Novel tissue harmonic imaging clearly visualizes a case of intraductal papillary mucinous neoplasm with mural nodules.
Tissue Harmonic Echo (THE) imaging is a sonographic technique that potentially provides images of higher quality than can conventional B-mode images. Potential advantages of THE imaging include improved resolution, improved signal-to-noise ratio, and reduced artifacts [1, 2]. Recently, a novel THE imaging performed using an EUS system with a monitor/processing unit (EU-ME2 PREMIER PLUS; Olympus...
متن کاملComparing differential tissue harmonic imaging with tissue harmonic and fundamental gray scale imaging of the liver.
OBJECTIVE The purpose of this study was to compare fundamental gray scale sonography, tissue harmonic imaging (THI), and differential tissue harmonic imaging (DTHI) for depicting normal and abnormal livers. METHODS The in vitro lateral resolution of DTHI, THI, and sonography was assessed in a phantom. Sagittal and transverse images of right and left hepatic lobes of 5 volunteers and 20 patien...
متن کاملTissue harmonic imaging
Harmonics have much significance in music. A musical note has three characteristics. 1 Pitch (or frequency) 2 Loudness 3 Quality (or tone). Quality is the audible difference heard between two musical notes of the same pitch and loudness. Hence, a piano based C-note does not sound the same as a C-note played on a guitar, due to the existence of harmonic frequencies. The same note from various in...
متن کاملInvestigation of the effect of subcutaneous fat on image quality performance of 2D conventional imaging and tissue harmonic imaging.
Tissue harmonic imaging (THI) has been reported to improve contrast resolution, tissue differentiation and overall image quality in clinical examinations. However, a study carried out previously by the authors (Brown et al. 2004) found improvements only in spatial resolution and not in contrast resolution or anechoic target detection. This result may have been due to the homogeneity of the phan...

death to give reliable results. The postmortem interval as already defined established fixed limits for the interval and avoided possible overestimation of the amino acid concentration relative to time after death. Analysis of the results showed no evidence that a specific aminoacidopathy is implicated in the aetiology of cot death but has nevertheless improved our understanding of the biochemi...
