We demonstrate that single photons from a rotating q-plate exhibit an entanglement in three degrees of freedom of spin, orbital angular momentum, and the rotational Doppler shift (RDS) due to the nonconservation of total spin and orbital angular momenta. We find that the rotational Doppler shift deltaomega = Omega((delta)s + deltal) , where s, l and Omega are quantum numbers of spin, orbital an...

AIM To monitor joint inflammation and destruction in rheumatoid arthritis (RA) patients receiving adalimumab/methotrexate combination therapy using MRI and ultrasonography. To assess the predictive value of MRI and ultrasonography for erosive progression on CT and compare MRI/ultrasonography/radiography for erosion detection/monitoring. METHODS Fifty-two erosive biological-naive RA patients w...

ndometrial vasculature has been shown to play an important role in the early endometrial response to the implanting blastocyst, and vascular changes may contribute to uterine receptivity . the aim of this study was to investigate the role of endometrial and subendometrial vascularity and thickness in uterine receptivity in infertile women treated with assisted reproductive technologies (art). a...

OBJECTIVE To determine the value of gray-scale and power Doppler ultrasonography in the evaluation of carpal tunnel syndrome (CTS). MATERIALS AND METHODS Median nerves at the carpal tunnel were evaluated by using gray-scale and power Doppler ultrasonography and by using accepted and new criteria in 42 patients with CTS (62 wrists) confirmed by electromyogram and 33 control subjects. We evalua...

Doppler backscattering systems (DBSs) have been widely used in magnetic confinement fusion devices to measure the density fluctuations and propagation velocity of turbulence. However, the received signals of a DBS usually include both zero-order reflection and backscattering components, which results in interference in calculating the Doppler shift frequency from the backscattering components. ...

Segmental testicular infarction (STI) is a rare cause of acute scrotum. The spectrum of findings on gray-scale and color Doppler ultrasonography differ depending on the time between the onset of testicular pain and the ultrasonography examination. We are not aware of the usefulness of shear-wave elastography for the diagnosis of STI. We report the shear-wave elastography features in a case of S...

OBJECTIVE To determine the accuracy of Doppler ultrasound in the diagnosis of endometrial carcinoma in patients presenting with post-menopausal bleeding while taking histopathological findings as the gold standard. METHODS The cross-sectional study was done at the Department of Radiology, Bahawal Victoria Hospital, Bahawalpur, from April 1 to September 30, 2009, and comprised 128 patients abo...

100 patients coming to JSS with scrotal pain between November 2011 and August 2014 were studied. Each patient was examined in multiple planes using 7.5MHz-10MHz variable frequencies with colour and pulse Doppler 5MHz frequency probe was used in a few cases who had large scrotal mass. Most of the patients in our study belong to age group between 20-40 years (68%).In our study, Inflammatory condi...

BACKGROUND Differential diagnosis of ovarian masses can influence both treatment selection and prognosis of ovarian tumor patients. A comprehensive review was performed with respect to the diagnostic value of conventional ultrasonography, Doppler ultrasonography and contrast-enhanced ultrasonography (CEUS) in differentiating benign from malignant ovarian masses. METHODS Databases were searche...
