Introduction: To investigate the effects of breathing cycle and tree diaphragm motions on prostate cancer tumors standard uptake value (SUV) during positron emission tomography (PET) and to correct it. Materials and methods: Respiratory motion traces were simulated on the common patient breathing cycle and tree diaphragm motio...

BACKGROUND Interfraction prostate motion must be compensated by increased safety margins. If filling status of rectum and bladder is constant, motion should be reduced. We attempted to reduce interfraction motion errors by proper patient instruction. METHOD In 38 patients pairs of radio-opaque fiducial markers were implanted prior to definitive radiotherapy. Patients were positioned either ac...

INTRODUCTION A prominent neurophysiological model of phobia generation holds that specific phobia might result from the uncoupling of unaware subcortical fear responses from aware cortical fear responses. Former responses are thought to be automatic and fast, providing approximate information about the external stimulus, whereas the latter responses are more controlled and allow comparison with...

We present a 23-year-old man with distal humerus osteoid osteoma referring to our hospital with pain and progressive stiffness. The patient has been suffering from the disease for two years without a certain diagnosis. The radiographies of elbow did not reveal the pathology but further CT scan and MRI studies demonstrated the tumor. The en block resection of the tumor resolved the pain immediat...

background abnormalities in the velocity and pattern of myocardial shortening on tissue doppler imaging (tdi) have been proposed to aid in the noninvasive diagnosis of coronary artery disease (cad). objectives we investigated the diagnostic value of post-systolic shortening (pss), a delayed ejection velocity of the myocardium after the closure of the aortic valve, on tdi in the diagnosis of cad...

   Tendon transfers in hand patients are a commonly performed procedure after extensor tendon rupture. However, the standard side to side technique is not applicable in every patient. We present a case of a musician with unique demands to demonstrate the option to customize surgical technique and therapy regimen to the unique needs of each patient. An extensor indicis proprius to extensor digit...

This case report details a clinical trial's first recruited liver cancer patient who underwent a course of stereotactic body radiation therapy treatment utilising audiovisual biofeedback breathing guidance. Breathing motion results for both abdominal wall motion and tumour motion are included. Patient 1 demonstrated improved breathing motion regularity with audiovisual biofeedback. A training e...
