[Topographic diagnosis in the area of the head-neck: initial experiences comparing ultrasound panorama images with CT and MRI].
OBJECTIVE
Due to the restricted width of the ultrasound array, documentation of topographical correlations in B-scan-echography is still difficult. By means of Color SieScape it is possible to produce successive images of the regions of interest by lateral movement of the ultrasound array. Aim of the present study was to evaluate this new method in comparison to CT and MRI.


METHODS
18 patients with tumors in different areas of the head and neck region were examined by CT or MRI and by sonography. Color SieScape was used for documentation. A Sonoline Elegra ultrasound platform with 7.5 MHz linear array was used for the investigations.


RESULTS
Because of claustrophoby no MRI-investigation could be done in 4 of the patients. Sonography and Color SieScape documentation was possible in all cases. In addition to the panorama-information of SieScape technique in every investigation by Color SieScape large and very small vessels could be documented in colour.


CONCLUSIONS
By the use of Color SieScape the identification of the topographical correlations is improved. The spatial resolution is comparable to MRI and better than in CT. Investigation of patients who suffer from claustrophobia is much easier by Color SieScape. The imaging of parapharyngical structures could not be improved by Color SieScape. Nevertheless it is the only technique for the coloured documentation of even small vessels and topographic relations. Color SieScape investigations are faster and less expensive than CT or MRI.
