the medial meniscus in the process. 3, Femur. The right margin features the two convexities; the lower comes from the right atrium, and the upper comes from the ascending aorta. (2007) ISBN: 0323043615 -. As the patella is both formed and resides within the quadriceps femoris tendon, it provides a fulcrum to increase power of the knee extensor and serves as a stabilising structure that reduces frictional forces placed on femoral condyles. This webpage presents the anatomical structures found on thigh MRI. The basic MRI methods are: MRI is mostly used for neuroimaging (NMRI), musculoskeletal, gastrointestinal and cardiovascular system assessments. ADVERTISEMENT: Supporters see fewer/no ads. Our scan shows the frontal sinus, ethmoidal cells and mastoid cells. Chest CT is another thorax imaging modality with particular usefulness for showing the lung interstitium, as well as the sizes and diameters of organs and vessels.

The blood supply to the knee joint is through thegenicular anastomosesaround the knee, which are supplied by the genicular branches of the femoral and popliteal arteries. These sounds echo from the contours of the inner body structures bouncing back to the transducer, which then translates them into a pixelated image displayed on the connected monitor. Friction between the skin and the patella cause the prepatellar bursa to become inflamed, producing a swelling on the anterior side of the knee. Image 4.

These waves pass through the persons body, with some rays being absorbed by the tissues and others reaching the radiographic film behind. Other tissues are somewhere in between of this grayscale. It is formed by articulations between the patella, femur and tibia. Nuclear medicine (PET) uses radionuclides or radiopharmaceuticals that emit radiation towards the imaging machine. 5, Medial head gastrocnemius muscle. If the medial collateral ligament is damaged, it is more than likely that the medial meniscus is torn, due to their attachment. 7, Medial meniscus.
