Tendon Hyperechogenicity - Radiology Key
Apr 9, 2020 · • Areas of tendon hyperechogenicity are usually due to calcification or crystal deposition within tendon substance Alternatively gas, blood, or suture • US is more sensitive than radiography or MR at detecting calcification or crystal deposition within tendon
Sonography of Lower Limb Muscle Injury - AJR
Sonographically, the scar appears as a hyperechoic or heterogeneous, linear, or stellate lesion adherent to the epimysium (Fig. 12A, 12B, 12C, 12D). The lesion does not change with contraction of the muscle belly.
Hyperechoic - Radiology In Plain English
Sep 29, 2024 · Scar Tissue: Scar tissue formed after surgery or injury can reflect more ultrasound waves, making it appear hyperechoic compared to the surrounding normal tissue. 4. Fibrosis: Areas of fibrosis or fibrous tissue within organs can create hyperechoic regions on …
High resolution ultrasound for imaging complications of muscle injury …
Muscle healing after injury occurs within a period of weeks following a three-phase physiological process. Disruption of the normal healing process may lead to a number of complications, including excessive scar formation, myositis ossificans, muscle …
Diagnostic Ultrasound of the Hamstring Muscle Group
Acute hamstring injuries represent a spectrum of strains (grade 1) to full thickness tears (grade 3) all of which may be sonographically evident. More chronic or subacute injuries may involve proximal or distal tendinopathies, pes anserine bursitis or ischial bursitis.
High Hamstring Tendinopathy: MRI and Ultrasound Imaging and …
MRI is more sensitive than ultrasound in detecting peritendinous edema and tendinopathy at the proximal hamstring origin. Fifty percent of patients had symptomatic improvement lasting longer than 1 month after percutaneous corticosteroid injection, and 24% of patients had symptom relief for more than 6 months.
Hamstring injury - The Radiology Assistant
Nov 14, 2022 · Old injury. After the injury, it is possible that the tendon looks normal after healing. However, in most partial injuries, fibrous scarring is seen at the site of the previous injury (yellow dotted circle). Quite often, when MRI is made for an acute injury, other sites of fibrous scarring of older injuries are seen.
Sonographic landmarks in hamstring muscles - PMC - PubMed …
Therefore, it is important to know the specific ultrasound reference points that facilitate the location of the hamstring structures, dividing them into four areas of interest: (a) tendinous origin of the hamstring, (b) the proximal half, (c) distal and medial half, and (d) distal and lateral half.
