The aim of this study is to propose a new measurement point for temporal muscle thickness (TMT) that can be similarly localized in computerized tomography (CT) /magnetic resonance imaging (MRI) and ultrasonography (USG), and to evaluate the reliability and consistency of these measurements.
Recently, temporal muscle thickness (TMT) has been proposed as a new marker of whole-body muscle function. In addition, TMT has been shown to be a useful parameter for estimating skeletal muscle mass. Measurement of temporal muscle mass with CT and MRI has been studied in the literature in recent years. All stroke patients undergo cranial CT or MRI examinations at the time of admission. However, the literature indicates that USG can also be used to measure temporal muscle thickness. The recommended measurement points for CT, MRI, or USG in the studies performed to date depend on the particular imaging modality, and it does not seem possible to use them interchangeably. The aim of this study is to propose a new TMT measurement point that can be localized in a similar way in CT /MRI and USG, and to evaluate the reliability and agreement of these measurements.

Intra-rater reliability of ultrasonographic TMT measurement.
The intraclass correlation coefficient (ICC) of the two measurements performed by the physiatrist will be calculated using the "Two-way mixed effects, absolute agreement, single rater/measurement" model.
Time frame: Baseline
Inter-rater reliability of ultrasonographic TMT measurement.
Intraclass correlation coefficients of TMT measurements performed by the radiologist and physiatrist will be calculated using the "Two-way mixed effects, absolute agreement, multiple raters/measurements " model.
Time frame: Baseline
Inter-rater reliability of TMT measurements of MRI and CT
Intraclass correlation coefficients of TMT measurements performed by the radiologist and physiatrist will be calculated using the "Two-way mixed effects, absolute agreement, single rater/measurement " model.
Time frame: Baseline
Agreement of ultrasonographic TMT measurement with MRI and CT measurements.
The intraclass correlation coefficient of the measurements will be calculated using the "two-way mixed effects, absolute agreement, multiple raters/measurements" model. In addition, the agreement of the measurements will be evaluated using the Bland-Altman method. Furthermore, the Technical Error of Measurement (TEM) will be calculated.
