Muscle groups that have been previously used to validate and correlate US with MRI include the quadriceps muscles [18, 19], rotator cuff muscles [13], hamstring muscles [20], biceps and triceps brachii muscles [21], and core trunk muscles [8, 22]. The fibrous tunnels of the flexor hallucis longus and of the long flexor of the fifth toe are demonstrated.

The spleen is located lateral to the left kidney, while the duodenum, jejunum and descending colon are found anteriorly to the kidney and spleen. Reeves ND, Narici MV, Maganaris CN (2004) Effect of resistance training on skeletal muscle-specific force in elderly humans. © 2005–2023 Elsevier. Located deeper and encircling the entire cavity is the muscular diaphragm. L5||Convergence of right and left common iliac veins (Inferior vena cava)|. Located posteriorly and from medial to lateral, they are named: longissimus thoracis, iliocostalis lumborum, and latissimus dorsi. The central intermediary compartment is triangular, lodging the flexor digitorum longus. The superficial dorsal aponeurosis extends vertical fibers to the skin and closes the dorsal subcutaneous space along its margins. The figure shows the distal surface of a coronal section through the distal segment of the metatarsals 2-3-4 and the heads of metatarsals 1 and 5.
Ethics approval and consent to participate. Assessment of quadriceps muscle cross-sectional area by ultrasound extended-field-of-view imaging.
