Twinkling sign?
the patient's medical records and conditions, as a firm examination including a skin biopsy must be undertaken. Robert F. Reilly reported that they might have missed milder presentations of NSF, or the clinicians may have missed full-blown cases of NSF [7]. In the FINEST study [8], which the authors are also mentioning in their comments, we find it interesting that, among the 308 patients inclu...
متن کاملSonographic detection of renal and ureteral stones. Value of the twinkling sign.
PURPOSE To compare the detection of urinary stones using standard gray scale ultrasound for diagnostic accuracy using the color Doppler "twinkling sign". MATERIALS AND METHODS Our study population consisted of forty-one patients who demonstrated at least one urinary stone on unenhanced CT evaluation of the kidneys or ureters. Each patient was evaluated using gray scale ultrasound and color Do...
متن کاملThyroid B-flow twinkling sign: a new feature of papillary cancer
BACKGROUND Microcalcifications (aggregated with psammoma bodies), detected by ultrasound (US), are the most specific feature of papillary thyroid cancer (PTC). Using B-flow imaging (BFI), we identified a new sign (the twinkling sign; BFI-TS) in 'suspect' PTC nodules, which appeared to be generated by microcalcifications. OBJECTIVE To evaluate whether the BFI-TS was predictive of malignancy, w...
متن کاملPulsar twinkling and relativity
The number of pulsars with detected emission at X-ray and γ-ray energies has been steadily growing, showing that beams of high-energy particles are commonly accelerated in pulsar magnetospheres, even though the location and number of acceleration sites remain unsettled. Acceleration near the magnetic poles, close to the polar cap surface or to higher altitudes in the slot gap along the last ope...
متن کاملBifurcations in Twinkling Oscillators
We present the underlying dynamics of snap-through structures that exhibit twinkling. Twinkling occurs when the nonlinear structure is loaded slowly and the masses snap-through, converting the low frequency input to high frequency oscillations. We have studied a nonlinear spring-mass chain loaded by a quasistatic pull. The spring forces are assumed to be cubic with intervals of negative stiffne...
