Originální abstrakt

The paper deals with the post-processing treatment of MR images in the examina- tion of temporomandibular joints. An increase in contrast corresponding to the relaxation time of cores T2 in the MR image and enhancement of arthritic areas of diseased temporomandibular joint were obtained by wavelet transform digital filtering and by processing two MR images measured at difeerent echo times. The enhanced area indicates arthritic changes in the temporomandibular joint, which will be compared with the results of arthroscope examination. Experimental verifica- tion of the described method of data processing shows the application of wavelet digital filtering to be of advantage. Images weighted by relaxation time T2 enhance the loosely bonded molecules of water and enable making the area with arthritic changes in temporomandibular visible. The method can also be applied in other MR examinations.
