Colour Doppler sonography in breast tumours: an update
European Radiology, 1998The aim of our study was to reassess the diagnostic performance of image-based, computer-assisted colour Doppler quantification under routine conditions. We used a computer-assisted protocol that quantitatively characterises a colour Doppler image by the relative amount of colour pixels (colour pixel density, CPD) and the colour hues (numerically ...

Colour doppler imaging for diagnosis of intracranial hypotension
The Lancet, 1999Measurement of CSF pressure is the only known way to confirm the diagnosis of intracranial hypotension. We aimed to assess colour doppler flow imaging (CDFI) for measurement of blood flow of the superior ophthalmic vein for the diagnosis of intracranial hypotension.We enrolled 25 consecutive patients with orthostatic headache who had clinical features ...

Colour doppler flow imaging of the carotid arteries
Neuroradiology, 199153 patients with carotid artery atherosclerosis were examined by colour Doppler flow imaging. These results were compared with real time duplex sonography and continuous wave Doppler sonography. In 48 low degree stenoses (less than 50%) the B-mode showed 36 smooth and 12 ulcerated plaque surfaces.

Colour Doppler imaging of the acute paediatric scrotum
Pediatric Radiology, 1993The differentiation of the causes of acute scrotal pathology by clinical means alone is prone to inaccuracy, resulting in inappropriate surgical exploration. Colour Doppler imaging (CDI) provides the facility to assess blood flow. Torsion of the testis impedes blood flow, whereas it is enhanced or normal in inflammatory pathology.

Colour Doppler imaging of the interspinous and epidural space
European Journal of Anaesthesiology, 2001In recent studies, ultrasonic diagnostic imaging has proved useful in the screening of the trajectory of the epidural needle. With regard to possible side-effects of spinal and epidural anaesthesia caused by vessel injury, we aimed to evaluate the usability of Colour Doppler imaging for the depiction of interspinous vessels in prepuncture examination ...

Colour Doppler Analysis of Tendon and Muscle Movements
Journal of Hand Surgery, 1998We have examined and successfully visualized active and passive movement of tendons and muscles using colour Doppler ultrasound. This preliminary study suggests that colour Doppler may be very useful to examine the movements of tendons and muscles.

Colour Doppler sonography of the normal paediatric testis
Clinical Radiology, 1994Colour Doppler imaging (CDI) potentially provides the facility to differentiate torsion of the testis from inflammatory pathology. Normal control data are required for the purposes of interpretation of abnormal findings. Fifty boys with normal testes were examined by CDI using the Acuson 128XP System.

Colour Doppler Sonography in Obstetrics
2017The minimum frequency of transducer should be 7.5 MHz in early pregnancy (up to 8 weeks) and 5 MHz in 9–13 weeks of pregnancy. A duplex Doppler or a triplex Doppler capability is essential for displaying Doppler waveforms and for calculating the resistance index (RI) and pulsatility index (PI) and also the A/B ratio (peak systolic/end diastolic ratio).

Colour Doppler flow imaging of the orbital veins
Acta Ophthalmologica, 1992Abstract Experience is given from 79 orbital lesions examined by Colour Doppler Flow Imaging (CDFI) Dec. 1990 to Febr. 1992. We further examined 167 ocular tumours, or tumourlike lesions, and 32 ophthalmic cases groupes as ‘various’. Here, our experience is summarized concerning the flow patterns demonstrated in orbital veins, pathologic and normal ...
