title: [CT and magnetic resonance imaging and spectroscopy for non-invasive study of regeneration of skeletal musculature after intensive therapy].
abstract: A 50 year old man was treated in the intensive care unit. Due to a prolonged catabolic state with a loss of 35 kg of body weight, he was practically paralyzed following 70 days of treatment. After 200 days of intensive physical training, he had recuperated remarkably. CT-scans before and after the physical training revealed 90-180% increase in the muscles examined. At the femoral level the muscle/fat ratio increased from 40% to 70%, indicating less atrophy. MR-imaging of the crural muscles showed a substantial increase in the muscle mass after training. MR-fat/water proton spectra showed a decrease in the relative fat content from 0.31 to 0.13 during training, objectively measuring the remission of the severe atrophy.
  
  
  CONCLUSIONS
  CT- and MR-techniques can be used for objective, non-invasive, evaluations of muscle condition, and MR-proton spektroscopy can probably be used for following the remission of muscle atrophy during physical training.
