The predictive value of CT-based skeletal muscle attenuation measurements for sarcopenia according to age and sex

Abstract

Aim: We aimed to compare the skeletal muscle attenuation measurement values in CT scanning, which is widely used in clinical practice, with literature and to contribute to the diagnosis of sarcopenia without additional examination and radiation dose. Materials and Methods: Patients with spinal and lumbar CT images in the PACS archive of Ege University Department of Radiology were retrospectively reviewed. The study included 200 patients who underwent spinal or lumbar CT examinations without contrast between 2020 and 2024. The skeletal muscle densities of these patients were measured manually by a musculoskeletal radiologist using the ROI (Region of Interest) area and circle method. Results: There is a statistically significant difference between area and circle measurements for each muscle group in all age groups. The measurements made with the ROI circle were higher compared to the area values (p<0.001). All ROI measurements showed a significant difference when compared according to age in female and male groups (p<0.001). In female patients over 60 years of age, mean ROI area values were 28.6±9.7 right psoas, 28.9±8.2 left psoas, 5.9±16.9 right paraspinal, 6.5±18.0 left paraspinal; in male patients over 60 years of age, 14.9±17.9 right paraspinal, 14.8±18.2 left paraspinal. Conclusion: Muscle density data obtained by computed tomography is an important component in the diagnosis of sarcopenia and should be integrated into clinical practice. CT provides important information to the clinician in terms of prevention and treatment of muscle loss, especially in elderly individuals.

Öz

Amaç: Klinik pratiğinde yaygın olarak kullanılan BT çekiminde iskelet kas atenüasyon değerlerinin literatür ile birlikte karşılaştırılması, ek tetkik ve radyasyon dozuna maruz kalmadan sarkopeni tanısına katkısının değerlendirilmesi amaçlanmıştır. Gereç ve Yöntem: Ege Üniversitesi Radyoloji Anabilim Dalı PACS arşivindeki spinal ve lomber BT görüntüleri bulunan hastalar retrospektif olarak taranmıştır. Çalışmaya, 2020-2024 yılları arasında kontrastsız olarak spinal ya da lomber BT incelemesi yapılmış 200 hasta dahil edilmiştir. Bu hastaların iskelet kas dansiteleri kas iskelet radyoloğu tarafından ROI (region of interest) alan ve ROI çember yöntemi ile manuel olarak ölçülmüştür. Bulgular: Tüm yaş gruplarında her kas grubu için alan ile çember ölçümleri arasında istatistiksel anlamlı farklılık saptanmıştır. ROI çember ile yapılan ölçümler alan değerleri ile kıyaslandığında daha yüksek bulunmuştur (p<0,001). Tüm ROI ölçümleri kadın ve erkek gruplarında yaşa göre karşılaştırıldığında anlamlı farklılık gösterdi (p<0,001). 60 yaş üzeri kadın hasta grubumuzda ortalama ROI alan değerleri sağ psoas 28,6±9,7, sol psoas 28,9±8,2, sağ paraspinal 5,9±16,9, sol paraspinal 6,5±18,0, 60 yaş üzeri erkek grupta ise sağ paraspinal 14,9±17,9, sol paraspinal 14,8±18,2 ölçüldü. Sonuç: Bilgisayarlı tomografi ile elde edilen kas atenüasyon verileri, sarkopeni tanısında önemli bir bileşen haline gelirken, klinik pratiğe entegre edilmesi gereken bir yaklaşımdır. Özellikle yaşlı bireylerde kas kaybının önlenmesi ve tedavi edilmesi açısından klinisyene önemli bilgiler sağlamaktadır.
