Temperature change in lumbar periarticular tissue with continuous ultrasound.
STUDY DESIGN Counterbalanced, within-subjects experimental design. OBJECTIVE To determine the effect of continuous 1-MHz ultrasound, given at 1.5 W/cm2 and 2.0 W/cm2 for 10 minutes, on tissue temperature in the region of the L4-L5 zygapophyseal joint. BACKGROUND Ultrasound is a modality commonly used for the treatment of lower back pain syndromes. Randomized controlled trials supporting the...
متن کاملRelative brightness due to temperature changes with ultrasound image analysis during Radiofrequency ablation
Introduction: Diagnosis of primary and secondary cancers to treat patients with diffuse and malignant tumors is an important subject. The appropriate treatment will be eliminating primary and metastatic tumors. Radiofrequency ablation with localized heat induction in the target tissue causes irreversible cellular damage and tissue coagulation. Estimation of tissue temperature c...
متن کاملChanges in self-assemblies induced by temperature, concentration and light.
In this review, changes in aggregation induced by thermodynamic parameters, namely concentration and temperature are discussed. Most of these changes are concerned with sphere-to-rod transitions. On the other hand, the use of an external trigger such as light can induce large aggregation changes in photosurfactant systems. This is discussed in the second part of this review and several examples...
متن کاملCholera toxin effects on body temperature changes induced by morphine.
The present study evaluates the influence of cholera toxin and its B-subunit on thermic responses to morphine in the rats. The holotoxin (1 microg/rat) and the B-subunit (5 microg) were administered ICV and three days later rats were challenged ICV with morphine and tested for changes of body temperature. Cholera toxin, but not its B-subunit, modified the time course of the hyperthermic respons...
متن کاملTemperature changes caused by the difference in the distance between the ultrasound transducer and bone during 1 mhz and 3 mhz continuous ultrasound: a phantom study
[Purpose] This study aimed to use a thermograph to observe temperature changes caused by different distances between an ultrasound transducer and bone during 1 MHz and 3 MHz continuous ultrasound emission on a phantom. [Materials and Methods] We observed the distribution of temperature elevations on a phantom consisting of pig ribs and tissue-mimicking material. One megahertz and 3 MHz ultrasou...
