Description of intervention(s) / exposure
The participants will be asked to wear or bring shorts and a t shirt and will be expected to be in the clinical research area for 2 hours in total, on one occasion. Participants will be landmarked at the right mid-bicep, right and left mid-thigh and 2/3 thigh. Researchers will use the Phillips Lumify Ultrasound portable ultrasound machine with the B-mode L12-4 linear array transducer. The MRI and US measurements will be taken on the same occasion. Trained staff at the Centre for Advanced MRI will conduct the take the MRI measurements. Three images will be taken at each site. The US images will be taken by research dietitians who have undergone training. There is only one ultrasound method.

Diagnosis / Prognosis
Comparator / control treatment
The participants will be required to be on site for a total of two hours on one occasion. MRI scans will be performed using a 3T Vida-Fit scanner (MAGNETOM, Siemens Healthineers; Erlangen, Germany) with a dedicated body coil. The participants will lie in a supine position with the right arm and both thighs in a neutral position. The landmarked positions and image processing will mimic the ultrasound protocol. Landmarks will be marked by placing a vitamin E capsule at the scan site. Trained staff at the Centre for Advanced MRI will conduct the take the MRI measurements. Three images will be taken at each site.

Outcomes
Primary outcome [1] 335311 0
The primary outcome is the average muscle thickness across the following sites as a composite score. Participants will be landmarked at the right mid-bicep, right and left mid-thigh and 2/3 thigh. Philips Lumify (Philips Ultrasound, Bothall, WA) handheld portable B-mode L12-4 linear array transducer will be used to measure thickness of the bicep brachii of the arm and the rectus femoris of both legs at two points (1/2 way and 2/3 point).

Participants will be landmarked at the right mid-bicep, right and left mid-thigh and 2/3 thigh as a composite score. Philips Lumify (Philips Ultrasound, Bothall, WA) handheld portable B-mode L12-4 linear array transducer will be used to measure cross sectional of the rectus femoris of both legs at the 2/3 point.
