Two-dimensional and shear wave elastography ultrasound: A reliable method to analyse spastic muscles?

abstract：INTRODUCTION:Twenty-six patients with clinical symptoms of adult onset carnitine palmitoyltransferase II (CPTII) deficiency were examined. All patients had skeletal muscle CPTII enzyme activity levels indicative of heterozygosity for CPT2 mutations, however sequence analysis identified no pathogenic mutations within th...
