Rinne revisited: steel versus aluminum tuning forks.
OBJECTIVE (1) Determine whether tuning fork material (aluminum vs stainless steel) affects Rinne testing in the clinical assessment of conductive hearing loss (CHL). (2) Determine the relative acoustic and mechanical outputs of 512-Hz tuning forks made of aluminum and stainless steel. STUDY DESIGN Prospective, observational. SETTING Outpatient otology clinic. SUBJECTS AND METHODS Fifty su...
متن کاملTuning Forks and Tests
The three tuning forks generally used include : 256 Hz, 512 Hz, 1024 Hz. Most common being 512Hz. 512 because It has appropriate decay time, Less overtones and lies in speech frequency. Compressing the prongs with fingers produces around 70 dB sound and hitting against Knee or elbow 90dB. A prediction of air-bone gap can be made if tuning forks of 256, 512 and 1024 Hz are used. • Rinne test equ...
متن کاملComparing the accuracy of quantitative versus qualitative analyses of interim PET to prognosticate Hodgkin lymphoma: a systematic review protocol of diagnostic test accuracy
INTRODUCTION Hodgkin lymphoma is an effectively treated malignancy, yet 20% of patients relapse or are refractory to front-line treatments with potentially fatal outcomes. Early detection of poor treatment responders is crucial for appropriate application of tailored treatment strategies. Tumour metabolic imaging of Hodgkin lymphoma using visual (qualitative) 18-fluorodeoxyglucose positron emis...
متن کاملAcoustic Analysis of Used Tuning Forks.
OBJECTIVE In this study, we evaluated used aluminum tuning forks (TFs) for fundamental frequencies (FF), overtones, and decay times. MATERIALS AND METHODS In total, 15 used (1 C1, 11 C2, and 3 C3) and 1 unused (C2) TFs were tuned, and the recorded sound data were analyzed using the Praat sound analysis program. RESULTS It was found that FFs of the recorded sounds produced by the used C2-TFs...
متن کاملDiagnostic accuracy of stress perfusion CMR in comparison with quantitative coronary angiography: fully quantitative, semiquantitative, and qualitative assessment.
OBJECTIVES This study's primary objective was to determine the sensitivity, specificity, and accuracy of fully quantitative stress perfusion cardiac magnetic resonance (CMR) versus a reference standard of quantitative coronary angiography. We hypothesized that fully quantitative analysis of stress perfusion CMR would have high diagnostic accuracy for identifying significant coronary artery sten...
