Ever increasing number of radiology images makes their storage and classification a challenging issue. In this paper a new method for compression and retrieval of radiology images in HEVC compressed domain is introduced. In this method the radiology images are coded as I-frames in HEVC standard. The prediction mode histogram along with PU size histogram of the coded images are used for classification and retrieval of radiology images. Experimental results indicate that the proposed method achieves in average 95% accuracy in classification and P@35 of 89% for radiology images which are superior to the other methods.
